A technical article on dyeing acetate silk, explaining how its acetylated cellulose chemistry differs from regenerated cellulose rayons and why it needs special dyes and low-temperature, non-alkaline baths. It covers cleaning, preliminary washing, bleaching (permanganate and hypochlorite processes), and the main acetate dye classes (Celloxane/mordant with basic dyes, Cellit Fast, Celliton and Celliton Fast, Cellitazols), with recipes and temperatures. It also describes dyeing mixed fabrics of acetate with cotton, viscose, wool and real silk, including multi-colour effects, and notes on finishing and care.
