Description

Technical Field

[0001] This utility model relates to printed shoe uppers, and more particularly to a multi-angle color-changing three-dimensional printed shoe upper. Background Technology

[0002] 3D printed shoe uppers are a process that involves directly printing patterns or textures onto shoe upper materials in a three-dimensional form. Currently, the colors in printed shoe uppers are mainly used on the surface coating for aesthetic purposes, and the surface color layer is relatively thin. During movement, the colors only undergo simple spatial movement, resulting in relatively simple changes and minimal visual impact from movement.

[0003] Existing technology, such as the novel multi-layer three-dimensional offset printing shoe upper disclosed in Chinese Patent Publication No. CN119157338A, includes a base shoe upper and multiple multi-layer three-dimensional offset printing layers. The base shoe upper has several multi-layer three-dimensional offset printing layers, each comprising a base layer and several silicone bodies, with silicone bodies of different heights arranged on the base layer. However, in this technology, only one color is used within the same height of the multi-layer three-dimensional offset printing layers, and due to the low thickness of the color layers, the color change is monotonous during movement. Utility Model Content

[0004] (a) Technical problems to be solved To address the technical problem of limited color variation in existing 3D printed shoe uppers, this invention provides a multi-angle color-changing 3D printed shoe upper.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: A multi-angle color-changing three-dimensional printed shoe upper includes: a base fabric and a plurality of multi-color three-dimensional coatings disposed on the base fabric. The multi-color three-dimensional coatings include an underlayer, a first multi-color layer, a transparent layer, a second multi-color layer, a connecting layer, a single-color layer, and a protective layer disposed sequentially along the height direction. Two or more different colors are distributed on the horizontal plane of the first multi-color layer and the second multi-color layer, and the color settings, distribution positions, and sizes of the first multi-color layer and the second multi-color layer are the same.

[0006] Preferably, the pattern shapes and sizes of the base layer, the first multi-color layer, the transparent layer, the second multi-color layer, the connecting layer, and the single-color layer are the same.

[0007] Preferably, the thickness of the transparent layer is 0.2-1.2 mm.

[0008] Preferably, both the base layer and the connecting layer are transparent, and the thickness of the base layer and the connecting layer is 0.05-0.2mm.

[0009] Preferably, the protective layer is arc-shaped and covers the outer side of the base layer, the first multi-color layer, the transparent layer, the second multi-color layer, the connecting layer, and the monochromatic layer.

[0010] Preferably, the thickness of the first multicolor layer and the second multicolor layer is 0.05-0.1 mm.

[0011] Preferably, the color of the monochrome layer is different from that of the first multicolor layer and the second multicolor layer.

[0012] Preferably, the colors of the first and second multicolor layers are one or more combinations of fluorescent colors, luminous colors, metallic colors, etc.

[0013] (III) Beneficial Effects The beneficial effects of this utility model are as follows: by adopting the above technical solution, the base layer fills and flattens the surface of the substrate, providing a flat printing platform for subsequent printing; the first multi-color layer and the second multi-color layer correspond in color through the transparent layer, presenting a visually high color layer effect; the connecting layer connects and separates the second multi-color layer and the single-color layer, making the colors of the two independent of each other. Finally, different colors of the first multi-color layer / second multi-color layer can be seen from different positions on the side of the multi-color three-dimensional coating, and the color of the single-color layer can be seen on the top of the multi-color three-dimensional coating, realizing a three-dimensional printing effect with multi-angle color change, diverse color changes, and more natural and obvious multi-color effect changes during movement.

[0016] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Please refer to Figure 1 This embodiment provides a multi-angle color-changing three-dimensional printed shoe upper, including a base fabric 1 and several multi-color three-dimensional coatings printed on the base fabric 1. Along the direction away from the base fabric 1, the multi-color three-dimensional coatings include a base layer 2, a first multi-color layer 3, a transparent layer 4, a second multi-color layer 5, a connecting layer 6, and a protective layer 8, which are printed sequentially.

[0018] Specifically, the base coat 2 is printed with a base paste, the main component of which is transparent water-based polyurethane, with a thickness of 0.05-0.2mm. The base coat 2 fills in the mesh and surface texture of the base fabric 1, achieving a smooth surface to facilitate subsequent printing.

[0019] Please refer to Figure 1 and Figure 2 The first multicolor layer 3 and the second multicolor layer 5 are printed with a paste, which is a mixture of water-based polyurethane and color powder, photochromic powder, luminescent powder, or pearlescent powder, etc., and the color is one or more combinations of fluorescent color, luminescent color, metallic color, etc. In this embodiment, the first multicolor layer 3 and the second multicolor layer 5 have two colors, pink and green, and the color distribution positions and sizes of the two are corresponding. Since the colored paste has a low solid content, it is difficult to apply a thick coating. Therefore, the first multicolor layer 3 and the second multicolor layer 5 are 0.05-0.1mm thick, and two different colored pastes are applied thinly to make the two colors independent and avoid color mixing that would affect the effect.

[0020] Please refer to Figure 1 A transparent layer 4 is positioned between the first multi-color layer 3 and the second multi-color layer 5, and is printed using transparent water-based polyurethane with a thickness of 0.2-1.2 mm. The colors of the first multi-color layer 3 and the second multi-color layer 5 correspond to each other through the transparent layer 4, creating a visually substantial color layer effect. This significant thickness solves the problem of printing different colors at the same position in the 3D printing field. Furthermore, different color variations can be observed at the same height of the multi-color 3D coating, meaning that different colors of the first multi-color layer 3 and the second multi-color layer 5 can be seen from different angles on the side of the multi-color 3D coating.

[0021] Please refer to Figure 1 The connecting layer 6 is printed on top of the second multi-color layer 5 with transparent water-based polyurethane. Its thickness is the same as that of the underlay layer 2, which is 0.05-0.2mm. The connecting layer 6 is used to connect the second multi-color layer 5 and the single-color layer 7, and at the same time, it plays a role in color isolation to prevent the single-color layer 7 from damaging the edge of the second multi-color layer 5 during printing and affecting the color-changing effect.

[0022] Please refer to Figure 1 The monochrome layer 7 has the same pattern position and size as the first multicolor layer 3 and the second multicolor layer 5, and is also printed with a paste, which is a mixture of water-based polyurethane and color powder, photochromic powder, luminescent powder, or pearlescent powder. In this embodiment, the monochrome layer 7 is white and has a thickness of 0.05-0.1mm. The monochrome layer 7 is located above the first multicolor layer 3 and the second multicolor layer 5, and can cover the colors of the first multicolor layer 3 and the second multicolor layer 5, so that the color of the monochrome layer 7 can be seen above the multicolor three-dimensional coating, realizing a three-dimensional printing effect with multi-angle color change. The color changes are diverse, and the multicolor effect changes more naturally and obviously during movement.

[0023] Please refer to Figure 1 The protective layer 8 is made of transparent water-based polyurethane printed using a stencil, with the stencil cutout size larger than that of the base layer 2, the first multi-color layer 3, the transparent layer 4, the second multi-color layer 5, and the connecting layer 6. Under the influence of gravity, the water-based polyurethane flows outward and extends, eventually forming an arc shape that covers the outside of the base layer 2, the first multi-color layer 3, the transparent layer 4, the second multi-color layer 5, the connecting layer 6, and the single-color layer 7. On the one hand, this provides better protection for the multi-color three-dimensional coating, improving overall performance, especially significantly improving the tensile strength reduction problem caused by some high proportions of pigments and fillers; on the other hand, the arc shape also makes the overall feel smoother and more comfortable.

[0024] In summary, please refer to Figure 1 The multi-color three-dimensional coating presents different color effects when viewed from different angles. Firstly, pink and green color changes can be seen from different sides, while a white monochrome layer 7 can be seen from above, achieving a multi-angle color-changing effect. Furthermore, depending on the design, different color combinations or different thicknesses of the transparent layer 4 can be used in different areas of the same base fabric 1 to achieve different three-dimensional color-changing effects. When this embodiment is made into a complete shoe, it will bend to varying degrees with human movement, making the colors of the multi-color three-dimensional coating more obvious and easier to visually capture.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
