Forming fabric is an endless polyester mesh installed in the paper machine forming section (foudrinier, multi wire, crescent former), with only three main functions:
Dehydration: The pulp (concentration 0.1%~1.2%) coming out of the headbox is quickly dehydrated to a wet paper dryness of 18%~28%.
Forming: evenly distribute fibers to form the basic structure and uniformity of paper.
Conveyor: The forming fabric transports the wet web smoothly to the press section, ensuring stable and continuous machine operation.
Material and Performance:
Forming fabric is mainly made of high-quality polyester monofilament (PET), offering excellent strength, wear resistance, dimensional stability, and resistance to high temperature and humidity.
A high-quality forming fabric is an essential endless polyester mesh. We install it in the paper machine forming section. It suits fourdrinier, multi-wire, and crescent formers. As the first critical stage of papermaking, this specialized belt ensures optimal water drainage and precise fiber distribution. Our premium meshes are engineered for exceptional performance across various paper grades. They ensure your paper mill operates at peak efficiency.
The fundamental role of this mesh in papermaking cannot be overstated. We manufacture these products from high-quality polyester monofilament (PET). This provides the outstanding mechanical properties required for continuous, high-speed operation. The advanced PET material offers several critical advantages for paper mills. It delivers exceptional tensile strength to withstand high machine tension without stretching. The superior wear resistance prolongs clothing lifespan, significantly reducing maintenance downtime. Additionally, it maintains dimensional stability under continuous mechanical stress. Finally, the material performs reliably in the high-temperature and humid environments typical of paper mills.
One primary function of the mesh is rapid and efficient water removal. Highly diluted pulp exits the headbox and lands on the belt. The material then quickly drains the excess water. This critical dehydration phase increases wet paper dryness to an optimal 18% to 28%. Afterward, the sheet moves smoothly to the press section.
Beyond drainage, the belt plays a vital role in sheet formation. Our precisely engineered weave patterns evenly distribute wood pulp fibers across the surface. This uniform distribution forms the basic structural integrity of the paper. It ensures consistent thickness, smoothness, and high-quality printability in your final product.
Acting as a reliable conveyor belt, the mesh transports the delicate wet web. It moves smoothly from the forming zone to the press section. This seamless transfer is crucial for preventing web breaks. It ensures stable, continuous machine operation while maximizing your production efficiency.
Understanding different mesh classifications is essential for optimizing machine performance. Paper mills can choose from various weave structures based on machine speed, paper grade, and drainage needs. Below is an overview of the primary types available for modern papermaking.
Single-layer polyester belts are the most fundamental type available. They are highly cost-effective and feature a straightforward weave design. These options are ideal for low to medium-speed machines producing standard paper grades. They offer reliable drainage and easy cleaning.
Double-layer designs feature a more complex structure for enhanced drainage capacity. They provide superior dimensional stability compared to single-layer options. The added layer improves fiber retention and reduces wire marks on the sheet. This makes them an excellent choice for medium to high-speed operations.
For the most demanding applications, triple-layer and SSB (Sheet Support Binder) designs represent the pinnacle of clothing technology. We specifically engineer these advanced fabrics for high-speed paper machines. They deliver superior surface smoothness, maximum fiber retention, and an extended lifespan. These traits make them perfect for producing high-grade tissue, fine writing paper, and premium packaging boards.
Selecting the correct mesh is critical for maximizing paper quality and machine efficiency. Paper mills must evaluate several operational parameters to find the perfect match. To simplify your selection process, consider the key factors outlined in the table below.
| Selection Factor | Description | Impact on Fabric Choice |
|---|---|---|
| Paper Machine Speed | Low, medium, or high-speed operation | High-speed machines require SSB or triple-layer fabrics for stability and rapid drainage. |
| Paper Grade | Tissue, packaging, fine writing paper | Fine paper needs high fiber retention; packaging boards require maximum drainage capacity. |
| Drainage Requirements | The volume of water that must be removed | Double or triple-layer designs offer higher void volumes for superior drainage. |
| Fiber Retention | The need to keep fine fibers on the sheet | Finer top-surface weaves prevent fiber loss and improve the smoothness of the final paper. |
