Abstract: In the work possibility of starch modification by phosphatic compounds and study of applying of obtained preparations, as thickeners in printing by active dyes on cotton fabrics is learned. Let's mark, that the degree of thickening is various for various concentrations of polymer and 4 % of masses reaches maximum rating for solutions with concentration of starch. It’s detected, that the effect of thickening starts at some extreme value of concentration of modifying agent. Temperature effect on rheological behavior of chemically treated solutions of starch is also investigated. The time of deformation relaxation of polymers is decrease with decreasing of characteristic viscosity, and, therefore, at the given degree of polymerization at a decrease of concentration of polymer in solution.
Key words: dynamic viscosity, modifier, yield point, degree of thickening, concentration, thickening.
