Abstract

The dyeing of fibres, fabrics and the like of polyacrylonitriles and copolymers of monomers containing at least 80 per cent of acrylonitrile is facilitated by treating the fibres and the like with N,N-dimethylformamide or N,N-dimethyl-acetamide before or during dyeing. Diluents such as water, acetone and dioxane may be present. In examples: (1) and (2) a fabric of a copolymer of 97 per cent acrylonitrile and 3 per cent vinyl acetate is immersed in N,N-dimethylacetamide or N,N-dimethylformamide at 60 DEG C., washed and dyed with Acid Green CC; and (3) a similar knitted fabric is simultaneously treated and dyed with a solution in N,N-dimethylacetamide of the dyestuff Acid Green CC.
