Abstract

1,196,275. Multifilamentary yarns of composite filaments. CHEMIEFASERWERK SCHWARZA WILHELM PIECK. 18 Aug., 1967, No. 38070/67. Heading B5B. Multifilamentary yarns the individual filaments of which are of the composite type having crimp potential and which are bulky or voluminous when heated to cause the individual filaments to crimp are produced by spinning different synthetic high polymer components having different shrinkage properties through spinnerets having separate supply chambers for the individual components, said components being united without substantial mixing, either immediately in front of the spinneret face, or within the spinneret orifices or within the inlet ducts of the orifices, whereby there is obtained a multifilamentary yarn, the individual filaments of which are composite and have a circular or a profiled cross-section, the individual filaments differing from one another in the shapes of their cross-sections and/or in the ratios of the areas of their cross-sections corresponding to their components and/or the distribution of these areas, these characteristics remaining constant over the total length of each individual filament. The filaments are preferably bicomponent filaments and the polymers used may be polyamides or polyesters. In an example, a 30 denier yarn consisting of six individual bicomponent conjugated filaments of circular cross-section is produced by simultaneously extruding through each of the six orifices of a spinneret adapted for the spinning of conjugate filaments a molten polycaproamide and a copolymer consisting of 80% polycaproamide and 20% of polyhexamethylene adipamide. The multifilamentary yarns thereby produced are stretched at a stretch ratio of 3À35: 1 and shrunk in water at 100‹ C. for 10 minutes, producing a crimp contraction of 40%.
