Problems solved by technology

Polyester fiber has excellent high strength, wear resistance and dimensional stability, but its moisture absorption rate is low, sweating is easy to slip, antibacterial and deodorant are poor, etc. Therefore, the composite insole made of polyester fiber weakens the comfort of the insole to a certain extent performance

Abstract

The invention discloses a composite insole with a gradient function and a making method thereof. The composite insole is made by compositing a modified EVA foamed insole with an insole cloth, wherein the modified EVA foamed insole is made of a plant fiber powder-modified EVA composite foamed material. The plant fiber powder-modified EVA composite foamed material is prepared through a method comprising the following steps that plant fiber powder is modified by a silane coupling agent; an ethylene-ethenyl ethanoate copolymer and the modified plant fiber powder are mixed and then blended; a foaming agent, a cross-linking agent and a foaming aid are added into the blended system to continue to be blended; the blended materials are pressed into a sheet; a release agent is sprayed to a mold of a foaming machine, the sheet is added into the mold for mold pressing foaming, and then the plant fiber powder-modified EVA composite foamed material is obtained. The insole cloth is a blended cloth of blast fiber and chemical fibers. According to the composite insole and the making method thereof, the processed hemp stem core powder is added into the EVA foamed insole, therefore, a gradient from functions to mechanical properties is formed, and the wearing requirements of sports shoes and boots, functional training shoes, leather shoes and the like are effectively met.

Description

technical field [0001] The invention relates to an insole and a preparation method thereof, in particular to a composite insole with gradient function and a preparation method thereof. Background technique [0002] The insole of sports shoes is usually made of foam material and insole cloth. Foaming materials are mostly EVA foaming materials or polyurethane foaming materials, which have certain elasticity and cushioning properties, and play a role in cushioning the feet during exercise, but the insoles made of these foaming materials have poor durability and resilience , There is no good tear resistance, which affects the wearing effect. At the same time, poor moisture absorption and quick-drying properties, lack of antibacterial and deodorant properties, greatly reduce the wearing comfort. [0003] Composite insole fabrics are mostly made of polyester fiber materials. Polyester fiber has excellent high strength, wear resistance and dimensional stability, but its moisture...
