摘要 利用自主改进的静电纺丝装置制备亲水性聚丙烯腈(polyacrylonitrile,PAN)与疏水性聚氯乙烯(polyvinylchloride,PVC)微纳米纤维/棉纤维包芯纱,并将其作为纬纱织造织物小样。结合扫描电子显微镜(scanning electron microscope,SEM)进行包芯纱表面形貌表征与纤维直径测量,测试纱线强力,并对织物进行形貌观察以及水接触角测试与液态水分管理性能测试,以研究不同亲疏水性的微纳米纤维/棉纤维包芯纱对其织物导湿性能的影响。试验结果表明:亲水的PAN微纳米纤维/棉纤维包芯纱能够增强织物的导湿性,疏水的PVC微纳米纤维/棉纤维包芯纱对织物导湿性能的提升无积极作用;相比纯棉纱织物,PAN包芯纱/棉纱织物液态水单向传递指数提高了4级,并赋予其单向导湿性能。 The hydrophilic polyacrylonitrile(PAN)and hydrophobic polyvinylchloride(PVC)micro-nano fiber/cotton fiber composite yarns were prepared using a modified electrospinning device,and they were weaved into fabric samples as weft yarns.The scanning electron microscope(SEM)was used to test the surface morphology and fiber diameter of composite yarns.And yarn strength,fabric morphology,water contact angle and liquid moisture management performance were tested to investigate the effect of different hydrophilic micro-nano fiber/cotton fiber composite yarns on the moisture permeability of fabrics.The results show that the hydrophilic PAN micro-nano fiber/cotton fiber composite yarn can enhance the moisture permeability of the fabric,and the hydrophobic PVC micronano fiber/cotton fiber composite yarn has no positive effect on the fabric's moisture permeability.Compared with pure cotton yarn fabric,the liquid water one-way transmission index of PAN composite yarn/cotton yarn fabric increases by four levels,and the fabric is imparted unidirectional wettability.
