Problems solved by technology

[0004] However, the insole obtained by this processing method has many disadvantages. First, because the polyurethane material is being foamed and molded, the hardness and air permeability of the top and bottom parts are usually difficult to meet the needs, and need to be cut off, wasting materials. Secondly, the polyurethane material is cut into the shape of the insole, and the remaining materials are difficult to use, which will cause secondary waste, and the cutting precision is low, and the shape of the cutting is limited. Finally, when the polyurethane material is hot-pressed, because the insole is suitable for users The thickness of the foot is different, but the heat pressure is the same, which will lead to uneven hardness of each part of the polyurethane material, and the part with high hardness will seriously affect its air permeability. In addition, the polyurethane material will be made The rebound performance of the

Embodiment 1

[0030] The perfusion-molded breathable sole includes a surface layer 1, a breathable layer 2 and a hot-melt adhesive film 3. Surface layer 1 can be a kind of in cloth layer or leather layer.

[0031] The breathable layer 2 can be a breathable layer 2 made of material A, material B and a catalyst, the material A is polyethylene adipate, polypropylene adipate, polybutylene adipate or polyethylene adipate Material A is one of diethylene glycol esters, and material B is material B of isocyanate. The catalyst is a catalyst composed of amine and glycol. The amine may be triethylenediamine, and the dihydric alcohol may be ethylene glycol, diethylene glycol, 1,4-butanediol or 1,6-hexanediol. And the total density of the air-permeable layer 2 can be 0.16-0.18g / cm3, and the sole and heel of the air-permeable layer 2 are respectively provided with protrusions 21, which can be obtained by adjusting the corresponding positions of the mould.

Abstract

The invention discloses an infusion-molded breathable insole and a manufacturing method thereof. The infusion-molded breathable insole comprises a surface layer, a breathable layer and a hot melt filmwhich are connected in sequence. The surface layer is provided with a plurality of air holes that run through the surface layer, the hot melt film and the breathable layer. The breathable layer may ensure breathability of the insole; the surface layer may contact with the sole of a user, it is better to touch the insole, and the insole is more attractive; the hot melt film helps improve the connection strength for the breathable layer and the surface layer; during forming of the breathable layer, the breathable layer may arrive at the surface of the insole through the surface layer, thus affecting the use of the insole; the hot melt film with high compactness can prevent the above problem. The air holes can ensure that the hot melt film is penetrated; the hot melt film is avoided affecting the breathability of the insole; the breathability of the insole is further improved.

Description

technical field [0001] The invention relates to the field of insole manufacturing, in particular to a breathable insole. Background technique [0002] The insole is one of the commonly used shoe accessories. It is mainly used as a buffer between the sole and the sole of the foot. The air permeability and resilience of the insole are the main performance indicators of the insole. However, materials with good air permeability often have poor resilience. Insufficient performance and poor touch, while materials with good rebound performance basically have no air permeability. In order to solve this problem, at present, insoles on the market usually adopt a two-layer design. The bottom layer is generally made of polyurethane material with better air permeability, and the surface layer is generally made of leather material or cloth material with better touch, so as to take into account air permeability, Resilience and feel. [0003] And the manufacture of this kind of insole, us...
