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.
Spiral dryer fabric has a specially designed spiral structure that allows for rapid drainage, superb distortion resistance and eliminates the need for conventional seams compared with the woven polyester dryer fabric. Meanwhile, it allows the filtered cakes to be removed quickly.
Spiral dryer fabric must be heat resistant, rugged, and designed for both dryings efficiently and evenly. Each Spiral dryer fabric is produced only client-specific in order to meet the exact specifications of each machine position.
● Spiral dryer fabric is available in a broad air permeability range.

Dryer screen dries paper web after passing a press section by adhering the web to a steam-heated cylinder. In the dryer section of the paper machine, the paper sheet travels around large-diameter heated cylinders, remaining water is removed by evaporation. Spiral dryer fabrics are widely used in various industries as papermaking dryer fabrics, filter mesh belts, or dryer conveyor belts.
Spiral Dryer Fabrics are widely used in many other industries such as food drying, non-woven conveying, printing textile drying and so on.
Spiral Dryer Fabrics belt is mainly used for multi-cylinder fourdrinier paper machine and multi-cylinder cylinder machine, suitable for all kinds of board paper, corrugated paper, kraft paper, bag paper, tube paper, linoleum base paper, train ticket paper, thick board paper, pulp board Paper and heavy-duty writing paper and wrapping paper.
Since the advent of the vacuum washer, Spiral Dryer Fabrics have become a special filter fabric.
Spiral Dryer Fabrics are also used in rotary screen printing machines in the printing and dyeing industry, coal washing machines in the coal washing industry, oven conveyor belts in the food processing industry, etc., to obtain the best performance.
