A process of treating textile fabrics for rendering them less liable to creasing andresistant to crumpling

摘要

Fabrics are rendered crease resisting by first sizing the fabric so that the fibres are individually coated with a film of latex, rubber, rubber derivative, siccative or vulcanized oils and then with synthetic and/or natural resins. The first treatment is preferably with an aqueous rubber dispersion, which may contain vulcanizing substances and dispersing media; solutions of rubber in solvents such as benzol and toluol may be used. Vulcanizing may be effected before or after the resin treatment. In an example, a fabric is impregnated with a 40 per cent solution of latex containing some alkylated naphthalene sulphonic acid as a dispersing agent, dried, treated in a solution containing urea, formaldehyde and lactic acid as catalyst, dried and heated to 150 DEG C.
