Abstract: A process for thermo-adhesive bonding of semi-finished products includes preparing an inner sock, an outer sock and an impermeable membrane provided with a thermo-adhesive disposed on an inner surface and/or an outer surface of the membrane; fitting the inner sock onto a rigid reference shape; fitting the membrane over the inner sock; fitting the outer sock over the membrane; heating the outer sock, the membrane and the inner sock arranged on the rigid reference shape in an oven until at least partial melting of the thermo-adhesive; cooling the outer sock, the membrane and the inner sock arranged on the rigid reference shape until cross-linking of the thermo-adhesive and stable bonding of the membrane to the outer sock and/or the inner sock. Also, exerting a substantially uniform pressure on the outer sock, the membrane and the inner sock disposed on the rigid reference shape during cooling, so as to compact them.

Abstract: A knitted semi-finished product for manufacturing stockings, footwear and gloves, comprises: a main waterproofed portion configured to contain a user's foot or hand. The main waterproofed portion comprises an outer knitted portion and an inner waterproofing portion configured to prevent the passage of liquids from the outside to the inside of the semi-finished product. An auxiliary knitted portion is connected to the outer portion and delimits an opening configured to receive the user's foot or hand. A ring-shaped portion belonging to the auxiliary knitted portion and directly connected to the outer knitted portion has a lower hydrophilic characteristic than a hydrophilic characteristic of the outer knitted portion, so as to stop or at least slow down the capillarity rise of the water absorbed by the outer knitted portion.
