Shoes Material

1.     Rubber: various sports shoes sole. Pros: good wear resistance, slip, flexible, easy to break and more flexible, with good extension, contraction, and stability, great hardness, flexural strength. Disadvantages: heavy, easy to spit in the cream (which is a quality problem), and severe corrosion (environmental issues) 2 PU: polyurethane synthetic polymer materials, often with a long basketball, tennis shoes at the end, may be also used for casual shoes at the end. Pros: density, hardness, wear resistance, good flexibility, good resistance to oxidation, corrosive, environmentally friendly, easy to fold. Disadvantages: absorbent, easy to turn yellow, easy to break, the elongation is poor, no water, at the end of the perishable. 3. EVA vinyl acetate copolymers, polymeric material. Commonly used as jogging, walking, casual shoes, sneakers and the end of the foot.

Pros: lightweight, flexible, good flexibility, easy to fold, with excellent color, suitable for all ages. Disadvantages: easy to absorb water and corrosion reaction is not easy, slightly dirty. 4th Phylon (R) is the second high-pressure molded EVA, shoes international racing, tennis shoes, basketball, ultimately, the main ingredient can also be used for casual shoes at the end. Pros: lightweight, flexible, thin appearance, sweetness. Easy to clean, hardness, density, tensile strength, tearing, stretching and good. Cons: not easy to unfavorable environmental corrosion, high temperature, easy to fold, easy to shrink. Fifth TPR: TPR granules with melt after the injection, commonly used for jogging, walking, sports shoes eventually. Advantages: plastic, cheap. Disadvantages: weight, bad wear (no wear), poor flexibility, poor bending (not bending), shock-absorbing capacity of the poor in the sixth

Performance Comparison: TPR in relation to heavy, general flexibility, strength in general. Most of the rubber at the end, but a soft, very portable, a strong hold, but the flexibility is poor, are generally used in indoor soccer shoes and casual shoes. At the end of the EVA is lightweight, flexible, decreases only wear a long, flexible, still feel a bit '. BM, MD at the end of the flexible and resilient, without deformation, flexible and comfortable during exercise, the share of small, very light, so use a larger (PU density is greater than the MD a better shock absorption, but also quite heavy). Movies tend to be large, rubber, wear slip. 7. Price, cheapest TPR, PU = TPR × 2 times, the MD = TPR × 4 times, the pad 4 times × MD = TPR, PU pillow = TPR × 4-6 times.

Cushion MD = TPR × 4 times, cushion PU = TPR × 4-6 times. (B), physical activity and performance of the group described in the upper material: canvas shoes around the PVC, PU, ​​Pakistan, a cow, microfiber, a natural skin, eyes and other categories, the following brief description of each: 1 PVC, most of the cheaper, poor design, not cold, not folding, the products do not make the PVC fabric. 2. PU leather, cattle in Pakistan: the market is the most used material. PU leather is soft, flexible, feel better, smoother surface. Pakistan, most of the opaque surface like cattle, apparently Cuse, and has shown little spray to remove shiny face, most of the inflexible. Livestock in Pakistan, the PU were different, but uses its features. PU proportionally greater use of some of the price data plexus block ten copies of one hundred dollars. Shoes and mid-range cattle of us with Pakistan and PU leather uppers. 3.

3. Microfiber High quality to the texture, the performance is very close to natural skin, but more than the thickness of the natural elasticity of the skin is balanced, is a kind of leather in one of the best materials. The cheapest are 60 yuan per meter, well, up to 200 yuan, now most of the shoes on the use of this material. 4. Natural skin: the material is widely recognized, is breathable, flexible, resistant to chipping, bending, rustic, solid, the disadvantage is imperfect, many pores, irregular shape is not easy to adapt. Leather has always been loved by the people, leather shoes have leather, pigskin suede, ostrich leather, leather carp, snake and many other species. The widespread use of leather shoes. The leather can be divided into the first layer and second layer of skin known as the first layer of rubber balls, the second floor, called the exterior leather or patent leather two, the price is usually the first layer Skin is the second floor of 35 times. Sport shoes, basketball shoes, especially the extensive use of the first layer of skin, great value. 5. Mesh: The three main types, the ingredients of the mesh, the local surface exposed, light and good air permeability, resistance to bending, as sandwich mesh. Accessories Collier, like velvet, the fabric BK, and coating materials, such as stitchbond. Main characteristics of wear resistance, breathing well. 6. Note: shoes, shoe materials are labeled in a shoebox, can be controlled. In addition to the components of footwear: shoes, mainly by the upper layer (lining) before and after the hot end, before and after the header at the end (also called end of inches), and other exclusive parts. CORTE: Cuero general equipment (leather), leather or artificial leather material mixed, the best is probably the first layer of skin, smooth scalability, well, sheepskin shoes soft top still quite fresh. Sport shoes, basketball shoes, especially the extensive use of the first layer of skin, great value. 5.
