Recently met very customer asked about, leather, fake leather, head skin, second floor leather, PU, PVC, etc this problem. I have been engaged in leather work in China for more than 10 years, and so in here about the personal view, the hope for your help!

A genuine leather
The so-called leather only head skin and second skin
Big head skin made of leather is the raw skin by all kinds of animals and processed directly
And head skin made of real leather bag (specific see style, size)
Relatively second skin is a loose fibre of second part, the chemical material spraying or on the PVC, PU film processing and into. Quality natural skin worse than the first
So the second skin made of real leather purse is relatively cheap many (specific see style, size)

Two making cr3 + liquor.the again
Will the animals all fee skin and genuine leather scraps smashs, allocate chemical raw materials processing is made and be become. Its surface processing technology of leather face with the, embossed leather, its characteristic is hides a tidy, edge efficiency is high, the price is cheap; But leather body general thicker, strength is bad, only good for making parity dispatch box, bars and clubs in the bag, finalize the design process of products and parity leather belt, the longitudinal cut fibre uniform, discernible recognize liquid content of fiber mixed solidification effect
So people always making cr3 + liquor.the again mistake that is artificial leather is actually wrong!
Again commonly made of leather bag making cr3 + liquor.the (specific see style, size)

Three PU and PVC leather (collectively referred to as, artificial leather)
Artificial leather: also called imitation leather or plastic material, PVC and PU, etc the floorboard of the synthetic materials. It is in the textile cloth base or non-woven basis, by all sorts of different formulations of PVC foaming PU, etc and coated or to make the processing, can according to different intensity, abrasion resistance, cold resistance degrees and color, luster, decorative pattern design request processing is made, has various of breed of design and color, waterproof properties is good, keep out appearance tidy, high efficiency and the relative price of leather cheap characteristics, but most of the artificial leather, the handle and elastic cannot reach leather effect; Its longitudinal cut, you can see subtle bubble hole, cloth and the film and dry or surface dry man-made fibers. It is early until now is very popular a kind of materials, widely used to make all kinds of leather products, or part of the leather materials. It increasingly advanced production process, and is being second skin processing production widely adopted. Now, is very genuine leather characteristics of the artificial leather to have production listed, the surface finishing process extremely fibrous tissue and almost hit the effect of leather, its price and the price of homebred head skin polls.
In fact the PU and made of PVC leather
According to the PU, PVC material level different price is different
Such as cheap PU, PVC is only 10 a few bucks a yard
And expensive PU, PVC and even more expensive than genuine leather
Hundreds of thousands of a yard materials have (with my own eyes I had seen in guangzhou a use PVC making bag factory, to more than $1200)
Four about LV
We all know that LV bags are expensive, LV bag in the yuan commonly real $2500 or more, whereas here replica designer handbag price is lower, cortex quality, a little bit than real version by some skin, generally in the market more than $200 (specific see style, size)
But I can tell you in here
LV of take material series the checkerboard series USES the material in addition to match skin color is imported Italian leather outside
Main fabrics and not genuine leather is to take the extremely high expensive man-made leather materials.
Because the British government banned in the domestic sales take animal fur leather
So the mainstream of LV bag is not the most series leather
But the materials in the world is absolutely top man-made leather materials
(LV in Europe, and Asia also have leather series. Such as everyone knows LV water ripple series, LV leather series, etc)
The question everybody can be on the official website LV information!!!!!!!
