摘要
采用捻度仪对大豆蛋白纤维、珍珠纤维、天丝纤维、牛奶蛋白纤维的单次扭转极限、重复扭转疲劳性能进行了测试,同时测试了4种纤维在扭转前后的拉伸性能。测试结果显示:大豆蛋白纤维的单次扭转极限较大,但重复扭转疲劳性能下降比较明显;扭转一定圈数后,纤维的拉伸性能下降得也比较明显,生产中要注意减少大豆蛋白纤维的扭转以延长其使用寿命。
The single torsional limit and repeated torsional fatigue of four kinds of fibers such as soybean protein fiber, Pearl fiber, tencel fiber and milk protein fiber are tested by twist tester, and the tensile performance before and after torsion are also tested. The results show that the single torsional limit of soybean protein fiber is larger, but the performance of soybean protein fibers decreases obviously under repeated torsion, and the decrease of tensile performance after torsion for a certain number of turns is also obvious. In production, attention should be paid to reducing the twist of fiber to prolong the service life of products.
