Physical properties to protect the wearer's feet and durability to withstand external stimuli are important for shoe uppers.

As described above, in order to increase the marketability of shoes, fabrics manufactured by weaving warp and weft yarns have recently been in the limelight as shoe upper materials. Fabrics not only have excellent durability, but also can easily implement various patterns and colors, so that the aesthetics of shoes can be easily improved, which has the effect of increasing the marketability of shoes more effectively.

However, when stretchable yarns having elasticity with at least one of the warp and weft yarns are applied to the textile fabric on which the shoe upper design is formed, the textile fabric is heat-treated during the post-processing process so that the textile fabric can be used as the shoe upper. There was a problem that the upper design was distorted due to irregular contraction, and the meandering degree of the fabric fabric was bent or distorted.

That is, in the case of textile fabrics with shoe upper designs, it was difficult to apply yarns with elasticity, so yarns without elasticity had to be applied. Accordingly, when using textile fabrics with shoe upper designs as shoe upper materials, shoe uppers There was a problem that the fit of the shoe was deteriorated because it was not stretched.

In addition, since yarns with elasticity cannot be applied, it is difficult to implement a three-dimensional structure in the form of 3D in the fabric fabric on which the shoe upper design is formed. As the fabric fabric has a flat structure in the form of 2D, There was a problem that was difficult to differentiate by diversifying more.

<Test Example 1>

In Test Example 1, the fabric fabrics 10 prepared according to Examples 1 to 5 and Comparative Examples 1 to 5 were tested using a gauge film 20 to confirm that they did not warp and shrink uniformly after heat treatment.

(1) Production of gauge film

Before washing and heat-treating the woven fabric fabric 10, the upper surface of the fabric fabric 10 was scanned to create an image on a computer.

Using a computer, the size of the image file generated so that the width of the image matches the width after washing and heat-treating the woven fabric 10 was reduced, but the size of the image was reduced while maintaining the aspect ratio of the image constant. .

The gauge film 20 was manufactured by printing the first to third cross marks (A, B, C) on the boundary between the upper skin 11 and the margin 12 of the shrunken image on a transparent film.

12 is a photograph of the gauge film 20 used in Test Example 1. Referring to FIG. 12, it can be seen that the gauge film 20 has a structure in which the upper part, the boundary between the upper part and the margin part (D), and the first to third cross marks (A, B, C) are formed on a transparent film. .

(2) Test method

Gauge films 20 corresponding to each of them were adhered to the fabric fabrics 10 prepared according to Examples and Comparative Examples. At this time, the intersection of the second cross mark (B) formed in the middle of the fabric fabric (10) and the second cross mark (B) formed on the gauge film 20 corresponding to the second cross mark (B), the direction of the horizontal line and The directions of the vertical lines were closely aligned with each other.

The center of the first cross mark (A) formed on the top of the textile fabric (10) in a state where the fabric fabric (10) and the gauge film (20) are in close contact, and the gauge film (20) corresponding to the first cross mark (A). The first distance, which is the distance between the centers of the first cross marks (A) of ), was measured.

The center of the third cross mark (C) formed on the top of the textile fabric (10) in a state where the fabric fabric (10) and the gauge film are in close contact, and the third cross mark (C) of the gauge film (20) corresponding to the third cross mark (C). The second distance, which is the distance between the centers of the three cross marks (C), was measured.

In addition, a third distance, which is the distance between the boundary between the upper skin 11 and the blank portion 12 of the fabric fabric 10 and the boundary (D) between the upper skin and the blank portion marked on the gauge film 20, was measured. At this time, Boundary (D) between the upper skin 11 and the marginal portion 12 of the gauge film 20 located on a horizontal line from a point at the boundary between the upper skin 11 and the marginal portion 12 of the fabric fabric 10 Among the distances to a point on the image, the longest one was measured.

If at least one of the first distance, the second distance, and the third distance exceeds 4 mm, it was determined that the fabric fabric 10 was not uniformly contracted and warped.

(3) Test results

The test results are summarized in Table 1 below.

1st distance (mm) 2nd distance (mm) 3rd distance (mm) False or not Example 1 One 0 One X Example 2 One 0 2 X Example 3 One 2 One X Example 4 One 2 One X Example 5 2 One 2 X Comparative Example 1 One One One X Comparative Example 2 4 4 5 O Comparative Example 3 3 5 4 O Comparative Example 4 5 2 4 O Comparative Example 5 0 0 One X

Referring to Table 1, it can be seen that the first to third distances of the fabric fabric 10 according to Examples 1 to 5 are all 4 mm or less, which means that the fabric fabric 10 according to Examples 1 to 5 is meandering during heat treatment. This is a result that can confirm that the sword is contracted uniformly without bending or distortion.

It can be seen that all of the first to third distances of the fabric fabric 10 according to Comparative Example 1 are 4 mm or less, which means that the area of the three-dimensional tissue 100 compared to the total area of the fabric fabric 10 is reduced to form the three-dimensional tissue 100. It is determined that the degree of shrinkage of the fabric fabric 10 is not large due to this.

In the fabric fabric 10 according to Comparative Example 5, it can be confirmed that the first to third distances are all 4 mm or less, which means that the warp yarn 13, the first weft yarn 14 and the second weft yarn ( 15) is determined to be due to the fact that there is no difference in shrinkage and elasticity throughout the fabric fabric 10 by using the same yarn.

In the fabric fabric 10 according to Comparative Example 2, it can be seen that the meandering degree is bent and distorted because the third distance exceeds 4 mm. As the three-dimensional structure 100 is excessively contracted, it can be confirmed that the meandering degree of the fabric fabric 10 is bent and distorted.

In the fabric fabric 10 according to Comparative Example 3, it can be confirmed that the meandering degree is bent and distorted because the second distance exceeds 4 mm, which indicates that the three-dimensional tissue 100 included in the upper skin 11 is the margin portion 12 It is a result that can confirm that the meandering degree of the fabric 10 is bent and distortion occurs due to excessive contraction than the upper skin 11 and the margin portion 12 as compared to the three-dimensional tissue 100 included in .

It can be seen that the first distance according to Comparative Example 4 exceeds 4 mm, so that the fabric fabric 10 is distorted. It is a result of confirming that the meandering degree of the fabric 10 is bent and distortion occurs due to excessive contraction than the margin part 12 and the upper skin 11 as compared to the tissue 100.
