Abstract

A textile material for use in connection with a carrier includes a non-woven fibrous layer which has an irregular surface, and a plurality of separate, round, fiber aggregates, each composed of substantially spherically intermingled fibers. A multiplicity of connecting fibers connects the fiber aggregates to one another.

Claims

1. A textile material comprising a non-woven fibrous layer having an irregular surface formed by needle bonding a plurality of separate fiber aggregates, each aggregate having, prior to needle bonding, a substantially spherical to elongated shape with a smallest diameter of no less than 3 mm, said aggregate is formed from intertwined fibers which include fibers having a length of at least 15 mm, said aggregate also having a density ranging from about 0.01 to about 0.1 grams per cubic centimeter, the intertwining being such that a needle commonly used in needle processing technology to stitch material together may penetrate said aggregate and grip and withdraw a fiber from said aggregate free from encountering any substantial resistance by the aggregate so that the withdrawn length of fiber extends out of the aggregate without losing its cohesion with the aggregate;

and a multiplicity of needle processed connecting fibers interconnecting said fiber aggregates to form said non-woven fibrous layer.

2. A textile material, as claimed in claim 1, wherein said fiber aggregates are actively needle processed by said connecting fibers being passed therethrough.

3. A textile material, as claimed in claim 1, wherein said fiber aggregates are passively needle-processed by said connecting fibers being passed therethrough.

4. A textile material, as claimed in claim 1, wherein said fibrous layer has a predetermined depth, and each fiber aggregate has a prearranged thickness substantially corresponding to said predetermined depth.

5. A textile material as claimed in claim 1, wherein each fiber aggregate is substantially shaped as a sphere.

6. A textile material, as claimed in claim 1, wherein each fiber aggregate is substantially shaped as an ellipsoid.

7. A textile material, as claimed in claim 1 wherein each fiber aggregate is substantially shaped as a cylinder.

8. A textile material, as claimed in claim 1, wherein each fiber aggregate is substantially worm-shaped.

9. A textile material, as claimed in claim 1, wherein said fibrous layer is substantially composed of said fiber aggregates.

10. A textile material, as claimed in claim 1 further comprising a carrier, and wherein said fiber aggregates are connected to said carrier.

11. A textile material, as claimed in claim 10, wherein said carrier is needle-processable.

12. A textile material as claimed in claim 11, wherein said carrier is passively needle-processable, and further comprising a plurality of connecting fibers connecting said fiber aggregates to said carrier.

13. A textile material, as claimed in claim 12, wherein said carrier is a sheet of synthetic material.

14. A textile material, as claimed in claim 12, wherein said carrier is a fabric.

15. A textile material, as claimed in claim 12, wherein said carrier is a netting.

16. A textile material, as claimed in claim 12, wherein said carrier is a paper product.

17. A textile material, as claimed in claim 12, wherein said carrier is a fibrous connecting layer.

18. A textile material, as claimed in claim 10, wherein said carrier includes textile fibers and is actively needle-processable.

19. A textile material, as claimed in claim 1, wherein the fibers of said fiber aggregates are natural fibers.

20. A textile material, as claimed in claim 1, wherein the fibers of said fiber aggregates are synthetic fibers.

21. A textile material, as claimed in claim 1, wherein the fibers of said fiber aggregates include a mixture of natural and synthetic fibers.

22. A textile material, as claimed in claim 20, wherein said fibers are curled.

23. A textile material, as claimed in claim 1, further comprising a covering layer connected to said fibrous layer.

24. A textile material, as claimed in claim 23, wherein said covering layer is needle-processable.

25. A textile material, as claimed in claim 23, wherein said covering layer includes textile fibers.

26. A textile material, as claimed in claim 1, wherein said intertwined fibers have each a length of at least 15 mm.

27. A textile material, as claimed in claim 26, wherein said length is from about 40 mm, to about 120 mm.

28. A textile material, as claimed in claim 1, wherein said connecting fibers are connected to said fiber aggregates by stitching.

29. A textile material, as claimed in claim 1, wherein said connecting fibers are connected to said fiber aggregates by knitting.

30. A textile material, as claimed in claim 1, wherein said connecting fibers are connected to said fiber aggregates by crocheting.

31. A textile material, as claimed in claim 1, wherein said fibrous layer includes a mixture of said fiber aggregates and fibrous material of a shape different from the shape of said fiber aggregates.

32. A textile material as claimed in claim 1, wherein the fibrous layer comprises fiber aggregates which are interconnected by fibers taken from said fiber aggregates.

33. A textile material as claimed in claim 10, wherein said fiber aggregates are connected to said carrier by fibers taken from said fiber aggregates.

34. A textile material as claimed in claim 1, wherein the fibrous layer consists only of fiber aggregates which are interconnected by fibers taken from said fiber aggregates.
