13,132. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. June 6. Dyeing.-Bi- and multi-coloured effects are produced on fabrics composed of cotton and wool, by protecting the wool from the action of sulphide dye-stuffs by treating it with formaldehyde and a suitable chromium compound either before or after weaving or spinning, and then dyeing the mixed fabric with sulphide colours in a suitable bath, preferably one containing the sulphide dye, sodium sulphide, and salts of those organic acids that possess a reducing-action, for example formic acid or lactic acid. The wool may be dyed with a suitable dye-stuff either before or after the formaldehyde and chromium treatment, and either before or after weaving with cotton.
