DYEING AND FINISHING OF MODAL FABRICS

摘要

A modal fabric is given a clean, soft-touch surface finish by impregnating the fabric with an acid or acid donor such as magnesium chloride, heat-treating the impregnated fabric in a gaseous atmosphere to activate the acid or acid donor and subsequently dyeing, washing and drying the fabric using vigorous conditions such as jet dyeing or rotary tumbling. The process is used to give fabrics made from high wet-modulus modal or polynosic fibres a clean, soft -touch finish, preferably a peach-touch finish.
