Cotton in the article has high humidity and pollution The technique and technology of initial processing of dirty, especially machine-picked cotton, processes of separation of impurities from the moving particle composition are considered. Keywords: cotton, cotton wool, model, pollution, fibrous waste. Introduction. Globally, it is more important to improve the pre-treatment techniques and technology of cotton with high humidity and pollution, especially machine-picked cotton, to develop the theoretical basis of the processes of cleaning cotton from small and large impurities, to justify the movement parameters and working modes of working parts and mechanisms, through which cotton can be cleaned and cleaned. extensive theoretical and complex experimental studies are being conducted to determine the optimal values of geometric and kinematic dimensions that provide At the same time, ensuring the effectiveness of cotton cleaning and maintaining the initial quality indicators of the product, including creating mathematical models that allow choosing the optimal modes of cotton cleaning that do not negatively affect the quality of the product, and reducing the strong shock effects when cleaning cotton from dirt and impurities, developing soft mode technologies of cotton cleaning. output, creating constructions of resource-efficient working bodies of cleaners is becoming important. In our republic, comprehensive measures are being implemented to improve the techniques and technologies of cotton industry enterprises and technical re-equipment, to increase the profitability of cotton raw material processing and the competitiveness of manufactured products. In 2017-2021, the Strategy of Actions for the further development of the Republic of Uzbekistan, including the task of increasing the competitiveness of the national economy, reducing the consumption of energy and resources in the economy, and widely introducing energy-saving technologies into production, is defined. In the implementation of these tasks, including the improvement of the technology of initial processing of cotton, in particular, the development of an effective technology for separating impurities from its content by cleaning it before storage, and the development of a rational arrangement of working bodies that ensures high cleaning efficiency, soft impact regimes based on the determination of the trajectories of the working bodies and cotton components in cotton cleaning. 317 Acumen: International Journal of Multidisciplinary Research Acumen: International Journal of Multidisciplinary Research ISSN: 3060-4745 IF(Impact Factor)10.41 / 2024 Volume 1, Issue 4 Materials and Methods.
