为了实现废旧纺织品的高价值循环利用，对废旧棉织物进行回收、涂层整理，采用热压成型技术制备棉纤维织物增强聚苯硫醚复合材料。采用十三氟辛基三乙氧基硅烷以及硅改水性聚氨酯对棉织物进行整理，通过抗拉强度对比，后者整理的棉织物增强聚苯硫醚复合材料性能更佳。制备不同热压温度、不同浓度的硅改性水性聚氨酯改性棉织物增强聚苯硫醚复合材料。采用傅里叶变换红外光谱仪（FTIR）、超景深视频显微镜、扫描电镜评价硅改水性聚氨酯处理的棉织物及其复合材料的效果，对制备的复合材料进行力学性能、表面润湿性能、热稳定性和导热性能评估。结果表明：硅改水性聚氨酯的整理提高了复合材料的界面附着力。制备的复合材料的拉伸强度比原聚苯硫醚高167%，弯曲强度高160%，冲击韧性高66.8%。制备的复合材料具有良好的热稳定性和导热性，适用于中等负荷的应用，包括需要足够强度的汽车车身部件和结构部件等。

In order to realize the high-value recycling of waste textiles, waste cotton fabrics were recycled, coated and finished, and cotton fabric-reinforced polyphenylene sulfide composites were prepared by hot press molding technology. Tridecafluorooctyltriethoxysilane and silicone-modified aqueous polyurethane were used to finish the cotton fabrics, and the performance of the latter-finished cotton fabric-reinforced polyphenylene sulfide composites was found to be better by tensile strength comparison. Silicone-modified waterborne polyurethane-modified cotton fabric-reinforced polyphenylene sulfide composites with different hot pressing temperatures and different concentrations were prepared. The effect of silicone modified waterborne polyurethane-treated cotton fabrics and their composites was evaluated using FTIR, super depth-of-field video microscopy and scanning electron microscopy, and the mechanical properties, surface wettability, thermal stability and thermal conductivity of the prepared composites were evaluated. The results showed that the silicone modified waterborne polyurethane finishing improved the interfacial adhesion of the composites. The prepared composite has 167% higher tensile strength, 160% higher flexural strength and 66.8% higher impact toughness than the original polyphenylene sulfide. The prepared composite has good thermal stability and thermal conductivity, which is suitable for medium load applications, including automobile body parts and structural components that require sufficient strength.
