Abstract: This article discusses the development of new and improved traditional methods for obtaining thickening components for packing. It was found that the introduction of polymers such as Na – CMC and sericin into the thickener of printing inks-modified starch leads to the formation of a film with increased elasticity and fluidity. It was determined that the results obtained by the recommended composition are almost close to alginate thickeners in terms of the stability of colours to wet treatments, their intensity, strength to friction and stiffness of the printed fabric, but in almost all indicators they are superior to thickeners based on modified starch. The expediency of using printing inks based on such thickeners is due to the exclusion of interaction of chromophore anions of the dye with functional groups of polymers, the presence of an alkaline agent in the composition that serves as a thickening activator and creates a medium for the formation of a covalent bond between the dye and the fibre. It was found that printed cotton fabric with active dyes based on starch thickener does not sufficiently provide resistance to dry friction (2 points) and gives the printed fabric increased stiffness (6.7 times). To eliminate these shortcomings, in addition to modified starch and CMC, a sericin solution was introduced into the composition of the recommended printing composition, while the hardness index (2.7-6.7 times) is almost reduced to the level of the alginate thickener (1.8 times), (changes in the range of 0.2-1.1). If the quantitative ratio of the components that make up the composition is observed, the fabric stiffness is reduced, bright and durable colours are obtained, and the degree of fixation of active dyes is up to 95-96%. It was determined that the value of the amount of desorbed active dye in the process of intensive washing of printed fabric mainly depends on the number of components of Na-CMC and sericin that are part of the composition. Due to the use of the developed composition as a thickener of printing inks, it is possible to reduce the consumption and cost of chemical materials and increase environmental safety when working with textile and finishing enterprises
