The speed of sound in a porous cotton medium is 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, is disclosed. A generalized equation is obtained that describes the force stress in a cotton medium when exposed to a variety of shapes of working bodies of cotton machines. A method for calculating the damage to seeds and cotton fibers in the process of interaction with the working bodies of processing machines is proposed.In the process of processing raw cotton or cotton fiber, the fibrous mass is sharply mechanically affected by organs on the work of organs in the area of inflammation or disease, while complex processes occur inside the fibrous mass associated with a change in the measurement of density and pressure in it. Stresses in the fibers in the presence of conditions of high density of body mass, which can be manifested by plastic deformation, shortening of the fibers and severity of quality. The derived theory for the stress state of cotton raw materials in the process of processing allows to use it practically in all important issues of describing the damage of fiber and cotton seeds in the technological operations of primary processing of cotton ER -
