大麻纤维高温煮练时间与脱胶质量的关系

Relationship between high temperature scouring time and degumming quality of hemp fiber

大麻纤维具有无刺痒感、吸湿透气、抗静电、抗菌、屏蔽紫外线等优良性能,但大麻的纺织加工仍存在很多问题,传统的化学脱胶方法仍存在一定的局限性。通过对高温煮练前后大麻组分分析、电镜照片观察及强力指标的测试,探讨在其它因素不变的情况下,高温煮练时间变化对大麻纤维脱胶质量的影响。结果表明,在一定条件下最适合大麻纤维高温煮练的时间为3 h左右。

The hemp fiber has good properties such as antistatic, and shielding ultraviolet radiation. However, non-itching feeling, hygroscopic and air permeable, its processing still encounters a lot of problems, and the traditional chemical degumming of it is not satisfactory. The effect of high temperature scouring time on the degumming quality of the hemp fiber was analyzed by scanning electron microscopy and strength testing. The result shows that the optimal high temperature scouring time for effective degumming of hemp fiber is about 3 hours.
