Abstract
A novel process for producing yarns at high speed by drafting a sliver or roving of short fibers. The process dispenses with rings, travellers or spindles, and a single gas false twist member is effectively used. The process comprises leading a bundle of short fibers to said false twist member and feeding to the twisting zone of the bundle of short fibers an extremely fine multifilament yarn preferably in contact over a rotary body, at a sufficiently low tension and at a speed faster by 50-90% than the spinning speed of the bundle of short fibers so as to restrain the fiber bundle within one-directional spirals and two-directional composite spirals. The resulting composite spun yarn has a good touch because the fiber bundle has become non-twisted. By changing production conditions, the yarn can be formed into any desired shape from even yarn to nep yarn.
