Double Warp Dryer Fabric

Our double-warp dryer fabric features a separated double warp system – two independent warp yarn systems running in separate layers. This advanced construction delivers several operational advantages:

· Minimal air entrainment – The open, non-air-carrying structure reduces the amount of air drawn into the dryer pocket area

· Even surfaces on both sides – Balanced topography ensures uniform sheet contact and consistent heat transfer

· Superior dimensional stability – Two separated warp systems provide enhanced structural integrity and reduced stretching

· High contacting area – Maximum sheet-to-cylinder contact for optimized heat transfer efficiency

Key Benefits

A. Superior Heat Transfer & Energy Efficiency

· High contacting area (up to 58% vs. 30–40% for conventional designs) delivers maximum heat transfer from dryer cylinders to the sheet

· Reduced air carrying minimizes sheet fluttering in the pocket area

· Lower drive power demand translates into annual energy savings

B. Excellent Wear Resistance & Extended Service Life

· Durable double-warp structure withstands high temperatures and abrasion from stabilizer seals and corroded rolls

· Two-Warp-Layer structure provides security– if one layer wears out, the other remains intact and keeps fabric running

· Fabric tensile strength of approximately 220 kN/m and seam strength up to 70 kN/m

· Extends running life by an average of 15–30%

C. Superior Sheet Running Stability & Quality

· Smooth, even surfaces on both sides minimize sheet fluttering and reduce sheet breaks

· Low air carrying improves sheet control and runnability

· No seam marking ensures mark-free sheet surface

D. Operational Efficiency

· Quick and easy seaming with fast tail threading reduces machine downtime

· Excellent cleanability for extended operational intervals

· Thinner, lighter construction reduces sheet stretching and simplifies installation

Applicable to Paper Grades

· Packaging & Board paper

· Printing and Writing paper

· Specialty paper

Customization Options

Depending on customer requirements, we could also offer:

· PPS (polyphenylene sulfide) yarns combined with double-warp design for enhanced thermal resistance and hydrolysis resistance

· Anti-contamination design could also be combined with double-warp design for improved contamination resistance

Our Advantages

· High operating efficiency – Fewer sheet breaks reduce unscheduled downtime and improve overall machine productivity.

· High heat transfer efficiency – Superior thermal conductivity results in significant energy savings.

· Long service life – Hydrolysis and corrosion resistance ensure extended fabric durability.

· Easy installation – Diverse seam technology with seaming aids enables fast, easy and reliable installation.

Summary

Our double-warp dryer fabric delivers superior heat transfer through maximum sheet contact, extended service life through wear-resistant dual-layer construction, enhanced sheet quality through reduced fluttering and non-seam marking, energy savings through minimized air carrying and lower drive loads, and reduced downtime through quick seaming and excellent cleanability.
