Abstract

PURPOSE:To prevent the occurrence of yarn breakage even in spinning at a high speed and carry out the spinning at improved operating ratio, by spinning yarns while feeding a spun yarn or filament yarn of fibers soluble in hot water to front rolls of a main draft zone. CONSTITUTION:A fiber bundle 1 constituted to one or more short fibers is predrafted by back rolls 4 and 4' and front rolls 5 and 5' of a predrafting zone 2, wetted with water supply from water supply nozzles 6 and 7, squeezed by squeezing rolls 8 and 8' drafted mainly by back rolls 10 and 10' of a main drafting zone 3, false twisted by a false twisting nozzle 14, dried and wound. In the spinning method, a spn yarn or filament yarn 12 of fibers soluble in hot water is fed through a yarn guide 13 to front rolls 11 and 11' of the main drafting zone 3.

くなり。The present invention has the above-mentioned configuration. That is, spun yarn or filament yarn made of hot water soluble fiber is supplied from the rear of the front roller in the main draft zone during spinning, and the spun yarn or filament yarn made of hot water soluble fiber is supplied to the drafted fiber. After the bundle is combined at the nip point of the front roller, it is pulled out while being false-twisted, so it is suitable for high-speed spinning with a culm of 200 m/min, and even more so when spinning at a high-speed pulling speed of 400 m/min or more. Even at °C, the fibers no longer wrap around the front roller as they did in the past.
