DETAILED DESCRIPTION

[0028] Various aspects of the present application will be described in detail with reference to the drawings in order to better understand the present invention. It should be understood that the accompanying drawings and the detailed description describe only exemplary embodiments of the present invention, and are not intended to limit the scope of the invention.

[0029] FIG. 1 illustrates an outer spacer fabric layer 10 and an inner foam-fabric layer 20 according to an embodiment of the present application. As shown in FIG. 1, the outer spacer fabric layer 10 comprises at least two fabric layers 102 and fusible yarn 101. The inner foam-fabric layer 20 comprises a fabric layer for contact with a wearer's skin and a foam layer for molding together with the outer spacer fabric layer 10. The inner foam-fabric layer preferably comprises a fabric layer laminated with a foam layer. Fusible yarn is preferably disposed together with other fabric yarn within one of the at least two fabric layers 102, preferably the outermost fabric layer, to form a support within the fabric layer after molding. The spacer fabric layer 10 comprising fusible yarn may improve the support and breathability of the bra cup. The fusible yarn and other yarn are mixed and woven in the outer spacer fabric layer. When the outer spacer fabric layer comprising fusible yarn is molded under heat and pressure, the fusible yarn will be fused under high temperature. For instance, a temperature under which fusible yarn may fuse is not less than 150° C.

[0030] FIG. 2 illustrates a molded outer spacer fabric layer 10 according to an embodiment of the present application. As shown in FIG. 2, during the first molding process, the outer spacer fabric layer comprising fusible yarn is disposed between an upper male mold 301 and a lower female mold 302. The male and female molds are heated and then the upper male mold is lowered so that heat and pressure are applied to the outer spacer fabric layer to mold it to form a 3-D shape. After the molded spacer fabric layer is cooled, a 3-D cup shape is formed after the first molding process. After molding, the portion of spacer fabric that contains fusible yarn or that contains more fusible yarn will be more rigid than the portion of spacer fabric that does not contain fusible yarn or that contains fewer fusible yarn, and the more rigid portion will be less elastic and will provide improved and better support for the bra cup.

[0031] FIG. 3 illustrates a molded brassiere cup 50 according to an embodiment of the present application. As shown in FIG. 3, the cup 50 may comprise an inner foam-fabric layer 20, an inner foam layer 401, a non-stretchable fabric layer 402, a plastic underwire 403, an outer foam layer 404, and an outer spacer fabric layer 10. The inner foam layer 401, the non-stretchable fabric layer 402, the plastic underwire 403, and the outer foam layer 404 are placed in sequence between the inner foam-fabric layer 20 and the molded outer spacer fabric layer 10, and then the assembly is molded between the male and female molds under heat and pressure to form a 3-D cup shape after the second molding process.

[0032] The plastic underwire 403 may be disposed between the inner foam layer 401 and the outer foam layer 404, and thus may be sandwiched between the inner foam-fabric layer 20 and the outer spacer fabric layer 10 so as to provide a supporting function similar to that provided by a metal underwire while improving the comfort of the wearer. The sandwiched plastic underwire 403 may comprise various kind of thermoplastic material. For example, the plastic underwire 403 may comprise polypropylene (PP), nylon, thermoplastic rubber (TPR), polyurethane (PU), thermoplastic elastomer (TPE), thermoplastic polyester elastomer (TPEE), or the like.

[0033] FIG. 4 illustrates a molded brassiere cup 50′ according to another embodiment of the present application. The brassiere cup 50′ has a structure substantially similar to that of the cup 50 except for the shape of the inner foam-fabric layer. The inner foam-fabric layer may span the whole cup, as shown in FIGS. 3, 5 and 9, or may span only a portion, preferably the lower region, of the cup, as shown in FIGS. 4, 6 and 10. For example, in one embodiment of the present application, the inner foam-fabric layer 20 may span or cover the entire inner surface of the cup on the inner side of the cup 50, i.e. the side which is in contact with the wearer's body. In the cup 50′ as discussed in another embodiment of the present invention, the inner foam-fabric layer 20 may cover or span only a portion of the inner surface of the cup on the inner side of the cup 50′ which is in contact with the wearer's body.

[0034] Fusible yarn and other yarns may be mixed and woven into the spacer fabric layer in different proportions according to needs, so as to obtain an outer spacer fabric layer having different or varying fusible yarn contents. Generally, in the spacer fabric layer, a higher content of fusible yarn leads to better support and better protection for the wearer. For example, the content of fusible yarn in the cup may gradually increase from the upper region to the lower region of the cup, so that the lower region of the cup includes more fusible yarn to improve supporting performance. Because the upper region generally requires less supporting performance, and because the comfort of the wearer is preferred, the upper region of the cup may include relatively less fusible yarn so to provide better comfort. As illustrated in FIGS. 7 and 8, the content of fusible yarn increases from the upper region of the bra cups to the lower region of the bra cups. In FIGS. 7 and 8 which illustrate an embodiment, in each bra cup as illustrated, there are three regions, each region corresponding to a different content of fusible yarn, and the content of fusible yarn increases from the upper region to the middle region and then to the lower region.

[0035] Because the proportion of fusible yarn in the spacer fabric layer may be changed as required, the spacer fabric layer may be adapted to sports bra having different supporting requirements. For example, in high-impact exercises, the sports bra needs to provide higher supporting performance, so the content of fusible yarn in the outer spacer fabric layer is relatively higher; for example, the content of fusible yarn is about 70% to 100%. In moderate-impact exercises, the content of fusible yarn in the outer spacer is fabric layer is, for example, about 40% to 70%. In low-impact exercises, the content of fusible yarn in the outer spacer fabric layer is, for example, about 10% to 40%.

[0036] As shown in FIGS. 5 and 6, after the second molding process, the molded cup is trimmed along a mold line to obtain the final shape of the bra cup. The cups shown in FIGS. 5 and 6 are substantially the same except for the difference between the coverage areas of the inner foam-fabric layers on the inner surface of the cup covered by the inner foam-fabric layer. FIG. 7 illustrates a front schematic view of the brassiere cup containing fusible yarn after molding and trimming.

[0037] FIG. 8 illustrates a schematic view of the front side of the bra comprising the cup according to the embodiments of the present invention, and FIGS. 9 and 10 illustrate schematic views of the back side of the bra comprising the cup according to the embodiments of the present invention. After trimming the cup, side wings may be attached. The side wing may be designed as a single piece to attach to the cups to form a pullover bra. The side wing may also be designed as two pieces attached to the sides of the left and right cup respectively. Shoulder straps may also be added, for example by attaching the straps to the upper part of the cups and the upper part of the side wings.

[0038] Those skilled in the art should understand that the above exemplary embodiments are merely examples provided for the purpose of illustration and are not intended to limit the scope of the invention. Any modification, equivalent replacement, or the like, made within the teaching of this application and the protection scope of the claims shall fall within the protection scope of this application.
