Woven Dryer Fabric for Cultural Paper Machines

Description

Woven polyester dryer fabric can be fabricated in single, double or two and a half layers to achieve different air permeability. It is also available in three-shed, four-shed or other various woven patterns based upon request.

Woven dryer fabric influences the drying process by openness and contact area with the paper sheet. Different yarn structures and shapes are used to control air permeability (CFM) and influence properties such as contact area, wear resistance, stability and cleanliness. 

Dryer fabrics are woven with round or flat monofilaments for drying requirements of different paper grades, and different machine speeds. Flat wire dryer fabric is mainly used in the fore heating box of the drying zone, and also can be used for all paper grades.

Normally, the three-shed fabric is perfect for drying papers less than 70g and a four-shed one is ideal for those papers of weight larger than 70g. In addition, woven polyester dryer fabric can be made to custom orders.

Feature

● PPS (Phenylene sulfide) materials are available as a choice to reinforce the edge to operate in severe conditions.

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

● Rectangular or flat monofilament yarns are used as machine yarns and cross-directional yarns to improve runnability, sheet handling and wear potential on high-speed machines.

● We offer special materials for our dryer fabrics to have  the characteristics of high-temperature resistance, abrasion resistance and aging resistance, etc.

Application

The fabric is widely used in papermaking, mining, food, pharmaceutical, printing and dying, and rubber industry. It can be also used as a conveyor belt and the laminating machine belt.

For paper machines, the woven dryer fabrics are suitable for drying packing paper, cultural paper, board paper and pulp board. 

KEYLIFE Dryer Fabric- Style DRY FR

Dryer fabric DRY FR is designed for positions of paper machines where turbulences, sheet fluttering and marking are critical; dedicated to paper machines producing fine paper grades, graphical and printing/writing.

DRY FR, as all KEYLIFE dryer fabrics, benefits of all protection and supports for a fast, safe and efficient on paper machine installation.

Technical superiority:

• High contact area and smooth surface guarantee the successful application of DRY FR on marking sensitive grade paper;
• The aerodynamic surface guarantees low air drag, while the high surface contacting points reduces the sheet shrinkage on sensitive positions;
• The smooth surface, thinner caliper and long cross-over weave design of DRY FR reduce air turbulence and sheet fluttering at high speed paper machines;
• An all monofilament design reduces contamination and allows easy cleaning;
• Edges treatment for reinforced resistance to mechanical constraints
