    Abstract: There is disclosed a colored high-tenacity fiber of ultra-high molecular weight polyethylene which is obtainable by spinning a solution of ultra-high molecular weight polyethylene and a dye for coloration to form solvent-containing filaments and drawing the solvent-containing filaments. The colored high-tenacity fiber of ultra-high molecular weight polyethylene has a tensile strength of at least 28 g/d and a tensile modulus of at least 700 g/d. The dye is substantially soluble in the solvent at the melting point of solvent-containing filaments which are obtained by spinning a solution of ultra-high molecular weight polyethylene and the dye is substantially uniformly dispersed in the core portion of the fiber. Also disclosed is a process for producing a colored high-tenacity fiber of ultra-high molecular weight polyethylene.

    Abstract: A process for modifying the dyeability of polyamide polymers is disclosed, the process involving the addition of co-fed polyamide flake of the same type of polyamide as the base polyamide with the co-fed flake having a significant effect on the final dyeability. The additive flake comprises high- or low-amine-end polyamide flake which is mixed and melted with the base polyamide to adjust the total number of amine ends in the polymer, thereby controlling the polymer dyeability.

    Abstract: Shaped articles, such as fibers, formed of a polyamide formed by salt-blending the polyamide precursor salt with a cationic dye modifier, such as the dimethyl ester of 5-sulfoisophthalic acid, followed by polymerization, are rendered resistant to staining by acid dyes at ambient conditions either by adding an acid dye to the polymer melt or by dyeing with an acid dye from an acid dyebath at pH 2 to 7 and 60.degree. to 100.degree. C. so that the shaped article contains from at least 0.0048 and preferably at least 0.0096 wt % of an acid dyestuff. In a preferred aspect of the invention, the shaped articles are oriented, crimped, heat-set fibers for use as the facing in carpets.

    Abstract: The invention relates to a process for spin dyeing polymers of acrylonitrile or copolymers containing predominantly acrylonitrile, which process comprises adding to the spinning solution a monocationic dye salt of the formula ##STR1## wherein D is the group of atoms necessary to close a 5-membered heterocyclic ring containing two N-atoms, or to close a 6-membered heterocyclic ring, which rings may optionally contain fused benzene rings, or is the group of atoms necessary to close a benzthiazole ring, and Q is the radical of a carbocyclic or heterocyclic aromatic coupling component, and R.sub.1 is alkyl, aralkyl or aryl. The yellowish-red transparent fibres obtained have excellent fastness properties.
