Description

This utility model relates to the field of clothing technology, and particularly to a multi-layered non-metallic three-dimensional support component and bra. Background Art: Existing bras often incorporate support components, which are typically made of different hard metal materials such as steel rings or soft flat support components, fixed in designated positions on the bra to fix and shape it. However, current support components on the market often have several problems. For example, bras using hard steel rings as support components often have poor body conformity and exert pressure on the body; bras using soft flat support components are prone to deformation under stress, resulting in a loss of the bra's fixing and shaping function. Therefore, there is an urgent need for a support component that can balance conformity, comfort, strength, and support. Utility Model Content: In view of this, this utility model aims to propose a multi-layered non-metallic three-dimensional support component and bra to solve the problem that existing support components cannot simultaneously achieve conformity, comfort, strength, and support. To achieve the above objectives, the technical solution of this utility model is as follows: A multi-layered non-metallic three-dimensional support includes an outer fabric and a transition isolation layer fabric arranged sequentially from the outside to the inside. The outer fabric wraps around the entire transition isolation layer fabric. A closed-loop cavity is provided inside the transition isolation layer fabric, and at least one intermediate fabric layer is provided within the closed-loop cavity. The closed-loop cavity is filled with a thermoplastic medium, and the thermoplastic medium can penetrate into the intermediate fabric layer and the transition isolation layer fabric respectively. Further, for any wall surface of the transition isolation layer fabric, the depth of penetration of the thermoplastic medium into the transition isolation layer fabric is less than the wall thickness of the transition isolation layer fabric. Further, there is a gap between the outer fabric and the transition isolation layer fabric, allowing relative displacement between them, enabling them to contact or separate. Furthermore, an adhesive medium is disposed between the outer fabric and the transition isolation layer fabric, and the outer fabric and the transition isolation layer fabric are connected by the adhesive medium. Furthermore, the intermediate fabric layer is a sheet-like structure with multiple through holes, the density of which is 400-1200 mesh. Furthermore, 1-10 intermediate fabric layers are disposed in the closed-loop cavity, and there is a filling space between the intermediate fabric layers and the inner wall of the transition isolation layer fabric, and / or a filling space between any two adjacent intermediate fabric layers.Furthermore, the three-dimensional support member includes a first arc segment area, a second arc segment area, and a third arc segment area connected sequentially. The end of the first arc segment area furthest from the second arc segment area is designated as end E, and the end of the third arc segment area furthest from the second arc segment area is designated as end F. The virtual boundary line between the first and second arc segment areas is designated as line M, and the virtual boundary line between the second and third arc segment areas is designated as line N. The first arc segment area is twisted counterclockwise along the direction from line M to end E, with a twist angle of 35°-60°. The second arc segment area is twisted counterclockwise along the direction from line N to end F, with a twist angle of 35°-60°. Furthermore, any normal section of the arc shape of the three-dimensional support member is a quadrilateral, and any two adjacent sides are connected by a rounded corner transition. Furthermore, the cross-sectional area of ​​the normal section with the largest cross-sectional area is denoted as X, and the cross-sectional area of ​​the normal section with the smallest cross-sectional area is denoted as Y, (XY) / Y::::;0.6; The width of the normal section is denoted as w, and the thickness of the normal section is denoted as h, 5mm ::::;w::::; 12mm, 0.6mm::::;h::::;2mm. A bra includes the aforementioned multi-layered non-metallic three-dimensional support member. Compared to existing technologies, the multi-layered non-metallic three-dimensional support and bra described in this utility model has the following advantages: The multi-layered non-metallic three-dimensional support and bra of this utility model, through the arrangement of multiple layers of non-metallic fabric from the outside to the inside, and while filling the closed-loop cavity with a heat-melting medium, also allows the heat-melting medium to permeate into the intermediate fabric layer and the transition isolation layer, so that the three-dimensional support has good elasticity and a certain degree of deformation capability during use at room temperature. This results in better body conformability and comfort for bras using the three-dimensional support. Furthermore, the heat-melting medium permeates into the intermediate fabric layer and the transition isolation layer, and its fluidity diminishes at room temperature (or after cooling), allowing the heat-melting medium, intermediate fabric layer, and transition isolation layer to achieve optimal performance. The transition isolation layer fabric is solidified into a single unit (referred to as the "core"). The positions of the various intermediate fabric layers within the core are also relatively fixed. Correspondingly, compared to the conventional multi-layered simple "stacked" structure, the three-dimensional support component with this structure has greater strength and elasticity, providing better strength and support.

Detailed Description of the Embodiments The present invention will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be considered as limiting the embodiments described herein. It should be noted that, without conflict, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. To address the problem that existing support components struggle to balance conformity, comfort, strength, and support force, this embodiment proposes a multi-layered non-metallic three-dimensional support component, as shown in Figures 1-8. The three-dimensional support component 1 includes an outer fabric layer 2 and a transition isolation layer fabric 3 arranged sequentially from the outside to the inside. The outer fabric layer 2 wraps around the entire transition isolation layer fabric 3. A closed-loop cavity 6 is provided inside the transition isolation layer fabric 3, and at least one intermediate fabric layer 5 is provided within the closed-loop cavity 6. The closed-loop cavity 6 is filled with a thermoplastic medium 4, which can penetrate both the intermediate fabric layer 5 and the transition isolation layer fabric 3.Therefore, this invention employs a multi-layered non-metallic fabric structure from the outside in. While the closed-loop cavity 6 is filled with a hot-melt medium 4, the hot-melt medium 4 is also infiltrated into the intermediate fabric layer 5 and the transition isolation layer fabric 3. This allows the three-dimensional support component 1 to exhibit good elasticity and a certain degree of deformation capability during normal temperature use, resulting in better body conformability and comfort for bras using the three-dimensional support component 1. Furthermore, the hot-melt medium 4 infiltrates into the intermediate fabric layer 5 and the transition isolation layer fabric 3, and under normal temperature (or cooling) conditions, the fluidity of the hot-melt medium 4 diminishes, causing the hot-melt medium 4, intermediate fabric layer 5, and transition isolation layer fabric 3 to solidify into a single unit (referred to as the "core"). The positions of the intermediate fabric layers 5 within the core also remain relatively fixed. Consequently, compared to conventional multi-layered simple "stacked" structures, this three-dimensional support component exhibits greater strength and elasticity, providing better strength and support. It should be noted that the process of the hot-melt medium 4 penetrating into the intermediate fabric layer 5 and the transition isolation layer fabric 3 is a high-temperature hot-melt processing process during the production of the three-dimensional support 1. Subsequently, at room temperature or under cooling, the three components form an integrated core. Then, the three-dimensional support 1 is processed into a specific shape according to the designed tools or molds. Preferably, the shape and cross-sectional shape of the three-dimensional support 1 are achieved by hot pressing and cooling using the molds or tools used. The structural processing of the three-dimensional support 1 before hot pressing is achieved by sewing, bonding, and other processes for each layer of fabric and the intermediate filling material. At the same time, the fabric has small pores or gaps, allowing the hot-melt medium 4 in the hot-melt state to penetrate into the fabric. Regarding the penetration of the hot-melt medium 4 into the transition isolation layer fabric 3, in a high-temperature environment, the hot-melt medium 4 in the hot-melt state enters the transition isolation layer fabric 3 under pressure, but is simultaneously subjected to the reverse force of the transition isolation layer fabric 3, so only a small amount of the hot-melt medium 4 will penetrate into the transition isolation layer fabric 3. Correspondingly, for any wall surface of the transition isolation layer fabric 3, the depth to which the hot-melt medium 4 penetrates the transition isolation layer fabric 3 is less than the wall thickness of the transition isolation layer fabric 3. That is, in this application, the hot-melt medium 4 can only penetrate into the transition isolation layer fabric 3 and terminate within it. It will not completely penetrate and pass through the transition isolation layer fabric 3, nor will it have any contact with the outer fabric 2. This ensures that the outer fabric 2 will not undergo any changes in appearance or texture, thus guaranteeing the aesthetic appearance and tactile quality of the entire three-dimensional support 1.Correspondingly, for ease of understanding, this portion of the heat-fusible medium 4 that penetrates the transition isolation layer fabric 3 is defined as the penetration medium 31. A gap 7 exists between the outer fabric 2 and the transition isolation layer fabric 3, allowing relative displacement between them. Preferably, the distance between the inner wall of the outer fabric 2 and the outer wall of the transition isolation layer fabric 3 is 0.1-1 mm, which can also be understood as the thickness of the gap 7 being 0.1-1 mm. This allows for a certain relative displacement space between the outer fabric 2 and the transition isolation layer fabric 3. Under different external forces, they can directly contact and adhere, or separate from each other, effectively meeting the usage requirements under different conditions and stresses, thus helping to broaden the applicability of the three-dimensional support 1. Alternatively, an adhesive medium (not shown) may be provided between the outer fabric 2 and the transition isolation layer fabric 3, and the outer fabric 2 and the transition isolation layer fabric 3 may be connected by the adhesive medium, so that the two are relatively fixed and will not be displaced under force. This can better ensure the tightness of the connection between the components of the three-dimensional support 1, and ensure the overall flatness of the appearance and the quality of the feel of the three-dimensional support 1. To facilitate the filling and penetration of the thermoplastic medium 4 into the closed-loop cavity 6, the intermediate fabric layer 5 is a sheet structure with multiple through holes. The density of the through holes is 400-1200 mesh. Thus, the thermoplastic medium 4, after being heated and melted, can not only penetrate into the interior of the intermediate fabric layer 5, but also flow relatively freely within the closed-loop cavity 6 through the through holes. This facilitates hot pressing and shaping, preventing local obstruction or damage to the thermoplastic medium 4 due to its inability to flow freely during the pressing process. Furthermore, it allows the thermoplastic medium 4 to be more evenly distributed throughout the closed-loop cavity 6, helping to ensure the homogeneity of the elastic and strength properties of the entire core and the entire three-dimensional support 1. Preferably, the closed-loop cavity 6 contains 1-10 intermediate fabric layers 5. There is a filling space between the intermediate fabric layer 5 and the inner wall of the transition isolation layer fabric 3, and / or between any two adjacent intermediate fabric layers 5. This ensures that the space between the intermediate fabric layer 5 and the transition isolation layer fabric 3, and between any two intermediate fabric layers 5, can be filled with the hot-melt medium 4, ensuring the uniform distribution of the hot-melt medium 4 throughout the closed-loop cavity 6, thereby guaranteeing excellent quality indicators such as elasticity and strength of the entire core.The thickness of the intermediate fabric layer 5 is 0.1-0.5 mm, the wall thickness of the transition isolation layer fabric 3 is 0.1-1 mm, and the wall thickness of the outer fabric 2 is 0.2-1 mm. This not only effectively ensures the strength of each fabric but also helps to minimize its weight and space occupation, allowing the three-dimensional support component 1 to provide bra support while maximizing user comfort. Regarding the materials of each fabric, existing fabric materials such as chemical fibers, cotton, linen, and silk can be directly used; this application does not impose excessive restrictions. The hot-melt medium 4 is a non-metallic material that is fluid after being heated and melted. Preferably, the hot-melt medium 4 is an organic polymer compound with a melting point greater than 100°C, including but not limited to PETG, PE, PP, PCL, PVA, TPU, etc., which facilitates hot pressing and shaping. At the same time, combined with the relevant technical solutions of the three-dimensional support component 1, it can also form a core that meets the requirements of strength and elasticity, thus satisfying the quality requirements of bra products. Regarding the overall shape of the three-dimensional support component 1, it corresponds to the shape of the human body at its position on the bra. Specifically, as shown in Figures 1-3, the three-dimensional support component 1 includes a first arc segment area 11, a second arc segment area 12, and a third arc segment area 13 connected in sequence. For ease of understanding, the end of the first arc segment area 11 away from the second arc segment area 12 is designated as end E, and the end of the third arc segment area 13 away from the second arc segment area 12 is designated as end F. The virtual dividing line between the first arc segment area 11 and the second arc segment area 12 is designated as line M, and the virtual dividing line between the second arc segment area 12 and the third arc segment area 13 is designated as line N. The first arc segment area 11, the second arc segment area 12, and the third arc segment area 13 are all curved surfaces. The first arc segment area 11 is twisted counterclockwise along the direction from line M to end E, and the twist angle of the first arc segment area 11 is 35°-60°. The second arc segment area 12... The second arc segment 12 is twisted counterclockwise from line N to end F, with a twist angle of 35°-60°. This allows the three-dimensional support component 1 of the bra to better conform to the shape of the human body, improving the bra's fit and comfort. It should be noted that the first arc segment 11, the second arc segment 12, and the third arc segment 13 are merely regional divisions for ease of description and do not represent the three-dimensional support component 1 as three independent segments. Any normal section of the arc of the three-dimensional support component 1 is a quadrilateral, preferably a regular quadrilateral such as a rectangle or rhombus, with any two adjacent sides connected by a rounded corner transition.Of course, the two sides can also be connected according to the product design shape. For the arc extension of the three-dimensional support 1, depending on the position of the normal cross-section, the three-dimensional support 1 undoubtedly has multiple normal cross-sections. The cross-sectional areas of all normal cross-sections can be all the same, all different, or partially the same and partially different. Preferably, for all normal cross-sections, the cross-sectional area of ​​the normal cross-section with the largest cross-sectional area is denoted as X, and the cross-sectional area of ​​the normal cross-section with the smallest cross-sectional area is denoted as Y, where (XY) / Y ~ 0.6. This allows the three-dimensional support 1 to have appropriate cross-sectional dimensions while better conforming to the human body shape, which helps optimize the force distribution on the three-dimensional support 1 and improves its strength and overall support force. Based on this, referring to Figure 6, the width of the normal cross-section is denoted as w, and the thickness of the normal cross-section is denoted as h, where 5mm ~ W ~ 12mm, and 0.6mm ~ h ~ 2mm. This allows the three-dimensional support component 1 to meet the dimensional design requirements of each fabric layer and the closed-loop cavity 6, while also filling with a hot-melt medium 4 that meets the filling amount design requirements. This enables the entire three-dimensional support component 1 to simultaneously meet various application needs such as lightness, elasticity, strength, and support. It also helps to further optimize the stress distribution on the entire three-dimensional support component 1, providing better strength and support. In this utility model, any bra can include the three-dimensional support component 1 described in this embodiment. Based on the relevant technical solutions provided in this embodiment, the bra also includes conventional components such as cups. Since these conventional components are all existing technologies, they will not be described in detail here. Furthermore, the setting and assembly of the three-dimensional support component 1 in the bra can also adopt existing technologies, which will not be described in detail here. The above description is only a typical embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. 8 HK 30138781 A Claim 1.
