摘　　要：从合成革基布的角度,详细研究了PET/PA6双组分超细纤维/聚氨酯复合片材的微观结构与性能。研究结果表明:该复合片材手感相对丰满紧实,回弹性优异,热稳定性较高,力学性能优异,透气性能与透水汽性能良好,适合作为鞋材。但是复合片材多角形的纤维截面和较低的纤维分离度,导致柔软度较低,延伸性较小,不适合作为服装材料。From the point of view of the synthetic leather fabric, the microstructure and properties of two - component microfi- ber/polyurethane composite sheet material have been studied The research results show that this composite sheet material has the following good performance： relatively fullness and compact, excellent resilience, high thermal stability, excellent mechanical properties, good permeability and water vapor permeability properties, which is suitable for use as shoe materials. But its polygonal shape of the fiber cross section and a lower fiber separation, resulting in a low softness, elongation is small and not suitable for use as clothing materials.
