Waterproof "breathable" membrane materials were obtained using acrylic emulsion for the polymer layer and cotton terry cloth for the textile layer. Excellent physical, mechanical, and hygienic properties of polymer-textile materials obtained by spraying the emulsion on the wrong side of the terry cloth, allow them to be used for medical and prophylactic bed linen. The resulting materials absorb a large amount of water (350%-366%), at the same time do not let liquid water through (water resistance-395-470 mm H 2 O), but have sufficient air and vapor permeability. The water-absorbing and membrane properties of the obtained materials are due to their nature (hydrophilicity of cellulose fibers, hydrophobicity of polymethylacrylate) and structure (terry weaving of a textile fabric, the presence of micropores). Scanning electron microscope studies of the surface and cross section showed the capillaryporous structure of the polymer layer and the material as a whole. When spraying an acrylic emulsion, a continuous polymer film is not formed; a hydrophobic polymer layer is located on the surface of individual fibers of a textile fabric. Another important advantage of the obtained membrane materials is that their water absorption, water resistance, and "breathing" properties are preserved after repeated washings.
