NEW PRODUCTION TECHNOLOGY OF FINER YARN MIXED FIBERS POLYESTER AND MEDIUM FIBER COTTON FOR THE TEXTILE INDUSTRY

Abstract

The article is devoted to the synthesis of ethylene glycol and dimethyl terephthalate based on local raw materials used for the production of polyethylene terephthalate, the dry forming of fibers from existing polyethylene terephthalate granules, and the production of high-quality yarn from a blend of cotton and polyester fibers. According to the results obtained, active and selective catalysts based on zeolite and bentonite for the synthesis of p-xylene have been recommended, as well as the composition of the dyeing bath enabling to achieve highly intensive and soap proof coloring on polyethylene terephthalate fibers. A technological mode for producing high-yarn of polyester and medium-fiber cotton has been developed.
