Abstract
The article is devoted to methods of determination of physical - mechanical properties of membrane materials, nonwoven insulators and clothing package in general. The standard known methods and methods of research are described, as well as the influence of operational and production factors on the structure and properties of membrane tissues that form packs of clothing materials. The physical and mechanical properties of membrane tissues to abrasion in the plane have been investigated, tensile to fracture, elongation, indestructibility, vapour permeability, water resistance, thermal conductivity, breathability. The article presents a reasonable selection and characterization of research objects, materials that form packs of heat-resistant clothing: top tissues - membrane fabrics, insulation - nonwoven volumetric insulation, lining and auxiliary materials and developed packages of heat-proof clothing.
