A pair of sneakers, depending on their sports uses, have different functional effects. The most important thing is the application of bottom and surface materials.

Sole material

The following are the following:

(1) sports

Sole material

Classification and performance introduction:

Rubber: used in various kinds.

Gym shoes

Big bottom.

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).

PU: polymer polyurethane synthetic material, commonly used in basketball, tennis shoes sole, can also be used directly in the sole of casual shoes.

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

Points: strong absorbency, yellowing, easy to break, poor elongation, water resistance, and rotten bottom.

EVA: vinyl acetate copolymer, polymer material.

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

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

Disadvantages: easy to absorb water, not easy to corrode, environmentally friendly and easy to dirty.

PHYLON (MD): it belongs to EVA two high pressure molding products, 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, soft and easy to clean. Hardness, density, tensile force, tear and elongation are good.

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

TPR:TPR pellets after hot melt injection molding, commonly used in jogging, slow steps, casual shoes soles and bottoms.

Advantages: easy to shape and cheap.

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

Performance comparison: 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.

The bottom of PU and MD is elastic, and it does not deform for a long time. When moving, it is more flexible and comfortable, with a small proportion and light weight. Therefore, it is widely used (PU is more powerful than MD, but its damping effect is better, but it is also relatively heavy).

All large negatives are made of rubber, wear resistant and skid resistant.

     

Price

On top, TPR is the cheapest.

PU=TPR x 2 times.

MD=TPR x 3 times.

MD air cushion TPR * 4 times.

PU air cushion TPR * 4 - 6 times more

    

(two) sports

Shoe upper

Classification and performance introduction:

The material of sports shoes is about PVC, PU, Niu Ba, microfiber, natural skin, mesh cloth and so on.

PVC: most are cheaper, with poor texture, no cold resistance, no folding resistance, and products without PVC as fabrics.

PU leather and Niu Ba are the most commonly used materials 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.

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 for synthetic leather.

The cheapest price is more than 60 yuan per yard, and the price is as high as 200 yuan. At present, most of our shoe models use this material.

Natural skin: widely recognized material, it is breathable, soft, resistant to peeling, folding, and cold. It is durable. It has defects, many pores and irregular shape.

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

Sports shoes are usually made of cowhide.

The cowhide can also be divided into two kinds of skin: the first layer and the skin. The first layer is also called the pearl skin. The two layer is called two skin or lacquer. The price of the top layer is 3 to 5 times of the two skin.

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

Mesh cloth: it can be divided into three main categories. The main material mesh cloth is used in the surface of the side, which 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.

Note: exercise

Sole material

The shoe upper is marked on the shoebox, which can be compared.

The greater the weight of clothing materials, the stronger the pressure on the body, the more uncomfortable the body feels.

In recent years, new materials have been emerging. New fabrics and thermal insulation materials are improving the warmth retention property. At the same time, the weight of materials has also been greatly reduced, making the clothing more comfortable and comfortable. People are more convenient, flexible and free when they are engaged in all kinds of production and life.

Present Situation And Future Innovation Of Neoprene Adhesive

Neoprene adhesive has been widely used in solvent rubber adhesives since its advent in the 50s of last century. It only slowed down after 80s. The reason is the toxicity and flammability of solvents. People are worried about the harm and safety of adhesives. In some developing countries such as China, neoprene adhesive was not available until July 2002.
