Yarn for formable sheet structures and process for preparing the yarn

摘要

Textured yarns which can be processed for example by deep-drawing into irreversibly highly formable woven or knitted fabrics and a process for their preparation are described. These yarns have degrees of elasticity of below 50% and contain at least as carrier component undrawn but partially oriented polyester filaments which have been improved by a heat treatment in their flow stress.
