Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear and apparel technology, specifically to a flyknit upper for a spliced 3D printed shoe upper that is easy to color-match. Background Technology
[0002] Shoes are a type of clothing accessory whose function is to protect and wrap around the user's feet. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, while the upper is the upper part of the sole. The upper wraps around the user's foot and connects with the sole to fix it to the user's foot, preventing the sole from slipping off. The design of the upper can effectively improve the integration of the shoe and foot, and make the shoe more protective and cold-proof. Flyknit uppers are a type of upper, manufactured through a flyknitting process. They have good flexibility and fit. Through layers of flyknitting, a special texture is formed, which effectively improves the aesthetics and tensile strength.
[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: when dyeing existing flyknit uppers, the only way is to mix the desired color yarn into the flyknit yarn of the flyknit upper and then precisely weave it to achieve the desired color and pattern. This requires precise control of the yarn ratio and flyknit trajectory to form the desired color and pattern, which is very difficult to process. At the same time, because the colored yarn is mixed in, the proportion of high-strength yarn is reduced, making it difficult to guarantee the strength of the upper. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a flyknitted shoe upper that is easy to mold colors and patterns, has high upper strength, and is easy to color-match.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a 3D-printed shoe upper for easy color matching and splicing, comprising a 3D-printed shoe upper body, wherein the 3D-printed shoe upper body is provided with a 3D-printed shoe upper, the 3D-printed shoe upper includes a 3D-printed shoe upper body with through holes and a first UV printing layer cured on the bottom surface of the 3D-printed shoe upper body, wherein the bottom surface of the first UV printing layer is provided with a hot melt adhesive layer for fixed connection with the 3D-printed shoe upper body.
[0006] A further improvement is that a heel reinforcement upper is sewn onto the heel of the foot.
[0007] A further improvement is that a heel stabilizer is fixedly provided at the bottom edge of the heel-reinforced upper.
[0008] A further improvement is that a reinforcing hot-melt patch is provided at the position where the shoelaces are connected on the flyknit upper body.
[0009] A further improvement is that the edge of the 3D printed shoe upper body is provided with an edge reinforcement layer that simultaneously covers the edge of the flyknit shoe upper body.
[0010] A further improvement is that the upper surface of the 3D printed shoe upper is also provided with a 3D printed strength reinforcement layer.
[0011] A further improvement is that a second UV-printed layer is cured and formed on the lower surface of the strength-enhancing layer.
[0012] A further improvement is that the edge of the strength-enhancing layer is also provided with a decorative pattern.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model attaches a 3D printed layer to the flyknit upper body and cures a first UV printing layer under the 3D printed upper body. The color and pattern carried by the first UV printing layer are made to shine upward to the 3D printed upper body, thereby enabling the upper to produce the required color and pattern. The processing is simple and has few steps, while effectively improving the strength of the upper and making it safer to wear. Attached Figure Description

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0018] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a 3D-printed shoe upper for easy color matching and splicing, comprising a 3D-printed shoe upper body 1, wherein a 3D-printed shoe upper 2 is provided on the 3D-printed shoe upper body 1, the 3D-printed shoe upper 2 comprising a 3D-printed shoe upper body 21 with through holes and a first UV printing layer 23 cured on the bottom surface of the 3D-printed shoe upper body 21, wherein a hot melt adhesive layer 22 for fixed connection with the 3D-printed shoe upper body 1 is provided on the bottom surface of the first UV printing layer 23. In use, the required color and pattern of the shoe upper body are first determined, and the color and pattern are input into a UV printing machine, and then... A 3D printer is used to form the 3D printed shoe upper body 21 of the 3D printed shoe upper 2 in one step. Then, the 3D printed shoe upper body 21 is fed into a UV printer to cure and form the first UV printing layer 23. Then, a hot melt adhesive layer 22 is set on the lower surface of the first UV printing layer 23. After the hot melt adhesive layer 22 is heated, it is fixedly attached to the required position of the flyknit shoe upper body 1. At this time, the pattern and color carried by the first UV printing layer can be seen through the 3D printed shoe upper body. The processing is simple and has few steps. At the same time, the 3D printed shoe upper 2 attached to the flyknit shoe upper body 1 can effectively improve the tensile and torsional strength of the shoe upper, making it safer to wear.
[0019] The flyknit upper body 1 is sewn to the heel reinforcement upper 4 at the position of the human foot heel. The heel reinforcement upper 4 is filled with sponge, which is beneficial to provide stronger protection for the wearer's heel and fit the user's heel better when wearing, and is less likely to cause heel tilting and foot injury.
[0020] The heel-reinforced upper 4 is fixedly provided with a heel stabilizer 5 at the bottom edge, which helps to improve the stability of the heel area of the upper and further avoids heel tilting and foot injury.
[0021] The flyknit upper body 1 is provided with a reinforcing hot melt patch 3 at the shoelace connection position, which is beneficial to the tensile strength of the flyknit upper body 1 at the shoelace connection position, and thus is less likely to crack after the shoelaces are inserted and tightened.
[0022] The edge of the 3D printed upper body 21 is provided with an edge reinforcement layer 260 that simultaneously covers the edge of the flyknit upper body 1. This helps to make the edge of the upper stronger after it is installed on the midsole, making it less prone to cracking under the stress of movement and making the connection more stable.
[0023] The upper surface of the 3D printed shoe upper body 21 is also provided with a 3D printed strength reinforcement layer 24, which can be 3D printed using relatively hard materials such as TPU, which is beneficial to improve the strength of the 3D printed shoe upper body 21 and enhance its sense of layering.
[0024] The second UV printing layer 25 is cured and formed on the lower surface of the strength reinforcement layer 24, which is beneficial to the strength reinforcement layer 24 to produce colors and patterns through the second UV printing layer 25, making it more beautiful.
[0025] The edge of the strength reinforcement layer 24 is also provided with a decorative layer 26, which helps to cover the connecting edge of the strength reinforcement layer 24 through the decorative layer 26, making it more aesthetically pleasing and preventing the edge of the strength reinforcement layer 24 from being directly exposed, thus extending its service life.
[0026] The working principle of this utility model is as follows: First, the required color and pattern of the shoe upper body are determined and input into a UV printing machine. Then, the 3D printed shoe upper body 21 of the shoe upper 2 is formed in one step using a 3D printer. The 3D printed shoe upper body 21 is then fed into the UV printing machine to solidify and form the first UV printing layer 23. A hot melt adhesive layer 22 is then placed on the lower surface of the first UV printing layer 23. After heating, the hot melt adhesive layer 22 is fixedly attached to the required position on the flyknit shoe upper body 1. At this point, the pattern and color carried by the first UV printing layer can be seen through the 3D printed shoe upper body. The processing is simple and involves few steps. Simultaneously, the 3D printed shoe upper 2 attached to the outside of the flyknit shoe upper body 1 can effectively improve the tensile and torsional strength of the shoe upper, resulting in higher safety when worn.
