Abstract
It is shown that improving the safety of miner’s suits is associated with the development of theoretical concepts of physical processes in textile materials. The current understanding of the passage of dusty air through a textile material does not always ensure the safety of miner’s suits. It has been established that one of the ways to solve this problem is to build and use digital twins of the processes of dust permeability of textile materials. The mechanisms of dusty air passage through a textile material are analyzed, a model of dust movement in the air flow in the immediate vicinity and structure of the textile material is proposed. A mathematical model of dust particle capture by structural elements of the fabric is compiled. Based on these ideas, a numerical model of dust permeability of a textile material is compiled, its solution is obtained using the example of fabric, an example of using the modeling results in calculating the dust permeability and dust capacity of textile materials is shown.
