摘要
聚乳酸纤维是一种新型的“环保纤维”,将其以不同捻系数纯纺及与天丝纤维以不同混纺比混纺成纱,对其成纱分别进行了拉伸性能试验分析,并探讨了纯纺纱捻系数、混纺纱的混纺比与纱线强度和伸长率之间的关系,结果表明,混纺纱的混纺比与纱线强度之间的关系是符合汉姆伯格简化力学模型。确定了聚乳酸纤维与天丝纤维混纺时的最佳混纺比及聚乳酸纤维纯纺和混纺纱的临界捻系数在405.9区域附近。
The PLA fiber is one of the green fibers. It is blended with Tencel fibers. The strength of the blended yarn is tested. The relationship between the strength, the twist factor, and the blended ratio is analyzed. The relationship between the strength and the blended ratio of the blended yarn is in accordance with the Hanmburge model. The optimum blended ratio and the critical twist factor of the blended yarn are determined.
