Abstract
Cotton woven fabric was dyed with new developed cationic pigments.The optimum dyeing processes was determined according to single-factor and orthogonal experiments:cationic pigment 10%(omf),liquor ratio 1∶10,pH 8,dyeing at 80 ℃ for 20 min,with the addition of 10 g/L of pigment fastness improver DM-5146,holding at 40 ℃ for 20 min,then the dyed fabric was treated with softening agent silicone oil.The product displayed good color fastness.
