Abstract
Silk woven fabric is known and renowned for its touch. The drawback of silk, however, is its price, its poor washability, and low resistance against certain chemical treatments. It is therefore the object of the invention to provide a silk-like woven fabric which overcomes these problems. According to the invention, this problem is solved by providing a silk-like woven fabric (2) made from weft yarns (4) and warp yarns (6), wherein at least one of the weft yarns (4) and the warp yarns (6) contains or consists of lyocell filaments (8). Especially twisted lyocell filament yarns are used, the resulting material has a touch comparable to silk and physical properties that are equal to or even surpass those of silk. Moreover, the lyocell filament yarns (4, 6) may have a higher twist than silk yarns, other cellulose yarns, or synthetic yarns.
