涤/棉混纺针织物高效漂染一浴两步工艺

One-bath two-step process for efficient bleaching and dyeing of polyester/cotton blended knitted fabrics

高效漂染一浴两步工艺代替常规漂染工艺处理涤/棉混纺针织物,具有良好的棉精练及涤染色效果。工艺条件为:TF-213HL 0.5%(omf),分散染料0.5%(omf),浴比1∶10,130℃处理30 min,不排液降温至85℃处理30 min,并加入TF-1291K 1.0%(omf),NaOH 0.6%(omf),H_(2)O_(2)8.0%(omf)。

The efficient bleaching and dyeing one-bath two-step process replaces the conventional bleaching and dyeing process for polyester/cotton blended knitted fabrics,which has good cotton refining and polyester dyeing effects.The process conditions were:TF-213HL 0.5%(omf),disperse dye 0.5%(omf),bath ratio 1∶10,130℃treated for 30 min,no drainage cooling to 85℃,added TF-1291K 1.0%(omf),NaOH 0.6%(omf),H_(2)O_(2)8%(omf),treated for 30 min.
