It is known that active dyeing dyes create a strong covalent bond in the fiber, but are hydrolyzed in an alkaline environment and lose the property of covalent bonding to the fiber. Electrolyte increases the efficiency of sorption of the dye on the fiber surface and increases its aggregation in the solution. The results of the research showed that when two types of electrolytes NaCl and Na₂SO₄ were studied at different concentrations, the degree of binding of the dye to the fiber was high at the NaCl concentration of 20 g/l, the utilization rate of the dye was 83.5%, and the color intensity index was 6.6. Based on the study of the effect of the alkaline agent, at a concentration of Na₂CO₃ of 2 g/l, the utilization rate of the dye was 79.2%, and the color intensity index was 7.0, so these concentrations were considered acceptable.</p> D.

According to experts, it is an urgent issue to reduce the factors that negatively affect the environment and human health through the processing of natural resources, as well as to offer economical and economically efficient technologies for humanity. Currently, there is a significant shortage of fiber semi-finished products for the cellulose and paper industry of the Republic. The use of semi-finished products imported from abroad causes an increase in the cost of finished products and, as a result, a decrease in the competitiveness of this product and the profitability of production. The purpose of this research is to solve the problems of removing color and increasing the whiteness of the fiber by separating the dyes and impurities from it, while maintaining the quality of the fiber. Based on the conducted studies, it was determined that the degree of polymerization of the waste paper mass decreases with the increase in the concentration of the oxidant. Oxidizers first affect the functional groups located on the surface of the cellulose fiber, and then slowly penetrate into the fiber. By deliberately choosing oxidants, it was determined that a particular functional group in the molecule can be oxidized, based on its reactivity, and the conditions for the process were proposed.</p> Anvar Abdumajidov Abduamlik Miratayev Copyright (c) 2024 Web of Scholars: Multidimensional Research Journal https://creativecommons.org/licenses/by-sa/4.0 2024-04-17 2024-04-17 3 3 1 7 10.17605/wos.v3i3.1998
