THE STUDY OF THE RHEOLOGICAL PROPERTIES OF THE THICKENING POLYMER COMPOSITIONS AND INK-BASE PRINTING

The article describes the research results about the dependence of the viscosity of the concentration system of bentonite and it was found that bentonite K-4: HAE = 1 : 0.05 : 0.2 provides stable structures with the required dynamic viscosity in case of having optimal components.The influence of the concentration of the alkaline agent and the holdup time of the active dyes on the degree of fixation was revealed during the research.Along with this it was found that the degree of fixation of active dyes when printing using a thickener has not been reduced and in contrast it was higher by 10-25% than when using existing thickeners.The structural-mechanical and rheological properties of the developed polymer systems were carefully studied and revealed a deeper penetration of printing inks into the fabric, compared with printed inks thickened with sodium alginate.
