Spiral Fabrics

Spiral fabric belts with filling yarns are mainly used as filter cloth, drying media or conveyor belts for solid-liquid separation in belt press filter. They are made with spiral dryer fabrics with extra filler yarns inserted in the spiral loops to reduce the air permeability and thus to reduce the material loss on the fabrics.
