摘　　要：棉针织物的传统前处理一般采用高温(约98℃)练漂工艺。处理过程能耗大、排污重,织物失重大、手感粗糙。低温精练剂DM-1377、双氧水活化剂DM-1430、漂特灵DM-1436、双氧水活化剂DM-1435可以在前处理中实现棉针织物60℃低温练漂,与传统前处理相比较,低温前处理后棉针织物的白度略低,但顶破强力、手感、失重、棉蜡保留量均有不同程度的提高。用活性BF-3B红1%(omf)对处理后的棉针织物进行染色,并与传统工艺进行K/S值、色差比较,低温精练剂DM-1377处理后的织物染色性能与传统工艺相近,色差控制在合格范围内,同时具备手感好、强力保留率高、棉蜡保留率高等优点。In the traditional pretreatment of cotton knitted fabrics,exceedingly high temperatures(about98℃)are usually used in the scouring and bleaching process.Such harsh conditions will lead to high energyconsumption,serious pollution,high fabric mass low,tough hand feeling.The low-temperature scouring agentDM-1377,hydrogen peroxide bleaching activator DM-1430,DM-1436,DM-1435could be used in low-tem-perature scouring and bleaching of cotton knitted fabric at60℃.Compared with the traditional process,thewhiteness of fabric treated under low-temperature slightly decreased,while the bursting strength,hand feeling,weight loss,wax reservation all had different degrees of improvement.The treated fabrics were dyed byactive dye BF-3B1%(omf),and the K/S value and color difference of which were compared with those of thetraditional process.It was found that the fabrics treated by DM-1377had the similar dyeing performance withthe traditional process,the color difference was controlled in an acceptable range.And it had good hand feeling,high strength retention rate and high wax retention rate.
