Preparation of textile materials for dyeing and printing

The article presents data on the development of technology for the preparation of cotton fabrics for subsequent coloring processes and final finishing. Improving the quality of products in the process of preliminary preparation of fabrics is associated with the development of highly efficient technologies using textile auxiliaries, new chemical and physical methods for intensifying ongoing processes. Technologies have been developed for the preparation of cotton fabrics aimed at obtaining the required level of physical and mechanical characteristics of materials. The optimal parameters for the preparation of technological solutions, concentrations of chemicals, the ratio of components in the solution, temperature and duration of the process were selected. The qualitative parameters of the treated tissue, capillarity, degree of whiteness, and discontinuity characteristics were studied. A periodic and continuous method of preparing cotton fabrics is proposed, ensuring the removal of non-fibrous impurities from harsh fabrics, which will improve the quality of the treated fabric by increasing capillarity and whiteness, reduce energy consumption and duration of the process. The obtained research allows us to build modern and promising, economically justified technological processes for the preparation of textile materials made from natural, chemical fibers and their mixtures.
