Treatment by Enzyme of the Liquid Ammonia-pretreated Cellulosic Fabrics - Weight Loss and Dyeing Properties -

Cotton and cellulosic other fabrics, such as rayon, polynosic, and linen were treated with liquid ammonia, and then were treated with cellulase after or before dyeing, as well as in the presence of dye. Dyeing was carried out with C. I. Direct Blue 1 at 5$0^{\circ}C$, for 6hr in the case of rayon, and 24hr in the case of cotton, polynosic, and linen. The optimum condition of cellulase was at 55$^{\circ}C$, pH 4~5. Weight loss of fabrics were increased by the liquid ammonia treatment and it was predominant when they were treated with cellulase alone and in the presence of dye. Changes of color strength of the cotton, polynosic, and linen were increased by liquid ammonia treatment compare with untreatment. Especially, in the presence of dye, K/S value of the liquid ammonia-treated fabrics were nearly the smae as untreated.
