Background
The breathability of leather is one of its very important physical properties. As an important dress material, the air permeability of leather is closely related to the wearing comfort and grade of the leather product. Non-leather products have poor breathability and can provide a feeling of oppression when used as apparel and as a material for wearing. The natural leather has more gaps between the interweaving of the collagen fibers and between the fibers, so that the leather product has excellent air permeability.
The polyacrylate emulsion has the advantages of good stability and the like, and can endow leather products with good dry and wet rubbing resistance, moderate extensibility and other excellent characteristics after being coated, thereby becoming the most common leather coating material. However, after the leather is coated with polyacrylate, the coating formed on the surface of the leather is dense, so that gaps of collagen fibers are blocked, the passage of gas and energy exchanged inside and outside the leather is seriously hindered, and the air permeability of leather products is seriously influenced. In order to meet the requirements of people on wearing conditions, in recent years, researchers have introduced materials with porous structures into polyacrylate to increase gaps and gas channels in polyacrylate molecular chains, so that the materials are beneficial to improving the permeation of gas molecules, and the breathability of the leather after coating is improved.
