| 摘 要： | 为探究不同企业Lyocell纤维性能及产品质量差异，随机选取国内外9家不同企业的Lyocell纤维，对其表观形貌、力学性能、磨损性能、结晶度、取向度、并丝率等进行深入表征与对比分析。结果表明：国外企业生产的Lyocell纤维表观形貌规整且光滑，横切面呈圆形，其湿磨损值为8.76 s,结晶度为78.8%,原纤化程度较低，并丝率较低(2.591%),纤维断裂强度为3.91 cN/dtex,断裂伸长率为9.79%,纤维及成纱强力高、品质优异，在下游应用市场中具有较高的认可度；因工艺路线及后处理工艺的差异，国内企业生产的Lyocell纤维品质较国外的有一定差距，未来应在微观形貌、并丝率、光泽性、可纺性及品牌推广等方面继续优化，进一步提高其市场占有率。

| Abstract: | Objective A varity of Lyocell fibers in the market are different in the product quality and spinnability. In order to understand the performance and quality differences of different Lyocell fibers and the analysis of the causes, this research systematically studied the differences of Lyocell fibers in terms of morphological structure, mechanical properties, wear properties, crystallinity, orientation and filament ratio, and analyzed the reasons for the differences. This paper provided suggestions for the subsequent improvement and development direction of domestic Lyocell fibers. |
