摘要:

为改进常规聚丙烯腈(PAN)织物的穿着舒适性,将PAN与聚氧化乙烯(PEO)共混后湿法纺丝,经水洗后处理,制成具有微孔结构的改性PAN纤维(M-PAN),然后对用其制成的非织造布进行水解处理,得到HM-PAN非织造布。通过与常规PAN、未经水解的M-PAN及棉非织造布的对比实验研究HM-PAN非织造布的穿着舒适性。结果表明,HM-PAN织物的吸湿、透湿、吸水性能较PAN、M-PAN织物有显著提高,但其吸湿、吸水性能略差于棉织物,透湿性能较棉织物好,透气性能优于PAN及棉织物,略差于M-PAN织物。

Abstract:

In order to improve the wear-comfort of conventional polyacrylonitrile (PAN) fabrics, the modified PAN fibers (M-PAN) with micropore structure were prepared by blending PAN and polyoxyethylene (PEO) via wet-spinning process and water bath post-treatment. Then HM-PAN non-woven fabrics were obtained by weaving M-PAN into non-woven fabrics and post-treatment of alkaline hydrolysis. The wear-comfort of the HM-PAN non-woven fabric was studied through comparing with the PAN, nonhydrolyzed M-PAN and cotton non-woven fabrics under the same experimental conditions. The results show that, in comparison with PAN and M-PAN fabrics, the moisture absorbency, water absorbency, water vapor transmission of HM-PAN fabric improve significantly. The moisture and water absorbency of HM-PAN fabric are poorer than those of cotton fabric, while the water vapor transmission is better than that of cotton fabric. The air permeability of HM-PAN fabric is better than that of PAN and cotton fabrics, but poorer than that of M-PAN fabric.
