The monograph discusses the features of the chemical composition, structure and properties of wool fibers and polyester. An analysis of the properties of textile materials made of wool and polyester fibers affecting the molding ability of the material is presented . Modern methods of modifying textile materials are considered, the possibility of plasma processing of textile materials from wool and polyester fibers is substantiated in order to improve their molding ability. The description of the experimental plasma installation of the HSE discharge, the objects of research and their characteristics is presented. Methods of conducting experimental studies. are described The results of experimental studies of changes in the mechanical, physical, chemical and structural properties of modified textile materials from wool and polyester fibers by the low pressure plasma flow . A technological process using plasma processing is proposed to increase the form-forming and fortifying ability of textile materials made of wool and polyester fibers .
