The Role of Binders and Its Chemistry in Textile Pigment Printing

Abstract

Asaye Dessie,Bezaneh Eshetu

This review paper presents the chemistry of binders and their action in pigment printing of cellulosic textile substrate.  Printing of textile materials is probably best described as an industrial art, having a long history and an assured future. Textile printing is the most versatile and important of the methods used for introducing color and design to textile fabrics. In pigment printing, insoluble pigments, which have no affinity for fibers, are fixed on to the fibers with binding agents or binders.  In textile printing, dyes or pigment are transferred to textile fabric by printing pastes. Binders are the mechanism used to keep the color on the fabric when using pigments for printing textiles. The choice of binders will always depend upon the final fastness requirements as well as the cost requirements of the process. Almost all the binders used in textile pigment printing are the addition polymerization products. The binder is a film forming substance made up of long chain macromolecules, which when applied to the textile together with the pigment , produce a three dimensionally network. Different binders were also developed for the purpose, resulting finally in the use of water- in-oil, and oil-in-water emulsions. This greatly accelerated the use of pigments in textile printing and then pigments have become major coloring matters used in printings. This paper review gives more emphasis on the need and functions of binder in pigment printing and also the chemistry of binders and its action in fixation of the pigment onto the textile substrate.
