摘　　要：结合单因素分析和正交试验,以顶破强力和白度为评价指标,优化聚酯基椰炭混纺针织物练漂工艺。优化的练漂工艺为:双氧水20 m L/L,碳酸钠3 g/L,精练剂2 g/L,温度90℃,p H值11,时间70 min,浴比1∶20。结果表明,练漂后织物白度提高至73.5%,织物顶破强力下降了30.6 N,但仍能满足染色工序和织物服用性能的要求。Taking whiteness and bursting strength as indexes, the bleaching process of coconut carbon modified polyester blended knits is optimized using single factor method and orthogonal experimental method. The optimal process is bleaching at 90 ℃ for 70 min with hydrogen peroxide 20 mL/L, sodium carbonate 3 g/L, scouring agent 2 g/L, pH value 11 and bath ratio 1 ：20. The results show that the white- ness of the treated fabric is 73.5%, the bursting strength decreases by 30.6 N, but it still can meet the re- quirements of wearability.
