Historically, the development of artificial leather products has gone through three major stages: PVC, PU, and superfiber. Under the tide of environmental protection at home and abroad, PVC, PU, and superfiber are all undergoing a process of development towards environmental protection.
Among them, the main solutions for PU environmental protection include water-based PU and solvent-free PU. The microfiber synthetic leather also has the potential demand for environmental protection, which is water-based microfiber. This is currently the most high-end artificial leather product, such as the most well-known Japanese Toray used this technology. Now Huai’an Kaiyue Technology Development Co., Ltd. has mastered the water-based superfiber technology, and will launch new water-based superfiber equipment at the new company Jiangsu Huayuan Hi-Tech Co., Ltd.
The reason why the super-fiber synthetic leather is close to or even better than the real leather is that it largely simulates the three-dimensional structure of the real leather. The three-dimensional interpenetrating structure relies on the ultrafine fibers after fiber opening, on the other hand, it relies on the filling of resin to form a skeleton. As shown below:
The enlarged effect on the left:
At present, many domestic ultra-fiber leathers use solvent-based polyurethane resins. Therefore, the finished super-fiber must also face the same problems as ordinary PU, with residual solvent. To solve this problem, many companies have developed water-based resins to be filled in ultra-fine fibers. It can be seen that the position of water-based resin in water-based superfiber is important.
In the application of water-based superfibers, there is still a certain gap between domestic and foreign water-based resins. As far as we know, the water-based superfibers produced by the water-based resins produced by the three Japanese companies and the domestic Huaian Kaiyue Technology have the best performance.
Kaiyue Technology has been developing and producing water-based resins for many years. Our water-based resins have been widely used in water-based shoe leather, water-based clothing leather, water-based home improvement leather, water-based bag leather, water-based packaging leather, water-based microfiber, etc.
