veryMany 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 at a high price to buy a set of ordinary leather."Leather sofa". We can't help but ask, is the leather of the leather sofa just cowhide? No pig skin, horse skin, suede, sheep skin......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?
What is leather?
The leather is actually a general term. Pig skin, horse skin, suede and cowhide can all be used as sofa materials. 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.
Clean and delicate, clear texture, soft color, thin and even, large skin, suitable for sofa fabric; cowhide, yellow cattle leather and buffalo leather are called cow leather, but there are certain differences between the two, the pores of the surface of the yellow cattle leather are round, 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, and the leather quality is slack. The yellow cattle leather is full and full.
The cortex is rough and the gloss is poor. It is not suitable for the sofa. The pores on the surface of the pigskin are round and thick, and extend into the leather obliquely. The pores are arranged in three groups, and the leather surface has many small triangular patterns.
The skin is small, the leather surface is fine, the lines are regular, the hand feels flexible, the pores of the sheep leather grain are oblate, the pores are clear, and several pieces are grouped together, arranged in a fish scale. Due to the adaptation of the processed fabrics, splicing is often required, which affects the appearance
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 breathability, high mechanical strength, especially high tear strength and tensile strength. Must be the first layer of yellow cowhide.
The real full set of leather sofas is equivalent to10The cow's cowhide has high value, good ventilation and environmental protection performance. It is widely used in developed countries such as Europe and America, and the price is relatively high. Most enterprises on the market also produce and sell half-skin sofas according to consumer needs. The leather sofa is divided into a full leather sofa and a half leather sofa. The half leather sofa is on the back, bottom and other hidden parts of the sofa.PULeather or artificial leather PVCInstead of cowhide, 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.
Another classification of dermis
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.
1Full 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. It is wear-resistant and breathable. The whole skin is dyed directly 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 among the leather types, but the process of making leather is not complicated. And chemical materials, but in the quality of the skin, the high-grade all-green skin and ordinary skin is different: in the selection of skin embryos must be selected for captive, and castrated bulls, because of the fibrous structure of the bulls Relatively dense, Moreover, the larger the size, the most important thing is the captivity, which makes the leather surface less scars. This is the top choice for making high-grade leather. Secondly, in terms of manufacturing, the overall effect is 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.
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 real, the look, texture and comfort are better, 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.
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 are heavier and have a deeper eye. They need to be deep-polished and refilled and then selected as a sofa skin. 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. .
The cracked skin is also a semi-green skin. The surface of this kind of skin has almost no flaws. The use rate is very high, but the texture is stiff and the air permeability is poor. 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 treatment, so the appearance does not feel too much flaws, but the appearance of artificial traces is more obvious, slightly less natural, moderate price.
How to distinguish leather fabrics?
We focus on cowhide: the choice of leather sofa is generally cowhide. Like the age of the tree, the cow faithfully and accurately records the life course of the cow. It is traumatized, struggles with the same kind, and is attacked by the beast. Therefore, There are no two identical cowhide in the world. The leather has natural pores and skin texture, and it is full, soft and elastic.
1Look at the structure: natural leather has regular natural pores and skin texture, but there is no imitation leather. Even if it is artificially made, it is easier to distinguish. In addition, it can be distinguished from their sections. Natural leather is made of leather fibers. The imitation leather does not have this structure.
2Touching the hand: Generally, 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 the leather surface heat transfer is faster and has a cold feeling.
3Press by hand: When the surface of the leather sofa is pressed up by hand, the wrinkles around the shape are symmetrical, natural, the fabric is thick and solid, but the imitation leather is not, 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 the top. 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.
4Ignite: tear off a little fiber from the back of real leather and artificial leather. After igniting, all the pungent smell is made of artificial leather. Anything that gives off the smell of hair is hard.
