ABSTRACT Functional polymer–textile materials with membrane properties were developed using an acrylic emulsion and six types of textile substrates. The emulsion was applied onto the textile base by spray coating in two or four layers. Polymethylacrylate contained in the emulsion formed a microporous structure on the reverse surface of the fabrics, ensuring adhesion to individual cellulose fibers. Due to the hydrophilic nature of cellulose, the textile substrate exhibits high water absorption capacity. At the same time, the small size of the interfiber pores, together with the hydrophobic character of the polymer phase, provides resistance to liquid water penetration. However, air and water vapor molecules are able to pass through the microporous structure, allowing the fibrous–polymer layer to function as a breathable membrane. The terry fabric with double‐sided pile demonstrated a high water absorption capacity (438%–475%), whereas the single‐sided pile material exhibited high water resistance (400–448 mm H 2 O). The material based on polyester fabric has low water absorption and water resistance, but high air permeability. The cotton–polyester knitted fabric maintained high water absorption after treatment. The interaction between the components of the composite materials and their structural changes were analyzed using TGA, DTA, and SEM.
