摘要: 本文探讨了一种亚麻纤维的新型脱胶工艺,通过碱氧一浴、BK-100膨松剂浸泡、机械开松三道工序,运用物理与化学相结合的方式对亚麻纤维进行处理。实验结果表明:碱氧一浴最佳工艺参数:NaOH用量为3.5%,H2O2用量为4%,煮练温度为90℃,煮练时间为80min,BK-100用量4g/L,浸泡时间20min时可取得最佳溶胀效果;脱胶后亚麻纤维断裂强度可达5.02cN/dtex,细度达到2400公支以上。与亚麻湿纺或传统工艺相比,显著改善了其原料品质、纤维可纺性等指标,这为扩大产品应用范围、走亚麻干纺工艺路线奠定了基础。

Abstract: A new method to the degumming process of the flax fiber is discussed in this paper, the degumming in the same water-bath of alkali and oxygen, soaking of Leavening agent (BK-100) and mechanical loosening which use the combination of physical and chemical methods are adopted to process flax fiber. The results indicate that the optimum technological parameter of degumming in the same water-bath of alkali and oxygen are as follows: the dosage of NaOH is 3.5% and H2O2 is 4%, temperature of boiling-off is 90℃,and the time is 80min,the dosage of BK-100 is 4g/L and soaking time is 20min, the maximum impact of swelling under these condition can be obtained . After degumming , the breaking strength of fiber is up to 5.02cN/dtex,and fineness is up to 2400 Nm. Compacted with the wet spinning of flax and traditional techniques, It can improve the quality and spinning property of fibers significantly, which can lay the foundation of expanding its product application and dry spinning process.
