Abstract

The invention relates to a woven fabric comprising a weft yarn and at most two warp yarns A and B, wherein the weft yarn comprises a high performance fiber; the warp yarn A comprises at least 50 wt % of a natural fiber; the warp yarn B comprises a high performance fiber; and wherein the fabric has an outside layer comprising the warp yarn A and an inside layer comprising the warp yarn B and said outside and inside layers being at least partially interconnected by the weft yarn. The invention also relates to products comprising said woven fabric such as clothing, lining, sport apparel, gloves, curtains, upholstery fabric and floor covering.

First claim

The invention claimed is:

1. A woven fabric comprising:
a weft yarn, and
at most two warp yarns A and B, wherein
the weft yarn comprises a fiber having a tenacity or tensile strength of at least 2.5 N/tex;
the warp yarn A comprises at least 50 wt % of a natural fiber;
the warp yarn B comprises a fiber having a tenacity or tensile strength of at least 2.5 N/tex; and wherein
the fabric has an outside layer comprising the warp yarn A and an inside layer comprising the warp yarn B and said outside and inside layers being at least partially interconnected by the weft yarn.

2. The fabric of claim 1 , wherein the natural fiber is cotton or wool.

3. The fabric of claim 1 , wherein the warp yarn B comprises at least 1 wt % of the fiber having a tenacity or tensile strength of at least 2.5 N/tex.

4. The fabric of claim 1 , wherein the weft yarn comprises at least 10 wt % of the fiber having a tenacity or tensile strength of at least 2.5 N/tex.

5. The fabric of claim 1 , wherein warp yarn A further comprises synthetic fibers of polyamides, polyesters, polytetrafluoroethylene, polyolefins, polyvinyl alcohols and polyacrylonitriles; and/or fibers having a tenacity or tensile strength of at least 2.5 N/tex; and/or other natural fibers than cotton, hemp, wool, silk, jute, linen.

6. The fabric of claim 1 , wherein the fibers having a tenacity or tensile strength of at least 2.5 N/tex of the weft yarn and the warp yarn B are individually at least one selected from the group consisting of aromatic polyamide fibers, liquid crystalline polymer fibers, polybenzimidazoles fibers, polybenzoxazoles fibers, polyarylate fibers, highly oriented polyethylene fibers and highly oriented polypropylene fibers.

7. The fabric of claim 1 , wherein the amount of the fiber having a tenacity or tensile strength of at least 2.5 N/tex in the weft yarn and the warp yarn B is at least 10wt % wherein the wt % is a ratio of cumulative weight of fiber having a tenacity or tensile strength of at least 2.5 N/tex which is present in the weft yarn and warp yarn B to cumulative weight of the weft yarn and the warp yarn B.

8. The fabric of claim 1 , wherein the warp yarn B is a spun yarn.

9. The fabric of claim 1 , wherein the weft yarn is a continuous filament yarn.

10. The fabric of claim 1 , wherein the warp yarn B further comprises at least one fiber selected from the group consisting of cotton fibers, hemp fibers, wool fibers, silk fibers, jute fibers, linen fibers, polyamide fibers, polytetrafluoroethylene fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers and polyacrylonitriles fibers.

11. The fabric of claim 1 , wherein the weft yarn further comprises at least one fiber selected from the group consisting of cotton fibers, hemp fibers, wool fibers, silk fibers, jute fibers, linen fibers, polyamide fibers, polytetrafluoroethylene fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers and polyacrylonitriles fibers.

12. The fabric of claim 1 , wherein the warp yarn B comprises ultrahigh molecular weight (UHMWPE) fibers and the weft yarn comprises aromatic polyamide fibers.

13. The fabric of claim 1 , wherein the warp yarn A consists essentially of cotton, the warp yarn B is a spun yarn consists essentially of ultrahigh molecular weight (UHMWPE) staple fibers and the weft yarn consists essentially of continuous UHMWPE filaments.

14. The fabric of claim 1 , wherein the amount of the fiber having a tenacity or tensile strength of at least 2.5 N/tex in the weft yarn and the warp yarn B is at least 30 wt %.

15. The fabric of claim 1 , wherein the amount of the fiber having a tenacity or tensile strength of at least 2.5 N/tex in the weft yarn and the warp yarn B is at least 50 wt %.

16. The fabric of claim 1 , wherein the amount of the fiber having a tenacity or tensile strength of at least 2.5 N/tex in the weft yarn and the warp yarn B is at least 70 wt %.

17. The fabric of claim 1 , wherein the amount of the fiber having a tenacity or tensile strength of at least 2.5 N/tex in the weft yarn and the warp yarn B is at least 80 wt %.

18. The fabric of claim 1 , wherein the warp yarn B comprises ultrahigh molecular weight (UHMWPE) staple fiber.

19. A product comprising the fabric according to claim 1 , wherein the product is selected from a group consisting of clothing, lining, sport apparel, gloves, curtains, upholstery fabric and floor covering.
