  Abstract

A pre-treatment method in the digital textile printing (DTP) of pigment ink is a necessary process for improving the color yield and colorfastness of printed fabrics. Depending on the type of binder used in the pre-treatment agent, the fabrics are influenced by the pre-treatment performance and touch. The vinyl acetate-ethylene (VAE) emulsion, which exhibits excellent adhesion properties, is used as a binder in a wide range of applications. Thus, the VAE emulsion is formulated to develop a pre-treatment agent for the DTP of pigment ink. In this study, pre-treatments developed using 12% VAE, 3% calcium chloride, 20% EG, and 1.5% fixative exhibits satisfactory results for pigment ink DTP.
