Abstract
The use of the four new synthesized polyurethane acrylate binders in the pigment print paste for screen printing cotton and polyester fabrics and pigment fixation through the polymerization process of the binder by using the thermofixation technique as well as the UV curing technique was studied. The effect of changing time and temperature of thermofixation, and the time of UV curing on the color strength, and prints fastness properties were also studied. The results showed that, the newly synthesized polyurethane acrylate binders could be successfully used for pigment fixation on cotton and polyester using the two fixation techniques and in general their prints possessed better color strength values as compared to those obtained upon using the selected commercial binders.
Highlights
Pigment printing is the oldest and the easiest printing method as far as simplicity of application is concerned [1,2,3,4,5]
The aim of this work was to investigate the use of the synthesized aqueous polyurethane acrylate binders, having zero volatile organic emissions based on glycerol Ethoxylate-Co-Propoxylate triol in pigment printing of cotton and polyester fabrics by the silk screen technique, and pigment fixation through the polymerization process of the binder by using the thermofixation technique, as well as the newly adopted UV technique
It could be safely concluded that, the four synthesized aqueous polyurethane acrylate binders could be successfully employed for pigment fixation on screen printed cotton, and polyester via polymerization of the binders during the thermal and UV curing processes and in general, their prints possessed better color strength values as compared to those obtained upon using the commercial
Summary
Pigment printing is the oldest and the easiest printing method as far as simplicity of application is concerned [1,2,3,4,5]. Pigment printing makes use of kerosene or mineral turpentine which is involved in making emulsion thickeners. In this system, the kerosene in the emulsion gets evaporated to the atmosphere at the time of curing of the pigment printed fabric [6]. In spite of the superior thickening properties of kerosene water emulsion which contribute towards a soft hand of the print, good fastness properties, ease of application methods, and economy. Several other factors have compelled the search for a replacement for kerosene; some of these are [7]: 1) The ongoing oil crisis, both in terms of cost and availability makes it imperative to minimize kerosene use
