The advantages and disadvantages of the dermis
Leather: leather belt fabric made by Animal processing and processing.
Advantages: A- toughness, B- wear resistance; C- good permeability, it keeps the natural leather breathable, moisture absorption, soft, wear, comfortable and strong, and so on.
Disadvantages: A- weight (single area); B- component is protein, water absorption easy expansion, deformation.
The advantages and disadvantages of PU
Artificial leather (P Upi): the main use of high elastic fiber composite, with the characteristics of the leather like.
Advantages: A- quality light, B- toughness, C- can be made into the corresponding good air permeability; D- can be waterproof; E- water absorption is not easy to expand, deformation; F-
Disadvantages: not wear-resisting, easy to break; leather expensive, take care of trouble, but durable.
