ABSTRACT:
Flame resistance of polyamide materials, notably wool and other keratinous materials, is enhanced by application of tungsten from acid solutions of anionic tungsten complexes. Still more effective treatment is obtained by simultaneously applying anionic complexes of zirconium or titanium. The complexes can be applied by exhaustion from a bath, preferably below pH 3.5 and at temperatures from 30.degree. to 100.degree.C. Dyes can be simultaneously applied from the same bath. Textiles can be padded in the solution and dried. The complexes may be isopolytungstates or heteropolytungstates and may be prepared with the help of organic carboxylic or hydroxycarboxylic acids.
