摘　　要：采用次氯酸钠氧化法对废旧毛/涤混纺织物进行分离和降解研究。通过分析次氯酸钠浓度及其与毛/涤混纺织物的质量比、反应时间和温度等影响因素,确定优化的降解工艺条件为:次氯酸钠浓度5 mol/L,次氯酸钠与混纺织物的质量比为40∶1,65℃反应2.5 h,可将毛/涤混纺织物中的羊毛完全降解,分离得到可回收利用的涤纶纤维。The waste wool/polyester fabric is separated and degraded with sodium hypochlorite oxidation method. By analyzing the influencing factors such as sodium hypochlorite concentration, reaction time and temperature, the process conditions of degradation are obtained： sodium hypochlorite concentra- tion 5 mol/L, the ratio of sodium hypochlorite to blended fabric 40： 1, reaction at 65℃ for 2.5 h. With the above process, the wool fiber in blended fabric can be completely degraded and the reusable polyester fiber can be obtained by separation.
