Big Recognition Of Sports Shoes And Shoes

A pair of sneakers, which are different from functional sports, have different functional effects. The most important thing is the application of bottom and surface materials.

(1) Sports shoe sole Classification and performance introduction:

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.

    shortcoming It is heavy and easy to spit (quality problems) and is not easy to corrode (environmental problems).

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

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

    Disadvantages: Strong absorbency, yellowing, easy to break, poor elongation, no water resistance, and rot at the bottom.

    EVA: Vinyl acetate copolymer, polymer material. It is commonly used in jogging, slow walking, casual shoes and midsole training.

    Advantage: Light, elastic, flexible, and easy to wrinkle. It has excellent coloring and is suitable for all kinds of climates.

    Disadvantages: It is easy to absorb water and is not easy to corrode.

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

    Advantage: Light, elastic, fine appearance, soft, easy to clean, hardness, density, tensile force, tear, elongation is good.

  Disadvantages: It is not easy to corrode and is environmentally friendly.

  TPR: The TPR pellets are molded by hot melt injection. They are commonly used in jogging, slow walking, casual shoes soles and large bottoms.

  Advantage: Easy to shape and cheap.

   Disadvantages: Material is heavy and wear is poor (not wearable), softness is poor, bending is poor (no folding), shock absorption ability is poor.

  Performance comparison: TPR is much heavier, more elastic, and generally more durable. 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.

On the price, 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) classification and performance introduction of sports shoe upper.

Sports shoes are about fabrics. PVC, PU, Niu Ba, Microfiber, natural skin and mesh fabric are briefly described below.

  PVC: Most of them are cheaper, with poor texture, no cold resistance, no folding resistance, and products without PVC.

    PU leather, Niu Ba: It is the most commonly used material in the market. PU leather soft It is elastic, feels good and has many luster on the 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: It has soft texture, uniform texture and close to natural skin. But it is more uniform and more elastic than natural skin. It is one of the best materials for artificial 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: It is commonly recognized material, it is breathable, soft, peel resistant, folding, cold resistant, durable, shortcomings are flaws, pores and irregular shape, not easy to tailor. 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, which is used in the exposed area, light and 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.
