静电纺丝网具有良好的防护性和舒适性，可广泛应用于防护服装或特种纺织品。在这项研究中，特别感兴趣的是通过将聚氨酯静电纺丝网直接施加到基底织物上来开发防水透气织物。考察了最佳静电纺丝条件，包括纺丝液浓度、施加电压和针尖-收集器距离。以N，N-二甲基乙酰胺为溶剂，在最佳条件下对聚氨酯进行溶剂静电纺丝。将0.02mm厚的静电纺丝网施加到聚酯/尼龙共混织物上。为了比较，采用四种不同的条件用0.02mm厚的聚氨酯树脂膜涂覆聚酯/尼龙织物。将静电纺PU网/织物与树脂涂覆织物在防水和透气性能方面进行比较。静电纺丝织物的透气性、透汽性和隔热性均高于树脂涂层织物，说明静电纺丝织物具有更好的舒适感。然而，静电纺丝网应用织物的耐水性值没有达到树脂涂覆织物的耐水性值。
Electrospun web may possibly be widely applied to protective garments or specialty textiles due to its high level of protection as well as comfort. Of particular interest in this study is to develop waterproof-breathable fabric by applying electrospun web of polyurethane directly onto the substrate fabric. The optimal electrospinning condition was examined with regards to the concentration, applied voltage and tip-to-collector distance. Solvent-electospinning of polyurethane was performed at the optimum condition, using N,N-dimethylacetamide as solvent. The thickness of 0.02 mm of electrospun web was applied onto the polyester/nylon blended fabric. For comparison, the polyester/nylon fabrics were coated with 0.02 mm thickness of polyurethane resin membranes adopting four different conditions. The electrospun PU web/fabric was compared to resin coated fabrics in terms of water-proof and breathable properties. The electrospun web applied fabric showed higher air permeability, vapor transmission, and thermal insulation properties than resin coated fabrics, which can be translated as greater comfort sensation of electrospun applied fabrics. However, water resistance value of electrospun web applied fabric did not reach that of resin coated fabrics.
