This article presents research on the possibilities of creating value-added unconventional materials, functional fabrics and products from local basalt and basalt roving. Basalt fiber, i.e. roving, is used to make knitwear and heat-insulating cord. The thermal insulation cord was tested in the "SNOL 15/1200" electric furnace in the laboratory of the "Mega invest industrial" LLC joint enterprise and its durability up to +980ºС was determined.

In this article, the analysis of news on the development of the cotton industry in our republic is presented. In addition, based on theoretical studies and analyzes of cleaning processes used in foreign countries, ways to improve the cleaning efficiency of the pile drum, which is the main working organ of cotton cleaning equipment from small impurities. It is based on the need to carry out theoretical calculations of the cleaning surface to improve the cleaning efficiency of the cleaning equipment from small impurities. The results of the theoretical research on calculation of useful surfaces of mesh surfaces based on the calculation of the grid surface located in the lower part of pile barbars used in our Republic and abroad are presented. The need to develop new constructions to increase the use of mesh surfaces to 100% and its calculations were made.

“…If the speed of the air flow is further reduced, then after 18 m/s the particles of fibrous materials fall to the bottom of the pipe and move unevenly, bouncing. The results of monitoring the process of air transportation of fibrous materials showed that the raw materials are unevenly transferred to the pipes of pneumatic transport [5][6][7]. As a result, the cotton moves in separate sections in the pipe, somewhere concentrated, and somewhere in a rarefied state.…”

Uzbekistan is implementing comprehensive measures to produce a wide range of high-quality and inexpensive textile and light industry products based on the production and deep processing of cotton fiber, which is the main textile raw material, to prevent waste and increase its competitiveness. This article, to a certain extent, serves to implement the tasks specified in the Decree of the Cabinet of Ministers dated November 25, 2018 No. 53 “On additional measures to organize the activities of cotton and textile industries and clusters” and other regulatory and legal documents related to this activity. The science of cotton transport by pneumatic transport has a long history, and with an air flow speed of more than 28 m/s, cotton is distributed more evenly over the pipe section. In it, the transportation process is carried out mainly in the suspended state of the material. With a decrease in the air flow velocity from 25.0 m/s, an analysis of the literature on the uneven distribution of material over the pipe section was carried out. It has been practically proven that an increase in the expansion angle in expanding or contracting pipes depends on air resistance, and the expansion or contraction angle depends on the speed of air movement at the point of expansion or contraction of the pipe. Therefore, the optimal value of the angle of expansion or contraction of expanding or contracting pipes was determined.
