Features & Benefits

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

Cost-Effective Foundation Grade

Single-layer construction provides reliable performance at the most economical price point — ideal for lower-speed machines, standard paper grades, and cost-sensitive production environments.

High Drainage Capacity

Open weave structure delivers 600–800 L/m²·s air permeability, providing excellent drainage for machines requiring high water removal rates, particularly in the early forming zone.

Good Fiber Retention for Standard Grades

Optimized weave patterns achieve 75–85% first-pass retention for standard paper grades, providing effective fiber retention while maintaining the high drainage rates needed for efficient operation.

Easy Installation & Handling

Single-layer construction is lighter and more flexible than multi-layer fabrics, making installation faster and easier — reducing machine downtime during fabric changes.

Proven Reliability

Decades of proven performance on lower-speed paper machines worldwide. Consistent quality manufacturing ensures predictable, trouble-free operation throughout the fabric life.

Frequently Asked Questions

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

Is single-layer fabric still relevant for modern papermaking?

Expand

Yes. While multi-layer fabrics dominate high-speed applications, single-layer fabric remains the most cost-effective choice for lower-speed machines (below 600 m/min), older paper machines, and certain specialty grades. It provides reliable performance at the lowest cost per square meter.

What is the typical service life of single-layer fabric?

Expand

Typical service life is 25–40 days depending on machine speed, paper grade, filler content, and operating conditions. On lower-speed packaging and kraft machines, service life typically reaches 30–40 days with proper maintenance.

Can single-layer fabric produce quality printing paper?

Expand

Single-layer fabric is suitable for standard printing and writing paper grades where surface quality requirements are moderate. For premium printing grades requiring minimal wire marking, we recommend upgrading to 1.5-layer or 2.5-layer fabric for superior sheet surface quality.

What advantages does single-layer have over multi-layer?

Expand

The main advantages are: 1) Lowest initial cost — typically 40–60% less than SSB triple-layer; 2) Easier handling and faster installation; 3) Higher drainage capacity — beneficial for machines with limited vacuum capacity; 4) Proven simplicity — fewer variables mean consistent, predictable performance. Choose single-layer when cost is the primary driver and your quality requirements are standard.
