锦纶织物的MC型酸性染料染色

Polyamide dyeing with MC acid dyes

采用MC型酸性染料对锦纶进行染色,探讨了酸性染料质量分数、染色时间、染色温度、染液p H值和LSP匀染剂对锦纶染色K/S值、上染百分率和固色率的影响。结果表明,MC型酸性染料处理锦纶的最佳工艺条件为:染料质量分数2.5%(omf),渗透剂0.5 g/L,染液p H值5,染色温度98℃,染色时间40 min,LSP匀染剂0.5 g/L。LSP匀染剂在锦纶染色中能提高织物的K/S值和匀染性,MC型酸性染料染锦纶具有较好的耐洗和耐摩擦色牢度。

The polyamide dyeing with MC acid dyes is carried out. The effects of dye concentrations, dye- ing time, dyeing temperature, pH value and LSP leveling agent on K/S value, dye uptake and fixation are discussed. The result shows that the optimal dyeing process of polyamide fabric with MC acid dyes is： acid dye 2.5%（omf）, penetrating agent 0.5 g/L, pH value 5, dyeing at 98 ℃ for 40 min, LSP leveling agent 0.5 g/L. The use of LSP leveling agent can improve the K/S value and levelness of dyed polyamide fabric, and the color fastnesses to washing and rubbing of the dyeings are good.
