Abstract

The article provides an analysis of the proportions of different selections and industrial varieties, harvest type in terms of size and number of pollutions in the cotton. The problem of the formation of the force of binding of pollutions with the fiber was analyzed, and it was suggested that the main reason was the adhesion of the fiber to the bumps formed along the perimeter of the pollution. The experiments are based on the fact that the contamination and the contamination of cotton determined on the basis of cotton weights are the same, but their proportions are different in size. The possibility of separating fine pollutions in the cotton from the pile drums used in ginning plants was studied, and it was found that they can extract up to 93% of the total fine pollutions. Based on the comparative analysis, it was found that there is a significant difference in the weight and number fractions of pollutants by size. The effects of cotton selection and industrial variety, initial contamination, harvest type on the proportions of pollution by size. It was noted that the determination of cotton pollution by their weight ratio does not fully characterize cotton as an object of ginning, and on this basis there is a need to reconsider the issue of determining the plan of ginning of cotton based on the initial pollution.
