Application of Poly2-Methyl Acrylate-N-Methyl Pyridinium Iodide in Salt-Free Dyeing of Reactive Dyes

Article Preview

Abstract:

Poly2-methyl acrylate-N-methyl pyridinium iodide (PMAMPI) was used as a new cationic agent to pretreat cotton with dip-pad-bake method. The pretreated cationic cotton showed electropositive in the process of dyeing with reactive dye. The thesis has studied the optimized process for salt-free dyeing conditions. In the optimized salt-free dyeing process, the cotton fabrics treated with PMAMPI showed a good performance compared to those in the process of traditional salt dyeing. The results showed that color yield and color fastness of the reactive dyes on the cationic cotton were satisfied. The three dyes with best color matching performance include reactive dark red WGE, reactive navy blue WTE and reactive golden yellow WRE.
