This site on January 4 hearing, touching: that is to touch the leather surface by hand, if there is a smooth, soft, plump, elastic feeling is the leather; general artificial, synthetic leather surface astringent, rigid, poor flexibility. Look: The surface of the dermis has clearer pores and patterns. The yellow leather has well-proportioned fine pores. Smell: All leather has an odor of leather; artificial leather has a strong irritating plastic smell. Burning: From the back of real leather and artificial leather tear off a bit of fiber. When it ignites, it gives a pungent odor and creates a leatherette. Any leather that emits a scent of hair and does not form a hard cheek. Buckle: Use the nails to crush the skin, if the recovery is fast and there is no trace is the dermis. The dermis has to be refined, so the price is expensive, it is very comfortable to wear, and it won't smell bad for a long time. Because of the more materials and fewer processes, the machine is usually made into a machine that is very easy to rot. If it is worn on a hot day, Really dragged a mud and stinks. So to buy leather shoes, you must buy leather. As we all know: the belt is divided into leather and imitation leather. But most people still can not tell what is leather? What is imitation leather? Let's share with you the most simple, intuitive and practical method. We hope to help everyone. The dermis is made by peeling the animal's epidermis and chemically treating it. The fake leather (mainly PU and PVC) is chemically treated with chemical fiber fabrics. The difference is that the raw materials are not the same. The treatment method in the latter stage is similar, causing the surface effect to be very close and difficult to distinguish. Judging whether the cortex of the belt or leather bag or purse is the most important thing for the dermis is to look from the side of the skin to see if the filler in the skin has fiber or yarn or velvet bottom, and the filler is fiber for the dermis. Seeing the end of the yarn or velvet is imitation leather. Take the side of the belt as an example. We can clearly see the fibrous tissue under the membrane We can clearly see the yarn, and the middle filler like shredded paper is recycled leather. Is a typical leather belt. In the above figure we can clearly see the yarn, the middle filler like shredded paper is recycled leather. Is a typical leather belt. One, genuine leather Refers to the skin of various animals, their common point belongs to the porous material quality, with ventilation, but easy to damp. The leather materials used nowadays include leather, pigskin, sheepskin, crocodile skin, ostrich skin and horse skin. Pig skin Because the pig's hair passes through the cortex to the inner layer, the air permeability and moisture absorption of the pigskin are better than that of the cowhide. However, the pores are thick, and the texture of the product is rough. The texture of the skin is rough, and it is not as good as the cowhide. After processing, the defects can be eliminated. 2. Leather The hide of yellow leather is thin and the hair is not dense, and the hair roots are not deep. Skin direction, fat glands, sweat glands are not well developed and are commonly used as the surface of shoes and bags. Features: Thickness and elasticity of pigskin. Buffalo hides are sparse, with a rough sticky surface, prominent papillary projections and wrinkles, and the skin is of a thinner, thicker, thicker area. It is often used for shoes and mechanical belts and can be bagged after processing becomes soft. 3. Sheepskin Goat skin fiber tissue is firm, soft and elastic. Similar to yellow leather, but thinner, with clear and detailed leather and tactile, strong dermis. Sheep skin and goat skin are similar, but the hair bundles have more glandular and sweat glands. They are especially soft after being made into finished products. They have large extensibility and feel like velvet, but they have low strength and are easy to be rotten. They can only do leather garments and gloves. Can't do uppers and handbags. 4. Horse skin Coarse and cowhide look similar, but the gloss is not as good as leather, the color is dark, the pores are oval, leather is loose and soft, horse skin and sheepskin leather are closer. Comparing the two, horseskin leather is harder than sheepskin and has poor hand feel, uneven gloss, and no wrinkles, but it is relatively easy to break. Second, the leather processed leather Water stained skin, open side pigskin, patent leather, shaved skin, embossed leather, printed after the flower skin, sanded skin, suede, recycled leather, laser skin, leatherette. 5. Water-stained skin - refers to the use of pigs, cattle, horses, sheep, deer, etc. The first layer of skin dyed various colors, and glazing processing of various soft skin. 6. Beaded skin - cut in half from the spine, and trimmed loose and wrinkled intestines and extremities of the first or second layer of open leather, on its surface with a variety of net color, metallic color, Fluorescent pearl color, Symphony two-color or multi-color PVC film processed. 7. Patent leather - Leather with calendered or matted finished chemical raw materials sprayed with a primary or secondary skin. 8. Shave the skin - is a poor scalp blank, the surface is polished, rubbed off the surface of the scars and blood marks, with a variety of popular color paste after spraying, pressed into a grain or smooth effect of the skin. 9. Embossed leather - generally used to make a variety of patterns or patterns, such as trimming the skin or opening beaded skin. Examples include crocodile prints, lizard prints, ostrich skin prints, python skin prints, water ripples, beautiful tree patterns, litchi patterns, imitation deer patterns, and various stripes, checkered patterns, three-dimensional patterns, or reflecting various brand images. Creative patterns etc. 10. Printing or branding - The same choice of materials as embossed leather, but the processing process is different, often printed or hot iron into a variety of patterns or patterns of the first layer or second skin. 11. Polished sand - The surface of the leather is polished, and the grain scars or rough fibers are abraded to expose the uniform and smooth leather fiber tissue and then dyed into various colors to form the first layer or the second layer. . 12. Suede skin - also called ploughing, is the first layer of leather that has been polished into velvet and then dyed with various popular colors. 13. Reconstituted skin - after crushing the waste skin and leather of various animals, the chemical materials are prepared and processed. The surface processing technology is the same as the leather trimming and embossing leather. Its characteristic is that the edge of the skin is more neat, the utilization rate is high, and the price is cheap; however, the skin is generally thicker and the strength is poor, and it is only suitable for making an affordable document case and a drawbar bag. , Cue set stereotypes process products and flat belt, the longitudinal section of the fibrous tissue uniform, can recognize the liquid material mixed fiber coagulation effect. 14. Laser skin - also known as laser skin, citing laser technology to etch the latest leather varieties with various patterns on the leather surface. Third, leather 1. Definition: refers to a more durable material that has been transformed into a series of chemical, physical, and tanning processes. 2, classification: Artificial leather - also known as imitation leather or plastic material, is a generic term for synthetic materials such as PVC and PU. In the late 1940s, polyvinyl chloride-coated products were called artificial leather. It is manufactured on the basis of textile and cloth, foamed or coated with various formulas such as PVC, PU, ​​etc. It can be processed according to requirements of different strength, wear resistance, cold resistance, color, luster, and pattern design. , With a variety of colors, waterproof, good margins, high utilization and the price is cheaper than the leather. However, most of the artificial leathers can not reach the effect of the dermis because of their hand and elasticity. The longitudinal section of the leather can be seen with fine pores, a film on the surface of the cloth or surface, and dry man-made fibers. It is a type of material that has been very popular in the early days until now. It is commonly used to make various leather village products, or some leather ingredients. The advantages of artificial leather are: light weight, acid resistance, resistance to blemishes, oil resistance, folding resistance, imperviousness, bright color and pattern, but no air permeability and no hygroscopicity. Synthetic leather - Unlike artificial leather, a fully formed fiber layer impregnated with a polymer material approximates the fiber structure and breathable moisture absorption characteristics of natural leather. After being made into various leather products, the feel of the leather is almost the same as that of the dermis, but the air permeability is about twice as much as that of the dermis. The leather feels elastic, soft, irregular in texture and cool to the touch. Synthetic skin feels regular patterns of peeling and feels hot. Fourth, the difference between leather and leather 1. The leather feels soft and flexible, and can withstand greater strength and impact. When water becomes soft, it becomes particularly hard after drying, and it is easy to rot. 2, the surface of the synthetic leather is rigid, stiff, low strength, and its service life is not as long as the leather. Fifth, the difference between the first layer and the second layer 1, the first layer of the skin is directly processed by a variety of animal raw skin, or thicker skin of pigs, cattle, horses and other animal skin after cross-section cut into two layers, the upper part of the fiber is processed into a variety of tight The first layer of skin. 2. The second layer of skin is a relatively loose second layer of fibrous tissue that has been chemically sprayed or coated with PVC or PU film. The most effective method of differentiation is to observe the longitudinal section fiber thickness of the skin. Sixth, care 1. The maintenance and care of synthetic leather and natural leather a) Don't put too much stuff, otherwise bags will be easily deformed and easily rot; b) Do not expose to sunlight under the hot sun, otherwise the surface of the leather will lose its toughness and it will break easily. c) Do not place it in a damp place. Otherwise, the leather tissue will loosen easily. d) Unusual leather products need to be waxed, packed in moistureproof bags and checked regularly; e) If the surface is dirty, the surface of the bead bead can be used after the leather cleaner is available; f) If the skin is scratched, use a shoe polish of approximately the same color as the skin on a soft cloth, gently wipe the surface of the scratched position and wait until it is dry and then wax it; g) Avoid exposure to acid chemicals. 2. Artificial leather care and maintenance Due to the poor hygroscopicity and moisture-discharging performance, the handbags should be promptly wiped after getting wet, and they should not be exposed to the sun, nor should they be washed in the water. If there is dirt on the surface, use warm water to add a little diluted detergent. Rub and dry with a dry cloth. 3. Part of the care products a) Soft cloth - waxing, cleaning; b) Begonia powder - protect the metal buckle of leather goods, only need to use a soft cloth to wipe some of the jellyfish powder and rub it on the metal buckle, then you can make the rust and the colored buckle look a new look; c) WD - 40 rust-proof lubricant - if the leather buckle lock does not work, use this agent spray on the lock, anti-rust, lubricating effect; d) Almighty water - clean strong stains (pour wipes on cloth); e) The leather wax masks the scraped places on the leather goods; f) Shoe polish (paste type) - used as a mask to be scratched, a leather-colored shoe polish applied to the top, and then lightly waxed with a make-up wax to restore the natural; g) toothpaste can be used for cleaning. Leather and artificial leather artificial leather (ie, leather, that is, PVC or PU) should be how to distinguish it? 1. If you allow it to burn, it is most straightforward to burn it; from the back of real leather and artificial leather, tear off a bit of fiber. When it is ignited, it gives a pungent odor and forms a leatherette. Any hair that emits an odor that is not hard-coated is Genuine Leather. 2, press the leather by hand, A. natural leather wrinkles, artificial leather wrinkles are not natural; B. carefully look at the pores of the leather, and the surface texture is no rules, no real leather pores, texture is relatively neat; C. Genuine leather The hand feels soft and elastic, and the artificial leather feels hard and does not touch the surface of the leather with much elasticity. If it is smooth, soft, plump, and elastic, it feels like a genuine leather. However, the artificial synthetic leather surface is awkward, inflexible, and has poor flexibility. . 3. Smell with the nose: All real leather has the smell of leather; artificial leather has a strong irritating plastic smell. 4, comparing different leather, a leather product, such as leather bags, leather or leather shoes, is rarely made of the entire skin, so you can look at different small skin, the texture of each small piece of leather is likely to be the same Small, artificial leather each texture is the same; 5, look at the opposite side of the leather, artificial leather generally have chemical fiber fabric or texture, leather only pores; 6, look shiny, soft leather luster, leather brighter luster; 7, look at the price, the price of leather and leather vary greatly in the price, if the leather product price is very low, we must be careful to carefully distinguish.
