ABSTRACT

The previous study reported that the quaternary copolymer of MMA, BA, MAA, and NEA was expected to be a good monomer composition for a binder polymer with good rubbing fastness for digital textile printing (DTP) pigment ink. 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 compoistion for improved rubbing fastness. And the binder polymer with various MMA:BA:MAA:NEA compoistions 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.
