Description

Technical Field

[0001] The utility model relates to the technical field, and particularly relates to a fly-knit upper for a hot-melt 3D printed upper with high air permeability. Background Art

[0002] A shoe is a clothing accessory whose task is to protect and wrap the user's foot, and it basically consists of a sole and an upper. The sole is the lower part in contact with the ground, while the upper is the part arranged above the sole. The upper can wrap the user's foot and be connected to the sole to fix the sole on the user's foot and prevent the sole from falling off. The setting of the upper can effectively improve the shoe-foot integrity and make the shoe have better protection and cold-proof effects on the foot. A fly-knit upper is a type of upper, which is manufactured by the fly-knit process, has good flexibility and fit, and forms special textures through layer-by-layer fly-knitting, effectively improving the aesthetics and tensile properties.

[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: in order to make the fly-knit upper better colored, an additional colored sticker layer is provided on the upper surface of the fly-knit upper, and the color of the fly-knit upper is adjusted and the strength of the fly-knit upper is enhanced through the sticker layer. However, some of the existing sticker layers are fixed by hot-melt adhesive, and the hot-melt adhesive is filled between the fly-knit upper and the patch. After melting, it will cover the fly-knit upper in a large area, and the non-breathable hot-melt adhesive results in extremely poor air permeability of the processed fly-knit upper. When fixed by sewing, not only does it require sewing the patch into shape during processing, but also sewing the processed patch on the fly-knit upper, with many steps and cumbersome processing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fly-knit upper for a hot-melt 3D printed upper with good air permeability, simple processing and few steps in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: a fly-knit upper for a hot-melt 3D printed upper with high air permeability, including a fly-knit layer, a 3D printed patch formed by 3D printing is arranged on the fly-knit layer, and a hot-melt layer is arranged between the bottom surface of the 3D printed patch and the upper surface of the fly-knit layer, and the hot-melt layer is only distributed at the edge position of the bottom surface of the 3D printed patch.

[0006] Further improvement is: a plurality of through ventilation holes are arranged on the surface of the 3D printed patch.

[0007] Further improvement is: a reinforcing layer is arranged at the edge of the surface of the 3D printed patch.

[0008] Further improvement is: a plurality of exhaust holes are penetratively arranged on the surface of the area of the fly-knit layer covered by the 3D printed patch.

[0009] Further improvement: An enlarged hole in a spherical shape is provided at the middle position of the exhaust hole.

[0010] Further improvement: A breathable cavity is formed between the flyknit layer and the area of the 3D printed patch that is not covered by the hot melt layer.

[0011] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: The present utility model is provided with a 3D printed patch formed by 3D printing on the flyknit layer. There is no need to sew the patch into shape, and only a single 3D printing step is required for rapid processing and shaping. At the same time, the hot melt layer is only provided at the bottom edge of the 3D printed patch, so that the hot melt layer does not completely cover the bottom surface of the 3D printed patch, making the position not covered by the hot melt layer more breathable and ensuring the overall breathability of the shoe upper. Description of the Drawings

[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0014] Figure 2 It is a cross-sectional structural schematic diagram of the flyknit upper of the 3D printed shoe upper of the present utility model. Detailed Embodiment

[0015] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0016] Refer to Figure 1-2As shown in the figure, the technical solution adopted in this specific embodiment is as follows: a flyknit upper for a hot-melt 3D printed upper with high breathability, including a flyknit layer 1, on which there is a 3D printed patch 2 formed by 3D printing. There is a hot-melt layer 3 between the bottom surface of the 3D printed patch 2 and the upper surface of the flyknit layer 1. The hot-melt layer 3 is only distributed at the edge position of the bottom surface of the 3D printed patch 2. During processing, first, the 3D printed patch 2 is formed by one-time processing by a 3D printer, and the hot-melt layer 3 is set at its edge. Subsequently, the 3D printed patch 2 can be fixed on the flyknit layer 1 by hot-pressing the hot-melt layer 3. The 3D printed patch 2 does not need to be sewn into shape, and only a single 3D printing step is required to quickly process and form it. At the same time, the hot-melt layer 3 is only set at the bottom edge of the 3D printed patch 2, so that the hot-melt layer 3 does not completely cover the bottom surface of the 3D printed patch 2, making the position not covered by the hot-melt layer 3 more breathable and ensuring the overall breathability of the upper;

[0017] There are several through ventilation holes on the surface of the 3D printed patch 2, which is beneficial to further improve the surface breathability of the 3D printed patch 2;

[0018] There is a reinforcing layer 4 on the edge of the surface of the 3D printed patch 2, which is beneficial to make the edge strength and overall strength of the 3D printed patch 2 higher, and it is not easy to break from the edge when bent;

[0019] There are several exhaust holes 11 penetrating through the surface of the flyknit layer 1 in the area covered by the 3D printed patch 2, which is beneficial to improve the ventilation effect of the position of the flyknit layer 1 covered by the 3D printed patch 2;

[0020] There is an enlarged hole 12 in the shape of a sphere in the middle section of the exhaust hole 11, which is beneficial to make the air gather in the enlarged hole 12, and when the foot presses the flyknit layer 1, the enlarged hole 12 is flattened and the air is quickly discharged to take away heat. At the same time, when it returns to its original state, the outside cold air is pressed into the enlarged hole 12, so as to make the foot cooler;

[0021] There is a ventilation cavity 31 formed between the flyknit layer 1 and the area not covered by the hot-melt layer 3 of the 3D printed patch 2, which is beneficial to make the air diverge outward into the ventilation cavity 31, and through the ventilation cavity 31, the air can be accumulated and flowed, further improving the ventilation and heat dissipation effect of the upper.

[0022] Working principle of the utility model: When the utility model is in processing, firstly, the 3D printing patch 2 is integrally processed and formed by a 3D printer, and a hot melt layer 3 is arranged at its edge. Subsequently, the 3D printing patch 2 can be fixed on the flyknit layer 1 by hot pressing the hot melt layer 3. The 3D printing patch 2 does not need to be sewn and formed, and only a single 3D printing step is required to quickly process and form. At the same time, the hot melt layer 3 is only arranged at the bottom edge of the 3D printing patch 2, so that the hot melt layer 3 does not completely cover the bottom surface of the 3D printing patch 2, and the position not covered by the hot melt layer 3 has better air permeability, ensuring the overall air permeability of the shoe upper.
