We choose different type fineness polyester fiber make into the gradient type structure filter material, make the product not only have the common felt's advantage of high voidage, good air permeability, high dust collecting efficiency, long service life, etc. But also have the advantage of the moderate temperature rating, can reach 150℃ at the moment, moderate effect of the anti-antacid and anti-alkali, and has very good abrasion resistance. According to the different requirements of different working condition, surface treatment can be done as singeing, calendering, oil and water proof, PTFE impregnation, coating, laminating process, etc. It can be used in cement, steel, food and other soot filter use.
