摘　　要：采用低温弱碱氧漂前处理工艺,以TF-1791作为低温练漂剂,通过优化工艺可显著提升腈/棉/氨针织物的白度。优化的工艺条件为:w(TF-1791)2%(omf),w(TF-1291A)2%(omf),w(30%H_(2)O_(2))12%(omf),pH=8,浴比1∶8,工艺温度80℃,工艺时间60 min。The whiteness of acrylic/cotton/spandex knitted fabric can be significantly improved by using low tem⁃perature weak alkali oxygen bleaching pretreatment process and TF-1791 as low temperature scouring and bleaching agent.The optimized process conditions are w(TF-1791)2%(omf),w(TF-1291A)2%(omf),w(30%H_(2)O_(2))12%(omf),pH=8,bath ratio 1∶8,pretreatment at 80℃for 60 min.
