1. What are the common types of leather?
Answer: Our common leathers include garment leather and sofa leather. Garment leather is divided into ordinary smooth leather, high-grade smooth leather (also known as glossy colored leather), aniline leather, semi-aniline leather, fur-integrated leather, matte leather, Suede (nubuck and suede), embossed (one- and two-tone), distressed, pearlescent, split, metallic effect. Garment leather is mostly made of sheepskin or goat leather; nubuck leather and suede leather are mostly made of deerskin, pigskin and cow leather. Household sofa leather and car seat cushion leather are mostly made of cow leather, and a small number of low-end sofas are made of pigskin.
2. How to identify sheepskin, cowhide, pigskin, deerskin garment leather?
Answer:
1. Sheepskin is further divided into goat skin and sheep skin. The common feature is that the leather grain is fish-scale, the goat skin has a fine grain, and the sheep skin has a slightly thicker grain; the softness and fullness are very good, and the sheep skin is softer than the goat skin. Some, generally high-end clothing leather is mostly sheepskin. In addition to being used as clothing leather, goat skin is often used in the production of high-end leather shoes, gloves and soft bags. Sheepskin is inferior to goat in terms of fastness, and sheepskin is rarely cut.
2. Cow leather includes yellow, yak and buffalo leather. Yellow cowhide is the most common, which is characterized by uniform and fine grain, such as small pits hit by drizzle on the ground, thick skin, high strength, fullness and elasticity. The surface of buffalo leather is rougher, the fibers are looser, and the strength is lower than that of yellow leather. Yellow cowhide is generally used for sofas, leather shoes and bags. For example, it is used in clothing leather, which is generally high-grade cowhide suede, nubuck leather, and buffalo cowhide as veneer to make fur-integrated leather (the hair inside is artificial hair). The cowhide has to be cut into multiple layers, and the top layer has the highest value because of its natural grain; the surface of the second layer (or the skin below) is artificially pressed grain, which is stronger and more breathable than the top layer. The skin difference is too far, so the value is getting lower and lower.
3. The distinctive features of pigskin are rough grain, tight fibers, large pores, and the three pores are distributed together in the shape of a character. Pigskin has a poor hand feel, and is generally made of suede leather on clothing leather to cover up its large pores;
4. Deerskin is characterized by large pores, a single root, a large distance between pores, and a slightly lighter feel than pigskin.
Well, generally suede leather is used on clothing leather, and there are many suede shoes made of deerskin.
3. What is glossy leather, aniline leather, suede leather, nubuck leather, distressed leather?
Answer:
1. Animals go through a complex physical and chemical treatment process from raw hides to leather. The main processes are soaking, meat removal, hair removal, liming, degreasing, softening, pickling; tanning, retanning; splitting, smoothing , neutralization, dyeing, fatliquoring, drying, softening, flattening, leather grinding, finishing, embossing, etc. Simply put, animals are made of raw leather, and then the grain layer is coated with dyes (color paste or dyed water), resins, fixatives and other materials to make glossy, coated leather of various colors called glossy leather. . High-grade glossy leather has clear grain, soft hand feel, pure color, good ventilation, natural luster, and thin and uniform coating; low-grade glossy leather has thicker coating, unclear grain and high gloss due to more injuries. , feel and breathability are significantly worse.
2. Aniline leather is a leather that a tannery selects from the leather that has been made into leather (no damage on the surface, uniform grain), and is lightly finished with dyed water or a small amount of color paste and resin. The original natural pattern of animal skin is preserved to the greatest extent. The leather is very soft and plump, with good air permeability, bright and pure colors, comfortable and beautiful to wear, and a notable feature when identifying it is that it turns black when it meets water. Most of this kind of leather is painted in light color, and the imported garment leather is mostly aniline leather, which is expensive. Care must be taken when maintaining this kind of leather, and it should be carried out in strict accordance with the operation procedures of aniline leather, otherwise it will bring irreparable losses.
3. Suede refers to leather with a suede-like surface. It is generally produced from sheepskin, cowhide, pigskin, and deerskin. The front side of the leather (the long hair side) is ground and it is called nubuck; Leather; made of two-layer leather is called two-layer suede. Since suede has no resin coating layer, it has excellent air permeability and softness, and is comfortable to wear, but it has poor water resistance and dust resistance, and it is more difficult to maintain in the later period.
4. The production method of nubuck leather is very similar to that of suede leather, except that there is no velvet fiber on the surface of the leather, and the appearance looks more like water sandpaper, and nubuck leather shoes are common. For example, the leather made of sheepskin or cowhide front matte is high-grade leather.
5. Distressed leather and antique leather: The surface of the leather is deliberately made into an old state by finishing, such as uneven color and thickness of the coating layer. Generally, the distressed leather needs to be unevenly polished with fine sandpaper. The production principle is the same as stone-grinding blue denim. , in order to achieve its distressed effect; and antique leather is often painted into a cloudy or irregular stripe with a light background, dark and uneven complexion, and looks like unearthed cultural relics, and is generally made of sheepskin and cowhide.
Four. What items should be checked when a dry cleaner picks up a leather jacket?

Whether the individual has been exposed to jacket oil and has become flowery. 4. Whether you have been treated with lanolin or Pili Pearl, the leather coats with such materials are very easy to fade after coloring. 5. Whether the individual has been washed with water. 6. Whether the leather is moldy or deteriorated. 7. Whether it has become hard and shiny due to the use of low-grade domestic materials. 8. Whether the suede and matte leather have been painted with resin-containing pigments. 9. Whether the buttons are complete.
