Nonwoven Fabric Types BENEFITS OF THE NEEDLING PROCESS Nearly sixteen inches of 100% polyester fibers are layered over a special scrim. These fibers are continually needled and compressed to form a smooth 1/4” material with uniform thickness and consistent airflow known as Polyveyor. This material will not unravel when cut or perforated, so heat sealing is not required on cut edges. This not only adds to the ease of installation, but makes Polyveyor ideal for bends or other unusual shapes that are encountered. When using Polyveyor, there is no need to stretch the fabric during installation because Polyveyor already has the proper permeability. Simply install Polyveyor taut over the air chamber and bolt it in place. The special scrim, constructed for lateral rigidity and superior bolt holding strength, minimizes the sag often found in other air permeable membranes. Finally, the thousands of pores needled into Polyveyor are so fine that product sifting down into the air chamber is minimized or eliminated. Fluidized beds can be found in the bottoms of silos, trailers, railcars, ships, and barges. A wide variety of dry bulk powders are carried using this “Live Bottom” technology for emptying vessels and storage containers. This method is extremely efficient, has a low operating cost and is often the most economical to purchase and install. Polyveyor Needled Polyester High Temp Polyveyor / Kevlar Polyveyor was specifically designed to be the ideal membrane for fluidized bed and air gravity conveyors. The special needled construction provides uniform and consistent air flow across the entire surface of the fabric. This in turn means maximum conveyor efficiency and output. Kevlar fabric is needled onto a Polyveyor 1951 polyester base. This versatile fabric is rated for a temperature of 500°F continuous or 600°F intermittent.
