Abstract

Cellulase was applied to pretreat cotton yarn-dyed fabric in super soft finish.By single-factor experiment of cellulase treatment with concentration,temperature,treating time and pH value,the bending rigidity and the bending hysteretic moment were tested to evaluate the soft effect.Influence of cellulase treatment on breaking tenacity,breaking elongation rate and wettability of fabric was analyzed.It was shown that cellulase pretreatment conferred better pliancy to fabric and other physical performances were also improved,under the condition of cellulase concentration 2.5%(owf),pH value 4.5,liquor ratio 1∶20,treating at 40 ℃ for 60 min.
