Abstract

Multi-layered articles that include a first textile and an adhesive layer having a non-uniform adhesive pattern is provided. The non-uniform adhesive pattern creates regions free or substantially free of adhesive. The adhesive regions, together with the non-adhesive regions, create a visible pattern on the surface of the article. A second textile may optionally be bonded to the adhesive opposing the first textile to form a multi-layered article. The first textile or adhesive layer may be shrinkable or expandable. Additionally, the multi-layered article has a stretch force at 20% elongation of less than three times the stretch force of the first textile at 20% elongation. The multi-layered articles are breathable, insulative, aesthetically pleasing, and demonstrate superior stretch and recovery properties.

First claim

Having thus described the invention, what is claimed is:

1. A multi-layered article comprising:
a first textile; and
an adhesive layer positioned on said first textile, said adhesive layer containing two or more adhesive regions separated by regions substantially free of adhesive, each said adhesive region containing a plurality of adhesive dots,
wherein a distance between adjacent adhesive dots within said adhesive regions is less than a distance between consecutive adhesive regions,
wherein said adhesive regions have at least one distinctive shape,
wherein each said adhesive region induces a radius of curvature that forms raised portions in said multi-layered article that correspond to said regions substantially free of adhesive, and
wherein said radius of curvature of said each said adhesive region is from about 1 mm to about 20 mm.

2. The multi-layered article of claim 1 , wherein said raised portions are positioned towards said first textile.

3. The multi-layered article of claim 1 , wherein said raised portions are positioned towards said adhesive layer.

4. The multi-layered article of claim 1 wherein said at least one distinctive shape is repeated two or more times.

5. The multi-layered article of claim 1 , wherein said distinctive shape has a geometric or abstract form.

6. The multi-layered article of claim 1 , wherein said multi-layered article has a stretch force at 20% elongation of less than three times the stretch force of said first textile at 20% elongation.

7. The multi-layered article of claim 1 , wherein said adhesive dots are distributed non-uniformly within said adhesive regions.

8. The multi-layered article of claim 1 , wherein said adhesive dots have substantially the same size within said adhesive regions.

9. The multi-layered article of claim 1 , wherein said adhesive dots differ in size within said adhesive regions.

10. The multi-layered article of claim 1 , wherein adhesive dots positioned in an outer portion of said adhesive regions have a diameter that is larger than a diameter of adhesive dots positioned on an inner portion of said adhesive regions.

11. The multi-layered article of claim 1 , wherein said regions substantially free of adhesive have a width greater than about 2 mm.

12. The multi-layered article of claim 1 , wherein a percent area coverage of said adhesive regions in said multi-layered article is at least 30%.

13. The multi-layered article of claim 1 , further comprising a second textile on said adhesive layer on a side opposing said first textile.

14. The multi-layered article of claim 1 , wherein said first textile is selected from an elastic textile and a shrinkable textile.

15. The multi-layered article of claim 1 , wherein said adhesive is a shrinkable adhesive.

16. The multi-layered article of claim 1 , wherein at least one of said first textile and said adhesive regions comprises a fire retardant or fire resistant material.

17. A garment comprising the multi-layered article of claim 1 .

18. A multi-layered article comprising:
a first textile; and
an adhesive layer positioned on said first textile, said adhesive layer containing first adhesive regions and second adhesive regions,
wherein said first adhesive regions contain an amount of adhesive that is greater than an amount of adhesive present in said second adhesive regions,
wherein said multi-layered article has a stretch force at 20% elongation of less than three times the stretch force of said first textile at 20% elongation
wherein each said first adhesive region induces a radius of curvature that forms raised portions in said multi-layered article that correspond to said second adhesive regions,
wherein said raised portions are positioned towards said first textile.

19. The multi-layered article of claim 18 , wherein said second adhesive regions have a width greater than about 2 mm.

20. The multi-layered article of claim 18 , wherein said first adhesive regions form at least one distinctive shape, said at least one distinctive shape being repeated two or more times and having a geometric or abstract form.

21. The multi-layered article of claim 18 , wherein said first adhesive regions contain a plurality of adhesive dots.

22. The multi-layered article of claim 21 , wherein said plurality of adhesive dots have substantially the same size.

23. The multi-layered article of claim 21 , wherein said first adhesive regions contain first adhesive dots positioned on an outer portion that have a diameter that is larger than a diameter of second adhesive dots positioned on an inner portion of said first adhesive regions.

24. The multi-layered article of claim 18 , wherein at least one of said first adhesive regions comprises a substantially continuous band of adhesive surrounding a plurality of adhesive dots.

25. The multi-layered article of claim 18 , wherein at least one of said first adhesive regions comprise strips of adhesive positioned within the first adhesive region such that the strips of adhesive are substantially parallel to each other with said regions substantially free of adhesive interspacing said strips of adhesive.

26. The multi-layered article of claim 18 , wherein at least one of said first adhesive regions comprises centrally located regions that are free or substantially free of adhesive.

27. The multi-layered article of claim 18 , wherein a percent area coverage of said first adhesive regions in said multi-layered article is at least 30%.

28. The multi-layered article of claim 18 , wherein said radius of curvature of said first adhesive regions is from about 1 mm to about 20 mm.

29. The multi-layered article of claim 18 , wherein at least one of said first textile and said first adhesive regions comprises a fire retardant or fire resistant material.

30. The multi-layered article of claim 18 , wherein said radius of curvature is greater than about 1 mm.

31. A garment comprising the multi-layered article of claim 18 .

32. A multi-layered article comprising:
a first textile; and
an adhesive layer positioned on said first textile, said adhesive layer containing at least one first region having a first percent area coverage of adhesive and at least one second region having a second percent area coverage of adhesive, said first percent area coverage of adhesive being greater than said second area coverage of adhesive,
wherein said first region forms at least one distinctive shape, said at least one shape being repeated two or more times and having a geometric or abstract form and
wherein each said first region having a first percent area of coverage induces a radius of curvature that forms raised portions in said multi-layered article that correspond to said second regions having a second percent area of coverage, and
wherein said at least one first region contains adhesive dots.

33. The multi-layered article of claim 32 , wherein said adhesive dots are distributed non-uniformly within said at least one first region.

34. The multi-layered article of claim 32 , wherein said adhesive dots positioned on an outer portion of said at least one first region have a diameter that is larger than said adhesive dots positioned on an inner portion of said at least one first region.

35. The mufti-layered
