ARTICLE ANNOTATION

quote
The article discusses the theoretical foundations of cotton and fiber moistening techniques and technologies, the properties of cotton as a moistening object, moistening agents, the moistening technology and techniques, and the influence of moistening points on the moistening process in technological operations. Based on a theoretical analysis of cotton and fiber, formulas are recommended for determining the water consumption used for moistening and characterizing the kinetics of moistening. The laws of motion during pneumatic transfer of a drop of water with condensation onto the surface of cotton, the conditions for its movement from the surface of the fiber or movement along the surface, as well as the relationship between air speed, drop diameter, mass and time of separation of the drop from the surface were obtained. Although at a number of stages of the technological processes of cotton ginning enterprises many methods have been developed for moistening cotton and fiber, the reasons have now been studied that the fiber is moistened mainly after the cotton ginning process, in the condenser tray, but despite this, plastic hard layers and yellow spots remain in the fiber bales supplied to the spinning mills, recommended moisturizing points and optimal moisturizing agent. The theoretical foundations of the cotton moistening process are considered. Using the formulas for the condensation coefficient, critical cooling of steam and humidification efficiency, the amount of steam that can be used for humidification is determined.
