    [0001] The present invention relates to a method of manufacturing underwear, as well as undergarments obtained with such a manufacturing method, in particular brassieres. A known method of manufacturing an undergarment, in particular a bra for women, presented in particular by the document FR-A1-2850536, comprises the removal and the crosslinking of a layered shape memory material. thick on some parts of a textile piece, such as a silicone elastomer, and then shaping this textile piece by thermoforming.
    [0002] A cutting of the contour of the undergarment is then carried out, then the attachment of accessories if necessary, to obtain the finished product. Fine and very elastic textiles are generally used, which may include decorations such as embroidery. An undergarment is thus obtained comprising elastic zones 15 having predefined shapes, made by the shape memory material, which constitute reinforcements supporting certain parts of the body to give them a particular appearance. In this way, lightweight and stretchy bras are made in particular so as not to impede the movements of women, with hats providing the woman with a pleasant silhouette by effectively maintaining the breasts. In addition, in a known manner, is added to this process the bonding of a second textile on the first, enclosing inside the two thick layer of reinforcement deposited on certain parts, which then makes a bond between the two textiles . It is furthermore possible to supplement, apart from the elastic reinforcements, the bonding of the second textile to the first, with silicone spots deposited locally. However, the two tissues are not then fully secured, it is possible to obtain after thermoforming, especially if the reinforcing layer has been molded flat, folds of tissues that can be unpleasant to the contact, and unsightly. Rings can also give, especially if making ornamental designs on fabrics, a clutter that is not elegant.
    [0003] Moreover, if it is desired to obtain cut edges of the undergarment having a good cohesion, it is necessary to extend the thick silicone layer up to these edges, while the elastic reinforcing function does not necessarily require it.
    [0004] Moreover, in the case of a bonding of one fabric to the other by silicone points, these points can be visible and unsightly. The present invention is intended to avoid these disadvantages of the prior art. It proposes for this purpose a method of manufacturing an undergarment having two superposed textiles, comprising the removal on some parts of reinforcements comprising a thick layer of an elastic material with shape memory, the polymerization of this material as well as the forming the textiles of the undergarment by thermoforming, remarkable in that it comprises a step of depositing on the entire surface of at least one of the textiles, a thin layer of elastic bonding material, and then a step of polymerization of this thin layer of bonding during the forming thermoforming. An advantage of this manufacturing method is that the thin layer of the elastic material ensures a continuous bonding of the entire surface of the textiles 20 between them, which prevents the formation of creases. The shape of the reinforcements can be any, regardless of the decorations made on the fabric, which allows for underwear, including bras, with great nervousness while ensuring freedom of movement. In addition, it is possible to cut the contour of the undergarment in any places outside the reinforcements, which has a solid connection between the two fabrics which remains well ensured. This produces undergarments that can be very thin and transparent, highly decorated, while maintaining flexibility and exceptional nervousness.
    [0005] The manufacturing method according to the invention may further comprise one or more of the following characteristics, which may be combined with one another. In particular, the manufacturing method may include a step of polymerizing the reinforcing layer, before the polymerization of the thin bonding layer. In addition, the method may comprise steps of depositing several reinforcing layers on at least one of the textiles, after each polymerization of the previous layer. Variable thicknesses and elasticities of the reinforcement are thus produced depending on the location. In particular, the last reinforcing layer may be polymerized at the same time as the thin bonding layer during thermoforming. This gives a good cohesion of the bonding with the last reinforcing layer. The manufacturing process may comprise a preliminary step 15 on the textile receiving the reinforcing layer, a barrier layer of an elastic material, which is polymerized before the removal of this reinforcement. Advantageously, after the polymerization of the thin bonding layer during thermoforming, the method comprises a step of cutting the edges of the undergarment. Sharp cuts of the edges are obtained. The invention also relates to an undergarment having two superposed textiles having at least one thick reinforcing layer between them, which is produced with a manufacturing method having any of the preceding characteristics. Advantageously, the elastic shape memory material as well as the elastic bonding material is a silicone. This material has a good elasticity as well as a temperature stability. In this case, the silicone may have a hardness of about 30 Shore. Advantageously, the textiles have an elongation capacity of at least 125% in one of the directions. The textiles can thus follow the 30 movements of the person. The invention further relates to a bra formed by an undergarment comprising any one of the preceding features, which comprises at least one reinforcing layer in the lower part of the cups receiving the breasts. These inferior reinforcements provide effective breasts support and ensure their fitness. In particular, cutting the edge of the bra which is at the top of the cups, may not have a thick backing layer. We obtain a discreet appearance of this upper part which can be visible. The invention will be better understood and other features and advantages will appear more clearly on reading the following description given by way of example, with reference to the accompanying drawings, in which: FIG. 1 is a drawing of FIG. a bra having reinforcing zones, made with a method according to the prior art cited above; and - Figure 2 is a drawing of a bra made with a method according to the invention. Figure 1 shows a blank 2 which once finished will be cut out according to the final outer contour 4, and will then receive equipment to form a bra. The bra includes a piece of textile made of an elastic and lightweight material, made of a fabric of synthetic or natural fibers. The bra has cups 6 formed by thermoforming, 20 to receive the breasts of the woman and support them by giving them an aesthetic shape. Reinforcements 8 forming a thick silicone layer, are deposited on the complete outer contour 10 of the bra, on the central link 12 between the two symmetrical parts, and on the lower part of the cup 6 covering substantially a sector of about 900 whose center is the center point of this cap. A silicone with a medical grade is preferably used to avoid reactions with the skin, which is deposited at a thickness of between 0.5 and 1 mm, on the inside or outside of the tissue. The silicone is polymerized at a temperature between 150 and 200 ° C, for example in an oven, with a heat press, or infra-red radiation. The cups 6 are then thermoformed in a mold to give a configuration to the tissues and to obtain the final shape. Figure 2 shows a brassiere according to the invention which is entirely finished, further comprising straps 20 and stapling means in the back 22. The elongation of the silicones used for the reinforcements 8 may be about 600% before breaking, textiles with a large elongation, which is preferably at least 125% in one direction, and if possible more than 125% in both directions, are used to follow the deformation of these reinforcements. . In particular, a two-component silicone can be used. A method of manufacturing this bra is as follows. The silicone forming the reinforcing layer 8 is deposited in a thickness advantageously between 0.1 and 3 mm, on the side of a first so-called inner textile part 15 intended to bear against a second textile part. This deposit can advantageously be made according to a precise drawing by a screen-printing process, comprising the laying of a fine grid comprising partially open openings according to the zones of reinforcement to be produced, then the sliding of a squeegee on this grid in a manner that is to force the passage of the material lying on it, through the openings. With this screen printing process, in particular, an impregnation of the silicone in the textile is obtained, which increases its nervousness, that is to say the restoring force in its initial position. At the same time, a thin layer of silicone is deposited on the complete inner face of the second textile part, which is advantageously between 0.005 and 0.1 mm. In particular for these layers, a silicone having a hardness of about 30 Shore is well suited for bras applications. The two textiles are assembled by placing the inner faces comprising their silicone layers in abutment with one another. This set is then placed on a mold for shaping the cups, and the mixture is cooked so as to simultaneously effect a crosslinking of the two layers, and a shaping of the textiles by thermoforming. Equipment such as straps 20 or stapling means 22 can be attached at the same time during the polymerization, or reported thereafter. Thus, after the cutting of the contour 4, a particularly homogeneous finished product is obtained, the two textiles being bonded together on all their surfaces, while keeping a very great flexibility. In particular, it is possible to make an edge 24 of the brassiere at the top of the cups 6 which is very thin and almost transparent because it does not have a thick reinforcing layer. We can also realize a very elaborate decor on the lower part of the cups 26, which will not present any frills, which preserves the aesthetic aspect of this decor. The synthetic or natural fibers of the fabrics may be especially polyester, polyamide, cotton, modal or viscose. Note that the thin layer of bonding can provide better resistance to thermoforming materials based on natural fibers, which usually do not lend themselves to this operation. As an alternative to this process, a temperature polymerization of the silicone of the reinforcing thick layer 8, deposited on the first textile, which is carried out flat or in a first form, can first be carried out. The second textile having its thin and complete bonding layer is then deposited on the first textile and the assembly is placed on the mold giving the final shape. Then by heating in the oven, at the same time the textiles are thermoformed, and the thin layer of silicone adhesive is polymerized. In addition, several reinforcing layers 8 can be deposited on one or both of the two fabrics, each time with polymerization of the previous layer. The layers are partially superimposed in order to obtain thickness variations of this reinforcement having elongation and jitter characteristics that vary according to the locations.
    [0006] The final polymerization of the thin bonding layer and the thermoforming of the textiles can then be done with the last reinforcement layer already polymerized, or at the same time as the polymerization of the latter layer.
    [0007] It will be noted that the crosslinked silicone being insensitive to the temperature, the firing to effect the bonding does not modify the thick layer of silicone reinforcement which is already polymerized, and in particular the shape which is already given to it. The undergarment thus has a very good resistance to washing in temperature thanks to the inertia of the silicone, its shape as well as its elasticity remain constant. In particular, the adhesive silicone deposited in a thin layer can be transparent, which makes it possible, with very light textiles, to obtain zones that are almost transparent. Alternatively, a colored silicone can be used to achieve certain aesthetic effects.
    [0008] In addition, the method may comprise the removal on the textile receiving the reinforcing layer 8, of a barrier layer before the laying of this reinforcing layer. The barrier layer constitutes, after its polymerization, a protection which makes it possible to maintain the reinforcement layer 8 remaining wet on the textile during handling before its final polymerization. This avoids a flow of wet silicone through the textile, particularly for textiles with drawings having large openings.
