    • After a polyester tow having a total denier of 5000 de is drafted at a ratio of between 10 and 20 and stretch broken, the obtained fiber bundle of staple fibers is subjected to a false twisting operation by means of a fluid jet nozzle, and then the false twisted fiber bundle is wound several turns around a hot roller heated at a temperature of 220.degree. C. and located in a detwisting region downstream from the false twisting nozzle. The surface fibers, which extend outwards because of the centrifugal force generated by the rotation of the fiber bundle during the detwisting thereof, suddenly stopped rotation when the fiber bundle contacts the hot roller, and the surface fibers wrap around the body portion of the fiber bundle to form a plurality of individual wrapping portions, in each of which the surface fibers are interlaced each other. Thus a spun-like yarn is obtained.
    • 在总旦数为5000detex的聚酯丝束以10至20的比例拉伸并拉伸断裂后,所得的短纤维纤维束通过流体喷嘴进行假捻操作,然后 假捻扭曲纤维束围绕加热到220℃的热辊卷绕数圈,并且位于假捻嘴下游的下降区域中。 由于纤维束在其转动期间由于旋转而产生的离心力而向外延伸的表面纤维在纤维束接触热辊时突然停止旋转,并且表面纤维缠绕在纤维束的主体部分 以形成多个单独的包裹部分,其中每个包裹部分中的表面纤维彼此交织。 由此得到纺丝纱。
