Abstract

Methods and systems are provided for a process to generate a nonwoven textile. In one example, the nonwoven textile may have layered, zonal properties resulting from entangling of two or more types of staple fibers through a merging region between the layers of staple fibers while maintaining distinct zones, each zone comprising a type of staple fiber. Furthermore, the process may include embedding a filament layer into the nonwoven textile via a continuous assembly line.

First claim

The invention claimed is:

1. A nonwoven textile, comprising:
a first fiber zone and a second fiber zone, the first fiber zone including-a first staple fibers and the second fiber zone including-a second staple fibers, wherein the first staple fibers of the first zone is are at least partially aligned in orientation with the staple fibers of the second zone along a length and/or width of the textile, the first fiber zone positioned in a depth-wise direction above the second fiber zone, wherein the first staple fiber is a different type of staple fiber than the second staple fiber,
a continuous filament at least partially aligned in orientation along the length and/or width with some of the first staple fibers and some of the second staple fibers and incorporated as a distinct layer separate from the first fiber zone and the second fiber zone, the distinct layer defined by the continuous filament being disposed and oriented along the length in a sinuous zig-zag pattern across the width, wherein the continuous filament comprises a low melt polymer having a melting point relatively lower than that of the first staple fiber and the second staple fiber.

2. The textile of claim 1 , wherein the different type of staple fiber comprises a different color, different material, different rigidity, and/or different melting point.

3. The textile of claim 1 , wherein the first fiber zone defines a first surface of the textile and the second fiber zone defines a second, opposite surface of the textile.

4. The textile of claim 2 , wherein the first staple fibers comprise carded first staple fibers, and wherein the second staple fibers comprise carded second staple fibers.

5. The textile of claim 1 , wherein the first staple fiber and/or the second staple fiber further differ from the continuous filament by one or more of differing color, differing material, and differing rigidity.

6. The textile of claim 1 , wherein a thickness of the first fiber zone is different from a thickness of the second fiber zone.

7. The textile of claim 1 , wherein the first fiber zone is felted to the second fiber zone along a depth of the textile.

8. The textile of claim 1 , wherein the textile is used in one or more of an article of apparel and an article of footwear.

9. A nonwoven textile, comprising:
a first zone of carded, horizontally aligned first staple fibers;
a second zone of carded, horizontally aligned second staple fibers, wherein the first staple fiber is a different type of staple fiber than the second staple fiber; and
a third zone intermediate the first and second zone, wherein the first, second, and third zone are vertically aligned relative to one another,
wherein the third zone comprises a horizontally aligned continuous filament as a distinct layer, wherein the horizontal alignment is provided by a pleating along a length of the textile in a sinuous zig-zag pattern across a width of the textile, wherein the continuous filament comprises a low melt polymer having a melting point relatively lower than that of the first staple fiber and the second staple fiber.

10. The textile of claim 9 , wherein the first zone is positioned on top of the second zone along a vertical perpendicular to the horizontally aligned first and second staple fibers and the first zone defines a top surface of the textile and the second zone defines a bottom surface of the textile.

11. The textile of claim 9 , wherein the different type of staple fiber differs in at least one physical property and/or material.

12. The textile of claim 9 , wherein the first staple fibers and/or the second staple fibers further differ from the continuous filament by one or more of differing color, differing material, and differing rigidity.

13. The textile of claim 9 , wherein the low melt polymer enables post-processing heat treatment to activate the distinct layer.

14. A nonwoven textile, comprising:
a first fiber zone, a second fiber zone, and a continuous filament, the first fiber zone comprising first staple fibers and the second fiber zone comprising second staple fibers,
wherein the continuous filament is incorporated as a distinct layer between the first fiber zone and the second fiber zone, the distinct layer defined by the continuous filament being disposed and oriented along a length of the textile in a sinuous zig-zag pattern across a width of the textile, wherein the continuous filament comprises a low melt polymer having a melting point relatively lower than that of the first staple fiber and the second staple fiber,
wherein at least some of the first staple fibers and some of the second staple fibers are at least partially aligned in orientation with the continuous filament, and wherein the first staple fiber is a different type of staple fiber than the second staple fiber.

15. The textile of claim 14 , wherein the first staple fibers comprise carded first staple fibers, and wherein the second staple fibers comprise carded second staple fibers.

16. The textile of claim 14 , wherein the first fiber zone defines a first surface of the textile and the second fiber zone defines a second, opposite surface of the textile.

17. The textile of claim 14 , wherein the different type of staple fiber comprises a different color, different material, different rigidity, and/or different melting point.

18. The textile of claim 14 , wherein the first staple fiber and/or the second staple fiber further differ from the continuous filament by one or more of differing color, differing material, and differing rigidity.

19. The textile of claim 14 , wherein the first fiber zone excludes the second staple fiber.

20. The textile of claim 14 , wherein the second fiber zone excludes the first staple fiber.
