Embodiment 1

[0032] Such as figure 1 As shown, a kind of insole is provided in the present embodiment, comprises thin layer 100 and thick layer 200 of press-fitted structure, thin layer 100 is made of bamboo charcoal fiber and negative ion fiber, and thick layer 200 is made of 100% pure polyurethane production.

[0033] Such as image 3 As shown, the thin layer 100 and the thick layer 200 are pressed together from top to bottom into an integrated structure, wherein the sole and heel of the thick layer 200 are raised in an arc shape, and the middle of the foot at the junction of the sole and the heel is in a small arc protrusion. The size can be made according to the selection of the mold during molding or post-processing. The shape and area of ​​the thin layer 100 are the same as those of the thick layer 200, which facilitates one-time molding between the two. Of course, it can also be slightly larger or smaller, so that it can be more accurate when cutting the insole.

Embodiment 2

[0043] This embodiment provides a method for making an insole, comprising the following steps:

[0044] A. Molding process, adding non-toxic additives to polyurethane, foaming and injecting into a single mold, after the reaction is finished, take out the formed thick layer from the mold; the insoles made from this are all independently molded, And there is a layer of solidified thin skin on the surface of the insole, which has good hand feeling and excellent physical properties, which can prolong the service life of the insole.

[0045] B. Mixing process, adding textile negative ion additives to the bamboo charcoal fiber masterbatch and stirring evenly, and forming a thin layer after uniform mixing; the amount of negative ions in the formed thin layer is 500-1000 / cm 3 , combined with a specific shoe cavity space, can achieve the best adsorption and purification effect.

[0046] C. pressing process, on the thick layer that forms in step A, press the thin layer that is made of ...

Abstract

The invention discloses an insole and a production method for the same. The insole comprises a thin layer and a thick layer, which are laminated into an integrated structure, wherein the thin layer is made from bamboo carbon fibers and anion fibers; the thin layer is made from polyurethane with purity of 100 percent. According to the technical scheme, foot pressure can be better dispersed, various foot diseases can be avoided, foot health can be ensured, walking time and activities can be increased, and moreover, automatic shaping, fatigue elimination, bacterium removal and purification of the interiors of shoes can also be implemented.

Description

technical field [0001] The invention belongs to the technical field of insoles, and in particular relates to a changeable and washable insole which can be automatically shaped, fatigue-eliminated and sterilized and a manufacturing method thereof. Background technique [0002] When people wear shoes, people's feet are prone to sweating, especially when exercising, so the air humidity in the shoes is high. On the one hand, this causes discomfort in the feet, on the other hand, it is easy to form odors, and walking or exercising in shoes for a long time will also cause heel pain, pain and blisters on the front of the feet. This will lead to difficulty in walking, discomfort on the soles of the feet, and in severe cases may lead to various diseases of the feet such as corns, blisters, and calluses. [0003] Although there are many insoles on the market that have a certain supporting effect, they cannot reduce the pressure on the feet and remove the peculiar smell in the shoes. ...
