Description

Technical Field

[0001] This utility model relates to the field of clothing and footwear processing technology, specifically to a decorative piece and shoes with a bridging surface. Background Technology

[0002] PVC decorative sheets are made by mixing PVC (polyvinyl chloride) resin with plasticizers and adding various performance modifiers, then curing under heat. Because molds and raw materials are inexpensive and readily available, they are very popular in the market. However, in actual use in the clothing and footwear industry, due to process limitations and the curing principle of PVC paste resin, PVC decorative sheets are prone to powdering and oiling, resulting in unstable product quality. They easily yellow under sunlight and tend to have a strong odor. Furthermore, because of their unstable physical properties, PVC decorative sheets are prone to color migration when combined with other materials and are easily contaminated by materials with poor colorfastness.

[0003] TPU decoration is a process in which TPU (thermoplastic polyurethane elastomer) granules are melted into the injection molding machine nozzle and then injected into the injection mold under pressure to create the finished product. This process is relatively mature and the product quality is stable. However, the softness of the product cannot reach that of PVC. In addition, the product is often accompanied by high mold costs, equipment costs, and labor costs.

[0004] Therefore, there is an urgent need to design a decorative sheet that is environmentally friendly, low-cost, highly adhesive, tear-resistant, and offers a variety of surface textures. Utility Model Content

[0005] To address the problems of existing PVC decorative sheets, such as yellowing, oiling, powdering, odor, unstable physical properties leading to delamination and color migration, and the technical issues of TPU decorative sheets requiring high-cost molds and complex injection molding processes, resulting in insufficient product softness and difficulty in meeting lightweight requirements, this utility model provides a decorative sheet and shoe with a bridging surface. As a decorative accessory for clothing, footwear, bags, and other fields, it has multiple advantages such as environmental friendliness, low cost, high adhesion, tear resistance, and diverse surface textures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a decorative sheet with a bridging surface, including a decorative sheet substrate layer, a front bridging surface layer and a back bridging surface layer;

[0008] The decorative sheet substrate layer is made of silicone, and the front and back sides of the decorative sheet substrate layer are respectively fixedly laminated with the front bridging layer and the back bridging layer.

[0009] The back bridging layer includes a first bridging layer and a first base layer formed sequentially. The front bridging layer includes a decorative layer and a second base layer formed sequentially. Both the first base layer and the second base layer are base fabric layers with microporous permeable structures. The front and back sides of the decorative sheet substrate layer are integrally formed with the second base layer and the first base layer, respectively. The back side of the decorative sheet substrate layer, which is in a molten state, is impregnated and penetrates into the microporous gaps of the first base layer and is cured, thereby fixing the first base layer to the back side of the decorative sheet substrate layer. The front side of the decorative sheet substrate layer, which is in a molten state, is impregnated and penetrates into the microporous gaps of the second base layer and is cured, thereby fixing the second base layer to the front side of the decorative sheet substrate layer.

[0010] The above technical solution is adopted:

[0011] This invention addresses the issue that PVC materials suffer from unstable performance, are prone to oiling and powdering due to manufacturing process problems, and most importantly, easily develop an unpleasant odor in the finished product. To resolve this issue, this application uses addition-cured odorless silicone material as the base layer for the decorative sheet. However, because the performance of silicone decorative sheets is too stable, many processing agents and adhesives cannot effectively treat silicone, resulting in silicone decorative sheets not being able to bond well with the fabrics of clothing and footwear products. To address this issue, this application employs a back bridging layer that is tightly bonded to the back of the decorative sheet substrate layer. This allows for a tight bond between the decorative sheet and the bridging layer, utilizing the high adhesiveness of the back bridging layer to bond with other fabrics. The back bridging layer is designed with a structure including a first bridging layer and a first base layer. During the integral molding process of the first base layer and the back of the decorative sheet substrate layer, the liquid decorative sheet substrate layer material (silicone) impregnates and penetrates into the micropores of the bottom fabric layer of the first base layer. In the subsequent curing process, this tightly bonds the first base layer to the back of the decorative sheet substrate layer, preventing detachment and enhancing adhesion strength. This also prevents delamination. Finally, the easy-to-adhere material of the first bridging layer is used to bond and composite with other fabrics, thus solving the problem of poor adhesion between silicone and fabrics.

[0012] Furthermore, since the surface texture of current decorative sheets is inferior to that of leather and other special-process fabrics, this application aims to improve the surface texture of decorative sheets by adding a bridging surface to enhance the texture. The front bridging layer is placed in the intended position before the decorative sheet is cured, allowing the texture-enhancing front bridging layer to solidify into the decorative sheet. In the specific preparation process, the texture-enhancing front bridging layer is placed in the groove of the surface-texturing material area of ​​the mold. The front bridging layer includes a decorative layer, which is a texture-enhancing fabric with a special texture. A second base layer is provided on the inner side of the decorative layer. The second base layer is made of linen, knitted fabric, or a thick material with capillary gaps as the base fabric. During the preparation process, a liquid material (silicone material) is poured in, allowing the liquid silicone material to come into contact with and fused with the second base layer, finally curing to form a decorative sheet with improved surface texture.

[0013] Furthermore, an anti-stretch layer is provided between the back of the decorative sheet substrate layer and the first base layer, and the anti-stretch layer is an anti-stretch mesh layer with pores.

[0014] Since addition-curing silicone is selected as the material in this application, the product is very brittle and easily torn and damaged. In order to solve the tearability of the decorative sheet, an anti-stretch layer (tear-resistant fabric layer) is added between the back of the decorative sheet substrate layer and the back bridging layer. Specifically, the anti-stretch layer is a gapped anti-stretch fabric that can be easily impregnated and passed through liquid materials.

[0015] Furthermore, the anti-stretch mesh layer is made of nylon, PP, polyurethane fiber, polyester, or spandex.

[0016] Furthermore, the base fabric layer is linen, knitted base fabric, or a material with capillary gaps.

[0017] Using linen, knitted fabric, or a thick material with capillary gaps as the base fabric, liquid silicone is then impregnated into the capillary gaps of the base fabric, and finally cured to form an integrated structure, thereby improving the bonding strength.

[0018] Furthermore, the first bridging layer is an adhesive material layer.

[0019] Specifically, the material of the first bridging surface layer is polyurethane, thermoplastic polyurethane elastomer, polyvinyl chloride, rubber, ethylene-vinyl acetate copolymer, thermoplastic rubber, genuine leather, fabric, artificial leather, or microfiber synthetic leather.

[0020] The first bridging layer is bonded to clothing, shoes, hats, and bags using an easy-to-adhere material, or it is fixed to clothing, shoes, hats, and bags by vulcanization or other adhesive methods.

[0021] Furthermore, the decorative layer is made of polymer polyurethane synthetic material, resin, genuine leather, or rubber.

[0022] In a second aspect, this utility model provides a shoe, including the aforementioned decorative piece, sole, and upper, wherein the shoe is assembled from the sole and upper, and the decorative piece is fixed to the upper of the shoe via a back bridging layer.

[0023] Furthermore, a bottom wall is provided around the outer side of the sole, and an installation groove is formed on the outer side of the bottom wall to be adapted to the welt. The welt is adapted to be installed in the installation groove, and the decorative piece is fixed to the outer side of the welt through a back bridging surface layer.

[0024] In practical applications, this decorative piece is fixed to the upper of the shoe or the welt on the side of the sole using an adhesive layer on the back bridging surface. Of course, this decorative piece can also be used on clothing, hats, and bags.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) In this application, the decorative sheet substrate layer is made of addition-cured odorless silicone material. However, due to the overly stable performance of silicone decorative sheets, many processing agents and adhesives cannot effectively treat the silicone, resulting in the silicone decorative sheets not being able to bond well with the fabrics of clothing and footwear products. To solve this problem, this application tightly cures and connects the back bridging layer to the back of the decorative sheet substrate layer, allowing the decorative sheet and the bridging layer to be tightly cured and connected. The high-efficiency adhesion of the back bridging layer is used to bond with other fabrics. The structure of the back bridging layer is designed, including a first bridging layer and a first base layer. During the integral molding process of the first base layer and the back of the decorative sheet substrate layer, the liquid decorative sheet substrate layer material (silicone) is impregnated and penetrates into the micropores of the bottom fabric layer of the first base layer. During the subsequent curing process, the first base layer and the back of the decorative sheet substrate layer are tightly connected and cannot be detached, improving the bonding strength and making it less prone to delamination. Then, the easy-to-adhere material of the first bridging layer is used to bond and composite with other fabrics, solving the problem of poor adhesion between silicone and fabric.

[0027] (2) In this application, in order to improve the surface texture of the decorative sheet, a bridging surface for improving the surface texture is added to the surface of the decorative sheet. The front bridging surface layer is placed in the intended position in advance while the decorative sheet is not cured, so that the front bridging surface layer with improved surface texture is cured into the decorative sheet. In the specific preparation, the front bridging surface layer for improving the surface texture is placed in the groove of the material area for improving the surface texture of the mold. The front bridging surface layer includes a decorative layer, which is a fabric with improved texture and a special texture. The inner side of the decorative layer is provided with a second base layer. The second base layer is a base fabric made of linen, knitted base fabric or a thick material with capillary gaps. During the preparation process, liquid material (silicone material) is poured in, so that the liquid silicone material comes into contact with and is immersed and fused with the second base layer. Finally, it is cured to form a decorative sheet that can improve the surface texture.

[0028] (3) Since addition-curing silicone is selected as the material in this application, the product is very brittle and easily torn and damaged. In order to solve the tearability of the decorative sheet, an anti-stretch layer (tear-resistant fabric layer) is added between the back of the decorative sheet substrate layer and the back bridging surface layer. Specifically, the anti-stretch layer is a gapped anti-stretch fabric that can be easily impregnated and passed through liquid materials. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] This embodiment discloses a decorative piece with a bridging surface, such as... Figure 1 As shown, it includes a decorative sheet substrate layer 2, a front bridging layer 6, and a back bridging layer 3;

[0037] The decorative sheet substrate layer 2 is made of silicone. The front and back sides of the decorative sheet substrate layer 2 are respectively fixed with a front bridging layer 6 and a back bridging layer 3.

[0038] The back bridging layer 3 includes a first bridging layer 4 and a first base layer 5, which are sequentially composited. The front bridging layer 6 includes a decorative layer 7 and a second base layer 8, which are sequentially composited. Both the first base layer 5 and the second base layer 8 are base fabric layers with microporous permeable structures. The front and back sides of the decorative sheet substrate layer 2 are integrally formed with the second base layer 8 and the first base layer 5, respectively. The back side of the decorative sheet substrate layer 2, which is in a molten state, is impregnated and penetrates into the microporous gaps of the first base layer 5 and is cured, thus fixing the first base layer 5 to the back side of the decorative sheet substrate layer 2. The front side of the decorative sheet substrate layer 2, which is in a molten state, is impregnated and penetrates into the microporous gaps of the second base layer 8 and is cured, thus fixing the second base layer 8 to the front side of the decorative sheet substrate layer 2.

[0039] This invention addresses the issue that PVC materials suffer from unstable performance, are prone to oiling and powdering due to manufacturing process problems, and most importantly, easily develop an unpleasant odor in the finished product. To resolve this issue, the decorative sheet substrate layer 2 in this application uses addition-cured odorless silicone material. However, because the performance of silicone decorative sheets is too stable, many processing agents and adhesives cannot effectively treat silicone, resulting in silicone decorative sheets not being able to bond well with the fabrics of clothing and footwear products. To address this issue, this application employs a back bridging layer 3 that is tightly bonded to the back of the decorative sheet substrate layer 2. This allows the decorative sheet and the bridging layer to be tightly bonded together. The high-efficiency adhesiveness of the back bridging layer 3 is utilized to bond with other fabrics. The structure of the back bridging layer 3 is designed to include a first bridging layer 4 and a first base layer 5. During the integral molding process of the first base layer 5 and the back of the decorative sheet substrate layer 2, the liquid material (silicone) of the decorative sheet substrate layer 2 impregnates and penetrates into the micropores of the bottom fabric layer of the first base layer 5. In the subsequent curing process, the first base layer 5 is tightly connected to the back of the decorative sheet substrate layer 2 and cannot be detached, thus improving the bonding strength and preventing delamination. Furthermore, the easy-to-adhere material of the first bridging layer 4 is used to bond and composite with other fabrics, solving the problem of poor adhesion between silicone and fabrics.

[0040] Furthermore, since the surface texture of current decorative sheets is inferior to that of leather and other special-process fabrics, this application aims to improve the surface texture of decorative sheets by adding a bridging surface to enhance the texture. The front bridging layer 6 is placed in the intended position before the decorative sheet is cured, allowing the texture-enhanced front bridging layer 6 to cure into the decorative sheet 1. In the specific preparation process, the texture-enhancing front bridging layer 6 is placed in the surface-texturing material area groove of the mold. The front bridging layer 6 includes a decorative layer 7, which is a texture-enhancing fabric with a special texture. A second base layer 8 is provided on the inner side of the decorative layer 7. The second base layer 8 is made of linen, knitted fabric, or a thick material with capillary gaps as the base fabric. During the preparation process, liquid material (silicone material) is poured in, allowing the liquid silicone material to come into contact with and immerse the second base layer 8, finally curing to form a decorative sheet 1 with improved surface texture.

[0041] Among them, a tensile-resistant layer (not shown in the figure) is provided between the back of the decorative sheet substrate layer 2 and the first base layer 5. The tensile-resistant layer is a tensile-resistant mesh layer with pores.

[0042] Since addition-curing silicone is selected as the material in this application, the product is very brittle and easily torn and damaged. In order to solve the tearability of the decorative piece 1, an anti-stretch layer (tear-resistant fabric layer) is added between the back of the decorative piece substrate layer 2 and the back bridging surface layer 3. Specifically, the anti-stretch layer is an anti-stretch fabric with gaps that can be easily soaked and passed through liquid materials.

[0043] Specifically, the anti-stretch mesh layer is made of nylon, PP, polyurethane fiber, polyester, or spandex.

[0044] The base fabric layer is made of linen, knitted fabric, or a material with capillary gaps. Using linen, knitted fabric, or a thick material with capillary gaps as the base fabric, liquid silicone is impregnated into the capillary gaps of the base fabric. Finally, after curing, an integrated structure is formed, improving the bonding strength.

[0045] The first bridging layer 4 is an adhesive material layer. Specifically, the material of the first bridging layer 4 is polyurethane, thermoplastic polyurethane elastomer, polyvinyl chloride, rubber, ethylene-vinyl acetate copolymer, thermoplastic rubber, genuine leather, fabric, artificial leather, or microfiber synthetic leather. The first bridging layer 4 is bonded to clothing, shoes, hats, and bags using its easy-to-adhere properties, or it can be fixed to clothing, shoes, hats, and bags through vulcanization or other adhesive methods.

[0046] The decorative layer 7 is made of high-molecular polyurethane synthetic material, resin, genuine leather, or rubber.

[0047] The specific preparation process of decorative piece 1 is as follows:

[0048] First, select a 3D model and create a concave mold for this model that can be filled with liquid material. Design groove areas in the areas where the surface texture needs to be improved. Place the front bridging layer 6, which improves the surface texture, in the groove areas in advance. Then, pour uncured liquid silicone into this mold, allowing the liquid silicone material to fully contact and wet the second base layer 8 in the front bridging layer 6.

[0049] Then, cut and assemble the back bridging layer 3 according to the shape of the mold frame. Add an anti-stretch layer (anti-stretch mesh) between the back bridging layer 3 and the liquid silicone. The anti-stretch mesh is an anti-stretch cloth with gaps that can be smoothly impregnated and passed through the liquid silicone material. Then, cover the mold with the first base layer 5 of the back bridging layer 3, so that the liquid silicone material and the base cloth of the first base layer 5 are in full contact. Finally, put the assembly into the oven for curing or let it stand at room temperature for curing. After curing, demold the bridging surface and the base layer together to form a decorative piece 1 with an improved surface texture and a bridging surface with an assembly.

[0050] Example 2

[0051] This embodiment discloses a shoe, such as Figure 2 As shown, the shoe 9 includes the decorative piece 1, sole 10, and upper 13 as in Embodiment 1. The shoe 9 is assembled from the sole 10 and upper 13. A bottom wall 11 is provided around the outer side of the sole 10. An installation groove is formed on the outer surface of the bottom wall 11 to accommodate a welt 12. The welt 12 is fitted into the installation groove. The decorative piece 1 is fixed to the outer surface of the welt 12 via a back bridging layer 3. In practical applications, the decorative piece 1 is fixed to the upper 13 of the shoe 9 or the welt 12 on the side of the sole 10 via the adhesive material layer of the back bridging layer. Of course, the decorative piece 1 can also be applied to clothing, hats, and bags.
