Press Felt Type A

Press Felt Type A is a consumable component used in the press section of paperboard production machinery. It is designed to provide uniform dewatering, improve sheet strength, and enhance the final quality of paperboard. With its durable structure, long service life, and stable performance, this Press Felt is a practical choice for professional paperboard production lines.

After the sheet leaves the forming section, a considerable amount of water remains within its fiber structure. If this water is not removed evenly, problems such as sheet deformation, uneven thickness, and increased energy consumption in the drying section may occur. Using a suitable Press Felt Type A helps improve dewatering performance, maintain more consistent sheet quality, and reduce the workload of the drying section.

Why Use Press Felt Type A?

Press Felt Type A applies uniform pressure to the paperboard sheet and helps remove water from the fiber structure in a controlled manner. This process contributes to more consistent moisture distribution across the length and width of the sheet and helps reduce unwanted deformation.

In addition to effective dewatering, uniform pressure improves fiber-to-fiber contact and can increase the density of the paperboard. This can result in better mechanical strength, improved compression resistance, a smoother surface, and higher overall product quality.

Another important advantage is improved energy efficiency. The more water that is removed during the pressing stage, the lower the workload on the dryers. Therefore, selecting the appropriate this Press Felt  can help reduce energy consumption and contribute to lower production costs.

Features of Press Felt Type A

The structure of Press Felt Type A is designed so that the basis weight, or GSM, is controlled through the density of the base mesh. This construction provides good mechanical resistance and makes the felt suitable for demanding paperboard production lines.

The main specifications include:

• Basis weight (GSM): 1200 GSM, with 950–1950 GSM available on request
• Base mesh layers: 2 layers
• Material: 100% polyester
• Batt density: Low
• Dewatering basis: Primarily controlled by the base mesh
• Width: 150 cm

Benefits of Press Felt Type A

Using Press Felt Type A can provide several important benefits for paperboard manufacturing plants.

Improved Product Quality

More uniform moisture removal helps maintain consistent sheet thickness and basis weight across the machine width. This contributes to better consistency and improved final product quality.

Increased Paperboard Strength

Better fiber consolidation can improve mechanical strength, compression resistance, and surface quality. This makes this product particularly suitable for applications where paperboard strength is an important production requirement.

Reduced Energy Consumption

When a greater amount of water is removed during the press stage, the drying section requires less energy. This can reduce the overall energy demand of the production line and lower operating costs.

Longer Service Life

The durable construction of this Press Felt allows it to operate under demanding working conditions. Its structural resistance can help extend service life and reduce the frequency of felt replacement.

Reduced Production Waste

Uniform dewatering helps reduce issues such as sheet waviness, deformation, and uneven basis weight. As a result, using the appropriate press felt can contribute to lower production waste.

Press Felt Type A vs. Type J

Although both types are designed for the press section, their internal structures are different.

In Press Felt Type A, GSM is controlled through the density of the base mesh. This construction provides higher mechanical resistance, strength, and service life compared with Type J. For this reason, Press Felt Type A is particularly suitable for the production of thicker and heavier paperboard grades.

By comparison, Type J contains a higher amount of fiber and is generally more suitable for paper production and lightweight paperboard applications.

How to Choose Press Felt Type A

One of the most important factors when selecting this Press Felt is its GSM, or basis weight. A higher GSM generally indicates a thicker and more robust felt that may be better suited to demanding working conditions.

Other important factors include the type of product being manufactured, production basis weight, press load, and machine speed. Selecting the correct Press Felt Type A according to the actual operating conditions can help improve felt performance, extend service life, and maintain consistent production quality.

Conclusion

If you are involved in paperboard manufacturing and need a press felt that provides effective dewatering, durability, suitable mechanical resistance, and stable performance, Press Felt Type A can be a practical choice.

With its robust construction, two-layer base mesh, 100% polyester material, and controlled GSM structure, Press Felt Type A can contribute to better dewatering, improved paperboard strength, lower drying energy requirements, and reduced production waste.

For paperboard manufacturers looking to improve press-section performance and maintain consistent production quality, Press Felt Type A is an option worth considering based on the machine specifications and actual operating conditions.
