Hydrophilic multi-porous polyacrylonitrile fiber and comfortability of its product

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 nonwoven fabrics were obtained by weaving M-PAN into nonwoven fabrics and post-treatment of alkaline hydrolysis.The wear-comfort of the HM-PAN nonwoven fabric was studied through comparing with the PAN,nonhydrolyzed M-PAN and cotton nonwoven 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.
