Problems solved by technology

Compared with natural leather, synthetic leather is closer to real leather in terms of hand elasticity, strength, elongation at break, and hygroscopicity, but synthetic leather has a strong irritating plastic smell, which is different from special leather such as animal fat in real leather. The breath is far from each other, which also limits the further development of synthetic leather to a certain extent.
