Abstract

1,095,147. Crimped heterofilaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 9, 1965 [June 9, 1964], No. 23782/64. Heading B5B. Heterofilaments comprise at least two adherent polymeric components of which at least one is an elastomer and at least one other component is a non-elastomer, which heterofilaments crimp spontaneously after drawing. The components may exist in sheath-core or a side-by-side relationship. The filaments after having been drawn may have a crimp frequency of at least 10 crimps per inch and a helix diameter of less than 1 mm. The crimp in these filaments may have been developed by drawing them by an amount which exceeds the amount by which the elastomeric component may be permanently elongated by at least 20% and preferably at least 50%. The heterofilaments may be formed by melt spinning, the components being simultaneously extruded through the same or different extrusion orifices. The non-elastomeric component may be a polyamide such as poly hexamethylene adipamide, poly epsilon caprolactam or poly (11 amino undecanoic acid), a polyester such as polyethylene terephthalate or a crystalline polyolefine such as polyethylene or polypropylene. The elastomeric component may be an N-substituted polyamide prepared from a lactam of an amino-carboxylic acid and an N-substituted amino-carboxylic acid containing more than 7 carbon atoms, or a polyester urethane.
