Abstract
A process for the treatment of natural and/or synthetic fibrous and filamentary materials, including living human hair, which involves applying to the fibrous or filamentary materials a polymeric compound containing at least one poly (oxyalkylene) or polyamide chain and at least one thiosulphuric acid or thiosulphate group. Such compounds having more than one thiosulphuric acid or thiosulphate group are curable and can be used with advantage in textile finishing, for example in the pigment dyeing and printing of fibrous materials including pure synthetic fibres, in application to fibres or fabrics to impart shape stabilisation, in application to keratinous fabrics to impart shrink resist properties and for the flat setting and permanent creasing of fabrics, and to impart antistatic properties to fibres and filaments. Hair may be treated according to the invention to improve its handle and for permanent waving and setting.
