Process for dyeing and finishing of cellulosic genres.

摘要

Process for dyeing and finishing a lyocell fabric or a polynosic genus, comprising the steps of: (1) applying to the genus shaped string a liquor containing in solution a reagent for cellulose dye under conditions such that ( i) a high degree of dye exhaustion on gender is achieved and (ii) fibrillation of the genus occurs, thereby providing a dyed fabric exhibiting primary fibrillation; (2) applying to the genus as a line, with no more than a single intermediate rinse a solution of a cellulase and maintaining the solution in contact with the fabric under conditions effective to remove primary same fibrils by the action of the cellulase, thereby providing a dyed fabric exhibiting a low degree of fibrillation; (3) raising the temperature of the solution while keeping in contact with the fabric, whereby (i) the cellulase is denatured and (ii) secondary fibrillation is induced in the genre, thereby providing a dyed fabric exhibiting secondary fibrillation ; and (4) drying the genre.
