Abstract

PURPOSE:To carry out stable spinning operation in high operability, without causing too much neps and end breakages even in a high-speed spinning, by using a rubber roller having the surface finished to a specific roughness as a front top roller of the main draft zone in a wet spinning process. CONSTITUTION:A silver or roving 1 consisting of one or plural kinds of fibers is predrafted in the predraft zone 2, moistened with water supplied e.g. through the feed nozzles 6, 7, squeezed with the squeezing rollers 8, 8', subjected to the main drafting in the main draft zone 3 and the false twisting by the false twist nozzle 12, dried, and wound. In the above wet spinning process, a rubber roller having a surface roughness of 0.8-50S is used as the front top rollers 11, 11' of the main draft zone 3.
