DYEING AND FINISHING OF LYOCELL FABRICS

摘要

A dyed and finished lyocell fabric having a clean, soft­ touch finish is produced by a process in which the fabric is impregnated with a solution of a mixture of a multi-functional carboxylic acid and a Lewis acid before being heat-treated in a gaseous atmosphere at from 600C to below 120°C. This allows the primary fibrillation induced by a wet processing treatment using mechanical action to be easily removed so that a subsequent tumbling operation develops a clean, soft-touch finish.
