woven Weave Black Fiberglass Cloth filter used for filter bag
This kind of glass fabric is used for making filter bag. It's used in cement, steel plant and so on.
Triple finish: The triple finish was one of the earliest finishes developed for filtration from chemical attack. The triple finish is now used primarily in cement production and metal foundry applications.
PTFE finish: A ten Percent add on of PTFE particles, such as Dupont's PTFE B, encapsulates the glass fibers to prevent abrasion. However, because PTFE don't bond to the glass filaments, acids or alkalis can attack fabric with a PTFE finish chemically. Fabric with PTFE finish is recommended for use with utility base load boilers operation under mild PH conditions.
