Title: Comparison between conventional and ultrasonic dyeing of reactive dyes
Abstract: Cotton fabric is dyed with reactive dye,Brilliant Blue KN-R,under ultrasonic condition and conventional condition.The influence of ultrasound on the dye uptake of cotton fiber with reactive dye is analyzed through single factor experiment and orthogonal experiment,and the optimum dyeing processes are received.The results show that ultrasound has promoting action during dyeing process,can increase uptake rate and K/S value.Compared with the conventional dyeing process,ultrasound can not only improve the soaping fastness,but also shorten the dyeing time,increase fixation rate and lower dyeing temperature.The optimum conditions of ultrasonic dyeing are dye 2%(owf),hydrosulfite 50 g/L,trisodium phosphate 8 g/L,dyeing time 105 min,and temperature 50 ℃.
