How to identify natural leather and imitation leather materials?

The natural leather (commonly known as the dermis) has natural pores and striae on the surface layer, and the upper joint is cut. From the surface to the inner layer, the process changes from firm to loose tissue. And there are leather fibers. If you take a little light, it has a burning paste.

Imitation leather material (commonly known as fake leather) is not leather fiber, it is a non-woven fabric, coated with a layer of plastic resin processing, from the cut. On the back side, the non-woven fabric or textile substrate can be seen, and after the ignition, there are unpleasant smells of chemical materials.
