Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides a woven fabric composed of a plurality of ear tissues, and particularly relates to a stretch woven fabric, which provides a woven fabric that does not bend or bend even under normal processing conditions.
[0002]
[Prior art]
In recent years, there are many products made of stretch fabrics that contain polyurethane elastic yarns in the wefts or warps of the fabrics, and the structure has been widely developed from heavy to thin, such as flat, twill, red, and dobby patterns. In these tissues, due to the development of stretch properties during processing, the ear part was folded and wound, causing poor troubles such as unevenness in width and excessive width of the processing process. In order to solve this problem, some ear tissue widths have been increased, and some have changed ear tissue, but the problem has not been solved.
[0003]
[Problems to be solved by the invention]
The present invention provides a stretch fabric that does not bend or bend even under normal processing conditions in order to solve the above-mentioned conventional drawbacks.
[0004]

As a result of intensive studies to examine the above problems, the present invention has been achieved.
That is, the present invention
1. A fabric having a difference between the front and back tissue points in the range of 4: 1 to 7: 1, and having a second ear tissue having a tissue point less than the difference between the tissue points of the fabric on the inner side adjacent to the ear tissue.
2. It is composed of short fibers of English style cotton counts 5 to 100 or long and short composite spun yarns containing 50% by weight or more, and the density between inches ranges from 15 to 30 in terms of cover factor.
3. Contains 1% by weight or more of polyurethane elastic yarn in the weft of the fabric or both the weft and the warp,
4). The weft of the woven fabric or both the weft and the warp contains 1% by weight or more of yarn and filament with a hot water shrinkage of 10% or more.
5. 5. The widths of the ear tissue and the adjacent ear tissue are each in the range of 5 to 20 mm. The weft of the ear tissue is in the form of a cord with 3 to 5 aligned;
It is comprised from the stretch fabric characterized by this.

DETAILED DESCRIPTION OF THE INVENTION
A fabric having a difference between the tissue points of the front and back surfaces in the range of 4: 1 to 7: 1, and having a second ear tissue having a tissue point less than the difference in tissue points of the fabric on the inner side adjacent to the ear tissue. Specifically, when the ground tissue is satin and the ear tissue is flat, the number of jumps of the tissue such as Venetian or 2/2 at the boundary between the satin and the flat is the satin and plain fabric. This is a stretch fabric that prevents the ears from being folded and wound by changing the structure in stages. In addition, the width of the second ear tissue and the adjacent ear tissue is 5 to 20 mm. Usually, the outer ear is wide (less than 20 mm) and the inner side is narrow (more than 5 mm). By providing this ear tissue, it is possible to prevent the ear fold and the ear winding of the woven fabric, particularly the stretch woven fabric.
[0006]
As the fiber material used in the present invention, short fiber materials include natural fibers such as cotton, wool and hemp, synthetic fibers such as polyester fibers and polyamide fibers, regenerated fibers such as rayon and polynosic, and the fibers of these fibers. Although the raw material selected from a mixture is used, it does not specifically limit.
[0007]
The count of the short fibers used as the warp is an English cotton count and is preferably in the range of 5 to 100. A thick count of 5th or less is not preferable because it is too thick. A fine article of 100 or more is not preferable because it becomes too thin and the fabric strength becomes low. The same applies when a filament is used as the warp. The fineness is preferably 1100 (thick count) to 55 (thin count) dtex.
[0008]
If the cover factor is 15 or less, too much stretch is likely to occur, and slipping easily occurs.
The cover factor was calculated by the following formula.
K = N _w × D _w ^0.5 + N _F × D _F ^0.5
(However, N _{w is the} warp density (main / 吋), D _{w is the} warp fineness (count), N _{F is the} weft density (main / 吋), and D _{F is the} weft fineness (count).)
[0009]
The weft yarn may be a spun yarn including a polyurethane elastic yarn, a twisted yarn, a twisted yarn, or a filament twisted / twisted yarn. Further, a covering yarn covered with a filament using a polyurethane elastic yarn as a core yarn may be used. In this case, the weight of the polyurethane elastic yarn is 1% by weight or more, preferably 3 to 8% by weight. If it is 1% by weight or less, the stretchability is not obtained and the stretchability is poor.
[0010]
When a yarn / filament having a high shrinkage rate is used as the weft, the shrinkage rate is 10% or more, preferably 15 to 25%. If it is 10% or less, the stretchability is poor, and if it is 30% or more, the eyes are clogged too much and the texture becomes hard. As the yarn / filament having a high shrinkage rate, a high-shrinkage span, filament, or yarn made of nylon is used, but the yarn / filament is not particularly limited.
[0011]
The width of the ear tissue is preferably in the range of 5 to 20 mm for one tissue. Ear winding cannot be prevented at 5 mm or less. If it is 20 mm or more, the cloth loss is large, which is not preferable. These ear tissues may have more than two adjacent tissues. The structure of the ear structure is not particularly limited, such as flat, twill, satin, dobby, etc., but it is preferable that the weft is aligned in a so-called oblique structure with 3 to 5 cords. When the number is less than 3, the effect of suppressing the ear winding / breaking is small, and when the number is more than 5, the balance between the front and back of the ear part is lost, which is not preferable.
[0012]
When the difference between the front and back tissue points is less than 4: 1, troubles such as ear-wrapping are unlikely to occur.
[0013]
Example: A woven fabric consisting of 3% polyurethane mixed with an English cotton count No. 60 for warp, and a cotton core yarn No. 40 having a spandex core as the No. 40 for the weft, with a texture point of 4: 1 When weaving a satin fabric with a density of 200 × 140 / inch consisting of: 25.8 weft: 22.1, weaving the ear tissue on the inside of the traditional angled ear, 3/2 separate tissue 10mm wide Formed. (Refer to FIGS. 1 to 3) When this fabric was processed under the conventional processing conditions, a processed cloth excellent in process passability and width stability was obtained without the occurrence of ear folding or ear winding.
[0014]
Comparative Example 1
This is a woven fabric consisting of 3% polyurethane mixed with an English cotton number 60 for warp and cotton core yarn No. 40 for weft with the same number 40 and spandex at the core. Covered with a density of 200 x 140 pieces / inch Cover factor: 25.8 Weft: 22.1 ordinary satin stretch fabric with 200: 1 x 140 pieces / inch density with front and back tissue points 4: 1 When a satin fabric having a normal 12 mm width diagonal ear was processed in the same manner as in the above example, the ear was folded and the ear was wound.
[0015]
Comparative Example 2
When the oblique ear tissue described in Comparative Example 1 was widened to a width of 20 mm and processed in the same manner, a partial improvement was observed, but it was not completely eliminated.
[0016]
【The invention's effect】
In the present invention, in a tissue having a large difference between the front and back tissue points, the second ear tissue is formed on the inner side adjacent to the original ear tissue, thereby obtaining a characteristic that does not cause ear folding or ear winding during processing. Is.
