Spiral dryer fabrics are an endless construction comprising a plurality of helical formed loops of monofilament yarns. Polyester spiral belts can operate as dryer fabrics, filter mesh screens or conveyor belts. Spiral dryer fabric is available in a broad air permeability range. Spiral fabrics are easy to fit and install, simple to clean and remain stable even after long running times of operation.
Depending on the intended purpose, the spirals can be made from round or flat wires and have antistatic, dirt-repellent or enhanced abrasion-resistance properties.
