摘　　要：为提高Lyocell纤维的吸湿性,以三聚氯氰为载体,通过化学改性在Lyocell纤维表面接枝引入氨基酸等极性基团。分析了不同碱处理浓度、浸碱时间、反应温度、反应时间下各组试样的吸湿性,并对改性前后的形貌、结构、力学性能进行对比。结果表明:质量分数5%的NaOH溶液处理30 min,添加制备的多羧基氨基三聚氯氰衍生物中间体,在90℃条件下反应6 h,Lyocell纤维水刺材料的吸湿效果最好,且仍具备良好的力学性能,可满足高吸湿性水刺非织造材料的使用要求。In order to improve the hygroscopicity of Lyocell fibers,the surface of Lyocell fiber was chemically modified by grafting with amino acid and other polar groups using cyanuric chloride as carrier.Moisture absorptions of samples in each group with different experimental conditions such as alkali treatment concentration,soaking time,reaction temperature,reaction time,etc.were analyzed.The morphology,structure and mechanical properties before and after modification were compared.The results showed that treatment with 5%NaOH solution for 30 min,adding the prepared polycarboxylic amino melamine derivative intermediates and reaction at 90℃for 6 h were the optimum conditions,and Lyocell fiber spunlaced material has the best hygroscopic effect and better mechanical properties,which can meet the use requirements of high hygroscopic spunlaced nonwoven materials.
