Title: Innovations by Ching-Tang Wang
Introduction
Ching-Tang Wang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of materials science, particularly in the development of advanced artificial leather and microfiber substrates. With a total of 3 patents, his work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Wang's latest patents is a method for producing ultrafine fiber and artificial leather. This method involves mixed spinning an island polymer and a sea polymer with different dissolving properties at a predetermined temperature. The process produces a non-woven substrate from the fiber obtained, which is then immersed in a polymer. The sea polymer is dissolved and removed to yield an artificial leather semi-finished product. The final product boasts excellent dyeability and advanced fluff-like properties. The ratio of the melt flow index of the sea polymer to the relative viscosity of the island polymer is about 20 to 55, with the relative viscosity of the island polymer ranging from 2.7 to 3.5. The weight percentage of the sea polymer relative to the total of both polymers is approximately 30% to 70%.
Another significant patent is the process of making a splittable microfiber substrate. This invention focuses on a microfiber spun by conjugated melting of high and low crystallization polymers. The resulting microfiber staple retains its unsplitting state during various treatments and is split at the thin film layer surrounding it. This innovative process leads to a microfiber nonwoven web that excels in wiping and cleaning effects, while also producing an artificial leather that is environmentally friendly and cost-effective.
