After this kind of leather is subjected to external tension (pulling, topping, bending), the color of the leather surface becomes lighter, and the color is restored after the external force is removed. It is called pull-up effect abroad, and it is called discoloration leather in China. Or oil-soaked discolored leather.
is a kind of lightly emulsified mineral oil and polymer synthetic material, which has strong diffusion and diffusion recovery properties (Prapu oil) filled into the leather.
According to the information, the coating of this kind of leather has a certain degree of transparency when it is finished with aniline. When the leather is subjected to external tension (stretching, elongating, bending), it forces the small molecule Prapu oil to follow the direction of the force. The fiber weaving configuration quickly migrates, the fiber bundle loses oil, and the color of the leather surface becomes lighter, while the fiber bundle near the unexposed... less
