Engineering Overview
PAPTEX Flat Yarn Dryer Fabric is our best-selling dryer section solution, trusted by mills worldwide for its reliable heat transfer and consistent moisture removal. The flat yarn profile creates a smooth, uniform surface that maximizes sheet contact and heat conduction while maintaining engineered air permeability for effective ventilation.
Available in two models — SJ22708 (lower permeability for tissue and lightweight grades) and SJ22808 (higher permeability for packaging and board grades) — both feature 100% hydrolysis-resistant polyester monofilament construction rated for continuous operation up to 180°C. The flat profile also minimizes sheet marking, making it suitable for quality-critical grades.
Field results from Sun Paper (Shandong) demonstrate a 28% improvement in drying efficiency and a 21% reduction in steam consumption after switching to PAPTEX flat yarn dryer fabrics.

Frequently Asked Questions
Common questions about Flat Yarn Dryer Fabric
SJ22708 is optimized for lower air permeability (200–400 CFM) for tissue and lightweight grades where heat transfer is the priority. SJ22808 provides higher permeability (500–800 CFM) for packaging and board grades requiring more ventilation. Our engineers will recommend based on your dryer configuration.

Spiral Dryer Fabric
PAPTEX Spiral Dryer Fabric is engineered for the most demanding dryer section positions — high-temperature, high-tension applications where conventional flat yarn fabrics fall short. The spiral yarn construction delivers ≥70 kN/m MD tensile strength, the highest in our dryer fabric portfolio, combined with an open weave structure providing 400–1,000 CFM air permeability for maximum moisture evacuation. Constructed with hydrolysis-resistant PET spiral yarns (with optional stainless steel reinforcement), this fabric maintains dimensional stability at continuous operating temperatures up to 180°C. The spiral structure also provides natural flexibility that resists edge curl and tracking issues common in high-tension positions. A Thailand customer documented 167% longer service life (8 months vs. 3 months) with deformation reduced from 15% to just 3% after switching to PAPTEX spiral dryer fabric in their kraft machine's hottest dryer group.

Dryer Fabric
Round Yarn Dryer Fabric
PAPTEX Round Yarn Dryer Fabric is purpose-designed for quality-critical paper grades where surface marking must be eliminated. The round monofilament profile creates a smooth, mark-free contact surface while maintaining uniform air flow channels through the fabric structure — ideal for tissue, printing/writing, and specialty paper grades. With 300–700 CFM air permeability and ≥45 kN/m MD tensile strength, this fabric performs reliably at speeds of 400–1,000 m/min with continuous heat resistance up to 170°C. The round yarn geometry also provides natural resistance to contaminant buildup, reducing cleaning frequency. A preferred choice for cultural paper mills and tissue producers where sheet surface quality directly impacts customer satisfaction and product grade classification.
