Research on the Method for Determining the Interaction of Cotton With the Working Bodies of Cotton Gins

A theoretical regularity of the general behaviour of raw cotton as a porous medium in the technological processes of its mechanical processing has been substantiated for the first time. The speed of sound in a porous cotton medium has now been determined. The effect of additional force stresses inside the cotton medium caused by the filtration of the air component from cotton raw materials during the introduction of the working body, has been disclosed. A generalized equation that describes the force stress in a cotton medium when exposed to a variety of shapes of working bodies of cotton machines has been worked out. A method for calculating the damage to seeds and cotton fibers caused by their interactions with the working bodies of processing machines has been proposed.

The resultant theory that describes the stress state of cotton raw materials during processing allows us to use it practically to solve all important issues pertaining to the damage of fiber and cotton seeds that occur by using technological solutions in primary processing of cotton operations.
