FIELD: process engineering.
SUBSTANCE: invention relates to multilayer combined materials. Proposed material comprises: top layer of textile web with porous polymer layer applied on its wrong side, adhesion layer and bottom layer. Porous polymer layer is formed on said working side and consists of the following components in wt %: polyesterurethane - 92.08-94.84; dimethyl formamide - 0.759-1.106; surfactant - 0.759-1.106; di-(2-ethylhexyl)phthalate - 0.759-1.106; microcrystalline cellulose - 2.884-4.604. Said composition is diluted by dimethyl formamide to viscosity of 170-180 poises.
EFFECT: optimised thermophysical and hygienic properties.
