Abstract

In one aspect, a textile component including bulking yarn is disclosed. In embodiments, the textile component is a knitted component. In one embodiment, an article of footwear includes a knitted component arch support configured to reduce the rate of pronation. A support structure may include a fusible yarn adjacent to an external surface of the arch support, a bulking yarn, and a nonfusible yarn. In certain embodiments, an arch support includes compartments and flex lines. In another aspect, an article having a knitted component includes a rigid material, a bulking yarn, and a flexible material. The rigid material may be fusible yarn. Methods for forming a textile component are provided. One embodiment involves knitting a first section comprising a fusible yarn, a second section comprising a bulking yarn, and a third section comprising a nonfusible yarn, and heating.

First claim

We claim:

1. An article of footwear comprising a textile component arch support, the arch support comprising:
a) a first section formed from a fusible yarn and disposed adjacent to an external surface of the article of footwear, wherein the external surface comprises part of an outsole;
b) a second section formed from a bulking yarn and disposed adjacent to the first section; and
c) a third section formed from a non-fusible yarn, the third section disposed adjacent to the internal surface of the article of footwear and opposite the first section,
wherein the third section is separable from the first section such that a pocket is formed between the first section and the third section, the second section being inside the pocket.

2. The article of footwear of claim 1 , wherein the textile component is a knitted component.

3. The article of footwear of claim 1 , wherein the arch support reduces the rate of pronation of the foot.

4. The article of footwear of claim 1 , wherein the arch support further comprises a monofilament yarn disposed between the first section and the second section.

5. The article of footwear of claim 1 , wherein the bulking yarn has a first state and a second state, the second state having an increased loft relative to the first state, wherein the bulking yarn transitions from a first state to a second state on heating.

6. The article of footwear of claim 1 , wherein the fusible yarn melts upon heating to form a more rigid material, as compared to the fusible yarn before heating.

7. The article of footwear of claim 1 , wherein the arch support is divided into compartments.

8. The article of footwear of claim 1 , wherein the arch support comprises flex lines that flex in response to motion of the article of footwear.

9. An article comprising a textile component, the textile component comprising:
a) a first section comprising a first material and disposed adjacent to an external surface of the article, wherein the external surface comprises part of an outsole;
b) a second section comprising a bulking yarn and disposed adjacent to the first section; and
c) a third section comprising a second material and unsecured to the first section such that a pocket is formed between the first section and the third section,
wherein the first material is relatively rigid, as compared to the second material, and
wherein the second section is disposed between the first section and the third section.

10. The article of claim 9 , wherein the textile component is a knitted component.

11. The article of claim 9 , wherein the third section is disposed adjacent to the internal surface of the article.

12. The article of claim 9 , wherein the first material comprises a fusible yarn that melts upon heating, or a stiffened plate.

13. The article of claim 9 , wherein the third material comprises a non-fusible yarn.

14. The article of claim 12 , wherein the knitted component comprises a support structure for an article of footwear.

15. The article of claim 14 , wherein the support structure comprises an arch support or heel counter.
