In the use of specialized equipment and processes in the cleaning process, adding to the mold, sterilization for pharmaceutical, all kinds of bacteria, mold completely removed from the root to avoid the mildew generated. Keep after thorough cleansing, which is to maintain its original appearance, extended wear life has an important role. Speaking of mold, vermin, and I remember one time purchasing the factory did not notice it in the receipt, and that a number of leather a bit damp, the results of all the leather bag exports to the United States, the customer checks to 40% -50% of the package package with handle and make split mold Director, and later had to return the plant to re-turn to do all! Loss-Oh!
2. Frequent use of the best leather bags, and common fine cloth wipe. If you encounter rain and damp or mildew, use a soft dry cloth to remove water-soaked or moldy. But do not smear water and gasoline, because water can make hard leather, leather oil to make gasoline evaporation and dry.

6. Leather bag when not in best to hang up; of course, can also be flat, but to put the surface, so it is something else flattened wrinkling, affecting appearance.
7. Leather bag before hanging about in the collection, not exposure, hang dry in the shade and air can be understanding. To make leather bags to maintain a longer period of time beautiful color, the collection before the skin surface can be coated in a layer of milk or glycerol, long-term storage so that you can not change color. Avoid exposure, broiled, washed, sharp object impact and exposure to chemical solvents.
8. Avoid wet grinding Sharpei should be rubbed raw rubber and special care and cleaning supplies should not be used shoe polish.

First, how to identify the first layer of skin
Laser skin: also known as laser skin, laser reference surface etching in the leather of the latest kinds of patterns, leather varieties.
Second, the regeneration of the skin: the costs of all kinds of animal skin and leather waste after crushing the deployment of chemical raw materials produced. The surface of the repair process skinned with leather, embossed leather, as characterized by a more tidy edge hides, high utilization, the price is cheap; but generally thicker skin body strength is poor, only suitable for making cheap briefcase, trolley bags , club sets and other products and cheap belt setting process, the longitudinal section of uniform fibrous tissue, can recognize the solidification of liquid material effect of mixed fibers.
Third, leather: leather or rubber is also called, is a man-made materials such as PVC and PU in general. It is based on non-woven textile cloth or by a variety of different formulations of PVC and PU, foam or film produced by processing, according to the different strength, durability, reliability and cold color, luster, pattern processed images and other requirements, with a wide variety of colors, waterproof performance is good, neat margins, high utilization and low prices relative to the characteristics of leather, but most of the leather, the feel and flexibility can not achieve the effect of leather; its longitudinal section, you can see tiny bubbles holes, cloth or the surface of the dry film and dry man-made fibers. Even now it is extremely early for a popular class of materials, and is widely used to produce all kinds of leather products, or part of the leather material. It is increasingly advanced production technology, the second layer of skin is being widely used in the manufacture. Today, mimicking characteristics of leather to leather available in a production, it is very base on the surface processes of fibrous tissue, almost leather effect, its price and the price of comparable domestic first layer of skin. 1: Identify Leather
Hand to touch: the touch leather surface, if smooth, soft, plump, flexible feel that leather; and general man-made synthetic leather face astringent, rigid, soft and poor.
Seeing: real leather face a clearer Mao, pattern, yellow leather have a more symmetrical pores, yak skin has coarse pores and sparse, with scaly goat skin pores.
Smell: the smell of leather, all leather has; and leather has a pungent smell of strong plastic.
Lit: from real leather and artificial leather on the back tore off a little fiber, lit, who issued a pungent odor, formed lump is leather; any given hair smell, does not bear a hard nut to crack is the dermis.
2, identifying leather and synthetic leather
With the above four basic identification methods, in order to compare the identification of artificial leather, synthetic leather obvious. In addition, the leather and synthetic leather has the following features:

2, the leather surface without pores, which is an important feature of identifying genuine leather.
3, cut corners burning, flavored, but not the focus of the smell of hair.
3, how to distinguish cow leather, pig leather, horse leather and sheep leather
Leather types, their characteristics and uses are different. Fine leather surfaces such as cattle, high strength, making the most appropriate shoes, leather goods; sheep leather light, thin and soft, is ideal for leather clothing fabric; pig water vapor permeability of leather good performance.
Pig leather: leather surface of the pores are round and thick, stretching leather over the tilt. Pores arranged in a group of three, leather surface showing the pattern of many small triangles,
Cow leather: leather of cattle and buffalo leather are called cow leather, but they also have some differences. Cattle leather rounded surface of the pores, more direct to reach into leather, the pores close and uniform, arranged in irregular, like the stars. Buffalo than cattle leather leather surface coarse pores, pore over the number of rare cattle leather, leathery more relaxed, full and detailed as cattle leather.
Horse leather: leather surface of the hair oval, slightly larger than cattle leather pores, arranged in a regulatory law.
Sheep leather: leather grain oblate pores, the pores clear, a few form a group, arranged in scaly.
Identification of quality leather
Multiple layers of leather can be split (can be divided into up to 8 layers) for the first outermost layer of skin, best quality, followed by the second layer of skin, its strength, elasticity and permeability not as good as the first layer of skin. Car seats must be selected first layer of skin. Now available in the market is the second floor of a composite skin attached to a layer of film on the surface, the surface of fine, looks like the first layer of skin, and some businesses as posing the first layer of skin, cheating customers, should pay attention to recognize.
From a professional point of view, identify the smell of leather from the leather car, specific gravity, light resistance, migration, atomization, thermal yellowing, abrasion resistance, etc. to judge. Since the majority of owners do not have this expertise, is more difficult to judge, may wish to be identified with the following simple way.
1, the label law
Genuine leather, manufacturing date marked on the back, leather factory name of the area and so on. Of course, the date of manufacture should not be too long, more than 3 years should watch for mildew on leather.

4, watch the Law
30 times in under a magnifying glass, you can see the leather is like outside the Earth’s surface, pit pit hole, the air permeability. Subject to wear-resistant automotive leather, light and other special treatment, some pores will be overwritten.
5, the cutting method
The blade cross-section of leather, leather from the outside to the inside surface layer of color to be the same (looks black, dark gray inside, then is normal.) Note whether there are different color below the outer surface of produce, to avoid secondary stain or change color to buy second-hand leather.
6. Swab
Wipe the leather with scouring the surface of oil, watch for the phenomenon of fading and falling, change the color to avoid secondary buy leather.
7, the origin of law
Countries around the world production of leather, but there was Europe (Scandinavia, Italy, Austria and Germany) is more a long history of leather industry, the natural level of the leather processing in Southeast Asia than the low-grade leather is much higher.
