改性苎麻织物活性染料染色性能研究

Research on Dyeing Behaviors of Modified Ramie Fabric with Reactive Dyes

采用浓碱预处理与自制的阳离子明胶蛋白助剂联合处理苎麻织物,研究了改性苎麻织物活性染料染色的上染百分率、固色率、染色深度、染色牢度等性能。结果表明,经浓碱预处理及阳离子明胶蛋白助剂改性联合处理的苎麻织物染色性能显著提高,可实现活性染料无盐低碱深浓染色。

Ramie fabric was pretreated by strong alkali, and then with self-made cationic gelatin protein. The dyeing effect of modified ramie fabric was discussed, including dye uptake, fixation yield, dyeing depth and color fastness. The results showed the pretreatment process could effectively improve the dyeing effect, and achieve dyeing with salt-free and lower alkali dosage.
