    摘要: The present invention relates to a process for continuous dyeing of filaments based on atactic polyvinyl chloride in the course of production.It comprises, in succession, the phases of drawing, impregnation of the filaments by padding while, at the time of the impregnation, the filaments have a density of between 1.3 and 1.4 g/cm.sup.3 (the filament roving having a water content of 10 to 30% by weight), of stabilization under tension in the presence of steam under pressure at a temperature between 100.degree. and 130.degree. C. for 2 to 20 seconds, and then oiling and shrinking in a known manner.Dyeing carried out in this manner is quick and makes it possible to produce colors having good fastness.

    摘要: Basic azo dyes are made by coupling an appropriate diazotized benzenoid or heterocyclic base with an N-dialkylaminoalkylene ( Alpha (N-alkylanilino))m- or p-toluenesulfonamide. Quarternization of the pendant dialkylamino group in the coupler may be carried out before or after coupling if desired to yield quaternary structures. The unquaternized structures, when properly dispersed, are applied to polyesters with excellent substantivity, outstanding fastness to sublimation and good fastness to light. The disperse unquaternized dyes are applied to polyacrylonitrile fabrics from a neutral or acidic bath; the water soluble quaternary structures are especially useful for coloring acrylic fibers.
