Shock-absorption and breathable insoles and manufacturing method thereof

Abstract

The invention provides shock-absorption and breathable insoles and a manufacturing method thereof. Each insole body comprises a lower sole and a face sole, irregular protrusions are uniformly distributed on the lower surface of each face sole, binder is arranged on the lower surface of each face sole and permeates into all the irregular protrusions, each face sole and the corresponding lower soleare firmly bonded through the binder, all the heights of the protrusions are inconsistent, and breathable channels leading to the peripheral sides of the insole bodies are formed among all the protrusions. The manufacturing method of the shock-absorption and breathable insoles comprises the steps of manufacturing the face soles and compounding the face soles to large soles. The step of manufacturing the face soles comprises the procedures of 1, covering the surface of each shoe material granular material with a glue layer; 2, putting raw material granules of which the surfaces are provided with the glue layers into a mold cavity of a shaping mold to form face sole sheet materials of which two surfaces are provided with the irregular protrusions; 3, cutting each face sole sheet material ofwhich the two surfaces are provided with the irregular protrusions into two sheet materials through an elastic sheet material cutting and forming machine.

Description

technical field [0001] The invention relates to the technical field of insoles, in particular to a shock-absorbing and breathable insole and a manufacturing method thereof. Background technique [0002] The insoles currently on the market generally include the insole body and the fiber fabric layer arranged on the surface of the insole body. When the insole is worn, the fiber fabric layer has little friction with the human foot, and the front palm of the person tends to slide forward when wearing it, which is very uncomfortable. , does not fit well with the feet. In addition, the known insole body adopts a solid structure, and generally uses the material directly to cushion the shock according to the physical properties of EVA itself, but is limited by the performance of the material itself, and has a compression limit and rebound after being impacted by the sole of the foot. The limit cannot respond quickly, and after a period of use, the material ages and collapses, which...

[0002] The insoles currently on the market generally include the insole body and the fiber fabric layer arranged on the surface of the insole body. When the insole is worn, the fiber fabric layer has little friction with the human foot, and the front palm of the person tends to slide forward when wearing it, which is very uncomfortable. , does not fit well with the feet

In addition, the known insole body adopts a solid structure, and generally uses the material directly to cushion the shock according to the physical properties of EVA itself, but is limited by the performance of the material itself, and has a compression limit and rebound after being impacted by the sole of the foot. The limit cannot respond quickly, and after a period of use, the material ages and collapses, which cannot play the role of cushioning and shock absorption; the insole has poor air permeability, which may easily cause the soles of the user to sweat

Furthermore, the air permeability of the above-mentioned insole is generally achieved by punching holes, which not only affects the appearance but also reduces the overall quality of the insole body.
