防缩毛条上染超黑色工艺探讨

Dyeing deep black of shrink resistant wool

主要探讨了活性染料及媒介染料在防缩羊毛上染深黑色的应用。并对染色后的皂洗牢度、摩擦牢度及染色深度等指标进行了测定。实验结果表明,较之媒介染料,毛用活性染料染色工艺时间短,节约能源,不产生重金属铬离子,有利于环保,同时能提高羊毛的皂洗牢度、摩擦牢度及羊毛的强力。

It discussed the dyeing of the shrink resistant wool with reactire dyes and mordant dyes in deep black, tested the fastness to crocking, the soaping fastness and the dyeing depth. The results showed that the dyeing technological process of reactive dyes was short to the process of mordant dyes. The dyeing process with reactive dyes can save energy sources, will not bring heavy metal. The fastness to crocking, the soaping fastness and the strength of wool are all better.
