Woven Dryer Fabric for Fine Paper Grades

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 FL

KEYLIFE dryer screen DRY FL is dedicated to machines producing fine paper grades, graphical and printing/writing. It is designed for single tier positions where abrasion is critical and positions where zero marking of dryer fabric is required.

Technical superiority:

• Symmetrical design and low thickness for a correct neutral line positioning to avoid any turning rolls bubbles at high speed;
• Extremely flat yarns, creating a super flat surface for low air drag, thus no paper sheet fluttering;
• Excellent dimensional stability to avoid any wrinkles or movements out of the circuit;
• A contact surface two times higher than classical designs for better heat transfer, lower steam consumption and reduced dragged airs(no sheet fluttering & no blowing);
• The same thickness and CFM between seam and fabric, no specific local wear and marking
• Edges treatment for reinforced resistance to mechanical constraints.
