摘要
超细纤维非织造布在过滤、绝缘、吸收介质等方面有着广泛的应用前景,其纤维直径、孔隙结构对最终产品的性能起着决定性作用。本论文通过水刺法制备出PA6/PE海岛纤维非织造布,采用溶剂二甲苯剥离水刺非织造布中的PE组分制得PA6超细纤维水刺非织造布,并且对比研究了水刺非织造布剥离前后的形态结构、孔径、透气、力学性能以及吸水性能。研究结果表明,经过二甲苯处理后水刺非织造布中的纤维直径从28μm显著下降至792 nm,孔径也下降了85%,吸水能力提高,其断裂强力增加,且纵横向强力均衡,均匀度提高。
Nonwovens made of ultrafine fibers has a big potential in filtration, insulation and absorbing medium market. The pore structure and fiber diameter of nonwovens have a dominant influence on the perfornlance of the final products. In this study, nonwovens made of PA6/PE sea-island fiber was prepared by spunlace process. And after a treatment with xylene, nonwovens composed of ultrafine PA6 fibers was obtained. A comparison of the pore diameters, morphology, permeability and liquid behaviors of the nonwovens before and after the treatment was made. The results showed that after treated by xylene, the fiber＇s diameter was significantly dropped to 792 nm from 28 lain, and the pore diameter decreased by 85%. Moreover, its water-absorbing capacity, breaking strength and nniformity got better.
