Printing is known as localized dyeing of fabric or garments by applying different styles and methods. In this study, the colorfastness and color durability of synthetic (acrylic) printed fabric was improved by the application of synthetic printing fixer (Anionic acrylic polymer). Moreover, different percentage of fixer with different viscosity or wicking effects of chemical viscosity on colorfastness was investigated. In this study, the fixing agent (2-5%) has a good wash fastness effect and rubbing fastness effect on rubber and Emboss-rubber printed fabric. Furthermore, there is no effect of the fixing agent in light fastness on printed fabric.
