Polyester (scientific name: polyester) needle felt, polyester needle felt is the main filter material in bag dust collectors. It uses a non-woven needle punching process to card and lay polyester short fibers into fine fibers with staggered fibers and evenly distributed gaps. The fiber cloth is then needle-punched into felt. This filter material has high strength, good elastic recovery performance, stable fabric size, good wear resistance, large void ratio, good air permeability, long service life, good dust removal effect, and has good mechanical properties and Acid and alkali resistant. Because polyester is cheap, polyester needle felt is a cost-effective filter media at low temperatures.
According to the characteristics of dust from different manufacturers, polyester needle felts are often mixed with antistatic fibers, singed, calendered, water-repellent and oil-proof impregnated, etc. The polyester needle felts produced have additional properties in addition to their original properties. It has the properties of easy dust removal (quick dust removal), water and oil repellency (anti-condensation), and anti-static properties to form a series of products.
.Filter materials are commonly used in the grinding process of cement plants, as well as in industries such as wood processing plants and refineries where the temperature is not high.
.The company currently has the following polyester needle felt series: ordinary polyester needle felt, polyester series easy-to-clean needle felt, water-repellent and oil-proof needle felt, anti-static needle felt, mixed conductive fiber anti-static needle felt , three-proof (waterproof, oil-proof, anti-static) needle punched felt.
