Abstract


The salt-free dyeing of cotton fabric were studied, at the same time, the influence of dye dosage, pH value, temperature, liquor ratio and dyeing time on dyeing behavior were discussed in this paper. The results showed that the suitable dyeing conditions of carboxymethylly modified cotton fiber with Astrazon red FBL were as follows: the dosage of Astrazon red FBL was 2% o.w.f, the dyeing pH value was 6-7, the temperature was 70℃, the ratio was 1:20, and the dyeing time was 70 min. Under the conditions of the dyeing process, the dyeing K/S value of the modified cotton fiber can up to 26 or so.
