To solve the problems of large water consumption,long process time and low production efficiency in the traditional dyeing process of Sorona blended knitted fabrics,the dispersed/reactive dyes dyeing process of Sorona blended knitted fabrics was improved.The new improved process is as follows:(1)135℃dispersed dyes dyeing process;(2)reduce the temperature to 98℃for pre-treatment process,reduce the temperature to 95℃for reduction washing process,and then perform 3 times of 55℃washing and one 85℃acid neutralization process,the remaining residual liquid is discharged;(3)room temperature water inlet,60℃reactive dyes dyeing process;(4)discharge the residual liquid from dyeing with reactive dyes into the hair feeding process;(5)two 55℃washing and one 60℃acid neutralization process,one 85℃soap boiling process,55℃color fixing process,and finally 55℃softening process.The new process shortened the process flow of traditional dispersed/reactive dyes dyeing.The results show that the color fastness of fabrics with the new improved dispersed/reactive dyes dyeing process can reach the level of traditional processes,while reducing energy consumption and production cost.
