Bra structure

Abstract

A bra structure comprises two cups connected to each other. Each cup has an apex area and a peripheral area. A wing extends from the edge of each peripheral area. The ends of two wings, which are far away from the cups, can be fastened together. A single piece of a seamless 3D fabric substrate, such as a spacer fabric or a sandwich fabric, is compression-molded to integrally form two cups and two wings. After compression-molding, the 3D fabric substrate has a greater thickness in the apex area than in the peripheral area. The bra structure is seamless, air-permeable, thin, lightweight, pressure-free, and comfortable. Further, the bra structure is fast to fabricate and low in fabrication cost.

What is claimed is: 
     
         1 . A bra structure comprising
 two cups connected to each other, each having a apex area and a peripheral area, wherein two wings are respectively extended from said peripheral areas of said two cups, and wherein ends of said wings, which are far away from said cups, can be fastened together, and wherein said two cups connected to each other and said two wings extended from said cups are integrally formed via compression-molding a single piece of a seamless 3D fabric substrate, and wherein after compression-molding, said 3D fabric substrate has a larger thickness in said apex areas than in said peripheral areas and said wings.   
     
     
         2 . The bra structure according to  claim 1 , wherein after compression-molding, said 3D fabric substrate is gradually thinned from said apex areas to said peripheral areas. 
     
     
         3 . The bra structure according to  claim 1 , wherein after compression-molding, a thickness of said 3D fabric substrate in said peripheral area is equal to or smaller than a thickness of said 3D fabric substrate in said wing. 
     
     
         4 . The bra structure according to  claim 1 , wherein after compression-molding, said 3D fabric substrate in said wing is gradually thinned from one end of said wing, which is near said cup, to another end of said wing, which is far away from said cup. 
     
     
         5 . The bra structure according to  claim 1 , wherein said apex area is at a center of said cup and occupies 30-50% area of said cup. 
     
     
         6 . The bra structure according to  claim 1 , wherein said 3D fabric substrate is 2 mm-10 mm thick in said apex area, and wherein said 3D fabric substrate is 0.1 mm-5 mm thick in said peripheral area and said wing. 
     
     
         7 . The bra structure according to  claim 1 , wherein said two cups are connected by a central member, and wherein said two cups, said central member and said two wings are integrally fabricated via compression-molding a single piece of said seamless 3D fabric substrate. 
     
     
         8 . The bra structure according to  claim 1 , wherein said 3D fabric substrate is a sandwich fabric or a spacer fabric. 
     
     
         9 . The bra structure according to  claim 1 , wherein said 3D fabric substrate includes an upper fabric layer, a lower fabric layer, and a middle fabric layer between said upper fabric layer and said lower fabric layer, and wherein said middle fabric layer is formed by several pieces of waved yarn, and wherein crests of said waved yarn are connected with said upper fabric layer, and wherein troughs of said waved yarn are connected with said lower fabric layer. 
     
     
         10 . The bra structure according to  claim 9 , wherein said waved yarn of said middle fabric layer is formed by monofilaments. 
     
     
         11 . The bra structure according to  claim 9 , wherein said upper fabric layer and/or said lower fabric layer is knitted with shrinkable core-spun yarn. 
     
     
         12 . The bra structure according to  claim 9 , wherein said upper fabric layer and/or said lower fabric layer is knitted with polyester yarn, elastic yarn, nylon yarn, cotton yarn, rayon yarn, or a combination thereof. 
     
     
         13 . The bra structure according to  claim 1  further comprising an outer covering layer stuck to an outer surface of said 3D fabric substrate, wherein said 3D fabric substrate and said outer covering layer are jointly compression-molded to integrally form said two cups connected to each other and said two wings extended from said cups. 
     
     
         14 . The bra structure according to  claim 13 , wherein said outer covering layer is a knitted fabric, a woven fabric, a woolen fabric, a nylon fabric, a rayon fabric, a polyester fabric, or a cotton fabric. 
     
     
         15 . The bra structure according to  claim 1 , wherein jacquard, embossing, printing or a combination thereof is formed on at least one surface of said 3D fabric substrate. 
     
     
         16 . The bra structure according to  claim 1 , wherein bordering elements are sewed on a portion of edges of said cups and said wings, and wherein steel wires are disposed in lower edges of inner sides of said cups. 
     
     
         17 . The bra structure according to  claim 1  further comprising two shoulder straps, wherein one end of each said shoulder strap is connected with an upper edge of said cup, and wherein another end of said shoulder strap is connected with an upper edge of said wing connected with said cup. 
     
     
         18 . The bra structure according to  claim 1 , wherein ends of said two wings, which are far away from said cups, are fastened together with a hook and eye fastening mechanism, a hook and loop fastening mechanism, or an elastic ribbon.
