Efni:
polyester felt are made of 100% filament polyester fiber.
Náttúrulegur hitastig úr pólýester trefjaþráði er notað ekki ofinn nálarhöggsferli með trefjum svifandi, geimdreifingu einsleitri trefjarklút, pólýester heftatrefjum með pólýester brengluðu garnframleiðslu með nálar heitu, singeing eða húðun á yfirborðinu, svo sem eftir- vinnsla, gera yfirborðsflata hennar slétt, ekki auðvelt að loka á það fyrir ryk, síuefnageposity, gegndræpi er gott, nota mjög víðtæka, sterka mótstöðu gegn efnafræðilegum stöðugleika, ekki aðeins getur síað stofuhita gas, og síað með sýru og basískt ætandi gas, og getur síað, olíusía, vatn er venjulegt hitastig, aðskilnaður á föstu og fljótandi svæði á svæðum eins og tilvalið síuefni.
 
Advantage:
Breaking Elongation is less than 20% for MD and 40% for CMD,low dry shrinkage, can work well in the 130 deg C. the material is cheaper than other material, so widely used in a lot of bag house system.
Polyester fiber needled felt bag surface smooth degree of dynamic resistance of the bag has very big effect. Bag at the beginning of the resistance of porosity depends on the bag itself, and the running resistance is many times larger than the early resistance. Running resistance depends on the degree of the smooth surface of the filter material, ash removal effect, etc. General hope bag in the filter efficiency, guarantee the same air quantity is bigger, the better, the resistance is lower, the better, because it can save a lot of energy. In the use of air blow dust precipitator, at the same pressure, the same air volume of air dust, selection of large quantities of breathable weaving thing to do when the filter bag is better than the effect with less breathable weaving. Therefore, in the guarantee filter material to achieve high filtration precision, how to improve the bag of porosity and increase the degree of the surface is smooth, reduce dust adhesion, reduce the running resistance is filter material factory should first research topic. Our factory developed resinification smooth surface finishing needled filter felt bag, its porosity than common calender finishing above 50%, higher than that of filter material and smooth surface is much greater than the pressure more smooth finish.
