Wenzhou Shoe Material Enterprises Develop Environment-Friendly Synthetic Leather

According to the next path selection of synthetic leather industry in Wenzhou Daily, the word "environmental protection" cannot be avoided. Longwan synthetic leather enterprises have given the answer to how to eliminate pollution, save energy and reduce emissions from the source. Recently, Wenzhou Hongdeli Resin Co., Ltd. successfully joined hands with Dow Group, a Fortune 500 enterprise in the world, to jointly develop the project of producing synthetic leather from waterborne polyurethane, and solve the pollution problem with international cutting-edge technology.

It is understood that one of the sources of pollution in the traditional synthetic leather industry is the raw material oily polyurethane used in leather making. This polyurethane is made with toluene, xylene, acetone, acetic acid, ethyl ester and dimethylformamide (DMF) as the main solvents, which has certain toxic and side effects. The waste gas and liquid from its production are liable to pollute the environment.

"At present, the treatment of pollution effluents mainly adopts the method of recycling, with high cost. If pollution can be eliminated at the source, it is equivalent to process re-engineering, which can realize the whole process of clean production." The relevant person in charge of Hongdeli Resin Co., Ltd. introduced that water-borne polyurethane is simply to use water to replace toxic chemical solvents to manufacture polyurethane, It is a non-toxic environmental protection product, so it will not emit toxic waste gas and liquid waste during the production of synthetic leather, thus effectively solving the pollution problem of traditional synthetic leather industry.

It is reported that the patent achievement of waterborne polyurethane resin was originally obtained by Dow Group, a Fortune Global 500 enterprise, after more than 10 years of research and development. The group's industry covers chemical, pharmaceutical and other fields, and its net sales reached 60 billion dollars last year.
