In terms of the difference between artificial leather and leather, the hand feel is relatively different. When touching the leather surface with your hand, the leather is relatively smooth, plump and elastic. Compared with ordinary artificial leather, it is more rigid, astringent and soft. In terms of texture, the leather surface mainly has clear patterns and pores, while the cattle hide has symmetrical fine pores. Although the yak skin has thick and sparse pores, the goat skin has fish scale like pores, and the pig skin mainly has triangular coarse pores. Although the pores are constantly imitated in the artificial leather, they are relatively unclear and the taste is more different, All genuine leather has a smell of natural leather, while artificial leather has a more pungent smell of plastic
Artificial leather is mainly made and processed on textile cloth base or non-woven cloth base under Pu or PVC coating and foaming in various formulas. It is mainly made and processed according to different colors, intensities, patterns, gloss, etc. it has the characteristics of good water resistance, various varieties, high utilization rate, neat edges and low price, However, most artificial leather cannot achieve the effect of real leather in terms of elasticity and hand feel, so from its longitudinal section, you can see a subtle bubble hole, and the surface film and cloth base are the same dry man-made fiber
In terms of artificial leather, the components can be divided into PVC. The products after combustion mainly include carbon dioxide, water and chlorine compounds, and chlorine may be produced; The second is mainly PE material, which theoretically produces only carbon dioxide and water after full combustion The third kind is also very common. It is mainly called PU leather. After full combustion, the products include carbon dioxide and water, Nitrogen is the same as a small amount of nitrogenous compounds
In fact, when we burn these artificial leather, there are some other ingredients involved. When processing and producing these artificial materials, we need to constantly add some solvents, such as leveling agent, initiator, thickener, surfactant, etc., which will more or less remain in the artificial leather. The ingredients after combustion should see what additives are used In the combustion products of artificial leather materials, many compounds are harmful to human body, so we can't just burn our artificial materials casually
