Effect of the Fixation Treatment on the Staining Results of Reactive Dyes for Dyeing Bamboo

Article Preview

Abstract:

In this article, the crushed bamboo bundles were pre-treated with dilute alkali were used as raw materials and then treated with reactive dyes. The influence of the fixing process including Na2CO3 concentration and processing time was studied systematically and an optimized fixing process for dyeing bamboo bundles was obtained. The results showed that:1)These two treatment conditions all can improve the dye uptake and fixation rate; 2)With the increasing of Na2CO3 concentration, the dye uptake and fixation rate are rises gradually and all be increased 20% most, then get the stabilizing when it is 20g / L; The fixation treatment time has little effect on the staining results with the variation range under 7%; 3)The most satisfactory effect could be obtained: The Na2CO3 concentration and processing time is 20g/L and 30min, respectively.
