Abstract:

With a view to investigate the hygroscopic property of soybean protein/cellulose blend fibers, the moisture regain, hygroscopic and moisture liberation properties of the fibers are tested under standard condition. The hygroscopic and moisture liberation regression equations are achieved, and the regression equations of velocity of hygroscopic and moisture liberation are derived. The hygroscopic properties of blend fibers with different soybean protein ratios are compared, including comparaing with bamboo, flax and jute fibers. The results reveal that the hygroscopic property of soybean protein / cellulose blends fibers increases with increasing the blend ratio of soybean protein. The hygroscopic velocity of blend fiber with 16.2% soybean protein lies between that of bamboo and flax, and the moisture liberation velocity is better than those of bamboo, flax and jute fibers.
