Abstract

A filament having a longitudinally extending "sharp-edge configuration", i.e. a configuration such that a cross-section of the filament has a point formed by the intersection at an angle of at most 90 degrees of two straight or curved edges is produced by spinning through one spinneret orifice a composite filament having at least two components of different polymeric materials (and, optionally, cross-section and/or denier) spun so as to adhere to each other and to extend over the entire length of the filament. At least one component has the specified configuration and in a yarn formed of the composite filaments, this component or components, for example, by mechanical action or dissolving the latter by means of a preferential solvent. The sharp-edged filament may be a polyester. The yarn may be crimped by differential shrinkage of component filaments when heated.
