Abstract

A woven material including a four layer construction formed by distinct groups of warp threads, and a method of forming the woven material. The woven material may include a first group of warp threads, and an interior weft thread portion coupled to the first group of warp threads. The woven material may also include a second group of warp threads substantially surrounding the first group of warp threads and the interior weft thread portion, and an exterior weft thread portion coupled to the second group of warp threads.

First claim

We claim:

1. A woven material comprising:
a continuous weft thread comprising an interior weft thread portion and an exterior weft thread portion;
a first group of warp threads, the interior weft thread portion interwoven with and directly contacting each of the first group of warp threads in a first length of the woven material;
a second group of warp threads substantially surrounding the first group of warp threads and the interior weft thread portion in the first length of the woven material, the exterior weft thread portion interwoven with and directly contacting each of the second group of warp threads in the first length of the woven material;
wherein, between the first length of the woven material and a second length of the woven material, the first group of warp threads and the second group of warp threads switch positions such that, in the second length of the woven material, the first group of warp threads is substantially surrounding the second group of warp threads.

2. The woven material of claim 1 , wherein the first group of warp threads include at least one color thread.

3. The woven material of claim 2 , wherein the second group of warp threads include at least one color thread, wherein the at least one color thread of the second group of the warp threads is distinct from the at least one color thread of the first group of the warp threads.

4. The woven material of claim 1 , further comprising:
a top surface including a top portion of the second group of warp threads and the exterior weft thread portion; and
a bottom surface positioned opposite the top surface, the bottom surface including a bottom portion of the second group of warp threads and the exterior weft thread portions.

5. The woven material of claim 4 , further comprising connecting yarns coupled to at least one of the interior weft thread portion and the exterior weft thread portion.

6. The woven material of claim 5 , wherein the connecting yarns are coupled to:
the exterior weft thread portion included within the top surface; and
the exterior weft thread portion included within the bottom surface.

7. The woven material of claim 5 , wherein the connecting yarns include:
a first collection of connecting yarns coupled to:
the exterior weft thread portion included within the top surface; and
the interior weft thread portion; and
a second collection of connecting yarns positioned opposite the first collection of connecting yarns, the second collection of connecting yarns coupled to:
the exterior weft thread portion included within the bottom surface; and
the interior weft thread portion.

8. The woven material of claim 7 , further comprising an opening positioned between the top surface and the bottom surface.

9. The woven material of claim 4 , further comprising:
a first layer including the top portion of the second group of warp threads and the exterior weft thread portion forming the top surface;
a second layer positioned directly adjacent the first layer, the second layer including a first portion of the first group of warp threads and the interior weft thread portion;
a third layer positioned directly adjacent the second layer, the third layer including a second portion of the first group of warp threads and the interior weft thread portion; and
a fourth layer positioned directly adjacent the third layer and opposite the first layer, the fourth layer including the bottom portion of the second group of warp threads and the exterior weft thread portions forming the bottom surface.

10. The woven material of claim 9 , wherein each of the warp threads in the top portion of the second group of warp threads included in the first layer are substantially aligned with a corresponding warp thread in:
the first portion of the first group of warp threads included in the second layer;
the second portion of the first group of warp threads included in the third layer; and
the bottom portion of the second group of warp threads included in the fourth layer.

11. The woven material of claim 10 , wherein, between a first section of the woven material and a second section of the woven material, a warp thread included in the top portion of the second group of warp threads included in the first layer switches positions with a warp thread included in the first portion of the first group of warp threads included in the second layer.

12. The woven material of claim 10 , wherein, between a first section of the woven material and a second section of the woven material, a warp thread included in the bottom portion of the second group of warp threads included in the fourth layer switches positions with a warp thread included in the second portion of the first group of warp threads included in the third layer.

13. A wearable band comprising:
a woven material including, in a first length of the woven material:
a first warp thread positioned within a first layer of the woven material;
a second warp thread positioned within a second layer of the woven material;
a third warp thread positioned within a third layer of the woven material; and
a fourth warp thread positioned within a fourth layer of the woven material; and

a weft thread coupled to and in direct contact with the first, second, third, and fourth warp threads, wherein the weft thread extends through each of the first, second, third, and fourth layers of the woven material;
wherein the second layer is between the first and third layers, and the third layer is between the second and fourth layers;
wherein, between the first length of the woven material and a second length of the woven material, the first warp thread and the second warp thread switch positions, such that, in the second length of the woven material:
the first warp thread is positioned within the second layer of the woven material;
the second warp thread is positioned within the first layer of the woven material;
the third warp thread is positioned within the fourth layer of the woven material; and
the fourth warp thread is positioned within the third layer of the woven material.

14. The wearable band of claim 13 , wherein the first warp thread is positioned on one of the top surface or the bottom surface of the woven material in a second section of the length of the woven material.

15. The wearable band of claim 14 , wherein the second warp thread is positioned within the inner portion of the woven material in the second section of the length of the woven material.

16. The wearable band of claim 13 , wherein:
in the first section, the first warp thread is in a first position within the inner portion of the woven material and the second warp thread is in a second position on the top surface and the bottom surface of the woven material; and
in the second section, the first warp thread is in the second position and the first warp thread is in the first position.

17. A woven material comprising:
first warp threads;
second warp threads;
third warp threads;
fourth wrap threads; and
a continuous weft thread coupled to and in direct contact with each of the first warp threads, the second warp threads, the third warp threads, and the fourth warp threads;
wherein:
in a first length of the woven material, the second warp threads define a first exterior surface of the woven material, the third warp threads define a second exterior surface of the woven material, and the second and third warp threads substantially surround the first and fourth warp threads; and
in a second length of the woven material, the first warp threads define a second exterior surface of the
