Undergarment receiving a thin intermediate bonding layer between two textiles prior to thermoforming
A process for manufacturing an undergarment having two superimposed textiles, comprising depositing on certain parts of reinforcements ( 8 ) comprising a thick layer of a shaped memory foam elastic material, the polymerization of this material and also the shaping of the textiles of the undergarment by thermoforming, characterized in that it comprises a step of depositing, on the entire surface of at least the textiles, a thin layer of an elastic adhesive-bonding material, and then a step of polymerizing this thin layer of adhesive bonding during the thermoforming for shaping, and in that it comprises a step of prior depositing, on the textile receiving the layer of reinforcement ( 8 ), of a barrier layer of an elastic material, which is polymerized before the depositing of this reinforcement.
1. An undergarment, comprising:
two layered textiles comprising between them at least one reinforcement layer, the at least one reinforcement layer comprising a polymerized elastic shaped memory foam material,
a layer of a polymerized elastic bonding material over a full surface of at least one of the two layered textiles, and
a barrier layer of a polymerized elastic material deposited on a first layered textile of the two layered textiles between the at least one reinforcement layer and the first layered textile.
2. Undergarment according to claim 1 , wherein the elastic shaped memory foam material and the elastic bonding material comprise a silicone.
3. Undergarment according to claim 2 , wherein the silicone has a hardness of about 30 Shore.
4. Undergarment according to claim 1 , wherein the textiles have a stretching capacity of at least 125% in one direction.
5. The undergarment of claim 1 , wherein the undergarment is a brassiere, wherein the at least one reinforcement layer is positioned in a bottom part of cups of the brassiere, the cups of the brassiere configured to hold breasts of a wearer of the brassiere.
6. The undergarment according to claim 5 , wherein a cutout of an edge of the brassiere that is located on a top of the cups does not include the reinforcement layer.
7. The undergarment according to claim 2 , wherein the silicone forming the reinforcement layer is deposited according to a thickness between 0.1 mm and 3 mm, and the layer of elastic bonding material is deposited according to a thickness between 0.005 and 0.1 mm.
8. The undergarment according to claim 3 , wherein the textiles have a stretching capacity of at least 125% in one direction.
9. The undergarment according to claim 4 , wherein the textiles have a stretching capacity of more than 125% in both a lateral direction and a longitudinal direction.
10. The undergarment according to claim 1 , wherein the at least one reinforcement layer comprises a thickness between 0.1 mm and 3 mm.
11. The undergarment of claim 1 , wherein the layer of polymerized elastic bonding material comprises a thickness between 0.005 and 0.1 mm.
