摘要
讨论了一种AOX较低的漂白剂——过醋酸在灯芯绒织物上的应用,确定了过醋酸漂白灯芯绒织物的最佳工艺条件:15％的过醋酸 7g/L、pH值 7左右、温度 70℃,时间 80min、焦磷酸钠 3g/L,浴比 1:30。用焦磷酸钠作为过醋酸漂白的稳定剂,对提高白度很重要;同时就漂白效果及染后表观色深与过氧化氢漂白工艺进行了比较。
The optimal process conditions for bleaching of corduroy with peracetic acid are determined and the
importance of using sodium pyrophosphate as stabilizing agent for improving the whiteness in peracetic acid
bleaching is shown. A comparison between its bleaching effect and apparent colour depth with those of hydrogen
peroxide bleaching is made.
