Description

The present invention relates to a method for producing a double structure pleated fabric using natural fibers.

Conventionally, as a method of forming pleats (wrinkles) on a fabric, a mechanical pressure is used in the final processing stage to obtain pleats, or a fabric is constituted by a strong twisted yarn, and an untwisting torque is applied to the strong twisted yarn. There is a crepe method to generate. However, when pleats are obtained by a method using mechanical pressure, the durability of the pleats is lacking, and in particular, there is a drawback that the pleats easily disappear during wearing or washing. Further, the chirimen method has a drawback that it is limited to fabrics made of strong twisted yarns that generate untwisting torque.

For this reason, by applying mechanical pressure to the fibrillated type composite fiber fabric made of polyamide and polyester to cause necking, the fabric is then opened into fibrils, and then heat-set at 170 to 190 ° C. A method for producing a fabric having a durable surface pleating effect (Patent Document 1) has also been proposed.

However, since this method uses synthetic fibers, natural fibers such as silk cannot be used, and mechanical pressure is applied to cause loosening, so that there is a problem that pleats disappear during washing. Furthermore, these fabrics have a single weave and have poor heat retention, and it is difficult to adjust the pleat interval.

The present invention improves the above problems, improves the heat retention as a double woven structure, does not lose pleats during washing, and can easily adjust the pleat interval, and a method for producing the same Is to provide.

The double structure pleated fabric according to claim 1 of the present invention is a double woven structure using natural fibers on one side fabric and the other side fabric, and heat shrinkable fibers as wefts along the warp direction on one side fabric. The fabric on one side and the fabric on the other side are woven in a single direction in the warp direction at a predetermined interval along the weft direction, and the fabric on the other side along the warp direction. Long and large pleats are formed, and short fine pleats along the warp direction are formed on one side of the fabric.

The double-structured pleated fabric according to claim 2 of the present invention, wherein the natural fiber is silk, cotton, hemp or wool. The double-structure pleated fabric according to claim 3, wherein the heat-shrinkable fiber is a polyurethane fiber.

According to a fourth aspect of the present invention, there is provided a method for producing a double-structured pleated fabric, wherein a warp and a weft are double-woven using natural fibers, and a heat shrinkable fiber is used as a weft on one side of the fabric in a predetermined direction along the warp direction While weaving at intervals, the fabric on one side and the fabric on the other side at a predetermined interval along the weft direction, single weaving in the warp direction and closing together, then immersing this double woven fabric in hot water, The heat-shrinkable fibers woven into one side fabric are shrunk to form a plurality of long and large pleats continuous along the warp direction on the other side fabric, and from the pleats along the warp direction to one side fabric. A plurality of fine pleats having a short interval are formed.

According to the double structure pleated fabric according to claim 1 of the present invention, short fine pleats are formed on one fabric, and long and large pleats are continuously formed on the other fabric, forming a bag shape as a whole. Therefore, the amount of air retained is extremely large, and when used as a muffler or clothes, the heat retaining effect is extremely high. Further, since natural fibers are used as the fibers, the heat retention effect can be further improved. Moreover, since the pleats are not formed by applying mechanical pressure as in the prior art, the pleated shape can be maintained semipermanently.

Moreover, according to the double structure pleated fabric of Claim 2, silk, cotton, hemp, or wool can be used as natural fiber, and heat retention can be improved.

According to the double-structure pleated fabric of claim 3, when the heat-shrinkable fiber is a polyurethane fiber, the pleat can be easily formed by shrinking with hot water and also retains stretchability after shrinkage. can do.

According to the method for manufacturing a double-structure pleated fabric according to claim 4, the pleat shape can be easily formed, and the size of the pleat can be reduced by changing the interval between the single woven portions and the weaving interval of the heat-shrinkable fibers. Can be adjusted.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows a double structure pleated fabric according to the present invention, which has a double woven structure of a fabric 1 on the back side on one side and a fabric 2 on the front side on the other side. A long and large pleat 6 </ b> A is formed along the back side, and a short fine pleat 6 </ b> B is formed along the direction of the warp 3 on the fabric 1 on the back side.

As shown in FIG. 3, the method for manufacturing this double-structure pleated fabric is made by shifting up and down the heel frame through the odd-numbered warps 3 of, for example, 1, 3, 5, 7... Forming the fabric 2 on the front side. , And the heel frame through which the even-numbered warps 3 of 2, 4, 6, 8,...

In this state, the front side fabric 2 is woven by passing the weft yarns 4A forming the front side fabric 2 between the odd-numbered warps 3 of 1, 3, 5, 7. Similarly, the weft 4B forming the fabric 2 of the back fabric 1 is passed between the even-numbered warps 3 of 2, 4, 6, 8...

Next, as shown in FIG. 4, for example, odd-numbered warps 3 of 1, 3, 5, 7,... Are arranged upside down and the warps 3 of 21 and 23 are arranged below the weave of the fabric 1 on the back side. The even number 2, 4, 6, 8,. In addition, the lower 2, 4, 6, 8,... Even-numbered warps 3 are arranged upside down and the warps 3 of 22 and 24 are placed on the upper 1, 3, 5, 7 of the upper fabric 2. Raise to the position of warp 3 and reverse this part up and down.

In this state, the front side fabric 2 is woven by passing the weft yarns 4A forming the front side fabric 2 between the warps 3 of 1, 3, 5, 7,. Similarly, the back side fabric 1 is woven by passing the weft yarns 4B forming the back side fabric 2 between the warp yarns 3 of 2, 4, 6, 8,...

In this way, the warp 3 of 21 and 23 and the warp 3 of 22 and 24 are turned upside down so that the fabric 1 on the back side and the fabric 2 on the front side are separated by a predetermined distance along the direction of the wefts 4A and 4B (for example, 2 to 2). 5 cm), a single weaving portion 9 is formed by single weaving in the warp 3 direction and closing together.

Next, as shown in FIG. 5, odd-numbered warps 3 of 1, 3, 5, 7,... Are arranged upside down, and warps 3 of 21 and 23 are returned upward, during which the front fabric 2 The weft 4A forming the thread is passed. Similarly, the even-numbered warps 3 of the lower 2, 4, 6, 8,... Are shifted up and down, the warps 3 of 22 and 24 are lowered, and the weft 4B forming the fabric 1 on the back side is passed between them.

In this way, the single weave portions 8 are sequentially formed along the direction of the warp 3 at predetermined intervals along the direction of the wefts 4A and 4B while moving the warp 3 up and down. After weaving a predetermined length, weft 4A is passed between odd-numbered warps 3 of 1, 3, 5, 7 ... as shown in FIG. 7, and even-numbered warps of 2, 4, 6, 8 ... below After passing the heat-shrinkable fiber 9 such as polyester between the three, the yarn is double-woven through the wefts 4A and 4B while moving the warp 3 up and down with a heel frame as described above.

As a result, as shown in FIG. 7, the single weaving portion 8 is double-woven while being formed at intervals along the warp direction, and at the same time, the heat-shrinkable fibers 9 are arranged at a predetermined interval along the warp direction (for example, 1 ˜5 cm) to produce a double woven fabric 10.

Next, when the woven double woven fabric 10 is immersed in hot water at 80 to 100 ° C. to shrink the heat-shrinkable fibers 9, two fabrics 1 on the back side and fabric 2 on the front side are obtained as shown in FIG. As shown in FIG. 2, heat-shrinkable fibers 9 are woven as wefts at a predetermined interval along the warp direction as shown in FIG. 2, and the back side fabric 1 and the front side fabric 2 are formed. Are formed at predetermined intervals in the warp direction, the front fabric 2 is formed with a long and large pleat 6A along the direction of the warp 3, and the back fabric 1 is provided with the warp 3 Short and fine pleats 6B are formed along the direction.

As shown in FIG. 1, the double-structure pleated fabric thus formed is formed into a bag shape as a whole by the front side pleat 6A and the back side pleat 6B. In particular, the fabric 1 on the back side contracts the single woven portion 8 and the portion surrounded by the square with the heat-shrinkable fibers 9, so that a short and fine pleat 6B is formed.

As a result, the double structure pleated fabric of the present invention has an extremely large amount of air retention, and when used as a muffler, has a very high heat retention effect. Moreover, since natural fibers, such as silk, are used as a fiber, a heat retention effect can be improved further. Further, since the pleats are not formed by mechanically applying pressure as in the prior art, the pleats are not lost during repeated washing, and the pleated shape can be maintained semipermanently. The size of the pleats 6A and 6B can be adjusted by changing the interval between the single woven portions 8 and the weaving interval of the heat-shrinkable fibers 9.

In the above description, the case where silk is used as the natural fiber has been described. However, cotton, hemp, or wool may be used. The heat-shrinkable fibers are not limited to polyurethane fibers, but other fibers may be used. Polyurethane fibers can easily form pleats by immersing in hot water and retain elasticity after shrinkage. This is most preferable. In the above description, the long side pleat 6A is formed on the front side fabric 2, and the short side fine pleat 6B is formed on the back side fabric 1, but the reverse is also possible.
