Abstract

By rethinking the organizational structure, we create a multi-layered structure, resulting in a fabric whose color appears to change depending on the angle of light hitting it. [Solution] The present invention is characterized in that the fabric is plain woven with a base structure in which the warp threads 1 alternately cross over the weft threads 2 every two passes, and a gradient foil 3 is woven in with fine stitching on top of the gradient foil 3, and a silver foil 4 is woven in with coarse stitching on top of the gradient foil 3.

[0001] The present invention relates to a fabric that appears to change color every time the angle of light hitting the fabric changes due to tissue changes.

Background Art

[0002] Conventional fabric structures are formed by the combination of warp and weft threads. For plain weave, there is a plain weave structure; for twill weave, there is a twill weave structure; for jacquard weave, there is a jacquard weave structure. The laws of fabric structures are determined.

Summary of the Invention

Problems to be Solved by the Invention

[0003] I wondered if I could find something by reexamining the fabric structure or create a multi-layered structure. Since there is a double weave structure in the conventional twill weave, I invented a new fabric with this as a reference example.

[0004] The object of the present invention is to provide a fabric that has a multi-layered structure by reexamining the fabric structure and appears to change color every time the angle of light hitting the fabric changes.

Means for Solving the Problems

[0005] To achieve the above object, the fabric of the present invention is characterized in that a first foil (3) is woven in with fine stitching on top of a ground structure formed by alternately crossing the ground warp threads (1) up and down every two over the ground weft threads (2) to form a plain weave, and a second foil (4) is woven in with rough stitching on top of the first foil (3).

Effects of the Invention

[0006] [[ID=4C]]According to the present invention, it is possible to provide a fabric that appears to change color every time the angle of light hitting the fabric changes.

Brief Description of the Drawings

[0008] Specific embodiments of the present invention will be described with reference to Figures 1 to 4. As shown in Figures 1 to 4, in the fabric of the present invention, a plain weave ground structure is first created by crossing each warp thread 1 with two warp threads 2 in the same direction. That is, adjacent warp threads 1a and 1b are woven by crossing each pair of warp threads 2 (two crosses) of warp threads 2a (first cross) and warp thread 2b (second cross). In Figure 1, the light gray areas of the ground structure show the warp threads 2 resting on top of the warp threads 1, while the dark gray areas show the warp threads 2 hidden beneath the warp threads 1. On top of this ground structure, a finely stitched first foil, a shaded foil 3 (right diagonal), is woven, and on top of the shaded foil 3, a coarsely stitched second foil, a silver foil 4 (left diagonal), is woven.

[0009] As shown in Figure 2, the gradient foil 3 is woven into the base fabric by fine stitching with the underlay threads 5 and 6 at a rate of once every 6 warp threads 1. On the other hand, the silver foil 4 is woven into the base fabric together with the gradient foil 3 by coarse stitching with the underlay threads 4, at a rate of once every 12 warp threads 1. Thus, the silver foil 4 is woven into the base fabric more coarsely than the gradient foil 3, using underlay threads with half the density of the gradient foil 3. Also, as shown in Figure 1, the underlay threads 5 and 6 are each offset by the width of 3 warp threads 1 in the horizontal direction every 2 passes.

[0010] Theoretically, the gradient foil 3 rests on the ground weft thread 2a of the first pass, and the silver foil 4 rests on the ground weft thread 2b of the second pass and on top of the gradient foil 3, overlapping as they are woven. However, in reality, due to the combination of the weave structure and the material of the ground weft thread 2, gaps are created between the ground warp thread 1 and the foil combination. Therefore, although the gradient foil 3 rests on the ground weft thread 2a of the first pass, due to the weave structure, the ground warp threads 1a and 1b cross vertically every two passes, so as shown in Figure 3, it settles in front of the ground weft thread 2a of the first pass, sloping downward along the slope of the ground warp thread 1. Similarly, as shown in Figure 3, the silver foil 4 settles behind the ground weft thread 2b of the second pass, sloping downward along the slope of the ground warp thread 1. Therefore, although the silver foil 4 overlaps the gradient foil 3, it does not overlap directly on top, but slightly shifted backward. As a result, the foil surfaces of the gradient foil 3 and the silver foil 4 are woven in a mountain shape that is slightly sloped downward in the front and back.

[0011] When light shines on the fabric of the present invention woven as described above, the reflected light from the shading foil 3 and silver foil 4 becomes iridescent depending on the angle of the light. The inventor discovered that this causes the overall color balance of the fabric to become irregular, resulting in a change in how the colors appear.

[0012] Let us explain in more detail using Figure 4. The fabric of the present invention shown in Figure 4 is an example in which the ground structure is created by weaving a thicker weft thread 2a for the first pass and a thinner weft thread 2b for the second pass. The range of motion of the finely bound shading foil 3, held down by the binding threads 6 and 5, in the front-to-back direction is between the intersection 7a of the ground warp threads 1a and 1b in front of the ground weft thread 2a for the first pass and the intersection 7b of the ground warp threads 1a and 1b behind the ground weft thread 2b for the second pass. As a result, depending on the degree of weaving, the shading foil 3 is woven in at an angle downward along the slope of the ground warp thread 1a in front of the ground weft thread 2a, as shown in Figure 4. As mentioned above, the silver foil 4 is bound to the ground structure at only half the density of the shading foil 3, so the range of motion of the silver foil 4 is even larger than that of the shading foil 3.

[0013] The gradient foil 3 rests on the thick ground weft thread 2a and does not move much due to the fine stitching. The silver foil 4 moves appropriately within its range of motion due to changes in the structure, so its position changes from time to time. The silver foil 4 also settles at the boundary between the ground weft threads 2a and 2b, or at the part that overlaps with the gradient foil 3 (this overlap is also not constant), with the part in front and the part behind the ground weft thread 2b tilted downward along the slope of the ground warp thread 1a. In this way, by making the thickness of the first ground weft thread 1a thicker than the second ground weft thread 2b, it is expected that the brightness of the reflected light from the gradient foil 3 and silver foil 4 of the present invention will increase, and the change in the appearance of the overall color of the fabric will also increase.

[0014] In this embodiment, the first foil on the base material was described as gradient foil 3 and the second foil as silver foil 4, but these are not limited to gradient foil or silver foil, as long as they are materials that reflect light when it hits them. Furthermore, the density and arrangement of the binding threads 5 and 6 used for fine and coarse binding to the base fabric are not limited to this embodiment. [Explanation of Symbols]
