Abstract

Filaments formed from an acrylonitrile polymer which contains, by weight in the molecule, at least 75 per cent. of acrylonitrile (including two-component copolymers, ternary polymers and blends of an acrylonitrile polymer with other polymers), and which have been freed of residual spinning solvent or do not contain more than 5 per cent. thereof, are crimped and stabilized by continuously passing a bundle or tow of filaments first through a zone in which the filaments are heated and stretched at least 100 per cent. and then through a crimping zone in a packed condition, the filaments being continuously heated to a temperature below the melting point of the polymer and above the temperature at which the filaments tend to shrink, immediately prior to their introduction into the crimping zone, whereby the filaments are internally relaxed and stabilized in the crimped condition. For example, the tow may be heated to at least 100 DEG C. to reduce the residual shrinkage capacity of the filaments to not less than 3 per cent. at 100 DEG C. In an example, a tow of continuous filaments formed from a dimethylacetamide solution of a copolymer containing, in the molecule, 97 per cent. of acrylonitrile and 3 per cent. of vinyl acetate, having a total denier of 34,000 and containing about 2 per cent of dimethylacetamide by weight, is passed between canted godets and through an intermediate stretching tube into which steam under 120 lbs./sq. in. pressure is introduced, the tow being stretched 320 per cent.; it is then stuffed into a crimping chamber (see Group IX) and subjected therein to the action of dry steam at a pressure of 1 lb./sq. in. for approximately 15 seconds, the emerging filaments being free from internal strains and having a residual shrinkage capacity of about 2 per cent. at 100 DEG C.
