Polyester woven dryer fabric can be divided into 3-shed,4-shed & 8-shed. Made from high grade flat monofilament and round monofilament polyester yarns.Used in the Drying section of paper Machine to product all kinds of papers.
Dryer screen dries paper web after passing a press section by adhering the web to a steam heated cylinder.
In the dryer section of paper machine, the paper sheet travels around large-diameter heated cylinders,remaining water is removed by evaporation.
So dryer screen must be heat resistant, rugged, and designed for both drying efficiently and evenly. Our Dryer Fabrics lifetime is about 6-18 months generally.
According to the weaving, polyester dryer fabric can be divided into 3-shed, 4-shed. According to the category,polyester dryer fabric can be divided into one and a half layer, double layer and rectangular wire fabric.
We offering for increased drying rate, Improved paper quality and energy savings. it suitable for the fore several heating box of the drying zone, quality papers can use all.
