Abstract: A solid mixture contains as essential components (A) from 40 to 99% by weight, based on the total weight of (A) and (B), of a nonnucleating thermoplastic polyamide and (B) from 1 to 60% by weight, based on the total weight of (A) and (B), of a thermoplastic polyamide which contains a nucleating agent, and in addition (C) from 0 to 60% by weight, based on the total weight of (A)+(B)+(C), of fibrous or particulate fillers.

Abstract: Filaments with a relative viscosity RV of 2.0 to 3.0 (measured at a concentration of 1 g of fibres per 100 ml in a 96 wt % sulphuric acid) based on polycaprolactam, obtainable by: (a) extruding a melt consisting essentially of caprolactam through a spinning nozzle to form caprolactam filaments; (b) cooling the filaments thus produced and (c) drawing the cooled filaments off at a rate of at least [3600 + 1250.(3.0 - RV)] m/min, the polycaprolactam used being produced in the presence of at least one bicarboxylic acid from the group: C4-C10-alkane bicarboxylic acids, C5-C8-cycloalkane bicarboxylic acids, benzole and naphthaline bicarboxylic acids which may have up to two sulphonic acid groups and whose carboxylic acid groups are not adjacent, N-C1-C6-alkyl-N,N-di(C4-C10-alkane carboxylic acid)amine, 1,4-piperazine-di(C1-C10-alkane carboxylic acid), and a process for producing these filaments, their use for the production of fibers and flat products, and fibres and flat products made of these filaments.
