Process for the production of high strength yarns by spin- stretching and yarns produced by the process, especially from polyamide-6 and polyester filaments

摘要

An improved process for the spin-drawing of high-tenacity, technical- grade yarns is disclosed. The process produces yarns of high industrial quality having a low break elongation and low reference elongation, or a low heat shrinkage and low reference elongation. The process is especially suitable for yarns of polyamide and polyester.
