Classification And Performance Introduction Of Sports Shoes Making Materials

Classification and performance introduction of sports shoes making materials

First,

Classification and performance introduction of base materials

(1) rubber: used for sole of all kinds of sports shoes; advantages: good abrasion resistance, skid resistance, elasticity, no breakage, good softness, good elongation, stable shrinkage, good hardness and good bending property.

Disadvantages: heavy weight, easy to spit cream (quality problems), not easy to corrode (environmental problems).

(2) PU: polymer polyurethane

It can be used directly in the sole of basketball or tennis shoes.

Advantages: high density, high hardness, good abrasion resistance, good elasticity, good oxidation resistance, easy corrosion and environmental protection, and easy to wrinkle.

Disadvantages: strong water absorption, Yi Bianhuang, easy to fracture, poor elongation, water resistance, bottom rot.

(3) EVA: vinyl acetate copolymer, polymer material.

It is commonly used in jogging, slow walking, casual shoes and midsole training.

Advantages: light weight, good elasticity, good flexibility, non wrinkling, excellent coloring and suitable for all kinds of climates.

Disadvantages: easy to absorb water, not easy to corrode, unfavorable environmental protection, easy to dirty.

(4) PHYLON (MD): it is EVA's two high pressure molding product, and the main material for running shoes, tennis shoes and basketball shoes in the middle of the world, can also be used for soles of casual shoes.

Advantages: lightweight, elastic, fine appearance and soft.

Easy to clean, hardness, density, tensile force, tear and elongation.

Disadvantages: it is not easy to corrode and is environmentally friendly. It is easy to wrinkle and shrink easily at high temperature.

(5) TPR: hot melt molding with TPR pellets, commonly used in jogging, slow walking, casual shoes soles and outsole.

Advantages: easy molding and low price.

Disadvantages: heavy material, poor wear (non abrasion), poor softness, poor bending property (no bending resistance) and poor shock absorption capability.

(6) performance contrast: TPR ratio is heavy, heavy, elastic general, wear resistance is general.

The proportion of rubber base is larger, but it is more soft and wearable. Its grip is strong, but its elasticity is poor. It is commonly used in indoor football shoes and casual shoes.

The bottom of EVA is light and elastic. It only wears a long time to reduce elasticity and become more practical.

PU, MD bottom elastic and long non deformation, flexible and comfortable movement, small proportion, very light, so the use of a wider (PU than MD density greater damping effect is better, but also relatively heavier), the general large plate is used rubber, wear resistant and antiskid.

(7) on the price, TPR is the cheapest, PU=TPR x 2 times, MD=TPR * 4 times, MD air cushion =TPR x 4 times, PU air cushion =TPR * 4 - 6 times.

Two. Classification and performance introduction of sports shoe upper.

Sneakers

There are about PVC, PU, Niu Ba, microfiber, natural skin, mesh cloth and so on.

(1) PVC: most of them are cheaper, with poor texture, no cold resistance, no folding resistance, and products without PVC as fabrics.

(2) PU leather / Niu Ba: it is the most commonly used material in the market.

PU leather is soft, elastic, feels good and has many luster on its surface.

The surface of the Niba is mostly frosted, rough and shiny, shiny and dull, and most of them are inelastic.

Although cattle and PU are different, they have their own characteristics.

Relatively speaking, PU is more widely used, ranging from a dozen to a hundred blocks.

Sports shoes use uppers and PU leather to make vamp.

(3) microfiber: soft texture, uniform texture, close to natural skin, but even more uniform and elastic than natural skin. It is one of the best materials in synthetic leather.

At present, most shoe models use this material.

(4) natural skin: widely recognized materials, it is breathable, soft, resistant to peeling, folding, and cold. It is durable and has defects, many pores and irregular shape.

Natural skin has always been popular among the people; leather for shoes is made of cow hide, pig skin, deer skin, ostrich skin, carp skin, snake skin and so on.

Sports shoes are usually made of cowhide.

The cow skin can be divided into two kinds of skin and the first layer of leather. The first layer is also called the pearl skin, and the two layer is called two skin or lacquer. The price of the top layer is 35 times that of the two skin.

Sports shoes, especially basketball shoes, are of great value in using large layers of cowhide.

(5) mesh cloth: it is mainly divided into three main categories, the main material mesh cloth is used in the exposed side, it is lightweight and has good air permeability and bending resistance, such as sandwich mesh cloth.

Neckline accessories, such as velvet, BK cloth, and linbu excipients, such as Li Xin bu.

The main features are abrasion resistance and good air permeability.

(6) sports shoe sole and shoe upper are marked on shoe boxes, which can be compared.

Besides, the shoes are made up of shoes, lining, lining, back and forth, Baotou, middle bottom (also called inch bottom), soles and so on.

Noodles: materials are generally available.

(LEATHER) or artificial leather, leather material is uneven, the best is the first layer of dermis, soft texture, good scalability.

There are many kinds of artificial leather. The most I touch is PU leather. The thickness is made of silk. Generally, it is made of 80 silk. Good can reach 140 silk. It is suitable for producing a single layer of flour.

Today's most popular PU leather has rubbing leather, leather, froth, crazy horse, size, Napa, 18 lines, and so on.

Soles are an important part of shoes. They have PU bottom, TPR bottom, PVC bottom and combined bottom.
