However, there is still a great difference between artificial leather and genuine leather, and one of the main differences is that the back of genuine leather is fibrous fluff and the back of artificial leather is base cloth. Among artificial leather products, the flocked product and the nubuck product are the products closest to the genuine leather, since the flocked product and the nubuck product also have the pile on one side thereof.
In order to generate the nap on the surface of the artificial leather, an electrostatic flocking method or a surface treatment method may be used. The electrostatic flocking method adopts a special electrostatic flocking machine to implant fluff powder into the artificial leather; the surface treatment method is used for treating the surface or the back of the artificial leather and producing small particles similar to fluff after high-temperature foaming. Because the electrostatic flocking method needs glue applying water and fluff powder, and different glue is used for different fluff, the proportion is complex, the style and effect of the product are single, and the hardness and different handfeel cannot be adjusted; in the surface treatment method, due to the limitation of some sheep skin treatment agents, the fluff feeling is not strong, and the fluff layer and the surface hand feeling are not enough.
Therefore, how to provide a coating agent for sheep skin treatment on the surface of artificial leather to make the surface scratch-resistant and have good hand feeling is a technical problem to be solved by the technical personnel in the field.
