Abstract: Spinnable compositions for yarn manufacture consist of (a) a fibre-forming polyamide, (b) up to 50% wt. fibre-forming polyester dispersed in (a), and (c) 0.05-0.6% wt. saturated acyl compd. having a C12-22 straight carbon chain, and a m.p. of more than 100 deg.C, as spinning assistant. Compd. (c) is pref. an alkali or alkaline earth metal salt of an aliphatic carboxylic acid. Sodium stearate, sodium palmitate or calcium stearate are particularly pref. as spinning assistants. Addn. of compd. (c) gives spinnable compositions for yarn prodn. baving a reduced tendency to block the orifices in the spinning plate. The composition is suitably based on mixtures of polyethylene terephthalate with polycaprolactam and/or polyhexamethyleneadipamide.
