Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a permanent crease formation method and a fluid injector used therein.

GB 147285'2 patent discloses a method for forming permanent folds in textiles.

According to this method, temporary folds are formed in the textile product,
A liquid adhesive, which converts to a solid insoluble in water and dry cleaning solvents, is then placed in a rotary syringe, and the syringe is guided along the first fold to fold it before final hot pressing. It is designed to form a line of liquid adhesive within the vertex of the eye.

This process either produces stable creases that last for a long time during dry cleaning, or creases are not sufficiently formed under certain conditions of moisture and the action of external physical forces.

Furthermore, although a pre-pressure process and a final pressure process are required, a steam pressure process must be added for this purpose, so it is not necessarily suitable for the clothing manufacturing process.

By using certain injection formulations, the present invention allows the final hot pressing step to be eliminated without adversely affecting the quality and permanence of the fold, preferably when used with a non-rotating injector. , a method for forming permanent folds in textiles and the fluids used therein, with which process steps can be omitted and furthermore the permanence of the folds, especially under conditions of moisture and mechanical action, can be improved. The purpose is to provide a syringe.

The method of the present invention includes the steps of imparting a predetermined sharp temporary crease to a textile product, a rotating member engaging a surface of the textile product, and pushing a curable formulation from a reservoir in response to rotation of the rotating member. dispensing the curable composition by forcing the curable formulation from the tip of the syringe toward the apex of the temporary fold by moving a fluid syringe comprising a dispensing device along the temporary fold; This is achieved by a method for forming permanent folds in textile products, characterized in that a permanent fold is formed on the textile product when the curable resin is solidified.

Thus, as used herein, "response" means that an amount of curable compound is extruded that is responsive or proportional to the angle of rotation of the rotating member.

The formulation injected into the folds is preferably a curable formulation of natural or man-made materials that is insoluble in water or dry cleaning solvents.

The amount of compound used is preferably 1/4 to 2 mm.
It is advantageous that a depth of approximately 1 mm is sufficient to fill the apex of the fold.

If the amount is greater than this, creases similar to the sewn-in creases used in the dark will be formed on chassis pants, and if the amount is less than this, the "injection" effect will be insufficient.

The formulation may be a curable latex or a curable thiocol, polyurethane or silicone rubber, preferably the latter.

The silicone formulations preferably injected in the steps of the method according to the invention are soft, pliable, insoluble rubbery materials.

Such formulations are commercially available as formulations for many end uses such as caulking.

A particularly useful formulation has the trade name S 1lastic RTV.
(Dow Corning) 5ilcose
It sells for 151.152.153 (ICI).

The curing action of this formulation is brought about by its chemical crosslinking nature and is therefore irreversible.

Preferably, the curing action occurs at room temperature and during the curing period the textile is folded flat along the crease line.

The amount of injection formulation to be used is as per Prior Patent No. 14728.
Although the amount of adhesive used in the process steps according to No. 52 is higher, the properties of this formulation make it possible to form durable and aesthetically pleasing folds without a final pressing step.

The prior patents disclose various types of rotary injectors.

That is, when applying the injection compound to the folds, a rotating body is provided at the tip of the syringe, and the injection compound is applied to the folds by moving the rotating body along the folds of the textile product.

However, this method is not necessarily suitable for sufficiently injecting the compound into the apex of the fold.

The fluid injector used to apply a curable formulation to the folds of a textile product of the present invention to form a permanent fold comprises a reservoir, a nozzle connected to the reservoir,
The invention is characterized in that it includes a rotating member that is engageable with the surface of the textile product and a device that forces fluid from the reservoir through the nozzle in response to rotation of the rotating member.

That is, in the syringe disclosed in the prior patent specification, the compound is drawn out from the reservoir and applied to the crease while the rotating body rotates, whereas in the syringe of the present invention, a nozzle is provided at the tip of the reservoir, and the rotating body rotates. The rotating member is configured to rotate by contacting the member onto the textile and moving the syringe along the fold to expel the formulation in the reservoir toward the nozzle in response to rotation of the rotating member. ing.

Since the injector of the present invention is constructed in this manner, it is possible to reliably and uniformly apply a predetermined amount of the compound to the folds of the textile product.

The nozzle has an elongated hole at its tip, and the injector of the present invention is moved along the fold so that the longitudinal direction of the elongated hole crosses the axis of the rotating shaft of the rotating member. Preferably, the hole is connected to the reservoir in such a way that the longitudinal direction of the hole is substantially parallel to the fold.

The rotating member may be of any type as long as it allows the syringe to move smoothly over the textile product.

However, if the rotating member has a pulley-like shape, that is, it has two disc-shaped rotating plates of the same diameter concentrically and spaced apart, the rotating member can engage the textile product on both sides of the fold. The nozzle can be guided along the apex of the crease.

The rotational speed of the rotating member determines the rate of fluid exit from the nozzle.

However, the amount of formulation injected into the fold (ie, the amount of formulation applied per unit length of the fold) is not affected by the rotational speed of the rotating member, ie, the rate of movement of the fluid injector.

Preferably, the reservoir is a replaceable passenger container.

For example, it is convenient to use a hypodermic syringe body that is molded in one piece using plastic material.

Such syringe bodies are commercially available and therefore extremely inexpensive.

In this case, the nozzle portion at the tip of the syringe body may be used as the nozzle of the fluid injector of the present invention, or the nozzle of the fluid injector of the present invention may be fitted into the nozzle of the syringe body.

A device for pushing out fluid consists of a piston inserted into a reservoir and a device for moving the piston through the reservoir in conjunction with the rotation of a rotating member.

The device for moving the piston in the reservoir in response to rotation of the rotating member may be a worm gear device provided between the rotating member and the piston.

It is also possible to provide an auxiliary device that allows the piston to move on its axis.

This auxiliary device serves two roles:

That is, its first role is that when the application of the cured compound to the folds of the textile product is finished, the cured compound in the reservoir expands due to the temperature present in the reservoir and leaks from the nozzle. It plays a role in preventing this.

That is, in this case, the piston may be moved back a little using the auxiliary device.

Another role is to provide an initial pressure in the reservoir at the beginning of the injection process.

That is, in this case, the piston may be moved forward a little using the auxiliary device.

The fluid injector according to the present invention is the most effective device when carrying out the method according to the present invention, and can be widely used in cases where continuous injection of fluid of a constant density is required. can.

When carrying out the method and device according to the invention, it is advantageous to provide a guide plate for textile products.

The surface of the guide plate is provided with grooves shaped to receive the folds of the pre-folded textile product, and the folds of the textile product are placed in the grooves and the compound is applied. This allows the formulation to be injected correctly at the top of the crease.

Textile products to be permanently creased may also be made in the shape of clothing, such as pleated skirts or trousers.

Clothing may be made of one type of fiber or a mixture of fibers, natural or synthetic, but the method according to the invention must in principle be applicable to natural fibers that do not have heat-set properties, such as cellulose, keratin fibers, and in particular wool.

The form of the cloth may be woven or knitted, ie, non-woven.

The present invention is particularly useful for garments, such as knits, for which it has heretofore been difficult to form permanent creases.

By performing the crease forming method of the present invention using the fluid injector of the present invention, permanent creases can be formed.

Since the curable compound is applied from the reservoir to the apex of the fold in response to the rotation of the rotating member, it is possible to reliably and uniformly apply a predetermined amount of the curable compound to the fold of the textile product.

Furthermore, since a curable compound is used as the compound, no heat treatment step is required, which is advantageous in terms of processing time and cost.

As a result, permanent folds can be imparted to the textile product.

Furthermore, the fluid injector of the present invention has a simple structure and can be manufactured at low cost since a commercially available syringe body can be used as a reservoir.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Reservoir 11 of fluid injector 10 has a nozzle 12 in the form of a molded plastic hypodermic syringe body.

The nozzle 12 has a threaded, fishmonger shaped nozzle end 14.
is screwed in.

As can be seen in FIG. 2, the nozzle end 14 is flat and has an elongated outlet so that the contents of the reservoir 11 can be discharged.

If the reservoir 11 has a different shape, for example, a shape with a nozzle at the end in the axial direction, such as the body of a general hypodermic syringe, the contour of the nozzle 12, particularly its overall length and inclination, may be modified in accordance with the shape. .

The reservoir 11 is a base, i.e. block 16.1 described below.
8 may be connected to a rotating member or the like.

The reservoir 11 is pressed or screwed into a shaped plastic block 16.

The block 16 can be adapted to the shape of the reservoir 11.

The second block 18 made of plastic is similar to the first block 16.
It fits slidingly into a cylindrical recess formed therein and is biased outwardly by a compression spring 20.

A metal cover 22 is pivotally attached to the first block 16 by pins 24.

The cover 22 extends from the second flock 18 and
The second block 18 is held in place by a catch 26 extending into the second recessed portion 28.

The recess 28 has a certain shape, and this shape allows the catch 2
6 abuts on the adjacent inclined surface 32 and the second block 18 is pushed further into the recess of the first block 16. If the cover 22 does not pivot downwardly, the catch 26 will move into the recessed portion of the cover 22. 28, so that it is normally located at the lowest corner.

A recess 34 is formed in the second flock 18, and the recess 34 is formed in the second flock 18.
4 carries a gear wheel 36 which is internally threaded and externally toothed.

Threaded rod 38 engages internal threads of gear wheel 36, while gear wheel 36 engages externally to worm transmission 40.

The worm transmission 40 forms a rotating member 4201, said rotating member 42 having two flanges 46 on the outside and two rubber surfaces 48 on the inside.

Therefore, when the rotating member 42 is rotated, the gear wheel 36 rotates relative to the second block 18, and the rod 38 is moved in the axial direction.

Inside the reservoir 11, at the distal end of the rod 38, a sealing member 50 is carried on a profile 52, which fits slidably and firmly against the reservoir 10.

The sealing member 50 transfers the contents of the reservoir 11 to the nozzle 12.
It is designed to be pushed towards.

When using the fluid injector 10, the reservoir 11 is filled with a fluid, for example a curable silicone rubber compound, and the block 16 is filled with this compound together with the twisted piston rod 38 and sealing member 50 assembly at 1 adjacent thereto. into the reservoir 10 filled with.

After engaging the rotary member 42 with the surface of the textile product to be injected with fluid, the cover 22 is pushed down to contact the second block 18 and the catch 26 is moved to the position shown in FIG.
2 and slightly compresses the fluid in the reservoir 11, thereby moving the fluid toward the orifice of the nozzle 12.

With the nozzle 12 positioned as desired, the fluid injector 10 is moved by the rotational action of the rotating member 420.

Rotation of the rotating member 42 drives the rod 38 and sealing member 50 through the reservoir 11, squeezing fluid out of the nozzle end 14 in an amount proportional to the amount of rotation of the rotating member 42.

When the fluid is on the desired line, lift the fluid injector 10 from the surface of the fabric and relieve the pressure on the cover 22.

The spring 20 actuates the second block 18 and the stopper 26 to force the stopper 26 completely against the inclined surface 32 so that the recessed portion 2
Lock it at the lowest corner of 8.

This causes the rod 38 and sealing member 50 to retract slightly and the pressure within the reservoir 11 to decrease, thereby preventing unnecessary leakage of fluid from the nozzle end 14.

As shown in FIG. 4, a knurled handle 39 may be provided at the end of the rod 38 to serve to preload the piston when a new infusate container or reservoir 11 is fitted to the operating mechanism.

By attaching the above-mentioned cover 22 and handle 39 to the fluid injector 10 as auxiliary devices, it is possible to appropriately adjust the start of discharging the curable compound and leakage prevention before and after the start of work with the fluid injector 10. can.

The fluid injector 10 of the present invention is particularly advantageous when performing the crease forming method of the present invention in conjunction with a grooved garment support and guide device specifically designed to cooperate therewith.

FIG. 5 shows the use in combination with a grooved support arm 54 supporting an inverted pant leg 56, said support arm 54 supporting a temporary fold 58 and fluid management. It engages the device 10.

The flanges 46 of the rotating member 42 fit on either side of the upper part of the support arm 54, and the rubber surfaces 48 rest on either side of the fold line 58 of the pants.

Correct orientation of the nozzle end 14 into the apex of the fold allows very precise injection of the silicone formulation into the pre-folded pants.

The pants are then removed from the support arm 54 and immediately turned inside out and leveled to allow the formulation to solidify.

Trousers treated in this manner have creases that look good and last long when worn, dry cleaned, and washed.
