Introduction to some of the more commonly used method for the identification of head layer skin:

Visual identification method: pattern, such as leather pores should be the first to identify, on the surface of natural leather can see the pattern, the pores do exist, and the distribution is not uniform, the opposite is animalfiber, the side section, level clearly, have lower animal fiber, with fingernailsscraping on will appear leather fiber up there, napped feeling, a small amount of fibres may be falling, and synthetic leather fabric can see the opposite side, no animal fiber, the general skin without pores, but somehave imitation pores, there will be no obvious pores, some patterns are not obvious, or have a regular artificial manufacturing pattern, pores are quiteconsistent.

Method: hand presses down, have a non-uniform leather wrinkles as head layer cowhide, contrary to the false head layer cowhide.

Odor identification method: natural leather in the leather factory, no fursmell. If there is a very strong smell of fur, is not clean, the leather production of the product, easy to back a little. Do clean no fur smell will notreturn slightly. Combustion identification method: the main olfactory burnt smell and ashes, natural leather combustion will emit a smell of burning hair,burning into ashes generally fragile into powder, and artificial leather, post combustion flame is flourishing, shrink rapidly, and a plastic unpleasant smell, burning sticky, cooling will be made after a hard into the massive.

Made of finished products, with fire, is unable to test whether a is made of genuine leather. Because the artificial leather can also use fire to burn.Because the artificial leather can also use fire to burn.

The first layer of skin care instructions:

Try not to exposure to the sun, in the sun broiled or washing; do not impactby sharp objects, to avoid contact with oil, acid and alkaline substances such as.

The first layer of skin to often use fine flannelette. If you encounter damp ormycophenolate borers, available dry cloth dipped in water to clean; but don't water rubbed directly, because it makes the head layer skin hardens.

Keep the head layer skin luster, can regularly use leather brightenercoating, do not wipe oil with leather shoes, leather polishing usually giveonly one to two or three months, good enough to keep the head layer skintexture.

To remind you again car wizard supplies to the supermarket, do not usewashing powder, detergent and other non special leather cleaner forleather cleaner. Because the emulsion oil molecules of these detergentsbigger, not only unable to penetrate the dermal tissue formed within theprotection, but also blocked the dermal pores, make the loss of dermalpermeability, formation and accelerated ageing and cracked leather.
