Description

Cup with elastic support, bra, garment and cup manufacturing method Technical Field The invention relates to the field of underwear and functional clothing, in particular to a cup with elastic support, a bra, clothing and a cup manufacturing method. Background Conventional bra cups are typically made from multiple layers of fabric (e.g., cotton, chemical cloth) and filled cotton (e.g., sponge) by a heated molding process. In the process, the cup blank is placed in a high-temperature mold, and the fiber or polymer chain of the cup blank deforms and memorizes a new 3D curved surface shape under the action of heat and pressure, so that the 3D three-dimensional modeling of the cup is realized. A limitation of this method is that the cloth and cotton that make up the cup body essentially lack excellent, durable elastic recovery stress. Once set, its shape and supporting force are largely static. In order to improve comfort during activities, there are bras made of elastic fabrics (such as lycra) on the market. However, such bras often sacrifice structural support of the cup itself in pursuit of the overall elasticity of the shell, resulting in inadequate support, especially when supporting a large breast or performing high intensity exercises. On the other hand, a brassiere having a rigid support structure such as a steel ring is generally used, but the brassiere has high structural rigidity and cannot be adaptively adjusted according to physical activities and postures, although static support can be provided. This not only tends to create a feeling of compression and discomfort and tightening during activity, but also affects comfort over long periods of wear, and lacks effective force cushioning and redistribution during dynamic processes. The present invention has been made in view of the above-mentioned problems. Disclosure of Invention The invention aims to provide a cup with elastic support, a bra, clothing and a cup manufacturing method, which are used for solving at least one technical problem. The core of the invention is to provide a cup with elastic support, which comprises a cup body and an elastic support body made of heat-resistant elastic polymer, wherein the elastic support body is pre-attached on a cup blank, is stretched and deformed together with a material layer in the heating and molding process of the cup body, and keeps the stretching state of elastic strain due to the constraint of the material after the material layer is shaped, so that the corresponding part of the cup body obtains continuous elastic strain or trend of elastic strain. The invention solves the problems of empty cup and breast displacement dislocation caused by lack of dynamic resilience force of the traditional cup, poor comfort level, inaccurate shaping and the like caused by uneven static distribution of supporting force. In order to solve the technical problems, the invention provides a cup with elastic support, which comprises a cup body and an elastic support body, wherein the elastic support body is made of a heat-resistant elastic polymer with memory deformation resistance, and is elastically attached to corresponding parts of the cup body in a deformation manner, so that the corresponding parts of the cup body keep elastic strain or elastic strain trend to provide a supporting effect for breast tissues of a wearer in real time. The bra cup with the elastic support is made of polyurethane, and at least a partial area of the elastic support is stretched and deformed along the convex curved surface of the corresponding part of the bra cup body with the 3D structure by heating and mould pressing. According to the bra cup with the elastic support, the elastic support body is in the hollow structure, and the hollow structure is formed by interweaving at least two groups of lines in different directions to form a reticulate pattern. The bra cup with the elastic support is characterized in that the bra cup body is provided with a bra cup part for accommodating breasts, and the elastic support body is arranged at the lower cup part in the bra cup part and is used for supporting and supporting the breasts upwards and inwards. According to the cup with the elastic support, the degree of the reticulate line density of the elastic support body is gradually reduced from the bottom of the lower cup part to the top direction, so that the supporting and bearing effect of the lower cup part gradually reduces from the bottom to the top. The cup with the elastic support comprises at least two elastic areas arranged at different parts of the cup body. The bra cup with the elastic support comprises a first elastic region, which is covered on the lower cup part of the bra cup part and is used for supporting and bearing the breast, and a second elastic region, which is positioned on the side ratio part and is used for shaping. The bra cup with the elastic support comprises a first elastic region, which is covered on the lower cup part
