摘　　要：研究了芳砜纶纤维针刺法非织造布经高温处理后,再采用不同浓度次氯酸钙溶液处理,其尺寸稳定性以及物理机械性能的变化情况。结果表明:芳砜纶针刺法非织造布的尺寸和孔径情况无显著变化;厚度、拉伸断裂强力和顶破强力呈整体下降趋势。This article studied the dimensional stability and mechanics properties of the PSA needle-punched nonwovens fabric,which were treated in the different concentrations of sulphuric acid solution after dealing. The result showed that the dimension and aperture of the nonwovens fabric has no significant changes;the thickness,the break strength and bursting strength showed an overall downward trend also.
