Regenerated leather technology:
Is to leather fiber, mixed crosslinking fiber, resin and other additives. Its technical process is: leather or regenerated leather material into must scale of skin fiber, and then with the natural rubber, resin and other material, after mixing, compresses it into filter cake; Heat the filter cake, make its surface fiber melt viscosity, each layer of kneading, glue, dehydration, dry, slice, embossing and appearance treatment after get all goods. Primary features: regeneration characteristics of both leather and PU leather, leather fabric is now very common. The same with genuine leather, bonded leather has hygroscopic, permeability, good work also has the same leather softness, elasticity, light texture, high and low temperature tolerance of strong, wear-resisting of pole. Its lack of equality is the difference in the intensity of the thickness of the dermis, and worse than PU, of course, is not suitable for making shoe force large leather goods, etc. Due to the production technology of regenerated leather contrast sensitivity, and can be adjusted in real time, and by adding the dosage of the natural latex, changes in technology formula, the same can make all kinds of different hardness, different intensity of goods to compensate for the lack of her own. Its appearance in the late processing similar to PU, recycled leather in appearance, texture and color is not only the innovation, the new product emerge in endlessly through designs. More importantly she competitive offer, is only one over ten of the genuine leather, PU microfiber, three times as very good value, high cost performance.
The varieties of leather and to identify the difference
Leather is divided into natural leather (leather), recycled leather, artificial leather (PU/PVC). Leather are cattle, sheep, pigs, horses, deer, or some other animals off the original skin, after tannery processing, made from a variety of characteristics, strength, handle, color, pattern leather material, is the necessary information of modern leather products. Leather is usually by the epidermal layer (remove), the dermis, the reticular layer, leather (out) at the grass-roots level, etc. Meanwhile, cattle leather, sheepskin, and pigskin leather is used three leather material.
A, leather, leather and head skin and skin difference on the second floor.
(1) : the head skin refers to with a grain of cattle, sheep, pig skin (dermis), such as leather have natural special texture effect. Imported leather and possibly trace. All full grain can from the thickness and pore density difference is in what kind of animal leather. There are kinds of leather, such as: cow leather (grazing cattle leather, leather, cowhide, bull leather, not castrated bull leather and castrated bull leather), buffalo hide, cow leather, yak skin and skin of zho, cattle leather best belong to shandong, henan provinces in China and central China, but Chinas current need to be imported from abroad each year more than 8400 tons of raw hides, the intention to be success, to fill the gaps in China to produce raw hides.
