Paper Making Felt
- Material: Typically woven from natural or synthetic fibers such as wool, polyester, nylon, etc. The design focuses on absorbency, elasticity, and durability to withstand the high-intensity operations during the pressing process in papermaking machinery.
- Use: Primarily used in the press section of the papermaking machine to help remove a large amount of water from the paper sheet through physical pressure and to impart a certain texture and smoothness to the paper.
Dryer Screen
- Material: Mainly made from high-strength synthetic fibers like polyester monofilament or flat filament. It emphasizes dimensional stability, breathability, and wear resistance to suit the conditions in the drying section of high-speed papermaking machines.
- Use: Installed in the drying section of the papermaking machine, it acts as a support structure for the paper, allowing hot air to pass through to accelerate the evaporation of moisture from the paper surface while maintaining the flatness and strength of the paper.
Different Uses
- Paper Making Felt: Used in the press section to assist in the removal of water from the paper sheet and to apply a certain texture and smoothness to the paper.
- Dryer Screen: Used in the drying section to support the paper, allowing hot air to pass through to speed up the evaporation of moisture while keeping the paper flat and strong.
Disposal Methods
Both paper making felt and dryer screens require proper disposal after reaching their service life. Traditionally, damaged or severely worn felts and screens may be scrapped. However, with increasing environmental awareness and technological advancements, more and more old felts and screens can be recycled. This can involve regenerating fibers through physical or chemical methods, or, in some cases, repairing them for reuse instead of incineration. The correct disposal method should comply with environmental protection standards, aiming to reduce waste and promote resource recycling.
