a) The treatment of cellulosic textiles, in yarn or fabric form, with a concentrated solution of a caustic alkali whereby the fibres are swollen, their strength and dye affinity is increased and their handle (q.v.) is modified.
Stretching the swollen materials while wet with caustic alkali and then washing the alkali has the additional effect of enhancing the lustre (q.v.)
b) The process of steeping cellulose in a concentrated caustic soda solution.
The treatment of cellulosic fabric with caustic to improve dye-ability and handle.
The treatment of cellulosic textiles in yam or fabric form with a concentrated solution of caustic alkali whereby the fibres are swollen, the strength and dye affinity of the materials are increased, and the handle is modified.
A treatment of yarns or fabrics with caustic alkali, in which fibres are swollen and stretched to increase lustre in the finished product.
