    摘要： While being fed into a laterally confining region to be retained temporarily and compressively crimped therein, laterally spaced textile strands are traversed laterally to and fro along the entrance to the region. The resulting uneven cross-sectional distribution of crimped strand accumulation in the region is conducive to separation of individual strands upon exiting from the region.

    摘要： A process for producing polyester filaments having high Young''s modulus and excellent crimps, which comprises heat-treating a bundle of drawn filaments of linear polyester in which at least 85 mole percent of the recurring units consist of ethylene terephthalate, at a temperature of 135* to 240*C. under a tension of at least 0.3 g/denier, feeding the filaments to the nip rollers of a stuffer box while maintaining the filaments at a temperature at least 10*C. lower than the heat-treating temperature and between 100* and 140*C. under a tension of at least 0.1 g/denier, crimping the filaments in the stuffer box, and then with-drawing the filaments from the stuffer box.
