PROCESS FOR PRODUCING LOW CRIMP POLYETHYLENE OXYBENZOATE YARNS

摘要

The present invention relates to a process for producing low crimp polyethylene oxybenzoate (hereinafter designated as PEOB) yarns, and more particularly, multifilament yarns having natural silk-like beautiful appearance and excellent feelings which is characterized by heat treating a PEOB drawn yarn having a beta -value of from 20 to 80 and a shrinkage value in boiling water of from 20 to 35 percent under substantially no tension so as to decrease the beta -value by more than 10.
