Paper Machine Clothing Spiral Dryer Fabrics

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.
