## 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.

## Claims

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.

### Claim 2 (depends on 1)
