Woven Dryer Fabric For Brown Paper Machine

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 CD

Keylife dryer fabric DRY CD is designed for positions where surface abrasion and drying performances are critical; dedicated to any paper machine producing brown grades paper (liner, flutting), and offers an easy installation on paper machine:

• Proper packaging;

• Easy introduction on the position/machine due to an excellent dimensional stability;

• Easy seaming due to stable, regular and large loops.

Technical superiority:

• Very robust flat MD yarns in DRY CD guarantees excellent abrasion resistance and superior mechanical stability;
• Excellent dimensional stability avoids any wrinkles or movements out of the circuit on paper machine;
• The special embedded low profile seam shows 3 times seam resistance to wear compared to standard flat warp;
• The good number of contacting points/cm2 increases heat transfer to paper sheet;
• Extremely flat yarns create a super flat surface for excellent contact fabric/paper/cylinder;
• All monofilament design reduces contamination build up and allows easy on machine cleaning;
• Edges treatment for reinforced resistance to mechanical constraints in paper machine.
