Effect of alkali pre-treatment on hydrolysis of regenerated cellulose fibers (part 1: viscose) by cellulases

摘要: Viscose fabrics were pre-treated with liquid ammonia and NaOH solutions. The pre-treatment was varied in alkali concentration, time drying conditions. Subsequently, the samples subjected to cellulase hydrolysis. Microscope SEM pictures taken; weight loss, reducing sugar protein content solution, water retention value tensile strength determined. It found, that activity of cellulases is increased for viscose short reduces due changes substrate. conditions (wet, line dry freeze dry) have great impact on hydrolysis rate. A connection between rate loss solution changed established. Weight 80% cellulose fabric achieved within 4 h enzyme
