<p>Crimpable, drawn, heat relaxed nylon filament yarns consists of longitudinally bonded eccentric components of a crystalline homopolyamide, and a randomly arranged fibrous copolymer which contains at least 20% wt. Polyhexamethyleneadipamide groups, and at least 20% wt. of other polymer units, as in Neth. 281,914. The improvement comprises utilising as the other polymer unit, at least two components chosen from polyhexamethylenesebacamide, polyhexamethyledodecanamide, polyhexamethyleneundecanamide, and polyhexamethylene-isophthalamide.</p> |
