Cationic modification and pigment exhaust dyeing of silk fabric

Cationic modification are carried out on silk fabric with cationic modifier S-PD01,and followed by pigment dyeing with pigment pink 118.The parameters of cationic modification and pigment dyeing are discussed.The optimum processes are modification at 70 ℃ for 40 min with S-PD01 7%(omf) and pH value 9~10,and exhaust dyeing at 60 ℃ for 30 min with pigment 6%(omf).The pigment dyeings of silk with cationic modification have obvious improved K/S value compared with those without modification.The color fastness of the dyeings are poor,but can be improved with fixation.
