大豆蛋白涤纶混纺纱纤维分布探讨

Discussion of Fiber Distribution of Soybean Protein Fiber Polyester Blended Yarn

通过切片等方法对不同混纺比大豆蛋白纤维与涤纶混纺纱纤维分布规律进行了分析和比较,得出Ham ilton和On ion指数。结果表明:大豆蛋白纤维含量为40%时,大豆蛋白纤维与涤纶混纺纱的实际分布与均匀分布On ion指数差异率最大,大豆蛋白纤维有效利用率最高。大豆蛋白纤维和涤纶纤维在混纺纱中的转移规律并不完全符合传统的转移规律。

Regularity of fiber distribution in soybean protein fiber polyester blended yarn which has different blending ratio were analyzed and compared through chip and other methods, Hamilton index and Onion index were calculated. The result shows——when the blending ratio of soybean protein fiber is 40% , the difference rate of Onion index between practical distribution and evenness distribution is biggest, effective utilization of soybean protein fiber is highest. The transfer regularity of soybean protein fibers and polyester fibers in blended yarn is not completely in accordance with the traditional transfer regularity.
