大豆蛋白/纤维素共混纤维的吸湿性能

Moisture adsorption property of soybean protein/cellulose blend fibers

为了解大豆蛋白/纤维素共混纤维的吸湿性,测试该纤维在标准温湿度条件下的回潮率、吸放湿曲线,并建立该纤维的吸、放湿回归方程,推导吸、放湿速率回归方程。分析不同大豆蛋白共混量的大豆蛋白/纤维素共混纤维的吸湿性,对比分析该纤维与竹纤维、亚麻及黄麻纤维吸湿性的差别。结果发现:共混纤维的吸湿性随着大豆蛋白质含量的增加而提高;含16.2%大豆蛋白质的共混纤维的吸湿速率介于黄麻纤维和竹纤维、亚麻纤维之间,放湿速率优于这3种纤维素纤维。

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 comparing with bamboo,flax and jute fibers.The results reveal that the hygroscopic property of soybean protein /cellulose blend 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.
