Optimization on the Low-Temperature Dyeing Process of Wool

By previous experimental study of low temperature dyeing for wool have demonstrated that low temperature additives 640 can open the disulfide bonds in the wool fiber,make the wool structure become loose,improve the diffusion coefficient of dye uptake significantly,so it is easy to dye uptake of wool fiber and improve the dyeing depth,which can be realized low temperature dyeing.However surfactant has effect of solubilization,dispersion,emulsification,penetration,can better depolymerization dye and enhance the staining effect..In this paper,through multiple sets of experiments to select the best wool low temperature dyeing recipe and dyeing curve.Dyeing under the conditions of 80℃ and 85℃,and then compared with the conventional dyeing process,the results show that dyeing with the optimal wool low temperature dyeing we have elected,all kinds of fastness,color difference can reach the level of the conventional dyeing process.
