An abrasion resistant and chemical resistant damper is provided for installation in the sludge transport section of a wastewater treatment system of the type having a damper inlet chute and a damper outlet chute and a damper between the damper inlet chute and the damper outlet chute. The damper is formed from a fabric woven substantially of yarns of high performance material selected from the group consisting of aramid, ultra-high molecular weight polyethylene, and liquid crystal polymer. The damper includes a body having an inlet end and an outlet end, whereby the body creates a volume for sludge to move through. An inlet flange is formed about the inlet end and an outlet flange is formed about the outlet end.

Feathered edges of fiberglass fabrics woven on a shuttleless or airjet loom are secured and prevented from ravelling by a glass yarn coated with a hot melt composition. The coated yarn is woven along the longitudinal edges of the fabric, typically in a leno weave, then heated to thermobond the adjacent glass fibers with the hot melt composition at their crossover points. A procedure for applying a hot melt to a yarn through a heated die is used.
