ABSTRACT:
Dimensionally stable fibers are produced from copolymers prepared from substantially equimolar amounts of hexamethylene diamine and a 50:50 to 80:20 mixture of terephthalic and isophthalic acids by heating essentially amorphous fibers melt spun from the copolymers to a temperature between about 160.degree. C. and 300.degree. C. for a short period of time. The dimensionally stable fibers combine many of the best properties of nylon 66 and poly(ethylene terephthalate) and are particularly useful in tire and textile applications.
