Study on the Preparation and Properties of Xinjiang Apocynum Venetum Fiber

ABSTRACT

In order to give full play to the economic application value of Xinjiang Apocynum venetum and reduce the environmental pollution caused by the traditional chemical degumming process, a combination of biological and chemical method is used to degum Apocynum venetum. The orthogonal test method is used to explore the optimal parameters for the degumming process. The surface morphology, crystallinity, fineness, strength, moisture regain, and spinnability index of the fibers are tested after degumming. The results showed that after degumming, the fiber fineness was 4.97 dtex, the strength was 22.84 cN/dtex, the crystallinity was 74.5%, the moisture regain reached 7.7380%, and the spinnability was good.

摘要

为了充分发挥新疆罗布麻的经济应用价值, 减少传统化学脱胶工艺对环境的污染, 采用生物与化学相结合的方法对罗布麻进行脱胶. 采用正交试验法探讨了脱胶工艺的最佳参数. 测试了脱胶后纤维的表面形貌、结晶度、细度、强度、回潮率和可纺性指数. 结果表明, 脱胶后纤维细度为4.97dtex, 强度为22.84cn/dtex, 结晶度为74.5%, 回潮率为7.7380%, 可纺性好.
