[Materials] shoes
Shoe materials based natural fiber fabrics and leather, synthetic materials in modern times an increasing chemical. Fabric shoes can be divided according to the structure (upper material), in the material, base material, accessories Category 4.
1 fabric
There are leather, synthetic leather, textile, rubber and plastics. Shoes fabric multi tanned cattle, pigs, sheep and grain soft leather or soft suede leather and synthetic leather; high-end shoes are also useful in crocodile skin, snake skin, chicken skin. Shoes shoes and more choice of rugged, abrasion, heat, moisture absorption and good woolen cloth, such as Kampot, velveteen, line on the road, corduroy, canvas and gabardine, tweed, navy it, coat it and so on. Various synthetic resins and natural rubber was the main plastic shoes and shoes material.
2. Lining
There are cotton, Hill (cotton) sheep, cotton, felt, fake fur, elastic velvet. Leather shoes in the latter part of the multi-soft texture of the mountains, sheep leather, the first part of multi-purpose canvas; shoes shoes used in most of the qualities of white or bleached fabric; shoes are made with fine canvas lining. Cold winter shoes through the use of blankets or fur tanned for shoes; Bumian boots (shoes) and then usually with a layer of cotton wadding into cotton for years, can also be used for blankets or elastic velvet inside. Some shoes also present foam composite material or resin used to make fake fur shoes.
3 end of material
There are hard leather, soft leather, imitation leather, cloth, rubber, plastics, rubber and rubber foam materials. Hard leather is a cow, made of processed pig skin, used for shoes, a small amount used to make Leather Sole shoes. In addition, extensive use of leather shoes is also the end. Fabric is the traditional cloth shoes main material. The old cloth as raw material processed or fill Xu Bei labeled as eligible for the end of billet, with a rope by hand or machine, or felts sodium into the bottom end of Melaleuca. Mainly PVC plastic resin used for plastic shoes and cloth shoes. Rubber, natural rubber and synthetic rubber for shoes and cloth shoes. Soft leather with leather and natural leather two, used for cloth slippers and soft soles. Rubber and rubber foam material used for shoes and cloth shoes.
4 accessories
There are eyelets (ring, solder), shoelaces, elastic fabric, velcro, zippers, silk, cotton, hemp sutures (rope), nails, rivets, non-woven fabrics, cardboard, used as internal header and the main with with leather, all kinds of ornaments, supporting parts, adhesives and glue, etc.

[End] shoes
[MD, PHYLON, EVA]
1.MD: MODEL or collectively dragon PHYLON
2.PHYLON: (commonly known as the Dragon) is a do shoe sole material used in generally end with a 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.EVA: Ethylene Vinyl 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, TR]
1.RB: RB is the English rubber (rubber) abbreviation; rubber include natural rubber, artificial synthetic rubber. Rubber: for a variety of sports shoes outsole.
2.PU: Polyurethane polyurethane synthetic polymer materials, often used in hands after the end of dissection based on the large density durable foam rubber material.
3.PVC: polyvinyl Chloride PVC, qualities of light yellow translucent, shiny. Will appear at the inflection bleaching.
4.TPU: full name of thermoplastic polyurethane elastomer (Thermoplastic Polyurethane), it is a diisocyanate and polyol molecules, co-chain extender reaction of linear polymer materials.
5.TPR: Thermoplastic Rubber (Thermoplastic Rubber), is a characteristic of both rubber and thermoplastic materials, but also by the performance of rubber processing and recycling of thermoplastics can be used with ordinary plastic molding machine injection molding, extrusion molding, blow molding rubber products made way.
6.TR: TPE and rubber synthetic material, with the appearance of patterns and more, feel better, brilliant color, finish, and high-tech, but also 100% recycled materials are environmentally friendly shoes.
[Identification and characteristics]
1. PU, PVC, TPR, RUBBER
PU is the lightest and most durable of course the price is the most expensive.
PU shoe sole material is easy to recognize, very light in his hand, soles of the holes are round the back.
PVC materials in his hand than the TPR soles to be heavy.
Flexible TPR sole material is better than PVC, the sole firm to hold, the natural fall down, if you can bounce it is the TPR
TPR soles of PVC materials to be more expensive, but the quality is not good, especially in the winter, it is easy off the bottom.
PVC material has a characteristic that is not sole injection hole, and with the smell, then taste. Stood for a long time, then also president of the white stuff.
TR's sole surface is very bright. Than the average TPR soles to be stiffer. TR injection hole of more than TPR. Injection hole is very special.
(2) weight: RUBBER (rubber) the most important, PU, ??EVA lightest.
3 material: PU expensive, EVA, TPR moderate, PVC is the cheapest.
4 craft: TPR is a shape to do it, and to processed PVC, ABS material is generally high heels, expensive and hard.
5 applications:
PVC is used in lining or bear the weight of the parts, or manufacturing children's shoes;
PU leather for shoes you can bear the weight of the fabric or the site;
PVC leather is more applicable in the bag. This is because the bag of items to wear different shoes in the foot, will not emit heat; do not bear the weight of the individual.
PU, PVC's way easier to distinguish, from the corner to see the end of PU thick PVC fabric than many, also feel a difference, PU's soft number; PVC hard some of the feel; can also use fire to burn, PU's taste than the taste of PVC to light a lot.
