Abstract

1,096,249. Composite crimpable polyamide filaments. SOCIETE DE LA VISCOSE SUISSE. Nov. 24, 1965 [Nov. 24, 1964], No. 49930/65. Addition to 969,110. Heading B5B. The process of Specification 969,110 for the manufacture of crimped or voluminous yarns containing composite filament (wherein yarns containing composite filaments of polyamides of uniform composition are produced by melt spinning, the double refractions of the filament components in the unstretched state differing by at least 0À002, the yarns are stretched at at least 60‹ C. and the tension on the yarns subsequently relaxed to allow the spontaneous crimp of the composite filaments to develop) is modified in that the filaments are bi-component filaments and the two components thereof are melt-spun through three-armed spinneret orifices to provide trilobal filaments in the yarn. The centres of the orifices may be vertically below the straight edge along which the two components unite, the slots of the orifices and the angles included therebetween being arranged symmetrically about said edge as a line of symmetry. One of the components may have a lower reduced viscosity than the other and cooling air may be blown on to the composite filament from a direction faced by one of the slots of each orifice, the component of lower reduced viscosity flowing through the slot that faces the stream of cooling air. The component of lower viscosity may flow through a slot of each orifice which is of different length of the other two slots, said other two slots being of equal lengths. The crimped filaments may be heat-set in the slack state.
