Increasingly technological progress, synthesize and manufacture things, filled with every aspect of our lives, the value of influence in human life caused a huge impact, as it is now already has a "test-tube baby" appears, maybe in the future Perhaps there are "synthetic Baby" appearance, of course, this is just a hypothetical, but we can already deeply felt synthesize technical magic; On the other hand, synthetic manufactured products, the value of which can not be underestimated, But in person at heart, but not to give up material made from natural products, this natural product has been established in people's minds is absolutely irreplaceable value, give an example; diamonds and leather products, natural products are often even more people put it down, and now we have to "natural leather and imitation leather," a simple distinction, let you add some knowledge in the workplace as you little helpful.
(A) natural skin:
A Definition: Any animal of the epidermis, is processed from natural leather tanning, leather living before processing, after processing the epidermis mature skin, and a variety of cooked and then by the appearance of skin treatment (dyeing, painting, rub etc.), that would allow for a variety of consumer products made from leather, we used "leather" call it, in fact, "natural skin" is really saying.
B Features: Natural leather characteristics, surface texture naturally, with a breathable, elongation, good plasticity, toughness, not easy to break, the most suitable leather products, such as shoes, leather garments, handbags, belts, leather gloves.
C Structure: Each natural leather, can be divided into two-layered structure, the outermost layer (surface layer) commonly known as "bead surface layer", the bottom is called "two palm Layer", due to the natural growth of the binding layer, the high peel strength (easy to peel); now described as follows:
1. Bead surface: the surface of the animal skin, due to the relationship between the pores, the "breathability", is thereby obtained, and its pore is formed by the pattern characteristics of the appearance of natural leather, in accordance with different animals, the appearance of the pattern different, such as cattle, birds, snakes, alligators.
2. Two palm Layer: Department of the formation of fibrous tissue proteins, the toughness (breaking strength) poor elongation is small.
(Two) Artificial Leather:(from shoes manufacturer )
A Definition: Artificial Leather of many types, such as PVC (plastic) leather, PU leather (synthetic leather) and other natural leather and imitation leather made collectively, the paper is to make an analysis of PU leather.
B Features: Artificial Leather, by definition, is artificial, it must be made to use artificial pressure roller, roller from the surface of the tread. Therefore leatherette surface pattern consistent with repeated unnatural, in order to facilitate the production system, to avoid extending the length (ie, the general characteristics of the fabric), extending direction is limited, small elongation.
C structures: Artificial Leather is affixed to the base fabric top PU material (if affixed PVC. Material is a PVC leather) is made, in order to mimic the natural leather bead surface layer (exterior) and texture (properties), PU material made films , and then affixed to the bottom of the cover (PU leather cotton mostly napping while), made after the release paper embossed (EMBOSSED), then the colors together, so the cross-sectional surface layer is PU layer display (film), the underlying for the bottom fabric layer, layer to artificially fit, so the peel strength is poor.
(Three) of the imitation leather natural leather comparative table:
Natural leather imitation leather (from women shoes manufacturer
Appearance 1. A pore 1. Close to the natural skin
2. Natural two lines. Artificial Embossed
Cross-sectional one. Bead surface layer 1. PU film
2. Palm fiber layer 2. Soled cloth
Fingerprints 1. Obviously Komon a. Evident in the pattern
2. Not easy to reply to two. Restore slightly faster
Elongation 1. Elongation 1. Small elongation
2. 2 easy retraction. Subject to the restrictions skin
