SUBSTANCE: invention relates to a light industry and can be used in manufacture of clothes, shoes, hats and decorative items made of felt as well as at for felt products restoration. The method includes forming a canvas by stacking layers of wool fibers and applying on the layers of wool fiber of textile material, felting, felling and drying. On the canvas from the side of textile material the layers of wool fibers are additionally placed. After felling the moulding is carried out, and after drying - wet-heating treatment. Wet-heating treatment is carried out under pressure at a temperature of 120-150° C, corresponding to a temperature of adhesion of adhesive. As textile material the easily mouldable adhesive gasket material with sparse structure is used. The adhesive gasket material can be placed in accordance with the zones marked on the detail.

EFFECT: reduction of thickness and weight of felt parts is provided, while maintaining the specified strength; obtaining one-piece moulded detail with uniform thickness, with zones which differ in properties; increasing the strength of the obtained material; preservation of appearance of felt on the front and reverse side of the product which is attractive for a consumer.
