Pull-up refers to the specially processed leather that will change color after being stretched or compressed. It was originally invented by the shoemaking brand HorweenChromexcel established in the 1920s. The use of PULL-UP will make the wear and scratch of shoes not obvious. Compared with other leather products, there is no need for deliberate maintenance.
Polyurethane artificial leather can be divided into dry polyurethane artificial leather and wet polyurethane artificial leather. The so-called dry-process polyurethane artificial leather refers to the multi-layer structure formed by volatilizing the solvent from the solvent-based polyurethane resin solution, and adding the multi-layer film and the backing cloth. The wet polyurethane artificial leather is a multi-layer structure with good permeability and moisture permeability and continuous porous layer, which is obtained by using solvent-based polyurethane resin and water film forming method.
