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.
