Polyester fiber and non-woven needled felt filtration material made of it
Polyester needled filtration felt is made by polyester fiber and the fabric woven high-strength, low-elongation yarn. The Dacron fibers are needled noto the fabric by needled-punching machine.
Polyester fiber has low absorption of humidity. The water regain rate under standard condition is 0.4-0.5%,while 0.6-0.8% under the condition of relative humidity 100%. Therefore, the fiber will keep almost the same properties in both dry and wet conditions. It shows good resistance for almost all the atmosphere under the room temperature. The strength of the polyester is high and the elastic recovery performance is good. The strength of it is 3.52-5.28CN/dtex, elongation at break is around 30-40%. The polyester has good size stability, high strength, high elongation and good elastic recovery performance. So that, the polyester fabrics has good abrasion resistance. The glass transition point of polyester fiber is 80℃,melting point is 255℃~265℃. It starts to become soft at 230℃~240℃. Polyester fiber has very good application function under room temperature. It is the most reasonable filtration materials for the industry conditions with common temperature.
This product has the advantages of high porosity, good permeability, good abrasion resistance and resistance to acid. The consumption amount of polyester is the biggest among the needled felt filtration material. It is widely used in the fields of metallurgical, chemical, building materials, metallurgy, power generation, ceramics, machinery, mining, petroleum, pharmaceutical, food, dye, mining etc. It is currently the most ideal filtration materials for the common temperature conditions.
