摘要
探讨了固色代用碱简易替DS在纯棉筒子纱活性染料染色中的应用,分析了元明粉用量、代用碱用量、固色温度、固色时间等工艺因素对染色效果的影响,通过工艺因素水平及正交试验,优化了代用碱在纯棉筒子纱活性染料染色中的工艺条件。试验结果表明,简易替DS用量少、化料简便、在染液中分散均匀,固色效果与传统碱剂相当,可取代传统的纯碱固色工艺。
Liquid alkali was applied to fixation of reactive dyes in cheese dyeing of cotton yarns instead of conventional soda ash, factors exerting influence on dyeing results were analyzed, including concentrations of sodium sulfate and liquid alkali, fixing time and temperature, and so on. The optimum conditions of cheese dyeing were defined via orthogonal experiments. Resuits showed that the dyeings fixed with liquid alkali featured similar color fastness compared with those with conventional soda ash as fixing agent.
