Description

  TECHNICAL FIELD The present invention relates to a fiber plating jig and a fiber plating method using the same, and more particularly to downsizing a fiber plating facility and a fiber to be plated (the filament itself and / or several to several thousand). The time required for fiber plating is shortened and the fiber plating is efficiently carried out by making the length immersed in the plating solution of the fiber bundle of the filaments of which the filaments are gathered (the same shall apply hereinafter) longer than before. Regarding technology.

  As a conventional technique of this type, a fiber bundle continuous plating apparatus disclosed in Patent Document 1 is known. This continuous plating apparatus is intended to efficiently and efficiently produce a fiber bundle in which electroless plating or electroplating is uniformly applied to each fiber, and includes an etching part, a neutralization part, a surface adjustment part, A winding part, a catalyst part, an accelerator part, an electroless plating part, a pickling part, a first electroplating part, and a second electroplating part are provided, and each part is processed by a linear processing tank.

JP 2003-183886

  However, in the continuous plating apparatus disclosed in Patent Document 1, since the fiber to be plated immersed in the treatment tank for treating the fiber to be plated is set in a linear shape, the plating tank (hereinafter simply referred to as “plating”). The tank is required to be linear, and the length of the tank is several meters to several tens of meters (3 m to 70 m). Therefore, there is a problem that a large installation area is required as a place for installing the fiber plating apparatus. In addition, since there is a limit to increasing the size of the apparatus, the length of the fiber to be plated that can be immersed at one time is naturally limited. Therefore, there is a problem that even if a plating apparatus of 3 m to 70 m is used, the fiber can only be plated at a speed of 0.5 m per minute. In the case of the continuous plating apparatus disclosed in Patent Literature 1, for example, when the fiber to be plated is sent out by a pinch roller having a diameter of 60 mm, the same result is obtained that only 180 mm can be immersed in one rotation.

  Furthermore, the continuous plating apparatus disclosed in Patent Document 1 has a large area where the fiber to be plated contacts with the guide roller because the guide roller is provided in the plating tank in the order of right → left → right → left. The fiber is easily pulled. For this reason, there is a problem in that the fiber to be plated is overloaded and the filament constituting the fiber is likely to be broken, and when the filament breakage is further increased, the yarn becomes weak and develops into yarn breakage.

The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the time required for fiber plating and efficiently perform fiber plating while reducing the size of the fiber plating apparatus. It is in providing the fiber plating jig which can be manufactured, and the fiber plating method using the same.
Another object of the present invention is to provide a fiber plating jig that can prevent filament breakage and thread breakage, and a fiber plating method using the same.

In order to solve the above problems, the fiber plating jig according to the present invention is:
The gist of the present invention is a fiber plating jig that rotates about a rotation axis and has the following configuration.
(1) The fiber plating jig is
The rotating shaft;
Hanging means for spirally winding the fiber to be plated around the rotation axis;
Supporting means for supporting the hanging means and attaching the hanging means to the rotating shaft;
It has.
(2) The hanging means is
(A) An opening slit is formed at the tip thereof, and a hanging recess for hanging the to-be-plated fiber, having a portion that gradually becomes narrower toward the opening slit, or
(B) A hanging for hanging the to-be-plated fiber, which has an opening slit at its tip, has a bent shape or a bent shape, and has a non-curved surface formed on its inner peripheral surface Recess,
It has.
(3) the entraining hand stage is arranged before Symbol rotation axis on the circumference whose center, and, as the opening slit is-out outward with respect to the rotation axis, mounted on said rotary shaft ing.

According to the fiber plating jig having the above-described arrangement, the entraining means, Bei give a portion to be a gradually narrower, and hung recess opening slits are formed, or, the bent shape or bent shape It is provided and the non-curved portion is formed, entraining recess to be plated fibers are hung a further entraining recess opening slit bets are formed, or, C-type hanging to be plated fibers are hung A stand is provided . Then, the entraining means comprising said entraining recess or C entraining portion is disposed on a circle centered on the rotation axis, and, in the opening slit outwardly with respect to said rotation axis It is formed. Accordingly, the tip of the fiber to be plated is attached to the winding device on the end side, and is drawn out and hung on the hanging recess or the C-type hanging portion, and the hanging recess or C-type hanging portion is sequentially spiraled. The to-be-plated fiber is wound around the fiber plating jig by hanging on the frame.

  Then, attach the plating start part of the fiber to be plated to the delivery device on the start side, immerse the fiber plating jig around which the fiber to be plated is wound in the plating solution, and synchronize the delivery device, rotating shaft and winding device. When operated, the fiber plating jig rotates, and the plating process is completed when a predetermined time elapses.

In this case, the hanging means is
A bent portion or a bent shape is formed, a non-curved surface portion and a facing portion formed to be inclined with respect to the non-curved surface portion are formed, and a hanging concave portion having an opening slit formed at the tip thereof is further provided. Thing or
A bent portion or a bent shape is formed, a non-curved surface portion and a facing portion formed to be inclined with respect to the non-curved surface portion are formed, and a hanging concave portion having an opening slit formed at the tip thereof is further provided. met with, which chamfered portion chamfered corner between the outer periphery of those opening slit and the hung hand stage is formed as
It may be.

  In this case, the interval in the vertical direction (direction parallel to the rotation axis) of the hanging recess or the C-shaped hanging portion can be adjusted according to the thickness of the yarn and the number of filaments, but is preferably 1 mm to 10 mm. This is because if the interval is too narrow, it is difficult to hang the fiber to be plated, and if the interval is too wide, the efficiency of the fiber plating is adversely affected. The length of the hanging means is preferably 100 mm to 1500 mm, and more preferably 300 mm to 1000 mm. This is because if the length is too short, the amount of fiber plating decreases, and if it is too long, a large amount of plating solution is required, which is not practical. The diameter of the hanging means (referring to the diameter of the portion where the fiber to be plated is hung) is preferably 240 mm to 1100 mm, and more preferably 340 mm to 500 mm. This is because if it is too small, the amount of fiber plating decreases, and if it is too large, an installation area is required and a large amount of plating solution is required, which is not practical.

The above-described fiber plating jig according to the present invention further includes:
It is preferable to provide support means for attaching and supporting the hanging means, and surrounding the rotation shaft around the rotation shaft and arranged parallel or obliquely to the rotation shaft.
In this case, it is preferable that the hanging recess is formed in parallel or inclined with respect to the thickness direction when the hanging means is a plate-like member. Although the fiber to be plated is hung on the fiber plating jig in a spiral shape, when the hanging recess is formed to be inclined with respect to the plate thickness direction, the inclined direction can be adjusted to the spiral direction. This is because the fiber to be plated can be smoothly fed out, plated, and wound while preventing filament breakage and thread breakage.

  It is preferable that the C-shaped hanging portion is formed of a cross-sectional circle or an elliptical member and is integrally formed with the support means. The fiber to be plated is hung on the fiber plating jig in a spiral shape. However, if the C-shaped hanging part is a cross-sectional circle or an elliptical member, the fiber to be plated is prevented while preventing filament breakage or thread breakage of the fiber to be plated. This is because it can be smoothly fed out, plated, and wound up.

Preferably, the hanging means of the fiber plating jig according to the present invention is made of titanium, and the hanging concave portion is formed by etching. This is because titanium is excellent in corrosion resistance. Etching is preferable because the corners of the hanging recesses can be rounded, so that filament breakage and thread breakage can be prevented.
The fiber plating jig according to the present invention preferably has a vertical and horizontal size (size to which a hanging means is attached) within 5000 mm. This is because it is possible to achieve more than twice the conventional plating efficiency while significantly reducing the installation area.
The gist of the fiber plating method according to the present invention is to perform electroless plating or electrolytic plating using the fiber plating jig.

Fibers plating jig of the present invention is made to rotate about a rotation axis, Bei give a portion to be a gradually narrower, and hung recess opening slits are formed, or, bending shape or and non-curved section comprising a bent shape is formed, entraining recess to be plated fibers are hung a further entraining recess opening slits are made form, or be plated fibers are hung A hanging portion of the to- be-plated fiber provided with a C-type hanging portion, and a hanging concave portion or a C-type hanging portion of the hanging means is arranged on a circumference around the rotation axis; Since the opening slit is formed outward with respect to the rotation axis, the installation area of the plating tank which has conventionally required several tens of meters can be made within 5000 mm in length and width, so that the fiber plating apparatus can be downsized. be able to.

  In the fiber plating jig according to the present invention, the fiber to be plated is hung on the hanging concave portion or the C-shaped hanging portion, and is sequentially hung on the hanging concave portion or the C-shaped hanging portion in this state. In this case, the plating is started. However, by adjusting the rotation speed at the time of plating, there is an effect that the time required for the fiber plating can be shortened and the fiber plating can be efficiently performed. Further, if the tension of the fiber to be plated when the fiber to be plated is hung on the hanging recess or the C-shaped hanging portion is loosened, there is an effect that filament breakage and thread breakage can be prevented.

Fibers plating jig according to the present invention, and non-curved section comprising a bent shape or bent shape is formed, to further comprising a hung recess opening slit bets is formed, the plated fibers in entraining recesses There is an effect that it is wound in parallel at the non-curved surface portion without being bundled and can be smoothly plated.

The fiber plating jig according to the present invention can increase the amount of fibers that can be plated at one time by narrowing the interval between the hanging recesses or the C-shaped hanging portions or increasing the length of the hanging means. As a result, the time required for the fiber plating can be shortened and the fiber plating can be efficiently performed. Furthermore, adjustment of the interval between the hanging recesses or the C-shaped hanging portions and the length of the hanging means has an effect of promoting effective use of the installation area.
In addition, the fiber plating jig according to the present invention can increase the amount of fiber that can be plated at one time even if it is smaller than the same installation area as the conventional one, so the time required for fiber plating is shortened and the fiber is efficiently There is an effect that plating can be performed.
The fiber plating method according to the present invention uses the fiber plating jig according to the present invention, and therefore has the same effect as described above.

It is an appearance perspective view of a fiber plating jig concerning one embodiment of the present invention. It is the upper side figure and front view of the fiber plating jig which concern on one Embodiment of this invention. The figure (a) is a front view of the hanging board attached to the fiber plating jig concerning one embodiment of the present invention, and the figure (b)-(e) is an enlarged view of the hanging concave part concerning each embodiment. is there. It is a figure which shows the process of the fiber plating method which concerns on one Embodiment of this invention.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
(Fiber plating jig)
FIG. 1 is an external perspective view of a fiber plating jig 10 according to an embodiment of the present invention, FIG. 2 is a top view and a front view thereof, and FIG. 3 (a) and FIG. It is a front view which expands and shows the hanging board. In these figures, a fiber plating jig 10 is used by immersing it in a plating tank (electroless plating tank, electrolytic plating tank) filled with a plating solution in a state where a fiber to be plated is wound around the jig. By rotating around the rotating shaft 14 by control, new plated fibers are sequentially immersed in the plating solution and the plated fibers are sent to the next processing.

  The fiber plating jig 10 includes a hanging plate 12, a rotating shaft 14, and a rack body 16. The fiber plating jig 10 can have a vertical and horizontal size (referred to as a size with the hanging plate 12 attached, hereinafter the same) within 5000 mm from the viewpoint of the installation area, but is preferably within 3000 mm, more preferably within 1100 mm. More preferably, 500 mm or less is more preferable. However, from the viewpoint of plating efficiency, the vertical and horizontal sizes should be 240 mm or more, more preferably 340 mm or more. Further, the length of the hanging plate 12 of the fiber plating jig 10 needs to be 100 mm or more from the viewpoint of plating efficiency, but is preferably within 1500 mm in consideration of plating work and maintenance work. Particularly preferable sizes of the fiber plating jig 10 are 300 mm to 400 mm in length, 300 mm to 400 mm in width, and 300 mm to 1000 mm in height (the same as the height of the hanging plate 12).

  The rotating shaft 14 is a rotating body that rotates the fiber plating jig 10 including the rack body 16, the support skeleton 16 c, and the hanging plate 12. The rotating shaft 14 is used by being immersed in a plating solution. Accordingly, the material of the rotating shaft 14 is not particularly limited as long as the rotating shaft 14 does not cause a chemical reaction with the plating solution or has been processed so as not to cause a chemical reaction, and is a hard material. Further, a non-conductive resin film (such as a film formed by applying a sol obtained by mixing a pigment with vinyl chloride resin, a Teflon film, a polyethylene film, or the like) on a metal (for example, copper) is used. The rotation speed of the rotation shaft 14 is controlled by a control device (not shown).

  The rack body 16 is made of a cylindrical or prismatic skeleton. The material of the rack body 16 is not particularly limited, and various materials such as metal and polymer resin can be used. However, in the present embodiment, a copper flat plate or a round bar is preferable (in this case). In the case of electroless plating, a non-conductive resin film similar to the above is formed). Although a flat plate is preferable in terms of workability, FIG. 1 shows an example of a round bar. The rack body 16 includes a radial skeleton 16a, an outer peripheral skeleton 16b, and a support skeleton 16c.

In the present embodiment, the radial skeleton 16a and the support skeleton 16c are made of the same member. That is, the radial skeleton 16a extends radially from the upper part of the rotating shaft 14 and bends in the vertical direction with a predetermined length (generally, slightly smaller than the radius of the rack body 16) to form the support skeleton 16c. The support skeleton 16c extends in the vertical direction and bends in a horizontal direction opposite to the previous horizontal direction by a predetermined length (generally a little smaller than the length in the longitudinal direction of the hanging plate 12). Become. The radial skeleton 16 a extends toward the rotation shaft 14 and is connected to the rotation shaft 14.
The outer peripheral skeleton 16b has various fixing methods such as a chemical method such as welding / adhesion, a mechanical method such as screwing / engaging, and other methods at a bent portion that is a boundary between the radial skeleton 16a and the support skeleton 16c ( Hereinafter, the term “various fixing methods” is used in the same meaning) to attach or join in the vicinity of the bent portion. The radial skeleton 16a is attached or joined to the rotating shaft 14 by various fixing methods.

  That is, in the present embodiment, the eight radial skeletons 16a extend radially from the two upper and lower portions of the rotating shaft 14 at equal angular intervals. A plurality of (eight) support skeletons 16 c are provided around the rotation shaft 14 around the rotation shaft 14 at intervals of 45 degrees, and are arranged in parallel with the rotation shaft 14. The support skeleton 16c attaches the support plate 12 and supports it. Since eight support skeletons 16c are provided, the hanging plates 12 are also referred to as a first hanging plate to an eighth hanging plate in the adjacent order.

The hanging plate 12 (the first hanging plate to the eighth hanging plate) is made of a planar or curved plate member, and is made of metal (non-conductive resin in the case of electroless plating). Coating), a polymer resin or the like can be applied, and is not particularly limited. When this is made of a flat plate-like member, the hanging plate 12 preferably has a plate thickness of 1 mm to 5 mm, a plate width of 20 mm to 50 mm, and a plate length of 100 mm to 1500 mm (preferably 300 mm to 1000 mm). The reason why the plate thickness is in this range is that if the thickness is too thick, the fiber to be plated becomes stepped, and if it is too thin, the strength of the plate becomes weak. The reason why the plate width is set in this range is that an attachment portion for attaching the hanging plate 12 to the fixed plate 18 is required. The reason for setting the plate length within this range is from the viewpoint of plating efficiency.
Since the hanging plate 12 is immersed in the plating solution, it is preferable that the surface treatment is performed so as not to cause or cause a chemical reaction with the plating solution. In this embodiment, the conductivity is not good but the corrosion resistance is good. Titanium is used. The hanging plate 12 may be made of stainless steel other than the acidic bath.

Entraining plate 12 Bei give a portion to be a gradually narrower, and hung recess 12b which the plated fibers are hung a hung recess 12b of apertures slits 12a are formed is arrayed Yes. Entraining recess 12b is a through-hole formed in parallel or inclined with respect to the thickness direction, a through-hole with apertures slit 12a. The shape of the hanging recess 12b is not particularly limited as long as it does not have a sharp portion in the inner circumferential direction and the plate thickness direction from the viewpoint of preventing filament breakage and thread breakage, and has a gradually narrowing portion. Instead, a circular shape, an elliptical shape, a polygonal shape with rounded corners, and other curved / curved surface shapes can be adopted. The reason why the gradually narrowing portion is formed in the hanging recess 12b is to prevent the fiber to be plated from coming off from the hanging recess 12b during the plating process. As shown in FIG. 3, the hanging recess 12b is circular, and its arc gradually becomes narrower toward the opening slit 12a.

In the present embodiment, since the hanging recess 12b is formed by etching, it is formed in parallel with the thickness direction, and the corners in the thickness direction of the hanging recess 12b are rounded. The etching process is performed, for example, by spraying a fluoride-based liquid.
Instead of the hanging recess 12b, a C-shaped hanging portion (not shown) made of a cross-sectional circle or an elliptical member may be formed directly and integrally with the support skeleton 16c. In this case, the C-shaped hanging portion is preferably made of the same type of metal if the support skeleton 16c is made of metal, and is made of the same type of polymer resin if the support skeleton 16c is made of a polymer resin. Is preferred.

  The interval in the longitudinal direction (direction parallel to the rotation shaft 14) of the hanging recess 12b or the C-shaped hanging portion (distance between the same positions of the adjacent hanging recess 12b or the C-shaped hanging portion) is 1 mm to 10 mm is preferred. This is because if the interval is too narrow, the efficiency of the work of hanging the fiber to be plated is adversely affected and the plating around the inner surface side (side facing the rotating shaft 14) of the fiber to be plated is deteriorated. On the other hand, if the interval is too wide, the efficiency of fiber plating is adversely affected. The length of the hanging plate 12 is preferably 100 mm to 1500 mm, and more preferably 300 mm to 1000 mm. This is because if the length is too short, the amount of fiber plating decreases, and if it is too long, a large amount of plating solution is required, which is not practical.

  The hanging plate 12 is attached by using a fixing plate 18 that is attached to the support skeleton 16c at an appropriate interval. The fixing plate 18 is formed with fixing holes 18a, 18a... And the hanging plate 12 is attached to the support skeleton 16c at the fixing holes 18a, 18a. Accordingly, the hanging plate 12 is positioned along the support skeleton 16c using the fixing plate 18 and is attached at the fixing hole 12c formed on the opposite side of the hanging recess 12b. The opening slit 12a is formed outwardly with respect to the rotation shaft 14 and is arranged on a circumference centering on the rotation shaft 14. Also in the case of the C-type hanging portion, the opening slit 12a is formed outward with respect to the rotating shaft 14.

  As described above, the hanging recess 12b or the C-shaped hanging portion is disposed on the circumference around the rotation shaft 14 of the hanging plate 12, and the opening slit 12a faces outward with respect to the rotation shaft 14. Therefore, the tip of the fiber to be plated is attached to the winding device on the end side, and this is fed out and hung on the hanging recess 12b or the C-shaped hanging portion, and then the hanging recess 12b or The fiber to be plated is wound around the fiber plating jig 10 by hanging on the C-shaped hanging portion.

  Then, the plating start portion of the fiber to be plated is attached to the start-side delivery device, the fiber plating jig around which the fiber to be plated is wound is immersed in the plating solution, and the delivery device, rotating shaft, and winding device are synchronized. When operated while taking, the fiber plating jig 10 rotates, and the plating process is completed when a predetermined time elapses. When the fiber to be plated is wound around the fiber plating jig 10 and plating is performed, the plating amount per rotation can be adjusted only by adjusting the diameter of the rack body 16 even if the rotation speed of the servo motor is the same. . For example, when the rack body 16 has a diameter of about 300 mm, an effect similar to that of immersing a fiber to be plated of about 1 m in one rotation can be obtained.

  When the hanging recess 12b is formed to be inclined with respect to the plate thickness direction, the hanging recess 12b is inclined along the spiral direction of the to-be-plated fiber hung on the hanging recess 12b. In this case, a technique such as etching is performed with the hanging plate 12 inclined at a predetermined angle so that the through-hole is formed in an oblique direction in the etching process.

  In a fiber plating facility (not shown) where the fiber plating jig 10 is installed, although not shown, a plating tank (not shown) provided with an anode, a filter, a heater, an air blow, a sub tank, and an ultrasonic device, Servo motors on the start side (feed side) and end side (winding side) are provided.

  For the anode, a copper plate, a copper tip, a nickel plate, a nickel tip, or the like is used. The copper plate and the nickel plate are attached to the inner wall surface of the plating tank, and the copper chip and the nickel chip are accommodated in a cage made of a titanium case and put into the plating tank. The cathode is made of a fiber to be plated, and is electrically energized via the hanging plate 12 and the rotating body 14. The filter is provided with a filter, and the plating solution is circulated to remove dirt in the solution. As the heater, Teflon, quartz, stainless steel, titanium, or the like can be used, and the heater is selected depending on the type of plating solution. Since the quartz heater breaks when it collides with the rack body 16, a protective tube is provided. The protective tube is a perforated vinyl chloride pipe.

  The air blow is for creating air bubbles by sending air in order to stir the plating solution, and a blower for sending out air covered with a vinyl chloride pipe or the like having a small hole is submerged in the plating solution. The sub tank is for replenishing the plating solution with the chemical supplied to the plating tank after heating the plating solution and replenishing the chemical with the plating solution, and preferably has a larger size than the plating tank. The ultrasonic device is used to improve the area around the plating, and is installed so that the ultrasonic wave strikes the side surface of the rotating shaft 14 in the plating tank. This is because, by applying ultrasonic waves to the fiber to be plated, the fiber to be plated is vibrated to promote the penetration of the plating solution. Each servo motor is inverter-controlled by a servo amplifier, and performs rotation control of a bobbin for feeding out or winding up the fiber to be plated. Each servo motor is phase-controlled so that the wound fiber to be plated has an appropriate slack.

(Second embodiment)
As shown in FIG. 3C, the second embodiment is a bent or bent shape, for example, an L-shaped hanging concave portion 22b, in which a non-curved surface portion 22c is formed and opened. The hanging recess 22b in which the mouth slit 22a is formed is shown. Due to the bent shape or the bent shape, the fiber to be plated is not easily detached from the hanging recess 22b. By forming the non-curved surface portion 22c, the fibers to be plated are wound in parallel. Here, the “non-curved surface portion” refers to a planar portion / linear portion where no concave portion or convex portion is formed, and the surface direction / linear direction is not particularly limited as long as it is planar (the same applies hereinafter). The non-curved surface portion can be set in the vertical direction, for example . The hanging recess 22b is formed in parallel or inclined with respect to the plate thickness direction. Since the other points are the same as those in the first embodiment, the description is replaced with the description in the second embodiment.

(Third embodiment)
As shown in FIG. 3D , the third embodiment shows a hanging recess 32b that is a bent or bent hanging recess 32b and is formed with a non-curved surface 32c. In the hanging recess 32b, a facing portion 32d facing the non-curved surface portion 32c is formed to be inclined with respect to the non-curved surface portion 32c toward the opening slit 32a . The facing portion 32d is inclined so that the hanging recess 32b becomes gradually narrower. Since the bent fiber or bent shape does not easily remove the fiber to be plated from the hanging recess 32b, the facing portion 32d is inclined, so that it is difficult to come off more than necessary due to being caught at the bent or bent portion. Don't be . The hanging recess 32b is formed in parallel or inclined with respect to the plate thickness direction. Since the other points are the same as in the first embodiment, the description is replaced with the description in the third embodiment.

(Fourth embodiment)
As shown in FIG. 3E, the fourth embodiment shows a hanging recess 42b having a bent shape or a bent shape and having a non-curved surface portion 42c and an inclined portion 42d. . In the hanging recess 42b, a facing portion 42d facing the non-curved surface portion 42c is formed to be inclined with respect to the non-curved surface portion 42c toward the opening slit 42a . The facing portion 42d is inclined so that the hanging recess 42b gradually becomes narrower. Since the bent fiber or the bent shape does not easily remove the fiber to be plated from the hanging concave portion 42b, the facing portion 42d is inclined, so that it is difficult to come off more than necessary due to being caught at the bent or bent portion. Don't be. Further, a chamfered portion 42e formed by chamfering a corner portion between the opening slit 42a and the outer periphery of the hanging plate 12a is formed in the opening portion of the opening slit 42a. While the chamfered portion 42e facilitates the work of hanging the fiber to be plated, the yarn is not easily damaged when the yarn is detached from the opening slit 42a at the end of plating . The hanging recess 42b is formed in parallel or inclined with respect to the plate thickness direction. Since the other points are the same as in the first embodiment, the description is replaced with the description in the fourth embodiment.

Next, a fiber plating method using the fiber plating jig 10 according to an embodiment of the present invention will be described.
(Fiber plating method)
The fiber plating jig according to one embodiment of the present invention and the fiber to be plated that can be plated using the fiber plating method include polymer fiber materials (aromatic polyamide (polyparaphenylene terephthalamide), polyester, Examples include, but are not limited to, para-type aramid fibers (copolyparaphenylene 3,4′oxydiphenylene terephthalamide), glass fibers, alumina fibers, carbon fibers, and other organic and inorganic polymer fiber materials). It is not something.

  Table 1 shows a fiber plating method according to an embodiment of the present invention and a fiber to be plated suitable for the method. In the fiber plating method according to the first and third methods, the fiber to be plated is loosened to a liquid-permeable or gas-permeable (for example, lattice-like or mesh-like) cylindrical core made of polymer resin (for example, polypropylene). This is a method suitable for application to a winding cylinder (hereinafter also simply referred to as “soft winding cylinder”) in which the fiber to be plated is wound softly. In the fiber plating method according to the second and fourth methods, a fiber to be plated (thread-like fiber to be plated is connected with a dummy fiber, hereinafter also simply referred to as “yarn”) is used as a bobbin to bobin. Or it is a method suitable when plating while feeding by reel to reel (reel to reel). Here, the reason why the dummy fibers are connected is that, at the start of plating, fibers that do not pass through each processing step or fibers that cannot be immersed in the plating solution appear, so that the portion is not wasted.

(First method)
(1) A soft winding process is a process of producing a soft winding cylinder. When producing the soft winding cylinder, the plating solution is wound loosely so as to penetrate into the fiber to be plated.

(2) The scouring step is a step of treating the soft winding cylinder with a scouring agent. This prevents fibrillation of the fiber to be plated and prevents reattachment of oils and dirt. As the scouring agent, for example, caustic soda, nonionic surfactant, organic solvent and the like can be used, but not limited thereto. After the treatment with the scouring agent, the soft winder is washed with water in a flowing water tank. This removes excess deposits on the polymer fibers. The scouring step can be omitted when the oil to be plated is not attached with oil or dust or when it is not charged.
According to the scouring process, as shown in FIG. 4 (a), oil, dust and the like are removed from the surface of the polymer fiber.

(3) The etching step is a step of removing the surface inclusions and layers by corroding the plated fiber to make the surface of the plated fiber hydrophilic. For example, it is possible to use a technique of immersing the soft winding cylinder in a 1 g / L caustic soda solution at 70 ° C. for 10 minutes, but this is not limitative. After the etching process, the soft winding cylinder is submerged in a flowing water tank and washed. This removes excess deposits on the polymer fibers. According to the etching process, as shown in FIG. 4B, the surface of the polymer fiber is hydrophilized.

(4) The surface adjustment step is a step of making the core of plating easy to attach to the surface of the fiber to be plated by cationizing the fiber to be plated. For example, a method of immersing the soft winding tube in a cationic surfactant solution can be used, but the method is not limited to this. After the surface adjustment treatment, the soft winder is washed with water in a flowing water tank. According to the surface adjustment step, the surface of the polymer fiber is cationized as shown in FIG.

(5) The catalyst imparting step is a step of adsorbing and binding a catalytic metal colloid that serves as a plating nucleus on the surface of the fiber to be plated. For example, a technique of immersing a soft winding cylinder in a catalyst solution can be used, but the present invention is not limited to this. As the catalyst solution, for example, a colloidal solution of Pd and Sn can be used. This solution was prepared by mixing tin (II) chloride and palladium (II) chloride dissolved in a hydrochloric acid solution with stirring and aging with heating. After the catalyst application treatment, the soft winding tube is washed with water in a flowing water tank. According to the catalyst application step, as shown in FIG. 4D, the catalytic metal colloid is adsorbed and bonded to the surface of the cationized polymer fiber. This adsorption / bonding is caused by, for example, van der Waals force or Coulomb force.

(6) The accelerator step is a step of generating a catalytically active metal on the surface of the fiber to be plated. For example, by immersing a soft winding tube in an acid solution, the adsorbed catalytic metal colloid, for example, Sn out of Pd and Sn is dissolved, and catalytically active Pd is generated by oxidation-reduction reaction, which is then applied to the surface of the fiber to be plated It is the process of generating. The acid solution is not particularly limited as long as it is an acid that dissolves Sn but does not dissolve Pd, and the concentration, temperature, and treatment time are not particularly limited. Examples of suitable acid solutions include hydrochloric acid (10%, room temperature, 5 minutes), sulfuric acid (10%, 45 ° C, 5 minutes), hydrofluoric acid (5%, room temperature, 5 minutes), borohydrofluoric acid ( 5-10%, room temperature, 5 minutes). After the accelerator treatment, the soft winding cylinder is submerged in a flowing water tank, washed with water, and further centrifuged. According to the accelerator process, as shown in FIG. 4E, a catalytically active metal is generated on the surface of the fiber to be plated.

(7) In the electroless plating process, a plating film is formed on the fiber to be plated by immersing the fiber plating jig 10 around which the fiber to be plated is wound in a plating tank (diameter 400 mm to 1200 mm) filled with a plating solution. It is a process to make. Here, in electroless plating, the metal ions contained in the plating solution are reduced by electrons released when the reducing agent contained in the plating solution is oxidized, and the metal is deposited on the object to be plated as a metal film. Is the method. A film with a uniform thickness can be obtained regardless of the shape and type of the material. Examples of the electroless plating that can be used in the present embodiment include electroless copper plating, electroless nickel plating, electroless silver plating, and electroless tin plating, but are not particularly limited (see Table 2).

  The electroless plating process in the present embodiment is characterized in that the fiber plating jig 10 can be used. That is, a dummy fiber is connected to a fiber to be plated (thread-like), and the tip of the dummy fiber is wound around a bobbin or a reel on the winding side (end side). The reason why the dummy fibers are connected is that fibers that cannot be immersed in the plating solution appear at the start of plating, so that the portion is not wasted. Next, allow the yarn enough to pass through each facility of water washing and warm air drying, dummy fiber (if the fiber to be plated comes out past the joint, shows the fiber to be plated, hereinafter simply Is wound around each of the hanging plates 12, 12... Of the fiber plating jig 10 so as to draw a spiral. That is, the thread is hung on the hanging recess 12b of the first hanging plate 12, and then hung in a helical manner on the hanging recess 12b of the second hanging plate 12 adjacent to the first hanging plate 12, In the following order, the hanging recess 12b of the third hanging plate 12, the hanging recess 12b of the fourth hanging plate 12, the hanging recess 12b of the fifth hanging plate 12, and the hanging recess 12b of the sixth hanging plate 12 are arranged. By hanging in a spiral manner on the hanging recess 12b of the seventh hanging plate 12, the hanging recess 12b of the eighth hanging plate 12, and returning to the hanging recess 12b of the first hanging plate 12. Then, it is wound around the fiber plating jig 10. Then, a yarn serving as a start portion to be subjected to processing is wound around a bobbin or a reel on the feed side (start side).

  Then, the fiber plating jig 10 wound with the yarn is immersed in a plating tank filled with the electroless plating solution, and the fiber plating jig 10 and the bobbin or reel on the feeding side and the winding side are rotated while being synchronized. Then, the yarn is sequentially immersed in the electroless plating solution for a predetermined time. Thereby, a plating film is formed on the yarn. After the electroless plating treatment, the yarn has enough space to pass through the water washing treatment equipment and hot air drying treatment equipment. The air drying process is completed, and then the plated yarn is wound up by the bobbin or reel on the winding side. According to the electroless plating treatment, a plating film is generated on the surface of the fiber to be plated, as shown in FIG.

(8) In the electroplating step, the fiber plating jig 10 wound with the yarn is immersed in a plating tank (diameter 400 mm to 1200 mm) filled with a plating solution, and the yarn (precisely, plating formed on the yarn) This is a step of forming a plating film on the yarn by energizing the film. Here, electroplating is a method in which a metal ion contained in the plating solution is reduced by energizing a thread as an object as an electrode, and the metal is deposited on the thread as a metal film. Examples of the electroplating usable in the present embodiment include, but are not particularly limited to, electrocopper plating, electronickel plating, electrotin plating, electrosilver plating, and electrogold plating (see Table 3).

  The electroplating process in this embodiment is the same as the above electroless plating process except that it is electroplating and the operating conditions (rotation speed, temperature, etc.) are changed depending on the case. It replaces with description of an electroplating process with description. According to the electroless plating treatment, a plating film is generated on the yarn surface as shown in FIG. The reason why the electroplating process is performed after the electroless plating process is that, by forming a metal plating film on the thread, the thread can be energized, so that electroplating with higher efficiency can be used.

(Second method)
(1) In the bobbin (reel) setting process, the thread tip is wound around a bobbin (or reel) on the winding side (end side) and each of the subsequent scouring, etching, surface adjustment, catalyst application, and accelerator In this step, the yarn is set so as to be used in the process, and is wound around a bobbin (or reel) on the start side (feed side). The second method is different from the first method in that each process is performed by a bobbin-to-bobbin or reel-to-reel without using a soft cylinder. Further, in the winding process in the accelerator process, winding is performed with a bobbin (or reel). Other than these, the following (2) scouring step, (3) etching step, (4) surface adjustment, (5) catalyst application step, (6) accelerator step, (7) electroless plating step in the second method (8) Since the electroplating step is the same as the first method, the description is replaced with the description of the second method.

(Third method)
(1) The soft winding step is the same as the soft winding in the first method.
(2) The scouring step is the same as the scouring step of the first method, but in the third method, drying (warm air drying) is further performed in a soft winding state.
(3) The supercritical nucleation treatment step is performed in a supercritical nucleation treatment apparatus at a predetermined pressure in which a metal complex (eg, Pt complex, Ni complex, Pd complex) is dissolved in a supercritical fluid (eg, CO ₂ ). This is a step of exposing the winding cylinder for a predetermined time. As a result, the metal complex is diffused into the organic polymer fiber (see FIG. 4D), and the catalytically active metal simple substance constituting the metal complex is generated in the organic polymer fiber (FIG. 4E). This is a step of generating this on the yarn surface. When this process is finished, the soft winding cylinder is taken out of the processing apparatus and used for the next processing.
Since the (4) electroless plating step and (5) the electroplating step are the same as the electroplating step of the first method, the description will be replaced with the description of the third method.

(4th method)
(1) The fiber opening and scouring step is a step of opening a flat fiber (for example, carbon fiber) to form a thread and winding it around a winding tube to produce a soft winding tube, but is not limited to this. It may be wound on a bobbin (or reel).
(2) Since the electroplating step is the same as the electroplating step of the first method, the description is replaced with the description of the fourth method.

According to the first to fourth methods described above, the following effects are obtained by using the fiber plating jig 10.
(1) If the rotational speed of the rotating shaft 14 and the rotational speed of winding are adjusted, there is an effect that plating can be performed in a state where the fiber to be plated is always loosened.
(2) If plating is performed in a loose state, there is an effect that plating can be applied to all of the filaments.
(3) If plating is performed in a loose state, there is an effect that filament breakage and thread breakage can be prevented.
(4) There is an effect that the surroundings can be further improved by setting an ultrasonic device so that ultrasonic waves hit the fiber to be plated on the side surface of the plating tank.

Since it plated using the fiber plating jig | tool which concerns on this embodiment below, it is demonstrated.
Example 1
A fiber plating jig having the same appearance as in FIG. 1 was produced. The rack body has a diameter of 400 mm and a height of 400 mm. As shown in FIG. 1, eight perforated titanium plates were attached and fixed to the fiber plating jig. There, the polyester fiber was wound as a to-be-plated fiber. The wound fiber to be plated has a diameter of 500 mm. Subsequently, copper plating was performed. As a result, a plating film having a thickness of 1 μm could be formed on the fiber to be plated at a rate of 2 m / min. In this case, the plating tank size was 600 mm in length and width and 600 mm in height.

(Comparative Example 1)
As a conventional rectangular plating tank, the length, width and height are 7000 mm x 500 mm x 300 mm, and as a service tank for supplying plating solution to this, the length, width and height are 3000 mm x 750 mm × 750 mm was prepared, and a plating tank was installed on the upper side of the service tank. And the copper provided by thread | yarn was wound on the roll provided in the plating tank. As a result, a 1 μm thick plating film could be formed on the fiber to be plated at a speed of 1 m / min.

(Evaluation)
Comparing Example 1 and Comparative Example 1, it can be seen that the plating tank of Example 1 is much more space-saving than the plating tank of Comparative Example 1. Moreover, since Example 1 was able to perform plating twice as fast as Comparative Example 1, it can be seen that shortening of plating time and efficiency can be realized.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, as the hanging means, instead of the hanging plate 12, a rail-like hanging portion formed in a spiral shape on the outer periphery of the rack body 16 (the inner circumferential cross section is not particularly limited to a circular shape, an elliptical shape, a polygonal shape, etc.) May be provided. In this case, the rail-like hanging portion is preferably formed in a lattice shape or a stitch shape so that the yarn can be sufficiently immersed in the plating solution.

  The fiber plating jig according to the present invention, and the fiber plating method using the same, can reduce the installation area of the fiber plating facility and realize an efficient plating process. It becomes possible and is extremely beneficial to the industry.
