In this article, funds in the field of labor protection, the use and direction of funds are analytically studied, and the role of these funds in the economy of the enterprise, region and republic is analyzed.

The article presents the results of laboratory studies of the physical and mechanical properties of saline, poorly bound soils, which are studied during soil washing. The specific characteristics of saline poorly bound soils in leaching are shown, in which special attention is paid to the processes of mechanical and salt dissolution suffusion of soils.

These articles present the results of scientific research on existing problems and their elimination in order to create safe and healthy working conditions in the production sector. The article also contains a scientific proposal formulated by the author and practical recommendations on this issue.

As a result of the conducted research, it was determined that for 5LP linters, it is necessary to produce a saw cylinder that increases the productivity of the linter in terms of seed and fluff, reduces electricity consumption, improves the quality of seed and fluff after the linter, and does not have a high vibration level during the rotation of the saw cylinder.

Detailed information on fibers used in the production of leather goods, classification of materials, proximity and similarity to the composition of fibers, molecular composition and physical and chemical properties. Also, the molecular structure and properties of natural and chemical fibers are explained in this state.
