ABSTRACT:
Fibers substantially consisting of a blend of aromatic polyamides comprising poly-p-phenylene terephthalamide and up to 50 wt. % of a second polyamide of related structure containing diaminobenzanilide units.
The second polyamide should provide at least 0,1 wt. % of diaminobenzanilide units in the blend and is derived from aromatic monomers selected from the group comprising terephthalic acid, 4,4'-diamino benzanilide, p-phenylene diamine and p-amino benzoic acid. The fibers possess an elastic behavior particularly useful for tire yarn purposes.
