Abstract
The invention concerns a crimped Polyester-yarn obtained from cold drawn Polyester-POY as well as a process for its manufacture. For this yarn the stress/strain course between 10 and 30% elongation resulting from the stretch test corresponds to a secant modul of 0-100%. Application in the knitting, weaving and warp knitting.
Claims5
Crimped polyester yarn obtained from cold drawn partially-oriented polyester yarn, said crimped polyester yarn having a secant modulus of 0-100% as determined by the stress versus strain curve for said crimped polyester yarn between 10% and 30% elongation.
