The reactive dyeing of polyamide 56 fabric has been studied,but the dyeing process has the problems of long process and low dye uptake.The reactive dyeing technology of PA56 fabric and its blended fabric is mainly stud-ied,and a new dyeing process of"rolling,drying and steaming"is developed.Compared with the conventional reactive dyes dyeing technology,this new process shortens the process and realizes less salt dyeing.At the same time,PA56 has high dye uptake and excellent color fastness,which improves the first-class product rate.
