摘要
为优化Lyocell纤维上油工艺,提高其后续加工性能,采用恒温淋洗、恒压压榨的方法对Lyocell纤维进行上油处理,利用扫描电子显微镜、纤维强伸度仪、纤维摩擦系数仪、纤维比电阻仪等手段进行表征分析,详细研究了油剂浓度、油剂混合比、上油温度等不同上油工艺对Lyocell纤维的成膜性、摩擦性能、抗静电性能及力学性能的影响。结果表明:当上油质量浓度为6 g/L、油剂组分中弱阴离子表面活性剂质量分数为31%,上油温度为65℃时,油剂在纤维表面形成的油剂层厚薄均匀,纤维平滑性较好;力学性能较优,纤维断裂强度为3.92 cN/dtex,断裂伸长率为11.38%;抗静电性能及纤维间抱合性最强,纤维体积比电阻最低为5.66×10^(9)Ω·cm,纤维间抱合力达223.0 cN。
In order to optimize the oiling processing of Lyocell fibers and improve its subsequent processing performance,Lyocell fibers were oiled under the condition of constant temperature leaching and constant pressure pressing.The effects of oil concentration,oil mixing ratio and oil temperature on the film forming,friction performance,antistatic performance and mechanical properties of Lyocell fibers were studied in detail by means of scanning electron microscopy,strength and elongation analysis,friction factor analysis and volume resistance analysis.The results showed that when the oil concentration was 6 g/L,non-ionic surfactant content was 31%,the oil temperature was 65℃,the thickness of oil agent layer form on the fiber surface was even and the fiber smoothness was good.The mechanical properties of fiber were excellent.Fiber breaking strength was 3.92 cN/dtex,elongation at break was 11.38%.Antistatic properties and cohesiveness of fibers were best.Volume resistance of fiber was 5.66×10^(9)Ω·cm and cohesiveness between fibers was 223.0 cN.
