The Study of Degradable Chitosan in Low Salt Dyeing of Cotton Fabric with Reactive Dyes
Cotton fabrics were treated with degradable chitosan as dyeing auxiliary of reactive dyes. The dyeing rate and fixation rate and rubbing fastness dyeing of before and after worked cotton fabric were compared. On the basis of the research of low salt reactive dyes dyeing process of cotton fabric the dye uptake rate, and fixation were re-searched. The result showed that the dyeing property and the dye uptake rate were improved significantly on degrad-able chitosan pre-treatment of cotton fabric. The pollution to the environment in the process of dyeing was reduced. The optimum process conditions of degradation of chitosan pre-treatment: was the dipping temperature 80 ℃, the degradable chitosan dosage of 0. 8%(on weight of fabric) , and dipping time 30 min.
