Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a form-stabilized fiber product, and a fabric for apparel and a blade used as a dedicated material for the product.

[0002]

2. Description of the Related Art Textile products that require form stabilization include:
There are various types of clothes, hats, handbags, handbags, and the like.

[0003] Woven fabrics and knits (knitted fabrics) are used as materials for this fiber product, and blades (braided flat braids) are often used as materials for hats and the like. By the way, among the material fabrics such as clothes and hats, fabrics made by weaving cotton, hemp, or yarns having a higher blending ratio of such fibers are particularly wrinkled. For this reason, the woven fabric is resin-processed (wrinkle-preventing process) to make it hard to wrinkle. Resin processing is also applied to high-density blends of synthetic fibers, which are relatively hard to wrinkle, in order to provide more complete wrinkle resistance.Recently, advanced form stability for cutter shirts etc. Processing (wash and wear processing, permanent processing, etc.) is also applied.

[0004]

The method of improving wrinkle prevention by resin processing or the like involves a complicated fabric manufacturing process and has problems in productivity and cost. In addition, the form stability function by resin processing or special processing often does not last for a long time, for example, it gradually disappears due to cleaning or the like.

Although knits are less likely to wrinkle than woven fabrics, they have the disadvantage that they are easily deformed, but it is difficult to give the knits a shape-retaining function by resin processing for wrinkle prevention.

Further, in the case of a hat blade called Sanada for hats, hemp, which is the strongest among natural fibers, is often used as a material, but hats made of hemp blades are folded when folded small. Is left and the appearance deteriorates. In addition, when hemp gets wet with water, the waist becomes weak (flexible) and the product is easily deformed.

Accordingly, an object of the present invention is to provide a manufacturing method for easily producing a form-stabilized fiber product which is hardly deformed and wrinkled, and a dedicated material for the method.

[0008]

In order to solve the above problems, in the present invention, the following fabrics (1) and (2) for the apparel of the present invention are cut and sewn. A method of thermoforming at a temperature exceeding the melting point is employed. (1) Apparel fabric comprising low-melting-point yarns for weft yarns or alternate warp yarns and alternate weft yarns, and weaving the low-melting-point yarns and other yarns. (2) Fabric for apparel made by knitting low-melting-point yarns in a knitted base knit structure.

Further, a method of forming and knitting the fabric for apparel of the above (2) into a required shape and then thermoforming at a temperature exceeding the melting point of the low melting point yarn is adopted.

Further, the following (3) and (4) blades of the present invention are sewn or woven to form a blade sheet, and the sheet is thermoformed at a temperature exceeding the melting point of the low melting point yarn. (3) A blade made of flat yarn made of raw yarn with low melting point yarn contained in the constituent fibers. (4) A blade in which a low-melting yarn is contained in a raw yarn, and the low-melting yarn original yarn and the non-low-melting yarn original yarn are flat-brushed.

[0011]

The low-melting-point yarn contained in the apparel fabric and the blade of the present invention undergoes plastic deformation during thermoforming according to the manufacturing method of the present invention, and then cools and hardens to maintain the formed shape. Further, at the time of thermoforming, the low-melting-point yarn adheres to other yarns, so that the yarns are heat-fixed to each other, which also improves the shape retention. Therefore, the product is hardly wrinkled, and the shape of the product is hardly deformed.

Further, in the production method of the present invention, since a material containing a low melting point yarn is used, only the finish molding is performed by thermoforming, and the process is not complicated and the cost is not increased.

[0013]

1 to 3 show an embodiment of an apparel fabric according to the present invention. 1 and 2 are woven fabrics. These woven fabrics 1 and 2 are actually densely woven, but the drawing shows the arrangement pitch of the yarns coarse for ease of understanding.

The woven fabric 1 shown in FIG. 1 is obtained by plain weaving a warp (warp) 3 and a low-melting weft (weft) 4.

In the woven fabric 2 shown in FIG. 2, a normal warp yarn 3 and a low-melting-point warp yarn 5 are alternately arranged, and a normal weft yarn 6 and a low-melting-point weft yarn 4 are alternately arranged. Etc. are plain woven.

As the warp yarn 3 and the weft yarn 6, natural fiber (cotton, hemp, etc.), synthetic fiber (polyester, nylon, etc.), regenerated fiber (rayon, polynosic, cupra) or a blended fiber of these fibers is used.

The weft yarn 4 and the warp yarn 5 are made of a thermoplastic resin having a lower melting point than other yarns to be woven together, for example, polyvinyl chloride, vinylon, acryl, polypropylene,
A thread formed of acetate, polyurethane, or the like is used. The weft 4 and the warp 5 of the low melting point yarn may be monofilaments, but when the yarns 3 and 6 are formed of a thermoplastic resin, it is necessary to select a material resin having a lower melting point.

The woven fabric 2 of FIG. 2 needs to weave two weft yarns, that is, a normal weft yarn 6 and a low melting point weft yarn 4 alternately. Although it is troublesome, this form of yarn is the most excellent in the function of form stabilization obtained after thermoforming.

The weaving method of the woven fabric is exemplified by plain weaving, but is not limited to this plain weaving.

FIG. 3 shows a knit according to a third embodiment. This knit 7 is knitted on both sides using a normal knitting yarn 8 and a knitting yarn 9 of a low melting point (which has a lower melting point than the knitting yarn 8). It has become. Knits are originally less likely to wrinkle than woven fabrics,
It is easier to lose shape than woven fabric. However, the example knit 7
When subjected to thermoforming, the shape retention of the low-melting-point yarn 9 occurs, so that the shape is less likely to collapse and wrinkles are less likely to occur.

[0021] The form-stabilizing function can be achieved even in a knit of an auxiliary knitting yarn knitted by adding a low melting point yarn to a normal knitting yarn or a rubber knitting with a low melting point yarn or a knitting structure in which the low melting point yarn is knitted. It is hard to lose shape.

FIG. 4 shows an example of a hat made of the material of the present invention. The fabric used for this hat 10 is
A woven fabric 1 in which the surface is raised after cedar weaving of a natural fiber warp and a low-melting-point polyvinyl chloride weft,
The cloth is cut and sewn into a required shape, and further, using a molding die, heat is generated at a temperature higher than the melting point of polyvinyl chloride to prepare the hat 10. Even if this hat 10 is folded small and stored in a bag or a pocket of clothes, if it is taken out and opened to its original state, the folds disappear naturally and the appearance does not deteriorate.

The fabric of the present invention can be used for clothes, curtains,
It can also be used as a material for other textile products such as handbags.

FIG. 5 shows an embodiment of the blade. The blade 11 is formed by passing several (usually 6 to 12) raw yarns 13 into a flat drive by passing several (two in the figure) warp yarns 12 therethrough.

As shown in FIG. 6 (a), the raw yarn 13 is made by adding several low-melting yarns (here, single fibers of polyvinyl chloride) 15 to hemp fibers 14 and lightening them. As shown in FIG. 6 (b), a twisted one, a low melting point yarn 15 wound around the bundle of hemp fibers 14 or a low melting point yarn as shown in FIG. 6 (c). For example, a hemp fiber 14 was lightly twisted around the core 15 and used.

The low-melting yarn 15 may be added in such a manner that some of the raw yarns 13 to be flattened are replaced with low-melting yarn.

The fiber 14 constituting the raw yarn 13 may be a fiber having a higher melting point than the low melting point yarn 15, and is not limited to hemp.

FIG. 7 shows a circular sheet 17 formed by winding the blades 11 of FIG. 5 partially in an overlapping manner and spirally, and stitching the overlapping portions of adjacent blades (16 is a seam). I have. This circular sheet 17 is thermoformed using a molding die (not shown) at a temperature equal to or higher than the melting point of the low-melting yarn (a temperature at which other yarns do not melt or shrink), thereby completing a hat 18 as shown in FIG. .

This blade can also be used as a material for other products such as baskets, handbags and handbags. A sheet of material is made by a method of stitching and joining the blades or a method of plain weaving as shown in FIG. 9, and various form-stabilized fiber products can be made by processing the sheet.

[0030]

As described above, according to the present invention, the low melting point yarn is deformed by incorporating the low melting point yarn into the material for the apparel and the braid made of the material and thermoforming the product made of the cloth and the braid. In addition, since the product is attached to another yarn, the dimensional stability of the product can be easily increased without increasing the cost.

The product obtained by the method of the present invention is hardly wrinkled and has excellent shape recovery properties. Therefore, a hat made of a blade or the like can be folded small and stored in a bag or the like.

Further, since the low-melting-point yarn after thermoforming maintains its shape even when wet with water, a fiber product made of a cloth or a blade using water-absorbing cellulosic fibers (cotton, hemp, etc.) When the present invention is applied to the present invention, it is possible to prevent the form from being deteriorated due to water wetting, washing, and the like.
