亚麻纤维乙酰化改性工艺研究

Study on technology of acetylating modified to flax fiber

文章根据纤维素纤维的特点对亚麻纤维进行乙酰化改性,在保持纤维原有特点的基础上使亚麻纤维的微观结构发生变化,从而使纤维更加柔软,物理机械性能发生变化。采用正交试验分析和处理试验数据,研究氢氧化钠的浓度、浸碱时间、乙酸浓度、乙酰化时间等改性条件对纤维物理机械性能的影响,分析改性工艺的主要影响因素与改性后纤维的性能变化,优选出最佳亚麻纤维乙酰化改性的工艺,使改性后的纤维可纺性能得到改善,以适应高支和满足生产高档亚麻轻薄织物的要求。

In this paper, it uses the orthogonal experiment to modify the flax fiber with aeetylating. Through testing the physical mechanical properties of the flax fiber, the influences of the modified condition, such as the caustic soda density, infusion time, acetate density and acetylating time, are optimized. So the best-modified technology of the flax fiber can be concluded and the properties of modify the flax is improved in the spianability.
