BOM press felt classification and structure determine drainage efficiency, durability, and paper quality in modern papermaking press sections.

learn the press felt specifications including weight, length, width and sizing to improve press efficiency and paper quality, ensure stable and efficient operation of the paper machine.

Forming fabric is a key paper machine clothing used for sheet formation, fiber support, and dewatering, improving paper quality and machine operating stability.

This article explains dryer fabric structure, materials, seam joints, and anti-pollution design, and how they affect paper drying performance and fabric lifespan

During papermaking, the press felt is affected by pressing pressure, felt humidity, paper dryness, temperature, and pulp characteristics, which reduces dewatering efficiency. Understanding and learning the principles helps maintain its dewatering performance.

After installing a new press felt, issues such as sheet breaks and uneven dewatering may arise due to improper selection, insufficient cleaning, mechanical wear, or incorrect operating parameters. Sun Hong provides a structured analysis of typical fault sources and outlines corrective measures for improve press section stability and extend press felt service life.
