22504 Polyester Woven Dryer Screen Mesh Fabric For Board And Paper Machines

Introduction of Polyester Dryer Screen

22504 is mostly used in multi-cylinder papermaking machines. Due to its high air permeability, it is generally used in the second half of the drying cylinder of the papermaking machine. The paper produced is generally more than 70g.

Features of Polyester Dryer Screen

Our woven dryer fabric materials have excellent resistance to hydrolysis in wet conditions and resistance to degradation in dry heat conditions, achieving optimal economic life.

We use different yarn structures and shapes to control air permeability and other characteristics such as contact area, abrasion resistance, stability and cleanliness.

Rectangular or flat monofilament yarns are used as machine and transverse yarns to improve runnability, paper handling and wear potential for high-speed machines.

Special material dryer fabrics have characteristics such as high temperature resistance, abrasion resistance and aging resistance.
PPS (phenylene sulfide) material can be selected to reinforce the edges for operation in harsh conditions.

Precautions​ of Polyester Dryer Screen

The seam is the weakest link in the dryer mesh strength, so great attention should be paid to the threading strength and dryer mesh joint operation;

The dryer mesh seam is also the most likely location for dryer mesh marks on paper. In addition to changing the dryer mesh seam selection, reducing the dryer mesh tension, reducing the large wrap angle of the dryer mesh, and the large bending path can also effectively avoid such problems.

The edge of the dryer net is constantly impacted by the correction feeler. If the edge of the dryer net is poorly woven or hydrolyzed, it is easy to have the problem of edge yarn falling. It is necessary to check it every time the machine stops;

Many times, production personnel will think that dryers of the same or similar length can be interchanged at will. It should be noted here that when selecting the dryer net, the manufacturer has already made a certain match on the dryer net design. The dryer net in the high evaporation section often has a certain resistance to hydrolysis. Therefore, unless there is a shortage of spare parts, it is not recommended to change the position of the dryer net at will.
