However, the rubbing fastness of the dyed fabric with the quaternary copolymer binder containing pigment ink is not enough to be commercially used. Therefore, this study aims to optimize MMA:BA:MAA:NEA composition for improved rubbing fastness. And the binder polymer with various MMA:BA:MAA:NEA compositions were synthesized using miniemulsion polymerization. The particle size, viscosity, molecular weight, and Tg of the synthesized binder were evaluated. And the color strength and rubbing fastness of the black pigment ink dyed cotton fabrics with the prepared binders were also evaluated. Then, the stiffness of undyed and dyed cotton fabrics were evaluated to investigate the changes in touch as the binder structure changes.
