Spiral dryer fabric description

Spiral dryer fabric or screen is an endless construction comprising a plurality of spiral loops of monofilament yarns. The spiral loops linked by a pin yarn inserted in the adjacent holes.

The specially designed spiral structure allows for rapid drainage, superb distortion resistance and eliminates the need for conventional seams compared with the woven polyester dryer fabric.

According to your requirements, polyester spiral dryer fabric can be fabricated with round yarns or flat yarns. In contrast, the flat yarn spiral dryer is recommended to be used in high-speed paper drying machines owing to its smoother surface, better wear resistance, later contacting area, most of all, improved paper drying performance.

Spiral Dryer Fabrics is a medium to high permeability Spiral Dryer Fabrics used in conventional locations. It is made of hydrolysis and abrasion resistant PET, but its edges cannot be reinforced by PPS yarn. Their air permeability ranges from 150 to 900 CFM, depending on the type of filler wire inserted in the spiral. The seam consists of spirals of the same quality and strength as the dry net. Spiral Dryer Fabrics are suitable for drying locations where joint damage usually occurs. They have high diagonal stability and a relatively uniform distribution of tension and air permeability, even when deformed.
