Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a twisted yarn used as a yarn for knitting, woven fabric, or decoration, and a method for producing the same.

(Prior Art) A conventional twisted yarn is formed by twisting a long and narrow ordinary paper all over, and its appearance is twisted and monotonous. Then, a plurality of such twisted yarns are combined by intertwisting or the like to give a unique appearance.

In addition, in the conventional manufacturing method, a long and narrow ordinary paper is twisted over the whole to make a twisted yarn, and the only way to give peculiar appearance is to twist twisted yarns with a monotonous appearance It was

(Problems to be Solved by the Invention) As described above, the conventional twisted yarns have a unique appearance by combining a plurality of twisted yarns, and no twisted yarn alone has a unique appearance. Therefore, it is not used alone for decoration,
Its applications were mainly limited to knitting and textiles.

Further, since the conventional manufacturing method twists the whole, only a twisted yarn having a monotonous appearance with almost no unevenness can be produced. Moreover, since a thin and monotonous paper is used as the material for the twisted yarn, it is difficult to determine the twisting position.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, in the first invention, a stretchable fiber and a non-stretchable fiber are mixed and formed, and the stretchable fiber is in a stretched state. The easy-twisted part of the tape body and the easy-twisted part of the unstretched part are alternately twisted to form the twisted part, while the difficult-twisted part is used as the difficult-twisted part. The gist is that the twisted portions and the difficult twisted portions are formed alternately and continuously.

Further, in the second invention, the extensible fibers and the non-extensible fibers are mixed, and the easy-twisted portion in the stretched state and the difficult-twisted portion in the unstretched state of the stretchable fibers are alternately continuous. While each easy-twisted part of the tape body is mainly twisted to form a twisted part, the difficult-twisted part is formed into a flat plate shape that is not twisted to form a difficult-twisted part, and the same-twisted part and the difficult-twisted part are alternately continuous. The main point is that it was formed.

Further, in the third invention, a base paper tape is formed by slitting a base paper formed by mixing extensible fibers and non-extendable fibers, and the base paper tape is partially stretched in the lengthwise direction to form a plurality of parts. By leaving the extensible fiber in the stretched state, the easily twisted portion made of the stretchable fiber in the stretched state and the difficult twisted portion made of the extensible fiber and the non-stretchable fiber in the unstretched state are alternately continuous. It is characterized in that a tape body is formed and that the easy twisting portion is mainly twisted.

(Operation) In the twisted yarn of the first invention, the easily twisted portion having high twistability of the tape body is twisted to be a thin twisted portion, and the difficult twisted portion having low twistability of the tape body becomes thick. Therefore, as a whole, the yarn has a unique appearance in which the thin twisted portion and the thick twisted portion are continuously connected.

According to the second invention, the easily twisted portion having high twistability of the tape body is twisted to be a thin twisted portion, and the difficult twisted portion having low twistability of the tape body is formed in a flat plate shape. As a result, the thin twisted portion and the flat plate-like difficult twisted portion are continuously connected as a whole, and the yarn has a peculiar appearance.

According to the method of the third invention, the extensible fiber is stretched at the portion where the base paper tape is pulled, while the non-stretchable fiber is cut or broken by slipping or loosening of the fibers. The tape body thus formed is composed of extensible fibers over the entire length and non-extensible fibers intermittently and inseparably mixed with the extensible fibers. In other words, the tape body consists of an easy-twisting part having high twistability, which consists of durable and flexible stretchable fibers in a stretched state, and stretchable fibers in a non-stretched state and non-stretchable fibers that form the appearance of a twisted yarn. It has two patterns, namely, a difficult twist portion having low twistability.

When the easily twisted portion of the tape body is mainly ignited, the twisted yarn has a shape in which the thin twisted portion and the thick difficult twisted portion are continuously connected.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

First, a twisted yarn 1 which is an embodiment of the first invention will be described with reference to FIGS.

In this embodiment, as the extensible fiber, a thermoplastic fiber 2 having a length of about 10 mm (trade name "polyester fiber for paper making (low softening point type) TMO7N-1.1D × 10" manufactured by Teijin Ltd.) and a non-extensible fiber are used. Manila hemp fiber 3, which is a short fiber having a length of about 3 to 4 mm, is used. These fibers are mixed at a ratio of 7: 3 by a cylinder paper machine (not shown) and then dried at about 100 ° C. to obtain a base paper. The fiber direction of both fibers 2.3 is the same as the rotation direction of the cylinder cylinder of the cylinder machine. This base paper is slit in the fiber direction of both fibers with a width of 10 mm to make a base paper tape 4, and the same base paper tape 4 is pulled in places in its length direction. At this time, the thermoplastic fiber 2 is stretched at each pulled position, while the Manila hemp fiber 3 is cut, or the fibers are broken or loosened to be separated. A highly twistable, easily twisted portion 5 made of the thermoplastic fiber 2 which is stretched in such a manner as to be flexible and strong, and a low twistable twist which is made of the thermoplastic fiber 2 and the Manila hemp fiber 3 which are not stretched A tape body 7 having two patterns with the portion 6 is formed.

Then, the tape body 7 configured as described above is used for 300 to 500
When twisted while applying a tension of g, the easily twisted portion 5 is twisted more and this is made into the twisted portion 1a, while the difficult twisted portion 6
Is loosely twisted and rounded to form the difficult-to-twist portion 1b. In this way, the difficult-to-twist portion 1b is rounded and formed thicker than the twisted portion 1a, and the entire twisted yarn 1 has a thin twisted portion 1a and a thick difficult-twisted portion 1b.
The shape is such that and are continuously connected.

From the above, the twisted yarn of this example has the following effects.

(A) Twisted yarn 1 has a peculiar appearance as a single unit, and can be used alone for decorative purposes. Furthermore, when twisted in combination with a plurality of ordinary yarns or paper tape, High design effect can be expected.

(B) The thermoplastic fiber 2 and the Manila hemp fiber 3 are well disintegrated and mixed, and the fiber direction is so mixed in the rotation direction of the cylinder cylinder that it is difficult to separate into both fibers 2 and 3. Since the thermoplastic fiber 2 passes through the entire length of the twisted yarn 1, it is durable against pulling in the length direction. The fiber directions of both fibers 2 and 3 are preferably in the rotational direction of the gauze cylinder, but the fiber directions may differ depending on the shape of the application.

(C) Since the thermoplastic fiber 2 of the easily twisted portion 5 is stretched to be rough and flexible, the easily twisted portion 5 has high twistability, and the twisted portion 1a can be twisted finely.

(D) Since the entire twisted yarn 1 is composed of fibers having different thicknesses and thicknesses, when the same twisted yarn 1 is used by knitting, it is possible to obtain a processed product having excellent breathability and the like.

(E) Since the twisted yarn 1 is composed of the tape body 7 having two patterns of the easily twisted portion 5 and the difficult twisted portion 6 having different compositions,
When dyed, the twisted yarn 1 is made up of two patterns having different colors depending on the portions 5 and 6, and different in color condition. Furthermore, the appearance is unique and the design effect is enhanced. For example, when Kayastein Q manufactured by Nippon Kayaku Co., Ltd. is used as a dye, the thermoplastic fiber 2 becomes blue and the Manila hemp fiber 3 becomes yellow. The dyeing may be performed at any time after the base paper is made, the base paper tape 4 is stretched, and twisted.

(F) In addition, without making the lengths of all the difficult twisted portions 1b uniform,
For example, twisting yarns having different tastes can be obtained by forming alternate long yarns or short yarns or crushing the difficult twisted portion 1b to flatten it.

Next, the second invention will be described.

The twisted yarn of one embodiment of the second invention shown in FIG. 3 is the tape body 7 in which the difficult-twisted portion 6 is formed in a flat plate shape in the embodiment of the first invention, and the thin twisted portion 1a is wide as a whole. The shape is such that the difficult-twisted portion 1b having a flat portion is continuously connected. The twisted yarn of this embodiment is manufactured by twisting a tape body 7 in which the difficult-to-twist portion 6 is thickly formed. In addition, according to this embodiment, in addition to the effect of the twisted yarn of the first embodiment of the present invention, for example, another flat twisted portion 1b may be coated with another paper and used for decorative purposes. Further, when the dyeing is performed in the same manner as in the embodiment of the first invention or when the alternate difficult twisted portions 1b are formed into long ones and short ones as shown in FIG. 4, the appearance becomes more peculiar and the design effect is enhanced.

Next, a first embodiment of the third invention will be described with reference to FIG. 1 and FIGS. First, as an extensible fiber, a thermoplastic fiber 2 having a length of about 10 mm (made by Teijin Ltd., “Polyester fiber for papermaking (low softening point type) TMO7N-1.1D × 1”)
0 ") and Manila hemp fiber 3 having a length of about 3 to 4 mm as a short fiber are mixed in a ratio of 7: 3 by a net paper machine (not shown), and then dried by a dryer at about 100 ° C. to obtain a base paper. In addition,
The fiber direction of both fibers 2.3 would be the direction of rotation of the cylinder cylinder of the cylinder machine. Further, the base paper is slit into a width of about 10 mm along the longitudinal direction of the fiber and the base paper tape 4
make.

Next, a method for stretching the base paper tape 4 in places will be described with reference to FIGS.

First, in the apparatus used in this embodiment, a gear 8 that is a rotating body, a toothed belt 9 that meshes with and interlocks with the gear 8, a pressing belt 10 that presses the toothed belt 9, and a base paper tape 4 A holding portion (not shown) for applying tension is provided. The gear 8 and the toothed belt 9 are alternately formed with tooth portions 11 as convex members and trough portions 12 as concave members, respectively. The gear 8 is rotated in the counterclockwise direction in FIG. 8 by a drive source (not shown), and the toothed belt 9 is also meshed with the gear 8 and sent to the left side in FIG. Further, the pressing belt 10 contacts the outer surface 9a of the toothed belt 9 at the meshing portion 8a of the gear 8 and the toothed belt 9, and rotates while pressing the toothed belt 9.

The base paper tape 4 is held at its end portion by a holding portion (not shown) and pulled in the direction opposite to the retracted direction which is the lower side of FIG. The tape 8 is stretched by the toothed belt 9 and the toothed belt 9 to be processed into the tape body 7, which is then sent to the left side in the drawing and wound up by a tape body winding reel (not shown). At this time,
As shown in FIG. 9, the base paper tape 4 includes a gear 8 and a toothed belt 9
And the front edge 11a of the toothed belt 9 between the toothed portion 11 of the gear 8 and the rotational direction of the toothed portion 11 of the gear 8 and the front side of the toothed belt 9 in the moving direction. The thermoplastic fiber 2 is stretched by the edge portion 11b of the fiber and the Manila hemp fiber 3 is cut, or the fibers are cut off or loosened to be separated. That is, the base paper tape 4 is one of the gears 8.
One portion of the pitch L4 is pulled by a length corresponding to the engagement depth length L3, and the thermoplastic fiber 2 is stretched at the central portion thereof. Thus, as shown in FIGS. 5 to 7, a twistable portion 5 having a high twisting property made of the thermoplastic fiber 2 in the stretched state, a twisted fiber made of the thermoplastic fiber 2 in the unstretched state and the Manila hemp fiber 3 are twisted. A tape body 7 having a poorly twisted portion 6 and two patterns is formed. The length L1 of the easily twisted portion 5 of the tape body 7 is determined by the engagement depth L3 (see FIG. 9) of the tooth portion 11 and the valley portion 12, and the length L2 of the difficult twist portion 6 is Determined by the pitch L4 between the gear 8 and the toothed belt 9,
The length of L1 and L2 is the length of the inner circumference of the belt, and in the present embodiment, the length L1 of the easily twisted portion 5 is 2 to 3 mm.
After this, while the tape body 7 configured as described above is wound on the tape body take-up reel, the rear end portion of the tape body 7 is pulled out and rotated while applying a tension of 300 to 500 g to form the easily twisted portion 5 Is twisted to form the twisted portion 1a, while the difficult twisted portion 6 is not twisted so much to become the difficult twisted portion 1b, and thus the twisted yarn is formed. Therefore, the twisted portion 1b
Is formed thicker than the twisted portion 1a, and the entire twisted yarn 1 has a shape in which the thin twisted portion 1a and the thick difficult twisted portion 1b are continuously connected.

Next, the effect of the manufacturing method of this embodiment will be described.

(A) Desirable elongation because thermoplastic fiber 2 (polyester fiber for paper making (low softening point type) TMO7N-1.1D × 10) manufactured by Teijin Ltd., which is a polyester fiber having a length of about 10 mm, is used as the extensible fiber. And the strength is obtained.

(B) Since the Manila hemp fiber 3 having a length of about 3 to 4 mm is used, the boundary portion between the two patterns of the tape body 7 can be sharply formed.

(C) These thermoplastic fibers 2 and Manila hemp fibers 3 are well disintegrated and mixed, and the fiber directions are so mixed in the direction of rotation of the cylinder cylinder that they cannot be separated. Can be processed. Furthermore, since both fibers 2 and 3 having such a length are mixed in a ratio of 7: 3, desirable elongation and tensile strength can be obtained. Both fibers 2, 3
The fiber direction is preferably the same as the rotation direction of the cylinder cylinder, but the fiber direction may be different depending on the shape of the application. In addition, it can be manufactured with a short-net or long-net paper machine having different shapes.

(D) Since the drying temperature in the dryer after papermaking is set to 100 ° C., the thermoplastic fiber 2 has desired toughness, strength, and adhesiveness of the Manila hemp fiber 3.

(E) Since the width of the tape body 7 is set to about 10 mm, the strength of the entire twisted yarn is sufficient, and the difficult-to-twist portion 1b can be thickened to enhance the design effect.

(F) Since the length L1 of the easily twistable portion 5 is set to 2 to 3 mm, the design effect can be enhanced without impairing the strength of the entire twisted yarn. Also,
Since the thermoplastic fiber 2 of the easily twisted portion 5 is stretched to be rough and flexible, the easily twisted portion 5 has a high twisting property, and the twisted portion 1a can be finely twisted.

(G) When the tape body 7 is made, the difference in properties such as the length and elongation of both fibers 2 and 3 is used, so that the tape having two patterns can be easily formed by only partially pulling the base paper tape 4. The body 7 can be formed.

(H) Since the gear 8 and the toothed belt 9 which are rotating bodies are used, the base paper tape 4 is continuously and partially extended, and the efficiency is 2
It is possible to form a tape body 7 having two patterns,
Furthermore, since the base paper tape 4 is held by the toothed belt 9,
Accurate processing can be performed without causing distortion or the like.

(I) When processing the base paper tape 4 into the tape body 7,
Since tension is applied to the base paper tape 4, the base paper tape 4
Can be reliably extended.

(E) The length L1 of the easily twisted portion 5 is set by the engagement depth L3 between the tooth portion 11 and the trough portion 12 of the gear 8 and the toothed belt 9 and the tension applied to the tape body 7, or Since the length L2 can be easily changed by changing the pitch L4 of the gear 8 and the toothed belt 9, twisted yarns having various shapes can be easily produced.

(L) That is, according to the manufacturing method of the present embodiment, the easy-twisted portion 5 that is easy to twist and strong can be formed easily, reliably, and at a relatively free position. As a result, it is possible to provide an excellent twisted yarn which has a peculiar appearance as described above and can sufficiently withstand practical use in strength and the like. Further, as shown in the embodiment of the first invention, a higher design effect can be obtained by dyeing.

When manufacturing the tape body 7, in addition to slitting the base paper thinly as in the present embodiment and then pulling, the base paper may be first slit widely and then stretched and stretched, and then it may be slit thinly.

In this case, the base paper tape 4 is stretched mainly near the center of the lower surface of the protrusion 38. Alternatively, instead of the fixing member 37, tension may be applied to the base paper tape 4 when the extending distance is short. Further, the female mold 35 and the male mold 36 may be embossed in a continuous manner.

Next, a fourth embodiment of the third invention will be described.

This embodiment also differs from the first, second and third embodiments only in that the base paper tape 4 is stretched to form the tape body 7.
