DETAILED DESCRIPTION

[0028] The utility model concepts of the present disclosure will be described below using terms generally employed by those skilled in the art to convey the substance of their work to other skilled artisans in the art. However, these utility model concepts can be embodied in many different forms, and thus should not be considered limited to the embodiments described herein.

[0029] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0030] The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0031] In order to solve the problem that the support in the prior art is difficult to balance the body, comfort, strength and support, the present embodiment proposes a three-dimensional support with a multi-layer non-metal structure, as shown in the accompanying drawings. Figures 1-6 The three-dimensional support 1 comprises an outer fabric 2 and a transition isolation layer fabric 3 arranged in sequence from the outside to the inside, the outer fabric 2 is wrapped outside the entire transition isolation layer fabric 3, a closed loop cavity 6 is arranged inside the transition isolation layer fabric 3, and at least one intermediate fabric layer 5 is arranged inside the closed loop cavity 6; the closed loop cavity 6 is filled with a hot melt medium 4, and the hot melt medium 4 can penetrate into the intermediate fabric layer 5 and the transition isolation layer fabric 3 respectively.

[0032] Therefore, by arranging the multi-layer non-metal fabric structure from the outside to the inside, and filling the closed loop cavity 6 with the hot melt medium 4 while penetrating the hot melt medium 4 into the intermediate fabric layer 5 and the transition isolation layer fabric 3 respectively, the three-dimensional support 1 has good elasticity and certain deformation ability during normal temperature use, so that the bra using the three-dimensional support 1 has good body and comfort, on the other hand, the hot melt medium 4 penetrates into the intermediate fabric layer 5 and the transition isolation layer fabric 3, and the flowability of the hot melt medium 4 decreases under normal temperature environment (or cooling), so that the hot melt medium 4, the intermediate fabric layer 5 and the transition isolation layer fabric 3 are solidified as a whole (referred to as "core body"), the positions of each intermediate fabric layer 5 in the core body are relatively fixed and unchanged, and accordingly, compared with the conventional multi-layer simple "stacking type" structure, the three-dimensional support with this structure has greater strength and elasticity, and can provide better strength and support.

[0033] It should be noted that the process of hot melt medium 4 penetrating into the intermediate fabric layer 5, the transition isolation layer fabric 3 is in the process of producing the three-dimensional support 1 in the high temperature hot melt processing, and then the three are integrated into a core under normal temperature or cooling, and then the three-dimensional support 1 is processed into a specific shape according to the shape of the designed tool or mold. Preferably, the shape and cross-sectional shape of the three-dimensional support 1 are achieved by hot pressing and cooling by the mold or tool used. The structure of the three-dimensional support 1 before hot pressing is processed by sewing, bonding and other processes of each layer of fabric, intermediate filler, etc. At the same time, the fabric has small fabric holes or gaps, and the hot melt medium 4 in the hot melt state can penetrate into the fabric.

[0034] For the penetration of the hot melt medium 4 in the transition isolation layer fabric 3, in the high temperature environment, the hot melt medium 4 in the hot melt state enters the transition isolation layer fabric 3 under pressure, but at the same time, it is subjected to the reverse force of the transition isolation layer fabric 3, only a small amount of hot melt medium 4 can penetrate into the transition isolation layer fabric 3.

[0035] Correspondingly, for any wall surface of the transition isolation layer fabric 3, the depth of the hot melt medium 4 penetrating into the transition isolation layer fabric 3 is < the wall thickness of the transition isolation layer fabric 3. That is, the hot melt medium 4 in this application can only penetrate into the transition isolation layer fabric 3 and terminate in the transition isolation layer fabric 3, and will not completely penetrate and pass through the transition isolation layer fabric 3, and will not contact the outer fabric 2 at all, so that the outer fabric 2 will not change in appearance or texture, and the appearance and touch quality of the entire three-dimensional support 1 can be guaranteed. Correspondingly, for the part of the hot melt medium 4 penetrating into the transition isolation layer fabric 3, in order to facilitate understanding, this application defines it as the penetrating medium 31.

[0036] The outer fabric 2 and the transition isolation layer fabric 3 have a gap 7, so that the outer fabric 2 and the transition isolation layer fabric 3 can be relatively displaced; preferably, the distance between the inner wall surface of the outer fabric 2 and the outer wall surface of the transition isolation layer fabric 3 is 0.1-1mm, which can also be understood as the thickness of the gap 7 is 0.1-1mm, so that the outer fabric 2 and the transition isolation layer fabric 3 have a certain relative displacement space, and when subjected to different external forces, they can be directly contacted, adhered and separated, which can effectively meet the use effect under different curves and different stress conditions, and help to widen the application range of the three-dimensional support 1.

[0037] Alternatively, an adhesive medium (not shown) is arranged between the outer fabric 2 and the transition isolation layer fabric 3, and the outer fabric 2 and the transition isolation layer fabric 3 are connected through the adhesive medium, so that they are relatively fixed and will not relatively displace after being stressed, which can better guarantee the tightness between the components of the three-dimensional support 1 and the overall flatness and hand quality of the three-dimensional support 1.

[0038] In order to facilitate the filling and infiltration of the hot melt medium 4 in the closed loop cavity 6, the intermediate fabric layer 5 is a sheet structure with a plurality of through holes, and the arrangement density of the through holes is 400-1200 meshes, so that the hot melt medium 4 after being heated and melted can not only infiltrate into the inside of the intermediate fabric layer 5, but also relatively freely flow in the closed loop cavity 6 through the through holes, which on the one hand facilitates the hot pressing and setting, and on the other hand enables the hot melt medium 4 to be more uniformly distributed in the entire closed loop cavity 6, which helps to guarantee the homogenization of the entire core and the three-dimensional support 1 in the elastic performance and strength performance.

[0039] Preferably, 1-10 layers of the intermediate fabric layer 5 are arranged in the closed loop cavity 6, and the intermediate fabric layer 5 and the inner wall of the transition isolation layer fabric 3 have a filling space, and / or any two adjacent intermediate fabric layers 5 have a filling space. Thus, it is ensured that the intermediate fabric layer 5 and the transition isolation layer fabric 3 and the two intermediate fabric layers 5 can be filled with the hot melt medium 4, and the uniformity of the distribution of the hot melt medium 4 in the entire closed loop cavity 6 is ensured, so as to guarantee the excellent quality indicators such as the elasticity and strength of the entire core.

[0040] 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, so as to not only effectively ensure the strength of each fabric itself, but also facilitate the reduction of the weight and the space occupied as much as possible, so that the three-dimensional support 1 can provide bra support and improve the user's body comfort as much as possible.

[0041] As for the material of each fabric, existing fabric materials such as chemical fibers, cotton, hemp, silk, etc. can be directly used, and the present application does not make too many limitations. As for the hot melt medium 4, it is a non-metallic material with fluidity after being heated and melted, and preferably, the hot melt medium 4 is an organic high polymer compound with a melting temperature greater than 100℃, including but not limited to PETG, PE, PP, PCL, PVA, TPU, etc., so as to facilitate hot pressing and setting, and at the same time, in combination with the related technical solutions of the three-dimensional support 1, a core meeting the strength and elasticity requirements can also be formed, which meets the quality requirements of bra products.

[0042] The overall shape of the three-dimensional support component 1 is the same as the human body shape corresponding to its position on the bra, as shown in the attached figure. Figures 1-3 As shown, the three-dimensional support 1 includes a first arc segment region 11, a second arc segment region 12, and a third arc segment region 13 connected in sequence. For ease of understanding, the end of the first arc segment region 11 furthest from the second arc segment region 12 is designated as end E, the end of the third arc segment region 13 furthest from the second arc segment region 12 is designated as end F, the virtual boundary line between the first arc segment region 11 and the second arc segment region 12 is designated as line M, and the virtual boundary line between the second arc segment region 12 and the third arc segment region 13 is designated as line N. The first arc segment region 11... The second arc segment 12 and the third arc segment 13 are both curved surfaces. The first arc segment 11 is twisted counterclockwise along the direction from line M to end E, with a twist angle of 35°-60°. The second arc segment 12 is twisted counterclockwise along the direction from line N to end F, with a twist angle of 35°-60°. This allows the three-dimensional support component 1 used in 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 explanation and do not represent the three-dimensional support component 1 as three independent segments.

[0043] The three-dimensional support 1 has a quadrilateral normal section at any point along its arc, 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.

[0044] For the arc-shaped 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 shape of the human body, which helps to optimize the stress distribution on the three-dimensional support 1 and improve its strength and overall supporting force.

[0045] Based on this, refer to the appendix Figure 6The width of the normal section is denoted as W, and the thickness of the normal section is denoted as h, 5mm≤W≤12mm, and 0.6mm≤h≤2mm. Thus, while meeting the size design requirements of each fabric layer and the closed loop cavity 6, the hot melt medium 4 that meets the filling amount design requirements can also be filled, so that the entire three-dimensional support 1 can meet various application requirements such as lightness, elasticity, strength, support, and the like, and also helps to further optimize the stress distribution on the entire three-dimensional support 1, and provides better strength and support.

[0046] In the utility model, for any bra, can include the three-dimensional support 1 described in the embodiment, and on the basis of the related technical solutions provided in the embodiment, the bra also includes conventional components such as the structure of the cup, and in view of these conventional components are prior art, here do not make superfluous repetition. Meanwhile, the setting and assembly of the three-dimensional support 1 of the present application in the bra can also use the prior art, and no further description is made.

[0047] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
