SUBSTANCE: invention relates to composite materials for disposable absorbing articles used for moisture-absorbing and waterproof breast stomatological aprons, coverings, surgical aprons, bandaging facilities, and the like. Composite material consists of two layers: one layer is made in the form of fibrous layer containing thermoplastic synthetic fibers and the other in the form of microporous vapor-permeable and moistureproof film based on thermoplastic polymer. The layers are glued to each other locally by partially fused film polymer and polymer of thermoplastic fibers belonging to fibrous layer. The latter additionally contains 5 to 50% of cellulose-based fibers and surfactant preparation based on sorbitan derivatives selected from group: sorbitan-bis(polyoxyethylene) monooleate (Sorbital O), sorbitan-bis(polyoxyethylene) monostearate (Sorbital C), and pentaerythritol stearate polyethylene glycol ether in amounts 0.5 to 5 % on the dry weight.
