Application of Cationic Modification Agent to Pigment Dyeing

摘要

Cationic modification experiments were performed to research on the affection of modification agent to pigment dyeing. The influences of modification process condition such as temperature, time, bath ratio, modifier and NaOH dosage etc. were suggested as critical for pigment dyeing. It is observed that, fabric has excellent dyeing depth under the condition of modifier 5 g/L and NaOH 8 g/L, bath ratio 40:1 (water: cloth), modification time 55 min at 70°C.
