Wet comfort is a critical performance for fabrics, especially when human bodies release sweat in daily life. Despite excellent moisture absorption performance, cotton yarns are still limited in the moisture release/transfer ability. Here, based on a novel electrospinning technology, polyacrylonitrile and polystyrene (PS) electrospun nanofiber/cotton composite yarns were produced, respectively. Under fluorescence microscopic observation, electrospun fibers within the composite yarns showed a uniform distribution. As a result, these composite yarn-based knitted fabrics obtained a good water transport ability and a fast water evaporation rate. According to the moisture management test, PS electrospun nanofiber composite yarn-based fabrics exhibited a relatively high one-way transport index R (400%), claiming an enhanced moisture management performance. Finally, specific surface area tests and finite element analyses were used to analyze the water transport mechanism inside the yarns. The results proved that a small number of electrospun fibers played a predominant role in enhancing the moisture management ability of the composite yarns.

湿舒适性是织物的一项关键性能，尤其是当人体在日常生活中释放汗水时。尽管具有优异的吸湿性能，棉纱的释放/转移能力仍然受到限制。在此，基于一种新型的静电纺丝技术，分别生产了聚丙烯腈和聚苯乙烯（PS）电纺纳米纤维/棉复合纱。在荧光显微镜观察下，复合纱线内的电纺纤维表现出均匀的分布。结果，这些复合纱线基针织物获得了良好的水传输能力和快速的水蒸发速率。根据水分管理测试，PS电纺纳米纤维复合纱基织物表现出较高的单向传输指数R（400％），声称增强了水分管理性能。最后，通过比表面积测试和有限元分析来分析纱线内部的水传输机理。结果证明，少量的电纺纤维在增强复合纱线的水分控制能力方面起着主要作用。
