Features & Benefits

Key characteristics that make this product the right choice for your paper machine.

Bridge-Performance Design

2.5-layer construction bridges the gap between standard double-layer and premium SSB triple-layer, delivering near-triple-layer sheet quality at competitive pricing — the optimal cost-performance solution for medium-to-high speed machines.

Balanced Drainage Profile

Extra weft support layer provides enhanced fiber retention (85–92% first-pass) while maintaining excellent drainage capacity (500–700 L/m²·s) for efficient paper machine operation across a wide speed range.

Reduced Wire Marking

Fine top-surface yarn configuration with additional support wefts significantly reduces wire marking compared to standard double-layer fabrics, producing better sheet surface quality for printing and packaging grades.

Excellent Dimensional Stability

Computer-controlled heat setting process ensures ≤0.8% elongation under load, providing stable fabric tracking and consistent performance throughout the entire service life.

Versatile Application Range

Ideal for a wide range of paper grades from lightweight packaging to cultural paper. Customizable surface characteristics allow optimization for your specific paper grade requirements.

Competitive Total Cost

Delivers 50–70 days of service life at a price point 20–30% lower than SSB triple-layer, offering the best return on investment for medium-speed paper machine operations.

Frequently Asked Questions

Common questions about this product — answered by our technical experts.

When should I choose 2.5-layer over SSB triple-layer?
Expand
Choose 2.5-layer when you need better sheet quality than standard double-layer but don't require the full performance (or cost) of SSB triple-layer. It's ideal for medium-to-high speed machines (800–1,500 m/min) producing packaging, cultural, or kraft paper where the 20–30% cost savings over SSB provide the best ROI.
What is the difference between 2.5-layer and standard double-layer?
Expand
The 2.5-layer construction adds an extra weft support layer that provides approximately 25% better fiber support than standard double-layer. This results in reduced wire marking, better sheet surface, and 15–20% longer service life while maintaining similar drainage characteristics.
Can 2.5-layer fabric handle high filler content?
Expand
Yes, 2.5-layer fabric handles filler content up to 20–25% effectively. The extra weft support layer provides enhanced wear resistance against abrasive fillers (calcium carbonate, clay), extending fabric life compared to standard double-layer in high-filler applications.
What is the typical service life?
Expand
Typical service life is 50–70 days on medium-speed packaging and cultural paper machines (800–1,200 m/min). Life expectancy varies with filler content, machine speed, cleaning practices, and paper grade. We provide customized estimates based on your machine parameters.
