CRIMPABLE COMPOSITE POLYAMIDE YARN

摘要

A crimpable bicomponent filament in which one component is a polyamide and the other a random copolyamide containing specified percentages of three polymeric units. The different units and their concentrations are 70-82 percent hexamethylene adipamide, 13-25 percent caproamide and 5-17 percent hexamethylene dodecanedioamide. Yarns of one or more such filaments are particularly useful in the manufacture of hosiery because of their high crimpability, high strength and low shrinkage in the fabric.
