摘　　要：将氧漂活化剂NOBS应用于棉针织物一浴练漂工艺。通过单因素试验和正交试验,分析各工艺因素对织物漂白效果的影响,得优化的棉织物练漂工艺:煮练剂DM-1361 0.4 g/L,低温练漂促进剂DM-13701.5 g/L,H2O2(35%)6 g/L,NaOH2 g/L,NOBS 1 g/L,80℃处理60 min,浴比1∶10。该活化漂白工艺高效节能,能在低温下使织物达到较高的白度和毛效。Application of activator nonanoylbenzene sulfonate （NOBS） to low temperature peroxide bleaching of cotton knits was proposed. Influences of process conditions on bleaching effect were investigated through single factor analysis and orthogonal experiments. Optimum conditions were DM-1361 0.4 g/L, DM-1370 1.5 g/L, H2O2（35%）6 g/L, NaOH 2 g/L, NOBS 1 g/L,tiquor ratio 1 ： 10, pretreating at 80 ℃ for 60 minutes. Results showed that bleaching with the activator featured better whiteness and capillary effect compared with conventional scouring and bleaching process.
