Description

Technical Field

[0001] This utility model relates to the field of footwear materials, specifically to an infused shoe upper structure with a patterned film. Background Technology

[0002] The following are some methods for achieving patterns or gradient colors in shoe uppers by infusing liquid materials (PU, KPU, CPU, GCU):

[0003] 1) Integrated Pattern and Injection Molding: 1. Print the pattern onto mesh fabric, leather, or onto the surface of a film to form a base material layer; 2. Inject transparent or semi-transparent KPU, CPU, or GCU liquid into the mold to form a preliminary surface structure layer; 3. Vacuum the surface structure layer; 4. Scrape off excess material from the mold surface; 5. Heat to solidify the liquid, obtaining the surface structure layer; 6. Cover the surface structure layer with the patterned base material layer, press, and heat to continue curing. This structure forms a three-layer structure, namely, from top to bottom, a transparent or semi-transparent surface structure layer, a pattern, and a base material layer. The surface structure layer completely covers the pattern, meaning the pattern is the bottom layer. Disadvantages: The pattern is visible through the transparent or semi-transparent surface structure layer, the transparent material layer constituting the surface structure layer is prone to yellowing, and the material cost is relatively high. Steps 4 and 5 are required for a clear bond between the surface and bottom layers.

[0004] 2) First form, then process the pattern; 1. First, make a monochrome product using steps 2-6 above; 2. Process the surface of the finished product; 3. Apply cold transfer printing, heat absorption coating, or positioning printing of patterns or colors to the surface. Disadvantages: The surface needs to be processed first, which can easily lead to yellowing of the shoe surface; it increases the processing and cost of surface processing and component placement. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an infused shoe upper structure with a patterned film coating, which saves manufacturing costs and is less prone to fading.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A patterned film-coated infused shoe upper structure includes a base layer and a pattern, wherein a hot melt adhesive film is provided on the decorative layer, and the decorative layer is hot melt bonded to the upper surface of the base layer by the hot melt adhesive film.

[0008] As a further improvement, the decorative layer includes a fabric base on which a pattern layer is printed, and the fabric base is cut to the same size as the decorative layer.

[0009] As a further improvement, the hot melt adhesive film is applied to the bottom surface of the fiber fabric substrate, located on one side of the bottom surface of the pattern layer, or the hot melt adhesive film is applied to the upper surface of the pattern layer, covering the decorative layer.

[0010] As a further improvement, the pattern layer includes one or at least two combinations of patterns, colors, and mesh textures.

[0011] As a further improvement, the fiber cloth base is made of fiber cloth with a unit area mass of 50-90G and a bursting force of more than 13KG.

[0012] As a further improvement, the underlying layer is made by infusion of PU, KPU, CPU or GCU material.

[0013] As a further improvement, the thickness of the hot melt adhesive film is 0.05-0.15 mm.

[0014] As a further improvement, the area of ​​the decorative layer is smaller than the area of ​​the base layer.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] The decorative layer and the bottom layer are directly heat-fused together to form a two-layer structure, which saves preparation steps and reduces production costs. The surface has an exposed pattern, and the bottom layer is a potting material layer. The whole structure is a double layer, which makes it less likely to cause surface yellowing and discoloration.

[0024] like Figure 1 and 2 As shown, a patterned film-coated infused shoe upper structure includes a base layer 1 and a decorative layer 2. The decorative layer 2 has a hot-melt adhesive film on it, and is thermally bonded to the upper surface of the base layer 1 via the hot-melt adhesive film. The base layer is made of PU, KPU, CPU, or GCU material, and the decorative layer serves as the upper structure. This is the opposite of the traditional method of using a material layer made of PU, KPU, CPU, or GCU material as the upper layer of the shoe upper. By using the decorative layer as the upper layer, the decorative layer is directly visible, eliminating the need for a transparent layer, thus reducing the likelihood of the base layer yellowing or fading. The two layers are thermally bonded together via the hot-melt adhesive film to form a single, integrated structure.

[0025] The decorative layer 2 includes a fabric base on which a pattern layer is printed. The fabric base is cut to the same size as the decorative layer.

[0026] The hot melt adhesive film is applied to the bottom surface of the fiber fabric substrate, located on one side of the bottom surface of the pattern layer, forming a matte effect; or the hot melt adhesive film is applied to the upper surface of the pattern layer, covering the clothing pattern layer, forming a glossy effect.

[0027] The pattern layer includes one or more combinations of patterns, colors, and mesh textures. The patterns may be three-dimensional and may include different colors.

[0028] In addition, the fiber cloth base is made of fiber cloth with a unit area mass of 50-90G and a bursting force of more than 13KG to ensure durability.

[0029] The thickness of the hot melt adhesive film is 0.05-0.15 mm to ensure the hot melt bonding effect.

[0030] The area of ​​the decorative layer is smaller than that of the base layer. Different sizes of decorative layers can be set as needed to create different decorative effects.

[0031] The following methods can be used as a reference during preparation:

[0032] 1. Select a fiber cloth with a weight of 50-90g and a bursting force of 13KG or more as the fiber cloth base.

[0033] 2. Print the required patterns, colors, and mesh textures onto the fiber cloth, and also print the mold alignment holes onto the fiber cloth.

[0034] 3. Lay a 0.1mm high-temperature hot adhesive film over the printed fabric. If a glossy effect is required, laminate the film on top of the fabric pattern; if a matte effect is required, laminate the film on the back of the fabric pattern.

[0035] 4. Use a positioning laser to cut or manually cut the fiber cloth of the composite film into the required pattern to form a decorative layer.

[0036] 5. Hang the prepared decorative layer on the mold.

[0037] 6. Place the mold with the fabric attached into the vacuum machine. Keep the machine temperature between 40-55 degrees Celsius. Use the temperature to soften the fabric and hot melt film slightly, so that the material can adhere more tightly to the mold surface when the machine vacuums.

[0038] 7. Inject materials such as PU, KPU, CPU, and GCU to form the bottom layer.

[0039] 8. Cover with the lid and heat to form.

[0040] 9. Trim off any excess parts and rough edges to obtain the desired shoe upper.

[0041] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
