الوصف

Polyester needle felt is the most versatile, most cost effective and most widely used filter medium for dust collection. It is strong, abrasion resistant, can work up to **0°C and has good resistance to common acids, solvents and oxidising agents.

Feature:
1.By using high strength scrim, the strengh of the felt is increased by a wide range.
2. Selecting 1.2D、2D and 2.5D excellent polyester fibers to produce.so this products possess high porosity,good permeability and high effective dustcollecting.
3.By using high lever fibers increase the ability of anti-acid,anti-alkali and the stability of water solution.
4.Smooth surface treatment,high filtration efficience.
5.low operation resistance,saving energy.

Disadvantages
Polyester"s only real weakness is a tendency to hydrolyse at elevated temperature which means that moisture can break down the fibres and cause them to revert to their basic constituents. This results in powdering of the fibres and a serious loss of strength.

Application

Because of its favourable price/quality ratio, polyester is the most common fibre used in filter media.
