Abstract: A multi-ply technical composite, usable in particular for making medical aids, garments and medical articles, includes at least two layers (2, 3), the first of which (2), in contact with the skin, is a cotton fabric (elasticised to a greater or lesser extent) or silk, or fabrics to which chitosan, silver or another antibacterial substance or active constituent is added, and the second, outer layer (3) is constituted by a semipermeable membrane, such as polyurethane between 5 and 80 microns thick, with considerable elasticity in order to ensure the user's comfort. Receptors rechargeable with active constituents are inserted into fabric (2) and protected by the polyurethane membrane.

Abstract: Semimanufactured waterproofed products (1), particularly shoes, clothing items and accessories, are provided having a three-dimensional conformation with at least one inner surface (2) and one outer surface, provided by the following operative steps: turning inside out the semimanufactured product (1) so that its inner surface (2) is turned outwards; inserting at least one shaped member (4; 8) inside the semimanufactured product (1); pressing the semimanufactured product (1) provided with the shaped member (4; 8) between at least a pair of sheets (5) of a semi-permeable membrane whose surface turned toward the semimanufactured product (1) turned inside out is provided with a glue pattern; and turning the semimanufactured product (1) so that its inner surface is turned inwards.
