Novel breathable-insole manufacturing process

Abstract

The invention discloses a novel breathable-insole manufacturing process. The novel breathable-insole manufacturing process includes: performing primary foaming and shaping of a raw material into test pieces; sectioning the test pieces into thickness as required according to different shoe types; gluing off the sectioned test pieces for cloth laminating; performing secondary hot press molding on the test pieces laminated with cloth prior to cutting. The test pieces foamed and shaped are of regular shapes even in thickness; during sectioning the test pieces in the step b, the test pieces are sectioned along the direction perpendicular to the thickness of the test pieces, breathable surfaces of the test pieces are preserved, and unventilated surfaces of the test pieces are removed; sectioning of two surfaces or maybe one surface of the test pieces can meet the required thickness, and the breathable surfaces are preserved; flow production is allowed, demand on density of the foamed material is reduced, working efficiency is high, and cost is lowered; breathable insoles manufactured with the process are high in elasticity, good in flexibleness, lightweight and durable and attractive.

Description

【Technical field】 [0001] The invention relates to a manufacturing process of a novel breathable insole, which belongs to the technical field of shoe sole processing. 【Background technique】 [0002] Existing footbeds or insoles generally include fabrics and foam structures. The traditional method of making such footbeds or insoles is an airtight combination of products, that is, to bond cloth or leather fabrics and foams together. In the production method, foaming, bonding, and pressing are formed in one process, and the foaming raw material is foamed to fill holes, so that the surface of the insole / sole has no air holes, and the airtightness is not easy to absorb water and perspiration; and, in the traditional method, foam molding is a One mold for each model, and shaped foam will cause irregular fluidity of the foam material. At the same time, due to different thicknesses, the hardness of the insole / sole will be uneven, such as the hard forefoot or heel, making it uncomfort...

[0002] Existing footbeds or insoles generally include fabrics and foam structures. The traditional method of making such footbeds or insoles is an airtight combination of products, that is, to bond cloth or leather fabrics and foams together. In the production method, foaming, bonding, and pressing are formed in one process, and the foaming raw material is foamed to fill holes, so that the surface of the insole / sole has no air holes, and the airtightness is not easy to absorb water and perspiration; and, in the traditional method, foam molding is a One mold for each model, shaped foam will cause irregular fluidity of the foam material, and at the same time, due to different thicknesses, the hardness of the insole / sole will be uneven, such as the hard forefoot or heel, making it uncomfortable to wear

On the other hand, the traditional method has strict requirements on the density of the foamed material, because one-time molding, shaped foaming, if the density of the foamed material is low, it will cause material shortage due to the irregularity of the flow

[0003] Generally speaking, the traditional production method requires a large number of workers, the production cycle is not fixed, the work efficiency is low, the insoles produced are heavy, poor in ventilation, poor in comfort, poor in elasticity, unstable in product properties, and difficult to control
