Description

Technical Field

[0001] The invention relates to the technical field of high-elasticity microfiber leather production equipment, and in particular to high-elasticity microfiber leather production equipment and a production method. Background Art

[0002] High-elastic microfiber leather is a synthetic leather made of a variety of materials such as ultra-fine fibers and polyurethane resins. Its base fabric is ultra-fine fibers, which are a type of non-woven fabric, but the fineness is only 1 / 20 of that of ordinary non-woven fibers or even finer. The diameter of the fibers is thinner than a hair and can imitate the microstructure of natural leather. Polyurethane resin acts as a binder and reinforcing agent to form a tight bond between the ultra-fine fibers, thereby giving the material excellent elasticity and mechanical properties. During the production of high-elastic microfiber leather, the precisely proportioned polyurethane slurry needs to be evenly coated on the treated non-woven fabric substrate.

[0003] In the current process of spraying polyurethane slurry on non-woven fabric substrates, there are several key issues that need to be addressed. First, a large amount of waste gas rich in toxic components will be generated during the spraying process. Since the non-woven fabric substrate needs to be continuously transported, it is difficult to effectively close the spraying area, which makes waste gas treatment challenging and difficult to purify thoroughly. Second, when the existing production equipment is mixing polyurethane slurry, the slurry often adheres to the inner wall of the mixing container, which not only reduces the utilization rate of the slurry, but also causes unnecessary waste of resources.
