[0002] The heel is an important part of the shoe. The heel not only is the supporting structure of the shoe, but also plays an important role in protecting the foot, improving the appearance, adapting to different scenes and providing functionality. Different shoe models and design requirements determine the specific shape, height and material selection of the heel. Among them, sports shoes and casual shoes are more applied in daily commuting, outdoor activities and sports places, and need to provide good support and comfort. At present, high-density EVA foam, TPU (thermoplastic polyurethane) or other hard materials are commonly used to enhance the stability and supportability of the heel. In order to improve the air permeability, air holes or hollow structures are added in some areas to promote air circulation. In the preparation process, various structures need to be bonded, sewn and treated. The preparation process is relatively complicated, and if solvent-based glue is used, it is easy to pollute the environment, and subsequent delamination or delamination problems may occur; at the same time, due to the adhesion of the glue, the material is difficult to separate after use, limiting the recycling value.

[0023] To explain the technical content, purposes and effects of the utility model in detail, the following will be explained in combination with the embodiments and the drawings.

[0024] Please refer to Figure 1 and Figure 2 A heel structure comprises a filling part 2 and a support part 1 arranged at the periphery of the filling part 2.

[0025] The support part 1 comprises a first fabric 11, a first hot melt adhesive film 12 and a second fabric 14 arranged in sequence.

[0026] The filling part 2 comprises a first fabric 11, a first hot-melt adhesive mesh film 12, the standing cotton 3 and a second fabric 14 arranged in sequence.

[0027] From the above description, the heel structure provided by the utility model has the advantages that the filling part comprises the standing cotton, the standing cotton can provide good air permeability and supportability, cooperates with the surrounding support structure, can form a heel structure with good supportability and air permeability, and further improves the deodorization performance. The closed pore structure of the EVA foam cotton limits air circulation, resulting in that moisture and heat in the shoe cannot be effectively discharged. The heel structure provided by the utility model does not need to use traditional EVA foam cotton, and the standing cotton with a specific structure arranged locally can provide sufficient support while ensuring good air permeability. Through the combination of the fabric, the hot-melt adhesive mesh film and the standing cotton, the composite can be realized under hot-pressing conditions, solvent-based glue is not needed, the problem that a large amount of volatile organic compounds (VOCs) are released by the solvent-based glue and harm the environment and human health can be effectively avoided, and the problem that the water-based environmentally friendly glue has low adhesive strength and is prone to glue opening can also be avoided. Since the composite can be realized under hot-pressing conditions and manual or mechanical sewing is not needed, the complex process is avoided, and the production efficiency is effectively improved. The heel structure is easy to disassemble, and then the materials can be separated and recycled, the waste materials can be reused, and the recycling value is high.

[0028] In one or more embodiments, the filling part comprises a first fabric 11, a first hot-melt adhesive mesh film 12, the standing cotton 3, a second hot-melt adhesive mesh film 13 and a second fabric 14 arranged in sequence. According to the thickness or model of the hot-melt adhesive mesh film, one layer or two layers can be selected and arranged.

[0029] In one or more embodiments, the filling part 2 and the support part 1 are in an axial symmetry shape. This structure can provide stable and uniform support for both sides of the heel.

[0030] In one or more embodiments, the support part 1 comprises a support upper part and a support lower part, and the filling part is located in the support upper part; the shape of the support upper part is matched with the shape of the filling part. That is, the shape of the support upper part is a radial extension of the shape of the filling part. The support lower part is mainly used for connecting with the shoe, and this part does not need to be provided with the filling part, and the filling part is mainly located in the support upper part.

[0031] In one or more embodiments, the connection part between the support upper part and the support lower part is recessed to the middle to form a waist part.

[0032] In one or more embodiments, the filling part 2 comprises a first wing part 21, a connecting part 22 and a second wing part 23 arranged in sequence, and the filling part is in a W-shaped structure. The first wing part and the second wing part are arranged in a central symmetry along the connecting part. The W-shaped structure formed thereby can provide effective support and avoid collapse.

[0033] The W-shaped multi-peak design decomposes the vertical impact force through multiple support points into transversely extended tension, reducing the damage of instantaneous pressure to the heel. The first wing and the second wing symmetrically wrap the two sides of the heel, forming a "hugging support", reducing the lateral shaking of the heel during movement, and the longitudinal bearing axis can inhibit the excessive deformation of the heel during sudden stop or jumping, reducing the risk of ankle sprain.

[0034] In one or more embodiments, the thickness of the upright cotton 3 of the filling part 2 is 1-2.5 cm. The thickness of the filling part decreases from the middle to the periphery, and the thickness referred to here is the maximum thickness.

[0035] In one or more embodiments, the density of the upright cotton 3 is 100-300 g / m 2 .

[0036] The upright cotton filling with the above thickness and density range can provide sufficient strength and elasticity at the same time, ensuring the support and comfort of wearing.

[0037] In one or more embodiments, the surface of the upright cotton 3 is provided with a hydrophobic coating. By providing a hydrophobic coating on the surface of the upright cotton, the water resistance and durability of the upright cotton can be improved, and the yellowing resistance of the upright cotton can also be improved.

[0038] In one or more embodiments, the hot melt adhesive film is a PES hot melt adhesive film.

[0039] In one or more embodiments, the first fabric and the second fabric are both polyester fabrics. Any commercially available polyester fabric can be used.

[0040] As described above, the upright cotton is a polyester substrate, and PES hot melt adhesive film and polyester have good chemical compatibility, reliable bonding effect, and can effectively avoid the problem of delamination or degumming caused by incompatibility of materials.

[0041] The heel structure is obtained by pressing the first fabric, the first hot melt adhesive film, the upright cotton and the second fabric from top to bottom.
