Abstract (en)

[origin: WO9940251A1] A method for dyeing and finishing a lyocell fabric or polynosic fabric includes the steps of dyeing the fabric with a reactive dyestuff under conditions such that primary fibrils are formed; removing the primary fibrils from the fabric by treatment with a solution of a cellulase; heating the solution to both denature the cellulase and induce secondary fibrillation; and drying the fabric. The method offers the advantages of low liquor usage and shortp rocessing time.
