Abstract

A product comprising a plurality of interlaced yarns wherein at least a first yarn having a tensile strength, having a value TS in N/tex, said first yarn containing a plurality of UHMWPE fibers having a titer, having a value T in den, wherein the ratio T/TS is at least 5 den.tex/N. The tensile strength is obtained by adjusting the drawing ratio or the UHMWPE filaments/fibers accordingly. The product shows resistance to abrasion. The product can be a rope or round slings, comprising a sheath/jacket comprising said first yarn.

First claim

The invention claimed is:

1. An abrasion resistant product comprising a plurality of interlaced yarns wherein at least a first yarn has a tensile strength, having a value TS in N/tex, the first yarn containing a plurality of UHMWPE fibres with a titer per fiber, having a value T in den, and wherein a ratio T/TS is at least 6 den.tex/N.

2. The product of claim 1 , wherein the plurality of UHMWPE fibres have a titer of at least 6 den.

3. The product of claim 1 , wherein the first yarn has a tensile strength in the range of 0.5 to 2.2 N/te.

4. The product of claim 1 , further comprising a second yarn containing a plurality of high performance fibers, wherein the second yarn is different from the first yarn.

5. The product of claim 4 , wherein the second yarn has a tensile strength of at least 2.2 N/tex.

6. The product according to claim 1 , wherein the plurality of interlaced yarns are braided, knitted, woven or any combination thereof.

7. The product of claim 1 , wherein the product is selected from the group consisting of fabrics, ropes, nets, slings and belts.

8. The product of claim 1 , further comprising a sheath section and a core section, wherein the sheath section comprises the first yarn.

9. The product of claim 8 , wherein the sheath section is a fabric.

10. The product of claim 7 , wherein the core section is a rope-like construction comprising the second yarn.

11. The product of claim 6 , wherein the product is a rope or a round sling comprising an abrasion resistance sheath section comprising the first yarn.

12. The product of claim 1 , wherein the ratio T/TS is at least 7 den.tex/N.

13. The product of claim 1 , wherein the ratio T/TS is at least 8 den.tex/N.

14. The product of claim 2 , wherein the titer of the plurality of UHMWPE fibres is at least 9 den.

15. The product of claim 2 , wherein the titer of the plurality of UHMWPE fibres is at least 11 den.

16. The product of claim 2 , wherein the titer of the plurality of UHMWPE fibres is at least 14 den.

17. The product of claim 3 , wherein the tensile strength of the first yarn is in the range of 0.8 to 2.0 N/tex.

18. The product of claim 3 , wherein the tensile strength of the first yarn is in the range of 1.0 to 1.8 N/tex.

19. The product of claim 5 , wherein the tensile strength of the second yarn is at least 2.4 N/tex.

20. The product of claim 5 , wherein the tensile strength of the second yarn is at least 2.7 N/tex.

21. The product of claim 5 , wherein the tensile strength of the second yarn is at least 3.0 N/tex.

22. The product of claim 9 , wherein the sheath section is a woven or braided fabric.

23. The product of claim 9 , wherein the sheath section is a hollow woven fabric.

24. An abrasion resistant product comprising a plurality of interlaced yarns, wherein at least a first yarn has a tensile strength, having a value TS in N/tex which is in a range of 0.5 to 2.2 N/tex, the first yarn containing a plurality of UHMWPE fibers with a titer per fiber, having a value T in den, and wherein a ratio T/TS is at least 5 den.tex/N.

25. The product of claim 24 , wherein the ratio T/TS is at least 7 den.tex/N.

26. The product of claim 24 , wherein the ratio T/TS is at least 8 den.tex/N.

27. The product of claim 24 , wherein the tensile strength of the first yarn is in the range of 0.8 to 2.0 N/tex.

28. The product of claim 24 , wherein the tensile strength of the first yarn is in the range of 1.0 to 1.8 N/tex.

29. The product of claim 24 , further comprising a second yarn containing a plurality of high performance fibers, wherein the second yarn is different from the first yarn.

30. The product of claim 29 , wherein the second yarn has a tensile strength of at least 2.2 N/tex.

31. The product of claim 29 , wherein the tensile strength of the second yarn is at least 2.4 N/tex.

32. The product of claim 29 , wherein the tensile strength of the second yarn is at least 2.7 N/tex.
