Description

Technical Field

[0001] The invention relates to the technical field of clothing, and in particular to a multi-layered non-metallic three-dimensional supporting piece and a bra. Background Art

[0002] Existing bras are often provided with support members, and accordingly, the support members are usually fixed at set positions of the bra products using different hard metal steel rings or soft flat support members to fix and shape the bra products.

[0003] However, the current support parts on the market often have many problems. For example, bras that use hard steel rings as support parts often have poor body-adaptability and exert pressure on the human body; bras that use soft flat support parts are more likely to be deformed by force, resulting in the loss of the bra's fixing and shaping function.

[0004] For this reason, there is an urgent need on the market for a support component that can take into account portability, comfort, strength, and support. Summary of the invention

[0005] In view of this, the present invention aims to provide a multi-layered non-metallic three-dimensional support member and bra to solve the problem that the support members in the prior art are difficult to balance body-fitting performance, comfort, strength and support force.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A multi-layer non-metallic three-dimensional support component comprises an outer fabric layer and a transition isolation layer fabric which are arranged in sequence from the outside to the inside, wherein the outer fabric layer is wrapped around the outside of the entire transition isolation layer fabric, a closed-loop cavity is arranged inside the transition isolation layer fabric, and at least one intermediate fabric layer is arranged inside the closed-loop cavity; a hot-melt medium is filled in the closed-loop cavity, and the hot-melt medium can penetrate into the intermediate fabric layer and the transition isolation layer fabric respectively.

[0008] Furthermore, for any wall surface of the transition isolation layer fabric, the depth of penetration of the hot-melt medium into the transition isolation layer fabric is less than the wall thickness of the transition isolation layer fabric.

[0009] Furthermore, there is a gap between the outer fabric and the transition isolation layer fabric, and the outer fabric and the transition isolation layer fabric can be relatively displaced, so that the outer fabric and the transition isolation layer fabric can be in contact with or separated from each other.

[0010] Furthermore, a viscose medium is provided between the outer fabric and the transition isolation layer fabric, and the outer fabric and the transition isolation layer fabric are connected via the viscose medium.

[0011] Furthermore, the middle fabric layer is a sheet structure having a plurality of through holes, and the through holes are arranged at a density of 400-1200 meshes.

[0012] Furthermore, 1 to 10 intermediate fabric layers are arranged in the closed-loop cavity, and a filling space is provided between the intermediate fabric layer and the fabric inner wall of the transition isolation layer, and / or a filling space is provided between any two adjacent intermediate fabric layers.

[0013] Furthermore, the three-dimensional support member includes a first arc segment area, a second arc segment area, and a third arc segment area connected in sequence; the end of the first arc segment area away from the second arc segment area is recorded as the E end, the end of the third arc segment area away from the second arc segment area is recorded as the F end, the virtual boundary line between the first arc segment area and the second arc segment area is recorded as the M line, and the virtual boundary line between the second arc segment area and the third arc segment area is recorded as the N line, the first arc segment area is twisted counterclockwise along the direction from the M line to the E end, and the twisting angle of the first arc segment area is 35°-60°, the second arc segment area is twisted counterclockwise along the direction from the N line to the F end, and the twisting angle of the second arc segment area is 35°-60°.

[0014] Furthermore, any normal cross section of the arc of the three-dimensional support member is a quadrilateral, and any two adjacent sides are connected in a rounded transition manner.

[0015] Furthermore, the cross-sectional area of ​​the normal cross section with the largest cross-sectional area is recorded as X, and the cross-sectional area of ​​the normal cross section with the smallest cross-sectional area is recorded as Y, (XY) / Y≤0.6; the width of the normal cross section is recorded as W, and the thickness of the normal cross section is recorded as h, 5mm≤W≤12mm, 0.6mm≤h≤2mm.

[0016] A bra comprises the above-mentioned multi-layered non-metallic three-dimensional supporting piece.

[0017] Compared with the prior art, the multi-layered non-metallic three-dimensional support member and bra of the present invention have the following advantages:

[0018] The present invention discloses a multi-layer non-metallic three-dimensional support member and bra, which are constructed by arranging a multi-layer non-metallic fabric structure from the outside to the inside, and filling a closed-loop cavity with a hot-melt medium while infiltrating the hot-melt medium into the middle fabric layer and the transition isolation layer fabric, respectively. This allows the three-dimensional support member to have good elasticity and a certain degree of deformation ability during use at room temperature, so that the bra using the three-dimensional support member has good body-fitting and comfort. On the other hand, the hot-melt medium infiltrates the middle fabric layer and the transition isolation layer fabric, and the fluidity of the hot-melt medium disappears under room temperature (or cooling), so that the hot-melt medium, the middle fabric layer, and the transition isolation layer fabric are solidified into one (referred to as the "core body" for short). The positions of the various middle fabric layers in the core body are also relatively fixed. Accordingly, compared with the conventional multi-layer simple "stacked" structure, the three-dimensional support member under this structural construction of the present application has greater strength and elasticity, and can provide better strength and support.

[0028] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

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

[0031] In order to solve the problem that the supporting member in the prior art is difficult to take into account the body-fitting property, comfort, strength and supporting force, this embodiment proposes a multi-layer non-metallic three-dimensional supporting member, as shown in the attached Figure 1-6 As shown, the three-dimensional support member 1 includes an outer fabric 2 and a transition isolation layer fabric 3 which are arranged in sequence from the outside to the inside, the outer fabric 2 is wrapped around the outside of 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 in 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, the present application sets up a multi-layer non-metallic fabric structure from the outside to the inside, and while the closed-loop cavity 6 is filled with a hot-melt medium 4, the hot-melt medium 4 is infiltrated into the middle fabric layer 5 and the transition isolation layer fabric 3 respectively, so that the three-dimensional support component 1 has good elasticity and a certain deformation ability during use at room temperature, so that the bra using the three-dimensional support component 1 has good body fit and comfort. On the other hand, the hot-melt medium 4 infiltrates the middle fabric layer 5 and the transition isolation layer fabric 3, and the fluidity of the hot-melt medium 4 disappears under normal temperature environment (or cooling), so that the hot-melt medium 4, the middle fabric layer 5, and the transition isolation layer fabric 3 are solidified into one (referred to as the "core body" for short), and the positions of each middle fabric layer 5 in the core body are relatively fixed. Accordingly, compared with the conventional multi-layer simple "stacked" structure, the three-dimensional support component under this structural structure of the present application has greater strength and elasticity, and can provide better strength and support.

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

[0034] 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 a hot-melt state is pressed into the transition isolation layer fabric 3, but at the same time is 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.

[0035] Accordingly, for any wall surface of the transition isolation layer fabric 3, the depth of penetration of the hot melt medium 4 into the transition isolation layer fabric 3 is less than the wall thickness of the transition isolation layer fabric 3. That is, in the present application, the hot melt medium 4 can only penetrate into the transition isolation layer fabric 3 and terminate inside the transition isolation layer fabric 3, and will not completely penetrate and pass through the transition isolation layer fabric 3, nor will it have any contact with the outer fabric 2, so that the outer fabric 2 will not undergo any changes in appearance or texture, and the appearance and touch quality of the entire three-dimensional support member 1 can be guaranteed. Accordingly, for the sake of ease of understanding, the present application defines this part of the hot melt medium 4 that penetrates into the transition isolation layer fabric 3 as the penetration medium 31.

[0036] There is a gap 7 between the outer fabric 2 and the transition isolation layer fabric 3, 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 there is a certain relative displacement space between the outer fabric 2 and the transition isolation layer fabric 3. When subjected to different external forces, the two can directly contact and fit, and can also be separated from each other, which can effectively meet the use effects under different curves and different force conditions, and help to broaden the scope of application of the three-dimensional support 1.

[0037] Alternatively, a viscose medium (not shown) is 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 are connected by the viscose medium, so that the two are relatively fixed and will not undergo relative displacement after being subjected to force, thereby better ensuring the tightness of the combination between the components of the three-dimensional support member 1 and ensuring the overall appearance smoothness and hand feel quality of the three-dimensional support member 1.

[0038] In order to facilitate the filling and penetration of the hot-melt medium 4 in the closed-loop cavity 6, the intermediate fabric layer 5 is a sheet structure with multiple through holes, and the density of the through holes is 400-1200 meshes, so that the hot-melt medium 4 after being melted by heat can not only penetrate into the interior of the intermediate fabric layer 5, but also flow relatively freely in the closed-loop cavity 6 through the through holes. On the one hand, it is convenient for hot pressing and shaping. During the pressing process, the hot-melt medium 4 will not be locally blocked or squeezed and damaged due to the inability of the local hot-melt medium 4 to flow freely. On the other hand, the hot-melt medium 4 can be distributed more evenly in the entire closed-loop cavity 6, which helps to ensure the homogenization of the elasticity and strength properties of the entire core body and the entire three-dimensional support member 1.

[0039] Preferably, 1-10 layers of intermediate fabric layers 5 are arranged in the closed-loop cavity 6, and there is a filling space between the intermediate fabric layer 5 and the inner wall of the transition isolation layer fabric 3, and / or there is a filling space between any two adjacent intermediate fabric layers 5. This ensures that the hot melt medium 4 can be filled between the intermediate fabric layer 5 and the transition isolation layer fabric 3, and between the two intermediate fabric layers 5, and ensures that the hot melt medium 4 is evenly distributed in the entire closed-loop cavity 6, so as to ensure excellent quality indicators such as elasticity and strength of the entire core.

[0040] The thickness of the middle fabric layer 5 is 0.1-0.5mm, the wall thickness of the transition isolation layer fabric 3 is 0.1-1mm, and the wall thickness of the outer fabric 2 is 0.2-1mm, which can not only effectively ensure the self-strength of each fabric, but also help to reduce its weight and occupied space as much as possible, so that the three-dimensional support member 1 can provide bra support while improving the user's physical comfort as much as possible.

[0041] As for the material of each fabric, existing fabric materials such as chemical fiber, cotton, linen, silk, etc. can be directly used, and this application does not impose too many restrictions. As for the hot-melt medium 4, it is a non-metallic material with fluidity after being melted by heat. Preferably, the hot-melt medium 4 is an organic polymer compound with a melting temperature greater than 100°C, including but not limited to PETG, PE, PP, PCL, PVA, TPU, etc., so as to facilitate hot pressing and shaping. At the same time, combined with the relevant technical solutions of the three-dimensional support member 1, it can also form a core body that meets the strength and elasticity requirements, and meet the quality requirements of bra products.

[0042] The overall shape of the three-dimensional support member 1 is the same as the shape of the human body corresponding to the position of the three-dimensional support member 1 on the bra. Figure 1-3 As shown, the three-dimensional support member 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 recorded as the E end, and the end of the third arc segment area 13 away from the second arc segment area 12 is recorded as the F end. The virtual boundary line between the first arc segment area 11 and the second arc segment area 12 is recorded as the M line, and the virtual boundary line between the second arc segment area 12 and the third arc segment area 13 is recorded as the N line. The first arc segment area 11 The first arc section 11 is twisted counterclockwise from the M line to the E end, and the twisting angle of the first arc section 11 is 35°-60°. The second arc section 12 is twisted counterclockwise from the N line to the F end, and the twisting angle of the second arc section 12 is 35°-60°, so that the three-dimensional support member 1 applied to the bra can better fit the shape of the human body, and improve the body-fitting and comfort of the bra. It should be noted that the first arc section 11, the second arc section 12, and the third arc section 13 are only regional divisions for the convenience of introduction, and the three-dimensional support member 1 is not divided into three independent sections.

[0043] Any normal cross section of the arc of the three-dimensional support member 1 is a quadrilateral, preferably a regular quadrilateral such as a rectangle or a rhombus, and any two adjacent sides are connected in a rounded transition manner. 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 member 1, the three-dimensional support member 1 undoubtedly has multiple normal cross sections according to the different positions of the normal cross sections, and the cross-sectional areas of all normal cross sections may be the same, 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 recorded as X, and the cross-sectional area of ​​the normal cross section with the smallest cross-sectional area is recorded as Y, (XY) / Y≤0.6. This allows the three-dimensional support member 1 to be more in line with the shape of the human body and to set an appropriate cross-sectional size relationship, which helps to optimize the force distribution on the three-dimensional support member 1 and is beneficial to improving the strength and overall supporting force of the three-dimensional support member 1.

[0045] On this basis, refer to the attached Figure 6, the width of the normal cross section is recorded as W, the thickness of the normal cross section is recorded as h, 5mm≤W≤12mm, 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 member 1 can take into account various application requirements such as lightness, elasticity, strength, and support, and also help to further optimize the force distribution on the entire three-dimensional support member 1, providing better strength and support.

[0046] In the present invention, any bra can include the three-dimensional support member 1 described in this embodiment, and on the basis of the relevant technical solutions provided in this embodiment, the bra also includes conventional components including structures such as cups, and since these conventional components are all prior art, they will not be described in detail here. At the same time, the arrangement and assembly of the three-dimensional support member 1 of the present application in the bra can also adopt the prior art, and will not be described in detail.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
