650g PPS And PTFE Blending Needled Felt With Lamination High Temperature Punched Filter Bag Cloths
Description
PPS fiber can keep intensity completely and bear chemistry naturing inherently, keep good filtration performance among the abominable environment, reach ideal service life. In coal boiler, rubbish incinerator, power plant of fly ash filtering of pulse clear dust catcher, PPS filter felts are an ideal filtration material. PPS filter felt is one of the main filter material able to bear the high temperature according to processed of production technology and artificial material of other high-temperature filter felt.

Production Flow
Needled felt, called punched filter cloths too, is a kind of nonwoven fabric, which is used for industry dust filtration. Needled punched felt is made of fiber and scrim, three layers construction with scrim inside. The first step is fiber feeding, and carding, needling, heat treatment, singeing, calendering, impregnation(oil and water proof), lamination (memberance) , inspection and pack , and then ship out.
