Abstract

A process is described for making three-dimensionally crimped fibers and filaments from synthetic high-polymers. Fibers and filaments with a double refraction gradient over their cross-sectional area, which have been obtained by known methods, are drawn and subsequently dried at temperatures within the range of from 50 DEG to 230 DEG C without any shrinkage. After drying, the crimp is developed at temperatures within the range of from 60 DEG to 230 DEG C with the filaments being free from any tension.
