Background
The insole is widely applied to shoe making industry, health care and special functions; generally divided into two modes of shoe industry application type/shoe factory application type insoles and market commodity type. The insole applied in the shoe making industry is mainly matched with a shoe outsole and a shoe midsole to make a corresponding body; and manufacturing a size plate according to the last bottom plate or the last panel, and manufacturing a corresponding shape. The market commodity type insole is a product which is designed by developers and circulated in the market and is mainly sold as a commodity.
The high resilience insole is a method for distinguishing materials according to the attributes of the insole, so the name is. The high-resilience insole is generally characterized by highlighting the material of the insole, is used together with shoes or used as a selling point, and is defined as a material which can be bounced back immediately after being pressed down by hand; if it is stated at a later point, the crush deformation ratios are also included: namely extruding tens of thousands of times or hundreds of thousands of times to see the deformation rate of the product. High rebound is a proper term in the polyurethane industry, and the object surface with high rebound is slow rebound and cannot be called low rebound. These two properties are a criterion for dividing the properties of a material, and are called as such. Therefore, the attribute of the insole can be more visually described, and the characteristics of the insole are summarized.
Although the shoe-pad form variety on the existing market is more, the selectivity is also comparatively abundant, however because the shoe-pad that uses at present, traditional integral type bonding installation is still taken mostly to ventilative screen cloth on its shoe-pad body, in long-term use, especially in a large amount of motion with scrub very easily take place to drop, lead to the shoe-pad body to have the bottom only, it is comparatively uncomfortable to wear, and the shoe-pad is in the dress, the wearing and tearing that heel and sole position caused are great, the shoe-pad is in effective life-span, because the wearing and tearing of heel and sole, cause aesthetic measure and the coefficient of friction reduction of shoe-pad, make people have to change the shoe-pad, cause a large amount of wastes, traditional shoe-pad resilience is lower simultaneously, in use is harder, the comfort is relatively poor.
Therefore, it is necessary to provide a new ultra-high resilient insole and a preparation process thereof to solve the above technical problems.
