WOVEN STRETCH FABRIC AND METHOD FOR ITS PRODUCTION

摘要

A woven fabric has weft and warp yarns, the weft yarns are extending over and below the warp yarns to provide correspondent over portions and under portions with respect to the warp yarns, whereby the ratio length of under portions:length of over portions is such that in the washed fabric the warp yarns corresponding to the over portions are in a position that is lower than the plane of the warp yarns corresponding to the under portions; the final fabric, after washing, has an elongation measured according to ASTM 3107, of at least 30%.

1. A woven fabric (1) having weft yarns (3) and warp yarns (2, 2FS,2BS), wherein said fabric has a front side (FS) and a back side (BS), and at least 50%, preferably at least 80%, of the weft yarns (3) are elastic, said weft and warp yarns being woven together in a weaving pattern whereby the weft yarns (3) are extending over a number of warp yarns (2BS) and below a number of warp yarns (2FS) to provide weft over portions (5) in said front side and weft under portions (4, 4′) in said back side (BS), characterized in that the warp yarns (2BS) corresponding to said over portions (5) of the weft yarn are biased by said elastic weft yarn (3) in a position that is lower than the plane of the warp yarns (2FS) corresponding to the under portions (4, 4′) of the weft yarn (3), and wherein the fabric has an elongation measured according to ASTM 3107, of at least 30%.
