This article examines the issue of increasing fiber yield and quality in cotton ginning plants from the perspective of the interrelationship of technological processes. The study analyzed the effects of cotton raw material moisture, dirtiness, drying and cleaning regimes, the ginning process, and lint cleaning stages on fiber yield and quality indicators. An analysis of the scientific literature shows that maintaining fiber moisture content during ginning is an important factor in maintaining fiber length and reducing the proportion of short fibers. USDA studies have shown that a fiber moisture content of about 6–7% for ginning is optimal from the point of view of maintaining quality, but for cleaning efficiency, a range of 5–6% may be preferable under certain technological conditions. The article compares the performance of three different technological regimes based on a conditional experimental model. According to model calculations, by combining optimal moisture, stepwise cleaning and ginning regimes, there is a possibility of increasing fiber yield by 1.0–1.5 percentage points, reducing the share of short fibers and improving fiber length. The results of the study indicate the need to implement real-time monitoring and control systems of technological parameters in cotton ginning enterprises.
