Couro, bonded leather and couro artificial.
Nota extra:
Couro de ovelha, couro de vaca é o requisito nacional do título oficial de especificação de pele de carneiro e couro!
UMA, couro é um gado, ovelha, porcos, cavalos, veado, ou alguns outros animais fora da pele original, após o processo de curtimento de curtumes, feito de uma variedade de características, força, sentir, color and markings leather materials, é a informação necessária de produtos de couro modernos. Enquanto isso, couro de vaca, sheepskin and pigskin leather is used three leather material. Leather is divided into head layer and layer leather.
(1) the first layer of skin is a grain of cattle, ovelha, porco, etc., of the leather with natural scar and blood muscle scar, etc., and occasionally the cuts in the process of machining and low utilization rate of the belly of parts, import of head skin and trace the serial number of the cattle. All full grain can from the thickness and pore density difference is due to what kind of animal leather. Cowhide sort is more, such as cow leather, couro de gado, couro, couro de vaca, grazing oxen, couro de touro não castrado e couro de touro castrado. In China there are cow hide, pele de búfalo, yak skin and zho skin, etc. Enquanto isso, buffalo hide the pores of the thick and thin; Cow leather is a buffalo hide pore thin and thick. Skin pores are more fine and a little slope, there are mainly Sheep skins and goat two kinds big. Pigskin for hairy rule is 3 ~ 5 root a handful of scattered, então é fácil diferenciar, usually use pig skin of artificial breeding, and wild boar, famous South American wild boar, this kind of wild boar is of significant pig skin pores and grain characteristics of collagen fibers because of its special organization structure, can be processed into very soft leather garment leather or gloves, a high value. , ostrich leather, crocodile skin, short nose crocodile, lizard, snake skin, of bullfrog skin, seawater fish skin (there’s a shark skin, bacalhau, SLATE cod croaker fishskin, eel skin skin, pearl skin, etc.), fresh water fish skin (como carpa capim, carp skin scaly skin), hairy, raposa, pele de raposa prateada, Raposa azul, etc.), a pele do lobo, dogskin, rabbit skin is easy to recognize, and cannot be made on the second floor.
Head skin is processed directly from the original skin of various animals, or the thicker cortex of animals such as cows, porcos, horses skin after hair removal cut into two layers, fibrous tissue tight upper others are processed into a variety of head skin.
(2) the second skin is relatively loose layer fiber organization, some chemical materials spraying or covering, PVC, PUfilm.
Because of this, the differences between the first layer of skin and second skin a useful way to skin the longitudinal section of fiber density was investigated. By head skin is thick and thin fiber layer and its closely together slightly loose excessive layer together, com força excepcional, elasticidade e plasticidade e outras características. 2 são tão longas quanto a camada de pele solta de tecido fibroso, as long as after spraying chemical material or polishing ability used to make leather products, mantém sua elasticidade natural e a tecnologia de plasticidade deve apresentar, but strength is poorer, the head skin with the same thickness of demand.
And for now in manufacturing all kinds of leather, tecnologia de processamento de couro alguns diferentes, mas o método da diferença é o mesmo.
Next we introduced all kinds of leather processing oriented leather:
1, the water dyed leather:
Refers to the use of cattle, ovelha, porcos, cavalos, deer head skin bleaching and all sorts of color, such as the drum broke loose, and polishing and processing all kinds of soft skin.
2, pearl skin:
, also known as film leather, along the spine in half, and repair to the belly of loosely knit and some of the limbs open side of the first layer of leather or second leather, laminating various net in its appearance color, metal color, jade-like stone light pearl color, colorful two-color or polychromatic PVC film.
3, pintar:
Second crust spraying various chemical material calender or extinction after processing of leather.
4, face:
Is low head skin billet, appearance for polishing treatment, grinding to the appearance of scars and blood muscle scar, with a variety of popular color skin after plasma spraying, pressed into the skin of the grain or smooth effect.
5, couro gravado:
Usually choose face or edge bead skin to suppress various stripes or picture. Por exemplo, copy crocodiles, lagartos, ostrich skin lines, snake skin, water ripple, the bark of beautiful grain, litchi, imitation deer lines, etc., along with a variety of stripes and plaids, three-dimensional picture or reflect a variety of brand image design drawings, etc.
6, printed or pyrograph skin:
Material with embossed leather is the same, just different processing technology, is printing or hot flipping into various stripes or picture first or second skin.
7, USOS:
Will be polished leather surface disposal and grain scar or coarse fiber abrasion, show neat all embellish leather fibre after dyed a variety of popular colors and become the first or second leather.
8, velvet skin:
Also called Jing skin, is the crust appearance burnish cloth with soft nap, then dyed out all kinds of popular color and skin.
9, laser skin:
Also called laser skin, cite laser technology in leather surface etching stripes pictures of the latest varieties of leather.
Bonded leather: the various animal fee leather and leather scraps from damage, distribution of chemical material processing. A tecnologia de processamento de aparência é a mesma que a face de couro, couro em relevo é o mesmo, its characteristic is the skin edges is neat, utilization rate is high, o preço é adequado; Mas a pele é geralmente mais grossa, a força é mais pobre, pasta, sacos de haste, adequado apenas para a fabricação de conjuntos de tacos de paridade e cintos acessíveis, finalize the design technologies such as the longitudinal section fibrous tissue uniform, distinguishable recognize liquid hybrid fiber coagulation effect.
Três, couro artificial, também chamado de imitação de couro ou borracha, PVC e PU é a tábua de chão dos dados artificiais, e microfibra is the highest quality artificial leather. É no duto têxtil ou base não tecida, por todos os tipos de formulações diferentes de espuma de PVC e PU ou fabricação de processamento de laminação e se tornar, pode de acordo com a força diferente, resistente ao desgaste, graus resistentes ao frio e uma cor e brilho, pattern drawing and other requirements processing, has a wide variety of design and color, good waterproof function, mantenha a aparência limpa, alta taxa de utilização e oferecem características de couro real relativamente baratas, but the vast some artificial leather, sua alça e elástico é incapaz de ser efeito de couro real; Sua seção longitudinal, você pode ver o fino buraco da bolha, cloth base or the surface of thin film and dry dry artificial fiber. É cedo para sempre agora é um tipo de dados muito popular, ser usado para produzir todos os tipos de produtos de couro, or some leather material. É cada vez mais líder em tecnologia de fabricação, são amplamente utilizados no processamento e fabricação de couro de segundo andar.
Especially pay attention to:
Today, very characteristics of genuine leather artificial leather in a growing, sua tecnologia de aparência extrema o tecido fibroso, pode alcançar o papel do couro, its offer and domestic head skin.
The head of the buffalo hide layers of leather, floor leather, bonded leather how difference?
Head skin is exterior layer of the dermis, the first layer of skin is relatively thin some offer high, make furniture comfortable and soft. Usually the first layer is more than 10 yuan a square foot every one. Below the layer of the skin is on the second floor leather. Second floor leather cheaper, more hard, see on the market is very much also, usually on the second floor leather 4-6 yuan a square foot.
Head skin and second floor leather, seção longitudinal de couro da densidade da fibra foi investigada. By head skin is thick and thin fiber layer and its closely together slightly loose excessive layer together; 2 são tão longas quanto a camada de pele solta de tecido fibroso, spraying chemical material or polishing processing.
Will relax after half leather, wrinkles immediately unseen is cowhide, wrinkles unseen is not bonded leather
Leather to identify common sense
1: to identify the real leather
Toque:
Use hand touch leather appearance, como suave, suave, sentimentos cheios e elásticos é couro real; And usually artificial synthetic leather surface hair dry, dull, suavidade.
Vejo:
Real leather surface has the clear hair also, marcações, couro de vaca tem a simetria dos poros, yak skin has the thick and thin pores, the pores of goat skin has been designed.
Cheiro:
Any genuine leather has the smell of leather; The artificial leather has excitant strong plastic smell.
Lighting:
From real leather and artificial leather the reverse side tore off a little fiber, after burning, who announced the blunt nose smell, forming a knot in one’s artificial leather; Announced any hair smell, does not produce hard bumps is genuine leather.
2, identify artificial leather and synthetic leather
With the above four fundamental recognition method, in order to distinguish artificial leather, Couro Sintético, mutatis mutandis, understand and clear. De outros, artificial leather and synthetic leather has the following features:
1, press with finger leather surface, there is no significant pores, wrinkles, such as pressure after the wrinkles, nor significant natural.
2, no pores, couro, this is one of the important characteristics distinguish true and false leather.
3, cut corners burning, relish, but not a hair of coke smell.
3, how difference leather cattle, pig leather, horsehide and sheep leather
The type of leather is not the same, its features and USES are different. The cow leather is fine, por exemplo, força elevada, the most suitable for manufacturing leather shoes, produtos de couro; Sheep leather light, thin and soft, it is the ambition of leather garment fabric; Pig leather breathable moisture permeability function is better.
Pig leather:
Leather looks round and bulky pore, a skewed into leather. Pore is put to a set of three root, leather surface rendering pictures of many small triangle,
Leather cattle:
Cow leather and buffalo leather are called leather cattle, but both also have certainly different. Cattle leather appearance of pores and rounded, straight into leather, strict and uniform pore, put irregular, like the stars. Buffalo leather appearance than cattle leather bulky pore, pore number relatively sparse cattle leather, leathery is loose, as detailed full cow leather.
Cordovan:
MAO also oval leather appearance, slightly bigger than a cow leather pores, put more rules.
Couro de ovelha:
Leather grain of the oval pore, pore is clear, a few root constitute a group, is designed.
Cow skin layers can be cut (at most) can be divided into 8 layer the head the outermost layer of skin, the best quality, second to second floor skin, its strength, elasticity and permeability are not as good as the first layer leather. Car seat is necessary to choose the head skin. Now on the market to sell a composite skin is skin appearance with a layer of film on the second floor, exquisite appearance, looks like the skin, some businessmen to pretend to head skin, fraud users, should pay attention to identify.
