Abstract

Cellulose acetate goods are dyed with vat or sulphur dyes in hydrosulphite vats kept weakly alkaline by ammonia, only sufficient caustic alkali being present to form the leuco-compound; preferably salts such as barium, calcium, or magnesium chloride, and protective colloids such as boiled-off liquor, gelatine, glucose, or starch, are added to the vats. Examples are given of dyeing with Bromindigo and Pyrogenindigo. Specification 182,830 is referred to.
