摘要
云南亚麻因胶质含量偏多、纤维内在质量差异大而一直得不到广泛应用。采用碱氧一浴的化学脱胶方法对云南亚麻进行处理,探讨了NaOH、H2O2用量,煮练温度和煮练时间4个因素对脱胶效果的影响。通过正交试验确定云南亚麻的最佳脱胶工艺为:NaOH用量4%,H2O2用量6%,煮练温度90℃,煮练时间135 min,测得纤维断裂强度达到4.80 cN/dtex,细度达到2 000 Nm。试验结果表明,经最佳脱胶工艺得出云南亚麻纤维的断裂强度和细度与常规亚麻非常接近,可以部分替代常规亚麻。
Yunnan flax cannot be widely used because of its too much gum content and difference among the fibers intrinsic quality. The chemical degumming in the same water-bath of alkali and oxygen is adopted to process Yunnan flax. The influence of degumming effect was researched by dosage of NaOH and H2O2, temperature and time of boiling-off etc.. The optimum degumming was determined by orthogonal test. The dosage of NaOH was 4% and H2O2 was 6%, temperature of boiling-off was 90℃, and time was 135 min. The rupture strength of fiber was up to 4.80 cN/dtex, and fineness was up to 2000 Nm. The results indicated that the rupture strength and fineness of Yunnan flax was close to regular flax so that it could be substituted for regular flax partly.
