Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soccer-like ripstop fabric having a natural unevenness and an excellent feeling of firmness and stiffness.

[0002]

2. Description of the Related Art Conventionally, various methods have been proposed for imparting irregularities to the surface of a woven fabric. For example, football fabrics are well known. This is to warp several warp yarns for a long time during warping and to sag the warp during weaving to create a feeling of unevenness on the surface of the woven fabric. Also, a method of arranging several yarns having different heat shrinkage ratios at the time of warping and expressing a difference in heat shrinkage during dyeing and finishing after weaving to generate irregularities on the surface of the fabric is also known. . However, these methods have a problem that complicated warping has to be performed and the production efficiency is very poor.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides a soccer ball having a natural unevenness on the surface of a woven fabric and an excellent feeling of stiffness without complicated warping. The technical task is to supply a lip-stop woven fabric.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, the ground yarns have been aligned in a woven fabric structure to form a warp portion having a high yarn density. In the woven fabric that forms the ripstop consisting of weft ridges, the intersection of the warp ridge and the weft ridge where several ground yarns are aligned forms an uneven part, giving a undulating appearance as a whole with a wavy appearance. I found that it could be a soccer-like ripstop fabric. That is, the present invention provides a ripstop fabric comprising a warp portion and a weft portion, wherein the warp portion and the weft portion are formed by aligning three to six ground yarns,
The gist of the invention is a soccer-like ripstop woven fabric characterized by having a corrugation at the intersection of the warp and weft ridges.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. According to the present invention, irregularities are expressed on the surface of a woven fabric by a weaving structure regardless of a yarn form, a yarn length difference, a heat shrinkage difference, and the like. In order to achieve this object, the present invention employs a ripstop pattern having a grid-like ridge.
The ripstop pattern is one in which the regular or irregular number of warp and weft yarns are arranged at regular or irregular intervals to develop lattice ridges on the surface.

The configuration of the present invention will be described with reference to the drawings. FIG.
1 is a schematic view of a soccer-like ripstop fabric of the present invention. An important requirement of the present invention is that the ridges forming the ripstop pattern are formed by aligning and fabricating 3 to 6 ground yarns. That is, the warp portion 1 in FIG. 1 is formed by pulling out 3 to 6 warp yarns, and the weft ridge portion 2 is formed by pulling out 3 to 6 weft yarns. The portion where the ridge portion 1 and the weft ridge portion 2 intersect is the intersection portion 3, which is a portion where uneven waviness appears. Irregular waving occurs at the intersection 4 where the warp portion and the weft of the ground structure intersect depending on the weaving conditions.

[0007] Here, it is necessary that the number of ground yarns forming the warp and weft ridges is 3 to 6 in each case. If the number of ground yarns of any warp yarn is less than three, the intersection of the warp and weft ridges does not form uneven waving, regardless of the number of other warp yarns. The feeling of firmness and stiffness becomes weak. Conversely, if the number of any of the warp yarns is more than 6, the unevenness of the weft yarn becomes very large, and although the feeling of firmness and stiffness is excellent, snagging is likely to occur in the final product. Disadvantages come out. The ridges and wefts forming the ripstop pattern of the present invention may be arranged at regular intervals or randomly at irregular intervals. In consideration of
~ 15 are preferred.

[0008]

The present inventors guess the mechanism by which the warp portion forms a convex portion at the intersection with the weft ridge portion, and the unevenness is generated at the intersection with the ground weft as follows. . Since several warps forming the warp portion are arranged in the ground structure, the warp becomes stronger than other warps in the ground structure. Therefore, in the warp portion, the degree of warp bending along the weft is smaller than that of the other ground yarns constituting the ground structure, and the warp becomes linear with less bending. Then, the weaving shrinkage decreases, and the thread length of the warp portion becomes surplus. However, when the warp length is exactly the same as the warp of the ground texture, the surplus amount is at the intersection with the weft ridge where several wefts are aligned and the warp of the warp has a high rigidity. Then, a convex portion is formed by floating from the surface of the weft ridge. In addition, the surplus amount still remains, and unevenness occurs even in places where there is no weft ridge adjacent to the ridges, and when compared to a flat ground structure part, it will be organized as a wavy unevenness .

[0009]

Next, the present invention will be described in detail with reference to examples. (1) Evaluation of the convex part at the intersection of the warp and weft ridges At the intersection of the warp and weft ridges, the unevenness of the flat ground structure consisting of ground warp and ground weft is considered. The presence or absence of waving was visually evaluated in the following three stages. ：: Clear unevenness was formed. Δ: A slight undulation is formed. ×: No corrugation was formed. (2) Evaluation of unevenness at the intersection of warp and ground weft At the intersection of warp with the weft of the ground texture, the unevenness of the flat ground texture consisting of ground warp and ground weft The presence or absence of wavy formation was evaluated by visual evaluation in the following three stages. ：: Clear unevenness was formed. Δ: A slight undulation is formed. ×: No corrugation was formed. (3) Evaluation of feeling (stiffness and firmness) For the final product woven fabric after finishing weaving,
The handling gave a firm and firm feeling in the following three stages. ○: Excellent △: Inferior ×: Very inferior (4) Appearance evaluation For the final product woven fabric that has been subjected to finishing after weaving,
The overall external aesthetics as a soccer-like ripstop fabric with a sense of unevenness was performed in the following three stages. ：: excellent △: inferior ×: extremely inferior (5) Snagging evaluation Test and evaluation by D-3 method (gold saw method) and A method (Mace method) according to JIS L-1058 Was done.

In Comparative Example 2 in which the number of warp alignments in the warp portion was less than 3, no wavy irregularities were formed at a portion where the warp portion and the weft ridge intersected and a portion where the warp portion and the ground weft crossed. Also, the feeling of firmness and stiffness was inferior, and it did not become a soccer-like woven fabric and was not subject to appearance evaluation. In Comparative Example 3 in which the number of aligned wefts in the weft ridge was less than three, no unevenness was formed at the intersection of the warp and weft ridges, the feeling of firmness and stiffness was weak, and the appearance was poor. . In Comparative Example 4 in which the number of weft alignments in the weft ridge was greater than 6, the appearance evaluation was poor, and the wavy irregularities at the intersection of the warp and weft ridges were extremely large. became. Further, in Comparative Example 5, in which the number of warp alignments in the warp portion was greater than 6, the unevenness of the warp was extremely large over the entire warp portion, and the appearance evaluation as a soccer-like ripstop fabric was inferior.
