Active-carbon-containing midsole, insole, particle and preparation method

Abstract

The invention discloses an active-carbon-containing midsole, an insole, a particle and a preparation method. The midsole, the insole and the particle comprise a substrate and a plurality of active carbon particles, wherein the substrate is in a sponge body shape, the active particles are uniformly distributed in the substrate and are respectively positioned in gaps of the sponge body, and pores of the sponge body are conducted to the surface of the substrate. When people walk, the substrate continuously deforms, the pores of the sponge body can be continuously contracted and expanded, so the air in the shoe and the air in the pores of the sponge body can continuously generate convection and replacement, after entering the pores of the sponge body, air with odor molecules in the shoe is subjected to absorption purification through the active carbon particles and then flows into a space in the shoe, the air in the shoe is continuously and effectively purified, a better deodorization effect is realized, the proportion of the active carbon is more than twice higher than the proportion of the active carbon of the ordinary insole, the contact area and the period of the active cabin and the air are respectively and greatly increased and prolonged, the active carbon is in a state of being isolated from the air when the insole is not used, and the service life of the insole is prolonged.

Description

[0001] technical field [0002] The invention relates to a midsole with activated carbon, insoles and granules, and also relates to a method for making the midsole and insole granules. [0003] Background technique [0004] Midsoles and insoles are usually placed inside the soles to increase the comfort of wearing shoes. With the continuous improvement of people's quality of life, midsoles and insoles are required to have more functions. For example, midsoles and insoles are usually required to have removal Odor and treatment of beriberi and other functions. [0005] At the present stage, most of the midsoles and insoles have the function principle of removing peculiar smell by using activated carbon with adsorption function. For example, a patent document with the publication number CN201491833 discloses an insole, which adopts a layered structure, specifically , a layer of activated carbon layer is set between the upper layer and the lower layer, and the upper layer is p...

Problems solved by technology

[0005] At the present stage, most of the midsoles and insoles have the function principle of removing peculiar smell by using activated carbon with adsorption function. For example, a patent document with the publication number CN201491833 discloses an insole, which adopts a layered structure, specifically , a layer of activated carbon layer is set between the upper layer and the lower layer, and the upper layer is provided with air holes. When in use, the adsorption of activated carbon is used to achieve the effect of deodorization. However, when the above insole is in use, the air in the shoe flows Poor performance, and the contact surface between the activated carbon and the air in the shoe is small, which greatly reduces the adsorption capacity of the activated carbon and affects the deodorization effect of the midsole and insole. At the same time, the contact area is small, and the adsorption capacity of the activated carbon around the air holes It tends to reach saturation quickly, making the service life of the midsole and insole shorter

Moreover, at this stage, midsoles and insoles with activated carbon are prone to dust during the production process, and it is difficult to control the cleanliness. When worn, shoes and socks will be dirty, and the activated carbon will lose its function when it meets water, causing the midsole to be dirty. 1. The insole cannot be cleaned, the plasticity of the activated carbon is low, and the top touches the sole of the foot, which is easy to cause discomfort; at the same time, because it takes a long time for the shoes to be worn by consumers after leaving the factory, the activated carbon built in the insole is in direct contact with the air. After a period of time, the adsorption capacity of activated carbon has reached saturation, and when consumers wear it, it is difficult to have the adsorption capacity again
