摘　　要：采用硫酸对超细纤维合成革基材进行水解处理,通过单因素试验和正交试验优化出最佳作用条件:硫酸用量为15%(以基布的质量计),作用温度为50℃,作用时间为4 h。在最佳作用条件下水解后,超细纤维合成革基布的氨基含量增加了105.1%,撕裂强度较未处理前提高了14.7%,抗张强度提高了14.69%,透水汽性提高了13.54%,断裂伸长率提高了69.87%。The microfiber synthetic leather substrate was hydrolyzed by sulfuric acid. By the method of one - factor experimental design, some correlative factors which influenced the hydrolysis of microfiber synthetic leather substrate were investigated. And the appropriate action conditions were optimized as follows： the dosage of sulfuric acid was 15% （according to substrate weight） , reaction temperature 50 ~C, reaction time 4 h. Compared to untreated substrate, under the appropriate action conditions, the content of amino -group increased by 105.1%, the tear was improved by 14. 7%, the tensile strength improved by 14. 69%, the water vapor was improved by 13.54%, breaking elongation improved by 69. 87%.
