Advantages: easy shaping, cheap;
Disadvantages: Material weight, wear bad (not wear), poor flexibility, poor bending (not folding) , shock-absorbing ability is poor.
performance comparison:
TPR than major, more heavy, general flexibility, durability general. A larger proportion of rubber at the end, but more soft, very wear-resistant, strong grip, but the flexibility is poor, usually used in indoor soccer shoes and casual shoes.
EVA bottom is light, flexible, flexibility is reduced to wear for a long time, become practical point. PU, MD at the end of flexible and durable without distortion, more flexible and comfortable during exercise, the proportion of small, very light, so the use of more extensive, (PU MD density greater than the better shock absorption, but also relatively heavy). Rubber film are generally large, wear non-slip.
price –
TPR cheapest
PU = TPR × 2 times
MD = TPR × 3 times
MD cushion TPR × 4 times
PU cushion TPR × 4-6 times
(b) upper material classification exercise the first volume and performance:
fabric shoes about PVC, PU, ??cow Pakistan, ultra-fine fibers, natural leather, mesh and other categories, the following were outlined:
< br /> PVC: most of the more expensive, poor texture, cold intolerance, not folding; products made without PVC fabric.
PU leather, cattle Pakistan: the market is the most widely used material. PU leather is soft, flexible, feel better, have more surface
Microfiber: texture soft, even texture, the performance is very close to natural skin, but more uniform than natural skin thickness, elasticity is more balanced, is leather class is one of the best materials. The cheapest prices are more than 60 yuan per yard, good up to 200 yuan, at present most of our shoes based on the use of this material.
natural skin: the material is widely recognized, it is breathable, soft, resistant to peeling, folding, cold-resistant, durable, disadvantage is flawed, the pores more irregular shape is not easy tailoring. Natural skin has always been loved by the people; leather shoes have leather, pigskin, deerskin, ostrich skin, crocodile skin, snake skin and so are many. General use of leather shoes. Leather can be divided into the first layer and second layer of skin, known as the first layer of dough beads, two-story called two split leather or patent leather, the price is generally the first layer of skin is the second floor of 3-5 times. Sports shoes, basketball shoes, especially the extensive use of first layer of leather, of great value.
mesh: three main types, ingredient mesh, with the exposed parts of the uppers, lightweight and with good air permeability, resistance to bending, such as sandwich mesh; collar accessories, such as velvet , BK cloth; also in cloth accessories, such as Li new cloth. Main features of wear-resistant, breathable good.
Note: sports shoe materials, shoe materials are marked on the shoe box, you can control.
gloss. Cattle Pakistan mostly matte-like surface, feel Cuse, and showed little shiny face mist elimination, most inelastic. Cattle Pakistan, PU were different, but to use their own characteristics. PU with relatively broader, the price from ten to a few hundred block range. Shoes with mid-range cattle over Pakistan and PU leather uppers do.
in the end
1, are shoes in the end I think I do not say many people will know that PHYLON in the end, the most common and EVA midsole. In the end are really two kinds of species do not belong to the same property that (plastic type), but why have a name for the different? PHYLON originated in the United States, the first shoe in the end are called PHYLON, no EVA midsole and PHYLON in the bottom of the points, then continue with the development of footwear products to Taiwan and South Korea, some of the big brand footwear research and development facility for the source, the name of the end points in a more systematic, there we are talking about EVA midsole. Next? ** Yi Tang Yi, Tuen ㄋ VA is in the vertebral end and PHYLON in the end the difference between.
shoes in the end is now the most widely used is PHYLON in the end, PHYLON biggest feature is the lightweight, flexible, and has good cushioning properties, PHYLON called secondary foam. EVA midsole is also very light, but the cushioning and flexibility in far less than the PHYLON in the end, the cost is much lower than the PHYLON, EVA foam midsole is called once. The reason they attribute the same, but different names, different performance PHYLON is the second reason is that foam, EVA is a foam.
(1) a foam: the material after injection into the mold heated to high temperatures by forming the shoes in the end, called a foam midsole, which is the EVA shoe midsole.
(2) secondary foam: the material injected into the mold, heated to high temperatures to burn through two molded shoes in the end, it is called the secondary foam in the end, that is, We often say PHYLON in the end. PHYLON and softness is controlled by temperature, in the process of firing PHYLON in the end, the higher the temperature, the density of PHYLON burn out the greater, more hard. Smaller the natural heat burning out of PHYLON the more light the more soft, so the evaluation of shoes in the end good or bad by weight or measure of the degree of soft and hard.
(3) cloth burned in the end: the end of burning cloth is PHYLON in the end, but the designer in order to pursue the overall sense of design and technology with a shoe, the best example that is, the shoes and the shoe body with the end of the same kind of fabric, making the whole body of the shoe sole and the combination of this shoe *** is a bright spot on. This process is achieved by selecting the fabric bag is formed of PHYLON in the end, in the mold in the high temperature burning, becomes, as we see LB1 texture of cloth shoes in the end.
2, PU midsole: In addition to PHYLON in the bottom and EVA midsole, PU midsole is also very common, PU upper hand in the end is the greatest flexibility and toughness.
3, end of the package: Now a lot of shoes with built-in bottom structure, also called the end of the package. Like the familiar T-MAC series, NIKE family belong to the wind sent the end of the package structure, the end of the package from the appearance of the outsole and upper of two major components, but the structure still has the outsole, midsole and shoes surface of three parts, but in the end package in the upper inside.
insole and integral sole
1, in the end: the end of the package can also be done at the end of the acid form, and the end of the package is different, in end of the structure is wrapped in a large shoe hysterical at the end, for example FORCE1, even within the bottom structure, rather than the overall appearance of the watch as rubber outsole, rubber outsole is at the inside of the package have shoes in the end , this is also called in the bottom end of the MD, EVA is a foam one.
2, the overall style sole:
(1) integral EVA soles are the most common foam molding soles, this shoe capital base, and degree and non-slip poor, the sole touches the water, like after like wearing roller skates. REEBOK is this EVA soles of 3D foam molding of the sole best “voice.”
(3) PU soles whole: ADI and NIKE to use this time not a lot of soles, PU soles of the shoes are low-temperature molding. PU is characterized by the end of the light, but not wet, hit the water after a chemical reaction and corrosion away layer by layer.
(4) pure rubber soles: pure rubber soles for outdoor hiking shoes or work shoes, electrical shoes. Throughout the whole letter soles of rubber composition, the advantages of wear-resistant non-slip, drawback is that too much weight. CAT work shoes with the soles generally, also known to make edge soles.
PU: polyurethane polymer composition.
advantages are: density, high hardness, wear resistance, good flexibility, good resistance to oxidation, corrosive environmentally friendly, easy to fold;
weaknesses are: water absorption , easy to yellowing, easy to break, elongation is poor, not water, at the end of perishable.
PHYLON: EVA secondary high-pressure molding.
advantages are: lightweight, flexible Well, the appearance of fine, good softness. easy cleaning, hardness, density, tensile, tear, elongation good.
disadvantage: difficult to adverse environmental corrosion, high temperature, easy to fold easy to shrink.
sole materials on the market today there are PU, PVC, NR, BR, SBR, etc., for the sole clean room material EVA, PU and PVC. This simple first volume of the clean room of several commonly used sole materials.
sole materials on the market today there are PU, PVC, NR, BR, SBR, etc., and clean room commonly used sole materials: EVA, PU and PVC. Following on the first volume to look at these types of simple sole material.
(1) EVA midsole: ethylene – vinyl acetate copolymer referred to as EVA, compared with polyethylene, EVA due to the introduction of the molecular chain of vinyl acetate monomer, thereby reducing the high crystallinity, progress of the flexibility, impact resistance, heat sealing filler compatibility and performance. EVA midsole EVA refers to after injection into the mold heated at high temperature after forming the shoes in the end, also called a foam midsole. EVA is the traditional hot, EVA EVA injection molding machine to mold particles directly inside fired into the machine, vacuum sulfur about 400 seconds after the mold open, in-mold foam molding soles, and then through heat, cold setting box shape. This method most important feature is the high yield, a molding. drawback is easily deformed, yellow over time, shrink.
(2) PHYLON in the end:
PHYLON originated in the United States, the first shoe in the end are called PHYLON. Refers to the material injected into the mold, heated to high temperatures to burn through two molded shoes in the end. Used for sports shoes. PHYLON and softness is controlled by temperature, in the process of firing PHYLON in the end, the higher the temperature, the density of PHYLON burn out the greater, more hard. Smaller the natural heat burning out of PHYLON the more light the more soft, so the evaluation of shoes in the end good or bad by weight or measure of the degree of soft and hard.
(3) cloth burned in the end: the end of burning cloth is PHYLON in the end, is in pursuit of the overall sense of design and technology with a shoe, the best example is shoes in the body of the shoe bottom and use the same kind of cloth, shoes, body and sole to achieve the overall combination. This process is achieved by selecting the fabric bag is formed of PHYLON in the end, high-temperature firing in the mold forming.
(4) PVC Midsole: PVC is polyvinyl chloride, is a kind of leather, was the first invention of substitutes for leather fabric. Is to use PVC plasticizers and other additives rolling the cloth made of composite. PVC impact strength, low thermal deformation, and elasticity as PU.
(5) PU midsole: In addition to PHYLON in the bottom and EVA midsole, PU midsole is also very common. PU name for polyurethane, is often used in the hands after the end of dissection based on the large density of durable foam rubber materials play a damping role. PU midsole for maximum flexibility and toughness, the upper hand is better.
(6) package in the end: end of the package from the appearance of the outsole and upper of two major components, but the structure or the outsole, midsole and upper three parts, but to the end of the package in the upper inside.
(7) PU whole sole: PU shoe soles are low-temperature molding. PU is characterized by the end of the light, but not wet, hit the water after a chemical reaction and corrosion layers away.

all man-made fiber products are particularly afraid of fire, is confronted with soot, Mars and other easy to form holes, if born in the north, and with fire, decisive without fiber . Cotton comfortable, easily the best choice for allergy physical texture of cotton, to buy cotton underwear decisive. But cotton wrinkle easily, pretty, cotton plus polyester in addition to feel better, wear comfortable, and easy to fold feature, which is the best choice for age, coat, of course, do better if breathable polyester, is also a good summer choice.
Jin perish: the nylon, the strongest wear resistance, good moisture absorption than polyester, but poor flexibility, easy to fold, heat resistance and light resistance are poor. Down jackets, mountaineering clothing the best choice, socks are often used.
Polyester: anti-crease, flexible, easily deformed, easy to dry, good lightfastness, acid, alkali extent of their damage is not great, not afraid of mold infestation. Abrasion resistance than nylon, less hygroscopic, wearing a hot feeling, easy to carry static electricity, dust contamination. A thermoplastic, it can be done pleated skirts, pleated lasting.
Acrylic: commonly known as fake fur, Paul is not in hot wool fabrics under the light of a variety of fabric is the first, less hygroscopic, easily stained, worn with a sense of stuffiness.
acrylic / rayon gabardine: nitrile, 50% of each sticky, thick tight, strong and durable, but poor flexibility, easy to wrinkle.
acrylic / viscose women do: 85% acrylic and 15% viscose, luster bright, light, durable, elastic difference.
acrylic / polyester tweed: acrylic, 40% polyester and 60% each, very flat appearance, fastness iron, comfort is poor.
spandex: often used in the elastic part of the clothing, with added spandex in general have flexibility. Content is often less than 10%.

to say in English SWEATER, in some coastal cities, older people know the name – is a thick knitted clothes, long sleeve sports and leisure fir, long-sleeve material is generally thicker than normal. Tight elastic cuffs, side and cuffs under the clothes, the material is the same.
[History] sweater
few able to combine fashion apparel category and function, but the sweater is an exception. As the integration of comfort and style, sweater, sports of all ages who have become the preferred equipment.
“sweater” was born in New York in the 1930s, was the production of tooling for the cold storage workers. However, comfortable sweater, and the characteristics of heat gradually by athletes of all ages, soon after his girlfriend is popular in the football player and star in music.
to 70 years, Hip-Hop culture began to rise. Sweater has become a symbol of rebellious sub-culture, young people wear a hat that cover the face, while his soul and can do across the world.
Hip-Hop culture in the late 1990s as popular culture can not be low in an effort, TommyHilfiger and Ralph
Lauren and other designers began to launch their own brands in the printed Logo of the University of sweater products, followed by Gucci and Versace these high-fashion brands will also be added to the product line sweater.
Vogue writer Sarah
Harris to “sweater” as “a restless boy,” but appeared in Vogue in the office have been docile sweater a lot, elegant and simple, beautiful fabrics.
Today, all of the brands are all kinds of styles and patterns in the launch of the sweater, sweater can not find the shopping mall or store the product has to do track.
sweater gradually kill the rebellious temperament and turn into a public fashion, but it is rare for a unique and driven by the constant pursuit of offering a limited number of artists and photographers? ** casein rope  Gan Metaplexis stauntoni Kariya ⅰ? br / <

sole identification of the materials and features:
on PU, PVC, TPR, RUBBER and other identification!
PU is the lightest and most resistant grinding and of course the price is the most expensive.
PU sole material is easy to recognize, very light in his hand, soles of the holes are round the back.
The soles of PVC material in his hand than to be re-TPR.
TPR material is better than PVC flexible soles, the soles of the holding firm, the next to fall naturally, if it can bounce TPR is the
PVC material than the TPR soles to be cheap, but quality is not good, especially in the winter, it is easy off the bottom.
PVC material has a sole feature is no injection hole, as well as with the smell, then taste. stood for a long time, then still president of the white stuff.
TR soles surface is bright. than the average TPR soles to be stiffer. TR injection hole of more than TPR of injection holes is very special.
weight: RUBBER (rubber) most important, PU, ??EVA lightest,
material: PU expensive, EVA, TPR moderate, PVC cheapest,
craft: TPR is to do it a shape, and to process PVC, ABS materials are generally high heels, expensive and hard,
applications: PVC is used in lining or bear the weight of the parts, or making children shoes ; PU leather for shoes can withstand the weight of the fabric or the site. In the bag, the more applicable is the PVC leather. This is due to different items in the bag to wear in the shoes of the feet, will not emit heat; do not bear the weight of the individual.
PU, PVC way more easy to distinguish, from the corner to see the end of PU PVC fabric thicker than many also feel there are differences, PU soft to the touch of some; PVC feel hard some; also you can use fire to burn, PU PVC taste than the taste of a lot to light.
Appendix I:
1, natural rubber, natural rubber
mainly from Hevea, when the rubber trees are cut when the skin , is drawn from the milky sap, called latex, latex by the pool, washing, molding, drying derived natural rubber.
synthetic rubber by synthetic methods and obtained using different raw materials (monomers) can be synthesized different types of rubber.
2, general rubber
is the place of some or all types of plastic used in natural rubber such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, mainly used for the manufacture of tires and general rubber products industry. Universal rubber demand is the main varieties of synthetic rubber.
SBR:
styrene butadiene rubber and styrene butadiene copolymer is obtained, is the most common synthetic rubber production, there SBR , SSBR and thermoplastic rubber (SBS).
butadiene rubber:
butadiene is obtained by solution polymerization, butadiene rubber is exceptionally good resistance to cold, abrasion resistance and flexibility, but also has more good anti-aging properties. Butadiene rubber used to make most of the production of tires, a small number of products for the manufacture of cold-resistant, cushioning materials and tape, rubber shoes and so on. Butadiene rubber cross drawback is tear resistance, good anti-slippery properties.
isoprene rubber:
isoprene rubber, polyisoprene rubber is referred to, by solution polymerization legitimate production. Isoprene rubber and natural rubber, like, has good flexibility and abrasion resistance, excellent heat resistance and good chemical stability. Isoprene rubber, raw rubber (raw ago) intensity was significantly lower than natural rubber, but the uniformity of quality, processing performance, and other than natural rubber. Isoprene rubber can replace natural rubber truck tires and off-road tires can also be used in the production of various rubber products.
isopropyl rubber:
ethylene-propylene rubber, ethylene and propylene as the main raw material synthesis, anti-aging, electrical properties and resistance to ozone every edge performance outstanding. EPDM can be filled with a large number of oil-filled and carbon black products, lower prices, ethylene-propylene rubber, chemical stability, wear resistance, flexibility, oil resistance, and styrene butadiene rubber close. EPDM wide range of uses, as the tire sidewall, strips and tubes and automotive parts, also can be used for wire and cable wrapping, and high-pressure, high pressure materials to make edge. Also manufacture shoes, hygiene products and other light products.
neoprene:
It is based on chloroprene as the main raw material, the other by a small amount of homopolymer or copolymer formed. Such as high tensile strength, heat resistance, light resistance, good aging resistance, oil resistance are superior to natural rubber, styrene-butadiene rubber, butadiene rubber. With a strong flame resistance and excellent resistance to extended-flammable, and its high chemical stability, good water resistance. Neoprene is the power to make the shortcomings of edge properties, resistance to cold performance is poor, unstable during storage of raw rubber. Neoprene widely used, such as used to make the transport belt and drive belts, wires, cables foreskin material, manufacturing oil hoses, gaskets and corrosion-resistant chemical equipment lining.

first explain the sole Several acronyms mean material (material for the sole explanation based) MD, EVA
1. First to say what is MD: MODEL or PHYLON dragon collectively
2. So what is PHYLON: (commonly known as dragon) is a shoe made sole material is generally used in the end,
with heated compressed EVA foam made from a mixture of substances (which is the second high-pressure molded EVA) features light weight, flexibility and good seismic performance, hardness is controlled by the foaming temperature.
3. So what is the EVA: EthyleneVinyl
Acetate-vinyl acetate. lightweight, flexible synthetic material. So: MD soles which must contain EVA, MD, also known as PHYLON bottom end. Such as MD = EVA RB or EVA RB TPR and some shoes RB PU and so on. ,
RB, PU, ??PVC, TPU, TPR, TR1.
3. 1). What is the RB: RB is the English rubber (rubber) abbreviation; rubber include natural rubber, synthetic rubber, artificial (specifically described in Appendix A). Rubber: for a variety of sports shoes outsole.
3. 2). What is PU: Polyurethane polyurethane synthetic polymer materials, is often used in the hands after the end of dissection based on the large density of durable foam rubber material.
3.3). What is the PVC: polyvinylChloride PVC, translucent qualities of the yellow, shiny. Appears at the inflection bleaching.
3. 4). What is TPU: full name of thermoplastic polyurethane elastomers (Thermoplastic
Polyurethane), it is a diisocyanate and polyol molecules, co-chain extender response to a natural linear polymer.
3. 5). What is TPR: thermoplastic rubber (ThermoplasticRubber),
is a characteristic of both rubber and thermoplastic materials, but also the performance of rubber by thermoplastic processing and recycling, you can use an ordinary plastic molding machine for injection molding, extrusion molding, blow molding rubber products made of the way.
3. 6). What is TR: TPE and synthetic rubber materials, patterns and more with the appearance, feel good, luster brilliant, highly polished, high-tech features, but also 100% recycled materials are environmentally friendly shoes.
sole identification of the materials and characteristics: on the PU, PVC, TPR, RUBBER and other identification!
a) PU is the lightest and most durable of course the price is the most expensive. PU sole material is easy to recognize, very light in his hand, soles of the back of the hole is round.
two) PVC material TPR soles in his hand than the to heavy. TPR material is better than PVC flexible soles, the soles of the holding firm, the next to fall naturally, if it is able to bounce TPR soles of PVC material to be cheaper than the TPR, but the quality is not good, especially In winter, it is easy off the bottom. PVC material has a characteristic that is not the sole injection of holes, as well as with the smell, then taste. stood for a long time, then still president of the white stuff.
three) TR soles surface is bright. than the average TPR soles to be stiffer. TR injection hole of more than TPR. injection hole is very special
weight: RUBBER (rubber) most important, PU, ??EVA lightest material: PU expensive, EVA, TPR moderate, PVC cheapest craft: TPR is a shape to do it, and to process PVC, ABS is generally high heels materials, expensive and hard applications: PVC is used in lining or bear the weight of the parts, or making children shoes; PU leather for shoes can withstand the weight of the fabric or the site. In the bag, the more applicable is the PVC leather. This is due to different items in the bag to wear in the shoes of the feet, will not emit heat; do not bear the weight of the individual. PU, PVC way more easy to distinguish, from the corner to see the end of PU PVC fabric thicker than many also feel there are differences, PU soft to the touch of some; PVC hard some of the feel; can also use fire to burn, PU . . . .
