Abstract
A process for producing woven fabrics which includes the steps of i) producing a stabilized size-free flat multifilament yarn, ii) forming a warp form the flat multifilament yarn of step i), III) leasing the warp formed in step ii) into the heddles of the shafts and into the reed of a weaving machine, and iv) producing a woven fabric through the insertion of warp threads in the transverse direction to the coarse of the warp at a weft insertion frequency of at least 300 picks/minute. The tension on the stabilized and size-free flat multifilament yarn does not exceed 1.0 cN/dtex. Also described is a woven fabric having warp threads based on stabilized flat multifilament yarns woven without size, whose warp thread density is more than 30 ends/cm and whose weft thread density is at least 30 picks/cm.
