摘　　要：为探究废弃羊毛提取角蛋白改性聚丙烯腈电纺纤维膜的热湿性能,文章以本身保暖性能优异的聚丙烯腈纤维和从废弃羊毛中提取的角蛋白为原料,通过静电纺丝技术,将亲水性的羊毛角蛋白引入聚丙烯腈纤维,结合静电纺丝技术带来的高比表面积和孔隙率,使复合纤维膜具备较佳的吸湿发热性能。结果表明,聚丙烯腈与角蛋白配比为7︰3时,复合电纺纤维膜回潮率达21.3%,吸湿后温度升高了2.3℃,表现出较佳的吸湿发热效果。此研究为废弃羊毛的高效利用及功能性纺织材料的开发提供了技术支持。This study investigates the thermal and hygroscopic properties of polyacrylonitrile(PAN)electrospun fiber membranes modified with keratin extracted from discarded wool.Utilizing PAN fibers,which possess excellent thermal insulation properties,in combination with keratin derived from waste wool,the research explores the potential of these materials to enhance moisture absorption and heat generation.By incorporating hydrophilic wool keratin into PAN fibers via electrospinning,and leveraging the high specific surface area and porosity inherent in fiber structures,the resulting composite fiber membrane demonstrates superior moisture absorption and heat release capabilities.The results indicate that when the ratio of PAN to keratin was 7:3,the moisture regain reached 21.3%,with a maximum temperature increase of 2.3℃after moisture absorption,thereby exhibiting an outstanding hygroscopic heat-generating effect.This study provides technical support for the efficient utilization of waste wool and the development of functional textile materials.
