FIELD: medicine; hygienic aids. ^ SUBSTANCE: diaper has front and back belt parts, gusset, and pair of first and second wings. Pair of second wings is made of composite sheet being subject to elastic extension. The sheet has air-proof polymer film with multiple ventilation channels, which have first opening turned to patient's skin, and second opening turned from patient's skin. Air-proof layers of unwoven fibrous material, subjected to thermal welding, are partially connected with both surfaces of polymer film and they are formed to have multiplicity of folds, rising and going down along surfaces of layers of unwoven material. Second opening has area being smaller than area of first opening. It is made in such a way that ventilation channel should get narrower from first opening in direction to second opening. Fibrous unwoven layers are connected inside ventilation channel in points of welding. Number of ventilation channels, inside which channels the layers of fibrous unwoven material are connected one to another, belongs to 1,5-10% range. Diaper is made in such a way to make user not to feel any discomfort and to allow water vapors, generated during sweat evaporation process, go out of diaper through wings. ^ EFFECT: higher comfort at use. ^ 6 cl, 11 dwg |
