Abstract—A comparative analysis of the aqueous dispersions of acrylic polymers when used in the technologies of pigment coloration of textiles was carried out. The aim was to explore the suitability and efficiency of domestically produced acrylic polymer modifiers as primers for thermal transfer printing applications. For comparison served urethane polymers available from foreign manufacturers, widely used for textiles finishing in the Russian textile industry. Selection of film-forming agents from among domestic polymers was carried out with a view to identifying the modifier most effectively increasing the degree of transfer of disperse dyes from the transfer paper to cellulose-containing textile materials.

DOI: 10.1134/S1070363220090303 The textile industry is part of the industries that pose serious threats to the environment, which is particularly relevant to textile finishing processes. An essential precondition to successful addressing these threats it switching to more economically and environmentally beneficial operating practices based on technologies using low-toxicity, fireproof substances, as well as energy-, heat-, and water-efficient processes. In textiles finishing, this concerns various no-rinse fabric coloration techniques (dyeing, printing). One popular indirect process that is currently used for textiles coloration is sublimation printing. Its main disadvantage is that the dyes can be fixed on synthetic materials solely; accordingly, fabrics should contain no less than 65% synthetic (mainly polyester) fiber. The reason lies in the fact that sublimation printing technologies employ dispersed dyes characterized by the highest affinity for synthetic fibers. A method of chemical modification of textiles that might be useful in making cotton fabrics more sensitive to disperse dyes is based on the fabric treatment with polymer modifiers, accomplishable with the use of waterdispersed acrylic (co)polymers. Digital and/or transfer printing of cellulose-containing fabrics consists in applying sublimation inks (dyes) on the pretreated textile surfac.
Surface pretreatment, and to a greater extent the polymer modifier used, largely determine the color fastness, fabric handle softness, and color reproduction faithfulness. Chavan and Hanif Langer [1] in their study on transfer printing of cotton fabrics suggested pretreatment of cotton polyester fabrics with a resin based on the reaction product of melamine formaldehyde with polyethylene glycol 200. This afforded good dye transfer and high wash and light fastness;
