Abstract: To overcome the shortage of traditional pigment dyeing, CVC fabric was modified by self-made cationic modifier HL. K/S value, dry/wet rubbing fastness and washing fastness were tested to evaluate dyeing effect, and the optimized modified conditions were defined as follow: modifier HL 10 g/L, NaOH 4 g/L, immersing at room temperature for 5 min, roller pressure 0.25 MPa. The process has the advantages of higher efficiency, lower cost, water and energy saving, and is in line with the concept of environmental protection, so its prospect is promising.

Key words: cationic modification, pigment pad dyeing, CVC fabric, dyeing property
