摘　　要：ES纺粘无纺布具有蓬松、柔软、强度好等特点,经亲水改性后是高档卫生用品理想的覆面层材料。为赋予ES无纺布良好的多次亲水性能,研究表面活性剂的结构与其在溶液中的表面张力和在PE薄膜上的动态铺展性能间关系,考察了表面张力、动态接触角、表面活性剂亲水基和疏水基结构等对整理剂性能指标的影响,并优化表面活性剂亲水整理剂配方。结果表明:表面张力值的大小与表面活性剂在PE界面成膜的快慢存在负相关关系,表面张力值越小,成膜速度越快。当整理剂浓度8g/L、烘干温度80℃、烘干时间10min和上油量0.36%~0.42%时,含三硅氧烷聚氧乙烯醚表面活性剂整理剂亲水改性后的ES无纺布具有最佳的多次亲水性能。优化后的亲水整理剂的综合指标(反湿量小于0.11g,第五次穿透时间小于5s,表面比电阻小于2.91×108Ω·cm)已基本达到卫生用品覆面材料对穿透时间(3~5s)、反湿量(小于等于0.13g)和表面比电阻(小于等于7×109Ω·cm)等指标的要求。ES spun-bonded nonwoven fabric has the characteristics of fluffiness,softness and good strength,and it is an ideal material for making high-grade sanitary product coverings after hydrophilic modification.In this paper,in order to give ES nonwoven fabrics good multi-times hydrophilicity,the relationship among the structure of the surfactant,the surface tension in the solution and the dynamic spreading performance on the PE film were studied.And,the effects of surface tension,dynamic contact angle,and the hydrophobic and hydrophilic group structure of the surfactants on the performance of the finishing agents were investigated.The formula of hydrophilic finishing agents of surfactants was optimized.The results indicate that there is a positive correlation between the value of surface tension and the spreading speed of the surfactants on the PE interface.The smaller the value of surface tension,the faster the film forming. ES non-woven fabric finished by the surfactant containing trisiloxanes polyoxyethylene ether owned the optimal multi-times hydrophilic performance under the following conditions：the concentration of finishing agent 8 g/L,the drying temperature 80 ℃,the drying time 10 min and the oiling amount of ES non-woven fabric 0.36% ~0.42%.The comprehensive index of hydrophilic finishing agents after optimization（the amount of back infiltration was less than 0.11 g,the fifth penetration time of ES non-woven fabric was less than 5 s,the surface specific resistance was less than 2.91×10^8Ω·cm）basically met the requirements of the covering material of hygienic products such as the penetration time（3~5 s）,the amount of back infiltration（less than or equal to 0.13 g）and surface specific resistance（less than or equal to 7×10^9Ω·cm）etc.
