苎麻织物活性染料深浓染色工艺方法研究

Dyeing process research on deep dyeing of ramie fabric with reactive dyes

采用浓碱与自制的阳离子明胶蛋白助剂联合处理苎麻织物,探讨浓碱预处理条件(碱用量、处理时间)对改性效果和活性染料染色效果的影响,并研究阳离子蛋白助剂改性条件(助剂用量、氢氧化钠用量、改性时间、改性温度)对苎麻织物活性染料染色的上染百分率、固色效率、染色深度的影响,确定了最佳苎麻预处理条件及浸渍改性条件。结果表明,经浓碱预处理后,再经阳离子明胶蛋白助剂改性的苎麻织物染色性能显著改善,活性染料利用率明显提高。

Ramie fabric was treated with the combination of strong alkali and self-made cationic gelatin protein.The influence parameters of the strong alkali pretreatment conditions（alkali dosage,treatment time） on the modified and dyeing effects were all discussed.And then the effects of cationic protein modified conditions（cationic gelatin dosage,sodium hydroxide dosage,modification time and temperature） on the fabric dyeing uptake,fixation rate and dyeing depth were investigated.The optimization parameters of ramie fabric pretreated and modified conditions were confirmed.The results showed the dyeing properties and reactive dyes utilization ratio of modified ramie fabric were able to be significantly improved,which was pretreated with the strong alkali and then treated with self-made cationic gelatin protein.
