Many friends believe that there may be hundreds of sofa brands, but nothing more than fabric sofas and leather sofas. Besides, the fabric of the leather sofa is simpler than the fabric sofa.
In fact, there is still a lot of learning inside. If you don't understand, you are likely to be bought a set of leather "normal leather sofas" at a high price. We can't help but ask, is the leather of the leather sofa just cowhide? No pigskin, horseskin, suede, sheepskin... What? Even the cowhide is the original cowhide? No processing? Why are some leather sofas unusually natural, and some leather sofas look bright and bright? These problems, furniture fans will discuss with you.
What is leather
The leather is actually a general term. Pig skin, horse skin, suede and cowhide can be used as the raw material of the sofa. You must figure out what kind of leather is used. With this one alone, you can remove the leather sofa by a few. How much is the amount of other leather.
In general, the thickness, density and distribution of the pores on the leather surface are the main basis for distinguishing between cow leather, pig leather, horse leather and sheep leather.
Cowhide: smooth and delicate, clear texture, soft color, uniform thickness, large skin, suitable for sofa fabric; cowhide, yellow cattle leather and buffalo leather are called cow leather, but there are certain differences between them. The pores on the surface of yellow cattle leather are round. Shape, straight into the leather, the pores are tight and even, irregularly arranged, like a starry sky, the pores on the surface of the buffalo leather are thicker than the yellow cattle leather, the number of pores is less than that of the yellow cattle leather, the leather is slack, not as good as yellow The cow leather is delicate and plump.
Pig skin: rough leather, poor gloss, not suitable for sofa, the pores on the surface of pigskin are round and thick, and extend into the leather obliquely. The pores are arranged in groups of three, and the leather surface has many small triangular patterns.
Sheepskin: The skin is small, the leather surface is thin, the grain is regular, the hand feels flexible, the pores of the sheep leather are oblate, the pores are clear, and several pieces are grouped together, which are arranged in a fish scale. Due to the adaptation of the processed fabric, it is often necessary to splicing. Beautiful.
Horse skin: The pores on the surface of the leather are elliptical, slightly larger than the pores of the yellow cattle leather, and the arrangement is regular.
Generally, high-grade leather sofas use cowhide, and cowhide is divided into yellow cowhide and buffalo leather according to the type; it is divided into top layer skin, second layer skin and three-layer skin according to the number of layers; it is divided into domestic skin and imported skin according to the origin; The top layer of yellow cowhide imported from Italy and Germany has the best quality and meets strict environmental requirements. It has high color fastness, good elasticity and permeability, high mechanical strength, especially high tear strength and tensile strength. Must be the first layer of yellow cowhide.
The true leather sofa of each set consumes the equivalent of 10 cows' cowhide . It has high value, good ventilation and environmental protection performance. It is widely used in developed countries such as Europe and America. The price is relatively high; most enterprises on the market according to consumer needs It also produces and sells half-skin sofas. According to this classification, leather sofas are divided into full-leather sofas and half-skin sofas. Half-skin sofas are made of PU leather or artificial leather PVC instead of cowhide on the back, bottom and other hidden parts of the sofa. The direct contact area of ​​the human body is still a higher value cowhide, which reduces the cost of the sofa and is more economical.

There is also a classification method for leather fabrics according to the texture and appearance of leather: there are four kinds of all-green skin, semi-green skin, embossed skin and crack skin. The former one is generally expensive, but the quality is superior; the latter two are relatively cheap, It is used by ordinary families.
First, all green skin
All green skin, also known as full grain leather, is made from the finest raw material skin, with less disability and a good natural state on the leather surface. The all-green coating is thin and can show the natural beauty of the skin, and it is wear-resistant and breathable. The whole skin is directly dyed by blue warm skin, rejecting too many chemicals, so the skin can be clearly See fine pores, realism and breathability.
The price of all green skin is the most expensive in the leather type, but it is not complicated in the process of making leather and chemical materials, but in the quality of the skin, the difference between the high-grade whole green skin and the ordinary skin is: The skin embryo must be housed in captivity, and the castrated cowhide, because the fiber structure of the bull hide is relatively dense, and the width is large, the most important thing is the captivity, so that the leather surface is less scarred, this is the production of high-grade The upper selection of the leather material, followed by the manufacturing aspect, makes the overall effect more noble and elegant! Such a whole green skin can only be imported, and China can't do such a craft! It has also been said that this all-green skin is the best of the Italian skin, and it is rare in the market.

Second, semi-green skin
Semi-green skin, also known as two-layer leather, refers to the thicker cut of the lower layer after peeling off the original skin, that is, the whole green skin. Compared with the whole green skin, there are more scars and blinks, which need to be moderately polished to be used as a sofa skin. Because the semi-green leather finished sofa is still full of realism, the sense of look, texture and comfort are good, so it is still top grade in the skin, but the price of semi-green skin is much cheaper than that of the whole green leather sofa, which is the choice of most consumers.
Third, embossed leather
The embossed skin actually belongs to the semi-green skin, which is a thin layer of semi-green skin cut after the original skin is peeled off. These batches have heavier scars and deeper eyes. They need to be deep-ground and refilled and then selected as sofa skins. Because the surface texture and texture are poor, in order to make up for this deficiency, most of the process is embossed, and when the semi-green skin and embossed skin are lightly pressed by hand, there are many wrinkles, but the color is rich, the style is changeable, and it is easy to select. .
Fourth, crack skin
The cracked skin is also a semi-green skin. The surface of this type of skin is almost flawless. The use rate is very high, but the texture is stiff and poorly breathable. When the hand touches the surface of the leather, there is a very obvious waxy texture. The coating is very thick and ordinary. The sofas are made of such materials, and some people call them waxed leather.
Features: texture and touch are harder, due to more manual processing, so there is not much sputum on the appearance, but the artificial traces are more obvious in appearance, slightly less natural and moderately priced.
Buying Tips: You can compare and judge the feelings, gloss, texture, workmanship, etc., mainly pay attention to the difference between the distinction and the imitation leather, to prevent the false.
Screening of leather fabrics:
We focus on cowhide: leather sofas are generally made of cowhide. Like the age of the tree, the cow faithfully and accurately records the life course of the cow. It suffers from trauma, struggle with the same kind, and is attacked by beasts. There are no two identical cowhide in the world. The leather has natural pores and skin texture, and it is full, soft and elastic.
1. Look at the structure: natural leather has regular natural pores and skin textures, but there are no imitation leathers. Even if they are artificially made, they are easier to distinguish. In addition, they can be distinguished from their sections. Natural leather is made of leather fibers. And imitation leather does not have this structure.
2, feel the touch: generally identify the leather sofa can be touched by hand. The leather is touched by hand, giving the impression that the texture is quite soft and has a warm feeling. The hand has a certain sense of attachment when moving on the surface of the leather but does not make people feel slippery. The imitation leather has a sticky feel, and at the same time, because of the heat transfer of the leather surface, it has a cool feeling.
3, in addition to distinguish the leather sofa can also be pressed by hand. When the surface of the leather sofa is pressed up by hand, the wrinkles around it are symmetrical, natural, the fabric is thick and solid, but the imitation leather is not, and its appearance is unnatural and uneven.
Therefore, when purchasing a leather sofa, the leather surface should be rich and lustrous, no scars, and the texture of the texture should be fine. Use a fingertip to pinch a place to squat up. It should be soft and strong. After the sitting, the wrinkles can be disappeared or not obvious. This kind of leather is fine and good.
4, Ignition: tear off a little fiber from the back of real leather and artificial leather, after ignition, where the pungent smell, the formation of sputum is artificial leather; all hair odor, not hard 是 is the leather.
