促染剂对活性染料染色性能探究

Study on Dyeing Performances of Reactive Dyes with a Dyeing Promoter

通过染色时间和盐用量实验,本文探究了一种复配促染剂对活性染料染色性能的影响。结果表明,复配促染剂对中温型活性染料和高温型活性染料的上染率、固色率以及染色K/S值均有显著提高作用,其染色残液COD值也均有所降低,且染色织物各项色牢度良好。

The effects of a complex dyeing promoter on dyeing performances of reactive dyes were studied by testing dyeing time and salt dosage.The results showed that the dyeing promoter significantly improved the dye-uptake,fixation rate,and K/S value of medi-um temperature reactive dyes and a high temperature reactive dye.The COD value of the dyeing residue was also decreased,and the dyed fabrics had good fastness.
