abstract

Waterproof clothing must remain protective throughout its life. But in the course of operation, waterproofing materials are subjected to mechanical loads of low intensity. Under the influence of stretching, compression and bending, fatigue phenomena in the structure of the material accumulate, the bonds between the elements of the structure are weakened, and the material is destroyed in the places of the most frequent application of loads.

The article is devoted to the study of the structure of waterproofing materials with a polyetherurethane membrane and the evaluation of the effect of mechanical operating loads on the parameters of the structure of materials of various types.

Analysis of the results of the study will help manufacturers of clothing from membrane materials to implement a sound selection of materials, increasing the durability of products.
