DYEING AND FINISHING OF LYOCELL FABRICS

WIPO Patent Application WO2002103104

A3

A process for producing a dyed and finished lyocell fabric having a clean, soft-touch finish by carrying out the steps of dyeing, washing and drying a lyocell fabric using vigorous action such as by jet dyeing or rotary tumbling on the fabric in at least one of the steps so as to produce fibrillation on the surface of the fabric, is characterised in that, before the dyeing step is carried out, the fabric is evenly impregnated with an aqueous solution of an acid or acid donor and is then heat treated in a gaseous atmosphere to activate the action of the acid or acid donor. The dyed and finished fabric has a clean, soft-touch finish substantially free from visible crease marks normally produced on lyocell fabrics which have been subjected to vigorous action in dyeing and/or finishing.
