(1) The sport sole material is classified with the performance introduction:
Rubber: Used in the large bottom of various kinds of sports shoes.
Advantage : The wearability is good , slip resistance , rupturing flexibly , difficultly, soft degree is better , stretches ductility good , shrinks the stability , hardness good , crooked it is good.
Shortcoming: Weight is heavier , apter to spit the frost (belongs to the quality question ) , difficult to corrode (the issue on environmental protection ).
PU: The high polymer gathers the ammonia fat and formates materials , the daily bottom in the basketball , tennis shoes , can be used in the large bottom of the playshoes directly.
Advantage : The density , hardness are high , wear-resisting , the elasticity is good, the good one is able to bear the performance of oxidizing, apt to corrode and benefit environmental protection, it is difficult to wrinkle rolling over.
Shortcoming: The hydroscopicity change, apt to rupture strongly, easily to be yellow, the coefficient of elongation is bad, able to bear water , perishable in the bottom.
EVA: Second acid ethylene copolymer, high polymer material . Daily jogging, slow step , playshoes , foot train the bottom in the shoes.
Advantage : Light, the elasticity is good , pliable and tough good , difficult to wrinkle, there is extremely good colouring , suitable for various kinds of climate.
Shortcoming: It is apt to absorb water , difficult to corrode unfavorable environmental protection , easy to be dirty.
PHYLON(MD): Belong to the high-pressure shaping product two times of EVA , the main materials in the bottom in running shoes , tennis shoes , basketball shoes in the world, can be used in the large bottom of the playshoes.
Advantage : Light, flexible, the appearance is thin, soft degree is good. Apt to wash, hardness , density , pulling force , tearing, the coefficient of elongation is good.
Shortcoming: It is difficult to corrode unfavorable environmental protection, easy to wrinkle at the time of the high temperature, easy to shrink.
TPR: With TPR grains of material hot note mould shaping after melting, daily on jog , slow step , bottom , large bottom of the playshoes.
Advantage : It is cheap to be apt to mould the shape , price;
Shortcoming: Material serious, wear and tear difference (wear-resisting ), soft degree relatively bad, getting crooked and getting poor is it shake ability bad to sucking
Performance is compared with: TPR large proportion, relatively heavy, the elasticity is general, wear-resisting degree is general. Rubber bottom proportion is relatively large too, but relatively soft, very wear-resisting, it is strong to stress land fertility, but the elasticity is bad, generally used in on indoor football shoes and playshoes. EVA bottom is very light, flexible, the elasticity is reduced after just dressing long, become a bit steady and more sure. Rich flexibly in PU, MD bottom, it is not out of shape to be and prolonged, relatively flexible and comfortable at the time of sports, proportion is small , very light , use than extensive (whether PU result kind great shock attenuation than MD have by density, at the same time relatively serious). The big general films all use rubbers, wear-resisting slip resistance .
At the price, TPR is the cheapest
PU =TPR about * 2 times
MD =TPR about * 3 times
MD air cushion TPR * More than 4 times
PU air cushion TPR * 4- More than 6 times
(2) The sport vamp material is classified with the performance introduction:
The surface fabric of the sports shoes is probably bar of PVC , PU , ox, ultra thin fibre, such several big classes as natural cover , network cloth ,etc., differentiate the brief illustration as follows:
PVC: The great majority are relatively cheap, quality difference is not cold-resistant, not able to bear rolling over ; The products do not need PVC to make surface fabric.
PU leather , bar of ox: Use the most general material on the market at present. PU leather is soft , rich flexibly, feel well, how glossy the surface is! The surface of bar of ox present and rub the sand form more, it is rough to feel, little and glossy and presenting disappearing all fog, the majority has no elasticity . Although bar of ox , PU are different, use and have their own characteristics each. Comparatively speaking it is a little more extensive that PU is used, the price ranges from a dozen to about one hundred. The sports shoes use middle-grade bar of ox and PU leather of the above to make the vamp .
Exceed the thin fibre: The feel is soft , the quality is even , performance is very close to the natural cover, but more even than the natural leather thickness, the elasticity is more balanced, is that the synthetic leather is one of the best materials . Its price is the cheapest in more than 60 yuan for each yard too, the good one is up to more than 200 yuan, most shoes type of ours use this kind of material at present.
Natural cover: It is people materials generally approved, it is ventilative , soft and able to bear stripping , able to bear rolls over , cold-resistantinginging, durable in use, the shortcoming has flaws , there are many pores, it is difficult to tailor that the form is unstandard. The natural cover is always liked by people; The shoes have such a lot of kinds as cow hide , pigskin , deerskin , camel's bird's skin , crocodile's skin , snakeskin ,etc. with the cover. The sports shoes generally use the cow hide. The cow hide can be divided into the first layer of covers and two layers of covers, the first layer also calls the pearl face skin, call two bulky covers or patent leathers on the second floor, the price of generally the first storey of covers is two layers and leather 3- times. Sports shoes, especially the basketball shoes use the first layer of cow hide in a large amount, very valuable.
Network cloth: Dividing three kinds mainly, network cloth of main material , is used in and helped the surface to expose the place , ,light and have the good one and ventilative , is able to bear crookedly, such as the sandwich network cloth. Collarband auxiliary materials such as velvet , BK cloth, the cloth auxiliary materials while having, such as the beautiful new cloth. It is good that the main characteristic is wear-resisting , ventilative.
Note: Sport sole material , vamp material are labelled on the shoe-box, can contrast .
