Abstract

A layered non-woven textile may be incorporated into various products, including apparel. The layered non-woven textile may be formed from a first layer and a second layer. The first layer is formed from a plurality of first filaments that include a first thermoplastic polymer material with a first melting temperature. The second layer is located adjacent to the first layer and secured to the first layer. The second layer is formed from plurality of second filaments that include a second thermoplastic polymer material with a second melting temperature. The first melting temperature is lower than the second melting temperature.

Claims

1. A non-woven textile comprising:

a first layer formed from a plurality of first filaments that include a first thermoplastic polymer material with a first melting temperature;

the first layer including a fused region having a continuous area of at least one square centimeter, wherein the first filaments are fused within the fused region to form a non-filamentous portion of the first layer in the fused region; and

a second layer located adjacent to the first layer and secured to the first layer, the second layer being formed from plurality of second filaments that include a second thermoplastic polymer material with a second melting temperature, the first melting temperature being lower than the second melting temperature.

2. The non-woven textile recited in claim 1, wherein the first thermoplastic polymer material and the second thermoplastic polymer material are thermoplastic polyurethane materials.

3. The non-woven textile recited in claim 1, wherein the fused region is adjacent a first region and a second region, wherein the first region has a first thickness, the second region has a second thickness, and the fused region has a third thickness, wherein the first thickness and the second thickness are substantially the same, and wherein the third thickness is less than the first thickness.

4. The non-woven textile recited in claim 1, wherein the second layer includes a filamentous region adjacent to the fused region of the first layer.

5. The non-woven textile recited in claim 1, wherein a component is secured to the fused region.

6. The non-woven textile recited in claim 1, wherein a plurality of strands are embedded within the non-woven textile, the strands extending in a direction that is substantially parallel to a surface of the second layer for a distance of at least five centimeters, and wherein the strands are at least partially embedded in the fused region.

7. The non-woven textile recited in claim 6, wherein the strands are located between the first layer and the second layer.

8. The non-woven textile recited in claim 1, wherein the non-woven textile is incorporated into an article of apparel.

9. The non-woven textile recited in claim 1, wherein the non-woven textile is incorporated into an article of footwear.

10. An article of apparel comprising:

a non-woven textile including (a) a first layer formed from a plurality of first filaments that include a first thermoplastic polymer material with a first melting temperature, wherein the first layer has a first area and (b) a second layer located adjacent to the first layer, the second layer formed from plurality of second filaments that include a second thermoplastic polymer material with a second melting temperature, the first melting temperature being lower than the second melting temperature, wherein the first layer includes at least one fused region having a continuous area of at least one square centimeter, the first filaments being fused to form a non-filamentous portion of the non-woven textile in the fused region; and

a component attached to the first layer, wherein the component has a component area, the component is aligned with the fused region, and wherein the component area is less than the first area.

11. The article of apparel recited in claim 10, wherein the first layer forms a portion of an exterior surface of the apparel, and the second layer forms a portion of an interior surface of the apparel.

12. The article of apparel recited in claim 10, wherein the second layer includes a filamentous region adjacent to the fused region of the first layer.

13. The article of apparel recited in claim 10, wherein the component is heatbonded to the first layer at the fused region.

14. An article of footwear comprising:

an upper and a sole structure, the upper comprising a non-woven textile having (a) a first layer formed from a plurality of first filaments that include a first thermoplastic polymer material with a first melting temperature and (b) a second layer located adjacent to the first layer, the second layer formed from plurality of second filaments that include a second thermoplastic polymer material with a second melting temperature, the first melting temperature being lower than the second melting temperature, the first layer being positioned to form at least a portion of an exterior surface of the footwear, and the second layer being positioned inward of the first layer; and

wherein the first layer includes a fused region having a continuous area of at least one square centimeter, the first filaments being fused to form a fused region, wherein the fused region defines a non-filamentous portion of the non-woven textile and the remainder of the first layer includes a filamentous portion.

15. The article of footwear recited in claim 14, wherein the second layer includes a filamentous region adjacent to the fused region of the first layer.

16. The article of footwear recited in claim 14, wherein a component is heatbonded to the non-woven textile in the fused region.

17. The article of footwear recited in claim 16, wherein the component is selected from a group consisting of a toe cap, a heel counter, and indicia.

18. The article of footwear recited in claim 14, wherein a plurality of strands are embedded within the first layer.

19. The article of footwear recited in claim 18, wherein the strands extend from a lace region of the upper to a region that is adjacent to the sole structure.

20. The article of footwear recited in claim 18, wherein the strands are located at least partially within the fused region.

21. An article of apparel comprising:

a non-woven textile including (a) a first layer formed from a plurality of first filaments that include a first thermoplastic polymer material with a first melting temperature and (b) a second layer located adjacent to the first layer, the second layer formed from plurality of second filaments that include a second thermoplastic polymer material with a second melting temperature, the first melting temperature being lower than the second melting temperature; and

wherein the second layer includes at least one fused region comprising a partially filamentous portion and a partially non-filamentous portion of filaments.

22. The article of apparel recited in claim 21, wherein the first layer forms a portion of an interior surface of the apparel, and the second layer forms a portion of an exterior surface of the apparel.

23. The article of apparel recited in claim 21, further comprising a plurality of strands at least partially embedded in the first layer, the strands being formed from a material that is different than the first thermoplastic material and the second thermoplastic material.

24. The article of apparel recited in claim 21, wherein the apparel is footwear.
