The protective leather for toe shoes is genuine leather, regenerated leather and artificial leather. Dermis is the raw skin that is stripped from animals and is the essential material for modern leather products. The regenerated skin smashed all kinds of animal skins and leather waste, and manufactured the chemical raw materials. Artificial leather is made on the basis of textile cloth base or nonwoven fabric, made of various kinds of PVC and PU, and can be made according to the requirements of different strength, wear resistance, cold tolerance and color, luster, pattern and so on.
[protective toe shoes] dermis
Dermis is the skin which is stripped from cattle, sheep, pigs, horses, deer or some other animals. After tanning and processing by the leather factory, it is made of leather materials of various characteristics, strength, hand feeling, color and pattern. It is a necessary material for modern leather products. Among them, cowhide, sheepskin and pigskin are three kinds of leather materials used for leather making. The dermis is divided into two types: the head layer and the two layer skin.
(1) the skin of the head is a cow, a sheep, a pig's skin with a grain surface, the skin has a natural scar and a blood rib, and occasionally there is a knife wound in the process and the very low utilization rate of the belly, the import head and the numbered brand of the cow. The whole grain of the skin can be distinguished from the animal skins from the size and density of the pores. There are more kinds of cattle skin, such as cow skin, meat, cattle hide, cattle hide, cow hide, Bull Hide, Uncastrated Bull Hide and castrated bull skin. There are also cattle hide, buffalo skin, yak skin and calf skin in China. Among them, the pores of the buffalo hide are thicker and thinner, while the yellow cattle hide is smaller and thicker than that of the buffalo hide. The pores of sheep skin are thinner, denser and slightly skewness, mainly consisting of two main categories: sheep skin and goat skin. The skin of the pig's skin is a small group of 3~5 roots because of the rule of long hair. It is very easy to distinguish. It is usually made of artificial rearing pigskin and wild pig skin. It is famous for the South American wild boar. This kind of wild boar has more obvious pore and grain features of pigskin. Because of its special collagen fibrous structure, it can be processed into very soft garment leather. Or glove leather, the value is very high. In addition, the ostrich skin, crocodile skin, crocodile skin, lizard skin, snake skin, bullfrog skin, sea skin (such as shark skin, cod skin, fish skin, eel skin, pearl fish skin, etc.), freshwater fish skin (with grass carp, carp skin and other scaly skin), fox skin with hair (Yin Hu skin, blue fox skin, etc.), wolf skin, dog skin, rabbit skin, etc. It is easily recognizable and can not be made into two layers of skin.
The skin of the head is processed directly from the original skin of various animals, or the skin of cattle, pigs and horses in the thicker cortex is cut down into two layers, and the upper part of the fibrous tissue is processed into a variety of head layers.
(2) the two layer skin is the two layer of loosely woven fibrous tissue. It is processed by chemical material spraying or covered with PVC and PU film.
Therefore, the effective way to distinguish the skin of the head and the two layer skin is to observe the fiber density of the longitudinal section of the skin. The head layer is composed of a dense, thin layer of fiber and a slightly loose over layer that is closely connected to it. It has good strength, elasticity and technological plasticity. The two layer skin is only a loose fibrous tissue layer. It can only be used to make leather products after spraying chemical materials or polishing. It maintains a certain natural elastic and technological plasticity, but its strength is poor and its thickness requires the same thickness as the skin. There are also various kinds of leather used for fashion production today, but there are some differences in the processing technology.
[protective toe shoe] regenerated skin
The regenerated skin smashed all kinds of animal skins and leather waste, and manufactured the chemical raw materials. The surface processing technology is the same as the skin of the dermis and the embossed skin, which is characterized by the neat edge of the skin, high utilization and cheap price, but the skin is generally thick and the strength is poor, and it is suitable for making the peaceful price leather belt, such as the flat price public box, the pull rod bag, the ball rod set and so on, and the longitudinal fiber structure of the longitudinal section is uniform. The coagulation effect of liquid mixture can be identified.
[protective toe shoes] artificial leather
Reclaimed leather is also called imitation leather or rubber material. It is the general name of man-made materials such as PVC and PU. It is made on the basis of textile cloth base or non-woven fabric, made of various kinds of PVC and Pu, such as different formulas, such as foaming or mulching. It can be processed according to the requirements of different strength, wear resistance, cold resistance, color, luster, pattern pattern and so on. It has a wide variety of colors, good waterproof, neat margin, high utilization and price. Relative dermis is a cheap feature, but most of the artificial leather, whose hand and elasticity can not achieve the effect of the dermis; its longitudinal section, can see tiny bubble holes, cloth base or surface film and dry dry fiber. It is a very popular material from the early stage until now. It is widely used to produce various leather products or some of the genuine leather materials. Its increasingly advanced manufacturing process is being widely used in the manufacture of two layers of leather.
