Application of dyeing process of Sorona blended knitted fabrics
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.
