Abstract

Aspects herein are directed to a composite nonwoven textile that includes non-linear entangled seams and method and systems for producing the same. The composite nonwoven textile includes at least a first nonwoven layer, a second layer, and a fill material positioned between the first nonwoven layer and the second layer. When the composite nonwoven textile is formed into a garment, the regions between the non-linear entangled seams may help store and retain heat to provide insulation, and the non-linear entangled seams may help prevent shifting or drift of the fill material.

First claim

What is claimed is:

1. A garment comprising:
a first nonwoven layer having a material flow direction;
a second layer;
a fill material positioned between the first nonwoven layer and the second layer;
at least one region of the garment where the first nonwoven layer, the second layer, and the fill material are substantially unentangled; and
at least one non-linear entangled seam extending along the material flow direction, the at least one non-linear entangled seam comprising one or more entanglement areas extending from each other to form the at least one non-linear entangled seam, wherein the one or more entanglement areas comprise fibers from the first nonwoven layer that extend through the fill material and into the second layer.

2. The garment of claim 1 , wherein the second layer is a nonwoven material.

3. The garment of claim 1 , wherein the one or more entanglement areas comprise discrete areas.

4. The garment of claim 1 , wherein a thickness of the at least one region of the garment where the first nonwoven layer, the second layer, and the fill material are substantially unentangled is from about 7 mm to about 15 mm.

5. The garment of claim 4 , wherein a thickness of the at least one non-linear entangled seam is from about 5% to about 30% of the thickness of the at least one region of the garment where the first nonwoven layer, the second layer, and the fill material are substantially unentangled.

6. The garment of claim 1 , wherein the fill material is one or more of a sheet of synthetic fibers, loose synthetic fibers, and down.

7. The garment of claim 1 , wherein the second layer is a woven material.

8. The garment of claim 1 , wherein the one or more entanglement areas partially overlap each other.

9. The garment of claim 1 , further comprising a plurality of additional non-linear entangled seams, wherein the plurality of additional non-linear entangled seams forms a non-repeating visual arrangement of entangled seams.

10. A composite nonwoven textile comprising:
a first nonwoven layer having a material flow direction;
a second layer;
a fill material positioned between the first nonwoven layer and the second layer;
at least one region of the composite nonwoven textile where the first nonwoven layer, the second layer, and the fill material are substantially unentangled; and
at least one non-linear entangled seam extending along the material flow direction, the at least one non-linear entangled seam comprising one or more entanglement areas extending from each other to form the at least one non-linear entangled seam, wherein the one or more entanglement areas comprise fibers from the first nonwoven layer that extend through the fill material and into the second layer.

11. The composite nonwoven textile of claim 10 , wherein the second layer is a nonwoven material.

12. The composite nonwoven textile of claim 10 , wherein the one or more entanglement areas comprise discrete entanglement areas.

13. The composite nonwoven textile of claim 10 , wherein a thickness of the at least one region of the composite nonwoven textile where the first nonwoven layer, the second layer, and the fill material are substantially unentangled is from about 7 mm to about 15 mm.

14. The composite nonwoven textile of claim 10 , wherein a thickness of the at least one non-linear entangled seam is from about 5% to about 30% of the thickness of the at least one region of the composite nonwoven textile where the first nonwoven layer, the second layer, and the fill material are substantially unentangled.

15. The composite nonwoven textile of claim 10 , wherein the fill material is one or more of a sheet of synthetic fibers, loose synthetic fibers, and down.

16. The composite nonwoven textile of claim 10 , wherein the second layer is a woven material.

17. The composite nonwoven textile of claim 10 , wherein the one or more entanglement areas partially overlap each other.

18. The composite nonwoven textile of claim 10 , further comprising a plurality of additional non-linear entangled seams, wherein the plurality of additional non-linear entangled seams forms a non-repeating visual arrangement of entangled seams.

19. A garment comprising:
a nonwoven textile having a material flow direction; and
at least one non-linear entangled seam extending along the material flow direction, the at least one non-linear entangled seam comprising one or more entanglement areas extending from each other to form the at least one non-linear entangled seam, wherein at each of the one or more entanglement areas, fibers forming the nonwoven textile have a generally vertical orientation.

20. The garment of claim 19 , wherein the one or more entanglement areas partially overlap each other.
