Low salt dyeing of cotton fabric with reactive dyes

Cationic modified cotton fabric is dyed with reactive dyes.The results show that low salt dyeing of cotton fabric can be realized with high fixation yield,cationic modification is carried out at 80 ℃ for 55 minutes with cationic modifier 9.5 g/L,NaOH 5.0 g/L and bath ratio 50 ∶ 1,and low salt dyeing is undergone at 55 ℃ with reactive dyes 2%(omf),anhydrous sodium sulphate 10 g/L and bath ratio 50 ∶ 1,dyeing time for Argazol red is 60 minutes,for Argazol yellow and Argazol turquoise blue is 50 minutes respectively.
