FIELD: process engineering.
SUBSTANCE: invention relates to light industry, particularly, to combined material - laminate. Proposed material comprises textile web and PEU membrane formed on web wrong side by coagulation of PEY composition. Membrane is formed on web wrong side to 0.03-0.04 mm thickness from the following composition, in wt %: PEU solution with content of dry substance of 23-25% - 100.0; surfactant - 0.2-0.4; di-(2-ethylhexyl)-phthalate - 0.8-1.5; dimethyl formamide - 6.5-7.5 with dry substance weight increment of 60-80 g/cm2, thickness of 0.03-0.04 mm and layer weight ratio of 0.504-0.77:023-0.496.
EFFECT: higher water resistance, better hygienic properties.
