摘　　要：聚丙烯PP、聚酯PET、粘胶纤维是3种常见的非织造材料,分别将3种材料在碳弧人工加速老化箱中曝露不同时间,暴晒处理后的样品通过测定其断裂强力及断裂伸长率、电镜扫描分析SEM和红外光谱分析了解其降解性能,并对降解性能进行了评价表征。Three kinds of common non-wovens of polypropylene, polyester and Viscose were respectively exposed in the carbon artificial accelerated aging tank for different duration exposure. After exposure, the breaking strength and elongation of the samples were measured, and the degradation was analyzed by means of scanning electron microscopy and infrared spectroscopy to study and evaluate the degradation performance.
