650g PPS PTFE Blending Needle Punched Nonwoven Felt With Lamination
650g PPS And PTFE Blending Needled Felt With Lamination High Temperature Punched Filter Bag Cloths
Description
PPS(polyphenylene sulphide) polymer is formed by reaction of sulphur with dichlorobenzene. PPS has both high temperature resistance (190℃) as well excellent acid and alkali resistance, although it can be degraded in highly oxidative environments. PPS fiber needle felt is made of imported PPS fiber which produced by Japan, it is the leading varieties of the high temperature fiber material.

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.
