A warp knitting spacer fabric composite sole

Abstract

The invention relates to a warp knitting spacer fabric composite sole. A production method of the sole is characterized by performing, with general polyester monofilaments and high-tenacity polyester monofilaments as raw materials, warp knitting by using a two-needle bar warp knitting machine based on a three-dimensional screen cloth warp knitting method to prepare elastic screen cloth through warping, warp knitting and after-finishing. Based on the method of three-dimensional warp knitting of warp knitting spacer fabric characterized by integral forming, a sole has excellent structural strength, elasticity and light weight; the warp knitting spacer fabric composite sole has excellent moisture conductivity and breathability performance of three-dimensional fabric; the polyester filaments with an antibacterial function and high tenacity are used as the screen cloth materials for the sole, so that the sole has the functions of bacteria resistance and bacteriostasis; a multi-step chain extension and tackifying process can be performed by using a tackifying chain extender with epoxy functional groups, so that the problems that conventional powdery tackifying is low in efficiency and micro-molecules are hard to remove in a tackifying process are solved. The prepared warp knitting spacer fabric composite sole has a broad application prospect in the field of shoe materials.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a warp-knitted spacer fabric composite shoe sole. Background technique [0002] There are many types of sole materials, which can be divided into natural base materials and synthetic base materials. Natural bottom materials include natural bottom leather, bamboo, wood, etc., and synthetic bottom materials include rubber, plastic, rubber-plastic composite materials, recycled leather, elastic cardboard, etc. However, in order to improve the properties of elasticity, moisture absorption and breathability, the current materials for shoe soles are prepared by foaming solid materials, the prepared pores are difficult to control, and the uniformity is poor; and a certain forming mold is required for reverse molding production, resulting in low production efficiency. Especially because the bonding of the sole and the upper material requires the use of adhesives, etc., causing...

Problems solved by technology

However, in order to improve the properties of elasticity, moisture absorption and breathability, the current materials for shoe soles are prepared by foaming solid materials, the prepared pores are difficult to control, and the uniformity is poor; and a certain forming mold is required for reverse molding production, resulting in low production efficiency. Especially because the bonding of the sole and the upper material requires the use of adhesives, etc., causing a large number of environmental protection problems and bringing a large amount of environmental pollution to the enterprise; and the new environmental protection sole material is firstly environmentally friendly, and secondly has a certain degree of elasticity and is also environmentally friendly. Need to have a certain degree of ventilation, but also hope to have the characteristics of light weight
