Polyester – the most versatile, cost-effective and most common filter cloth for dust collection. It is durable, abrasion resistant, can operate at temperatures up to 150° C and has good resistance to most acids, solvents and oxidants.
Its one weakness is a tendency to hydrolyze which results in a loss of strength and toughness as the fibers break down and turn to powder.
A wide variety of chemical and thermal treatments are available for polyester, the most common being superglaze to improve dust release and liquid repellency to assist with sticky.
