Description

Polyester is the commodity name of polyester fiber. The filter felt made of polyester staple fiber through needling and heat setting has the characteristics of smooth, stable structure, good air permeability and easy cleaning. The product can be used for a long time at 130 degrees C, and the strength loss caused by a short time heating at 150 C can be recovered. After the functional treatment of water repellent, oil proof, film covering, anti-static and coating, the performance of polyester filter felt is further improved, which has the effect of preventing paste bag, improving filtering accuracy, preventing dust explosion and prolonging service life.

* the polyester fiber can also be used in combination with polypropylene, acrylic and other medium low temperature materials.
