The article covers the results of research conducted on production of fabrics of various blended composition, such as local wool + cotton + polyester and cotton + cattail, in order to develop a new assortment of costume fabrics of various compositions. The production of such costume fabrics did not require the replacement of technological equipment, only the equipment was partially improved in order to settle the new assortment of production fabrics. The model for knitting costume fabrics of various compositions that gives positive results has been developed.

“…Percentage of impurities in the raw material during and before the wool loosening process has been studied. Accordingly, it has been determined that coarse wool contains 20-32% of impurities, and 10-16% of all impurities are separated during the loosening process [13][14][15].…”

The article covers natural wastes emitted from wool in the loosening process. The results of experimental research of the amount of ecologically clean fiber are shown. Analytical research of scientific and technical information about technologies and technical means of primary processing of wool, as well as previous research in this area has been carried out. Improvement of the technological parameters of machines for loosening wool by adapting them to the characteristics of local wool has been studied. The dependence of the separation of contaminants from the composition of wool on the design of the fire bar of the fire grate of the column structure and the density of the product in the working chamber has been determined. Based on the results obtained, it has been determined that the use of an improved wool loosener improved cleaning efficiency. It has been determined that during the testing process, an experimental sample showed high performance. It was determined that after the peg drums, the porosity of the wool doubled, and the density of the wool decreased by half. The development of a new design of a loosening machine for loosening and cleaning wool fibers has been shown in technological schemes.

“…In this case, the hot air does not dry the cotton pieces, but also makes them move faster. Therefore, the effect of the coefficient К m , which represents the airflow speed and movement, on the movement of cotton pieces was studied [24]. The laws of motion representing the effect of hot air flow on the speed of movement of cotton raw material along the surface of the screw are shown (Figure 3).…”

The article covers the principle of operation, as well as the results of theoretical research of the improved technology of the screw mixer-feeder unit of a new construction for the drying drum that allows the initial mixing of cotton raw materials with hot air and improves the ecological stability of the environment. The forces acting on the cotton pieces during the drying process have been determined. The graphs of the dependence of the amount of moisture release on the speed and density of hot air at different temperatures during the drying of cotton raw materials have been obtained. The laws of movement of cotton pieces in the screw conveyor along the surface of the screw have been theoretically substantiated.
