Abstract

With Dacron and fiber as the raw materials, the filter medium is prepared by punching and calendering the sandwich structure which is composed of the carded fiber nets reinforced with Dacron. This filter medium is used to filter oil, water and air. The experiment results indicate that this filter medium is comparable to the British and German products of the same type, and has an excellent effect on filtering impurities, water and oil. The product not only broadens the application fields of filter media, but also has a positive significance in increasing the social and economic benefits of enterprises.
