“…53 of November 25, 2018 "On additional measures to organize the activities of cotton and textile industries and clusters" and other legal documents related to this activity [1]. Air tubes are used in most of the primary processing of cotton, resulting in the loss of fibers and fibrous materials in the tubes [2]. At present, the cotton ginning industry needs to take urgent measures not only to improve the technological process of receiving, storing and preparing cotton for processing, drying, cleaning and processing, but also to improve cotton air transport systems [3,4].…”

In the world, one of the main tasks is to improve the quality of cotton and products from it, the introduction of energy and resource-saving technologies and technical means at enterprises, which make it possible to reduce their cost. In the priorities of the Decree of the President of the Republic of Uzbekistan dated January 28, 2022 No. PF-60 “New Development Strategy of the Republic of Uzbekistan for 2022-2026”, the third priority area called “Advanced development of the national economy and ensuring high growth rates” clarifies the inclusion of a number of tasks in the state program. Air pipes are used in most stages of the primary cotton processing process. In this direction, a scientific base is being created to improve the efficiency of the process of transporting fibrous materials by air, special attention is paid to improving product quality and reducing costs through the creation of automated pneumatic transport systems, and the widespread introduction of modern pneumatic equipment and technology into production is accelerating. Although many studies have been done on the loss of fibrous products during the air transport of cotton and cotton products, some fibrous material is released into the atmosphere. To prevent this, it is necessary to determine the aerodynamic resistances that form in the areas of the changed surface of pneumatic transport pipes, and develop recommendations for their reduction. In this article, based on the results of theoretical and practical studies, local resistances are determined in the zones of narrowing of air pipelines of pneumatic transport, and the change in air speed is presented in graphical form.

This study aimed to improve the quality indicators of cotton by replacing traditional steel pipes with polyethylene pipes in cotton ginning enterprises. The research involved adding erucamide product to the polyethylene composition and applying it to the cotton ginning process. The damage processes to cotton fibers during the seed cotton flow action in pneumatic steel pipes were studied. The installation of polyethylene pipes was found to significantly improve the quality of the chipboard. The advantages and disadvantages of using polyethylene pipes were considered, and the damage levels to cotton fibers were assessed. The results highlight the benefits of using polyethylene pipes in cotton ginning enterprises to produce high-quality cotton fibers and seeds.

We focus in this review on the pre-processing devices used, the cotton pipeline, the rejection system, the acquisition and processing of information from images of raw cotton, and measurements of the rate of dynamic flow of the cotton stream. The results show that raw cotton fluffs into a material with a more uniform thickness, and adequately separating the cotton bunch can improve the subsequent detection and removal of foreign fibers in it. Moreover, research that combines the structure of the cotton pipeline with the optimization of the structure of the nozzle plate is important for improving the rejection of foreign fibers in cotton. Furthermore, a combination of multiple light sources and arrays of charge-coupled device cameras can improve the quality of images of raw cotton, but such key parameters as the power and wavelength of the source of light need to be optimized. As any single algorithm for image segmentation and feature extraction struggles to adapt to the identification of different kinds of foreign fibers, it is important to explore a combination of algorithms to this end, and to develop new techniques of foreign fiber detection based on deep learning. Finally, the structure and parameters of processing of the system for the identification and removal of foreign fibers are important, including the relative distance between the sensor and the nozzle, the width of the detection channel, and the rate of flow of the cotton stream.
