pH对过氧乙酸预处理亚麻短纤维性能的影响
|
摘要
分析了亚麻短纤维的优缺点,研究了pH对过氧乙酸预处理亚麻短纤维性能的影响。实验表明:最佳pH为5,可以有效去除木质素、果胶和色素等伴生物,失重率、分裂度、白度及强度等综合性能指标满足技术要求,亚麻短纤维的可纺性明显提高,符合成纱及针织圆机纯亚麻汗布的加工和生产。
In this study, the advantages and disadvantages of flax staple fiber were analyzed, and the effect of pH on the performance of peracetic acid pretreated flax staple fiber was studied. The results showed that the optimal pH for the removing of lignin, pectin, pigment etc. accompanied in the short-staple flax was 5. Weight loss, disintegration degree,whiteness and strength of the fibers satisfied the practical requirement. Meanwhile, spinnability of the short-staple flax was improved, which was suitable for the producing of yarn and flax single jersey with circular knitting machine.
