Description

Technical Field

[0001] The utility model relates to a pair of shoes, in particular to a midsole structure and the shoes. Background Art

[0002] For a pair of shoes, in addition to being comfortable to wear, the lightness has gradually attracted the attention of the majority of users. Shoes include structural components such as soles, midsoles and uppers. The midsoles of the shoes have different molding methods according to different manufacturing processes, such as supercritical foaming midsoles, popcorn midsoles, EVA midsoles, etc. After the traditional midsoles are manufactured, they are wrapped with cloth, which plays a role in dirt resistance and wear resistance. However, the traditional cloth wrapping process will cause the heels to wrinkle easily. If a pattern is set, the pattern will float on the surface, and there is a potential delamination problem. After the secondary hot pressing, there is a problem of hardening of the side walls, resulting in poor overall quality of the shoes. For supercritical foaming midsoles and popcorn midsoles, their dirt resistance has always been a thorny problem. Only with the current cloth wrapping process, its dirt resistance and wear resistance are increasingly difficult to meet people's use needs. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a shoe midsole structure and a shoe with stronger wear resistance and dirt resistance.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A shoe midsole structure comprises a midsole body, wherein the midsole body is a supercritical foamed midsole, the outer surface of the midsole body is covered with a meltblown cloth, the meltblown cloth has the same size as the midsole body, the meltblown cloth and the midsole body are hot-pressed in a mold, and the outer surface of the meltblown cloth is provided with a decorative layer.

[0006] As a further improvement, the decorative layer is a pattern, and the pattern is formed on the surface of the meltblown cloth by laser engraving or digital printing.

[0007] As a further improvement, the meltblown cloth is made of TPU material, and the midsole body is made of TPU material. The meltblown cloth and the midsole body are fused during the hot pressing molding process in the mold, so that the meltblown cloth is completely adhered to the midsole body.

[0008] As a further improvement, the meltblown cloth is provided with a plurality of micropores, and during the hot pressing process of the meltblown cloth and the midsole body in the mold, part of the material of the midsole body will flow into the micropores, so that the meltblown cloth and the midsole body are firmly connected.

[0009] As a further improvement, the micropores on the meltblown cloth are formed by laser drilling and are distributed in an array.

[0010] As a further improvement, the decorative layer on the meltblown cloth includes one pattern or two or more different patterns.

[0011] As a further improvement, the meltblown cloth is provided with one color or two or more different colors.

[0012] As a further improvement, the midsole body is a solid structure.

[0013] As a further improvement, an air cavity is provided in the midsole body.

[0014] As a further improvement, the air cavity is a sealed cavity formed in the midsole body, and at least one of the air cavity is provided.

[0015] Compared with the prior art, the utility model has the following beneficial technical effects:

[0016] By hot-pressing the midsole made of TPU melt-blown cloth and supercritical foaming of TPU material, the melt-blown cloth can be better integrated with the midsole. TPU melt-blown cloth has excellent wear resistance, high tension and high tensile strength, and has good oil resistance and breathability, so it is more compatible with the midsole material than the traditional TPU-wrapped midsole / cloth-wrapped midsole, and there is no wrinkle on the heel. The surface pattern UV printing is environmentally friendly and can be made in bright colors and fluorescent colors. The midsole of this invention process package has a surface pattern that can be dissolved with the midsole, the pattern is clear in appearance, and the position of the heel with a large curvature is completely wrinkle-free, which fits the midsole better. The hot pressing of the TPU melt-blown cloth wrapped midsole can not only meet the customer's requirements for appearance, but also does not affect the hardness of the edge drywall, so that its comprehensive performance is more optimized, and at the same time, the service life of the material is improved.

[0025] like Figure 1 and 2 As shown, a shoe midsole structure includes a midsole body 1, the midsole body 1 is a supercritical foaming midsole, the outer surface of the midsole body 1 is covered with a meltblown cloth 2, the meltblown cloth 2 is the same size as the midsole body 1, the meltblown cloth and the midsole body are hot-pressed in a mold, and the outer surface of the meltblown cloth 2 is provided with a decorative layer 3. The midsole body 1 and the meltblown cloth 2 are both made of TPU material. Since they are the same material, they can be better fused with each other during hot-pressing in the mold to ensure adhesion. TPU meltblown cloth has excellent wear resistance, high tension and high tensile strength, and has good oil resistance, air permeability, and no wrinkles on the heel. The surface pattern UV printing is environmentally friendly and can be made into bright colors and fluorescent colors. The midsole of this invention process package has a surface pattern that can be dissolved with the midsole, the pattern is clear in appearance, and the position with a large curvature of the heel is completely wrinkle-free, which fits the midsole better. The hot pressing of TPU melt-blown cloth wrapped in the midsole can not only meet the customer's requirements for appearance, but also does not affect the hardness of the edge drywall, making its comprehensive performance more optimized and at the same time increasing the service life of the shoe component product.

[0026] The decorative layer 3 is a pattern, which is formed on the surface of the meltblown cloth by laser engraving or digital printing. Only one pattern can be printed, or a combination of multiple different patterns can be printed. In the molding process in the mold, since the meltblown cloth and the midsole body are both made of TPU material, the same material is conducive to fusion, so that the pattern on the meltblown cloth can also be well dissolved with the midsole body.

[0027] The meltblown cloth 2 and the midsole body 1 are fused during the hot pressing process in the mold, so that the meltblown cloth is completely attached to the midsole body. During the processing, the mold is heated and vulcanized, and then cooled and shaped, so that the meltblown cloth is completely attached to the surface of the midsole body.

[0028] In addition, the meltblown cloth is provided with a number of micropores, and during the hot pressing process of the meltblown cloth and the midsole body in the mold, part of the material of the midsole body will flow into the micropores, so that the meltblown cloth and the midsole body are tightly connected. Through the setting of the micropores, during the hot pressing process in the mold, the combination of materials will be more firm, forming a stronger pulling force, so that the meltblown cloth will not easily fall off from the surface of the midsole body, thereby improving the quality of the product.

[0029] The micropores on the meltblown cloth are formed by laser drilling and are distributed in an array, and the diameter of the micropores is usually less than 1 mm.

[0030] In addition, the meltblown cloth is provided with one color or two or more different colors, which can be flexibly selected according to the purpose of the shoes to enhance the decorative effect.

[0031] The midsole body 1 is a solid structure. Figure 2 Or, an air cavity 4 is provided in the midsole body 1, and the number of the air cavity can be one or more to improve the shock absorption, such as Figure 3 shown.

[0032] It should be noted that the above are only 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 aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
