摘　　要：利用氯磺酸进行磺化反应改善聚乙烯(PE)非织物的亲水性,讨论了时间、温度等不同反应条件对PE亲水性的影响,并在KYKY型电子显微镜下观察纤维微观形貌.结果表明,磺化后PE表面纤维发生溶胀的情形,在反应温度为80℃、反应时间为1.5 h、PE非织物的质量(g)与氯磺酸的体积(mL)之比为5∶1的磺化反应条件下,PE非织物的亲水性得到了显著改善,获得了较好的力学性能与较高的磺化率.The hydrophilic property of PE nonwoven web is improved by sulfonation with chlorosulfonic acid. The effect of time, temperature and the ratio of reactants on the hydrophilic property of PE is illustrated. The swelling of sulfonated PE is characterized by observing the micromorphology of PE fibers with SEM. The results show that when temperature is 80℃, time is 1, 5 h and the ratio of the mass of PE nonwoven web and the volume of chlorosulfonic acid is 5 ： 1, the hydrophilic property of PE nonwoven web is excellently improved and the good stretch intensity and higher rate of sulfonation of PE nonwoven web are obtained.
