This article explains in detail the reasons for the decrease in forming fabric tension, analyzing the influence of factors such as paper machine speed, dewatering, vibration control, and fabric structure.
This article introduces paper making felt types based on their positions, explaining the functions of wet felts and dry felts in paper production.
Paper making felt linting and wear can affect paper quality and machine performance. Sun Hong explained the main causes, including mechanical damage, chemical effects, and improper operation, and provides practical solutions to reduce fiber shedding, improve wear resistance, and extend felt service life.
Paper making felt permeability testing is essential for evaluating felt condition, optimizing dewatering performance, and ensuring stable paper machine operation. Learn the purpose, methods, and benefits of permeability testing, including trend analysis, fault diagnosis, and efficiency improvement in the press section.
Sun Hong introduce outlines the development history, material innovations, and structural advantages of different types of paper making felt, highlighting their role in improving dewatering performance, durability, and efficiency in modern paper machines.
Choosing the right forming fabric depends on machine type, pulp characteristics, and fabric structure. Sun Hong outlines key selection criteria to ensure stable operation and consistent paper quality.
The performance of press felt directly affects the efficiency and output of paper machine. Explains how press felt contributes to moisture removal, sheet support, pressure balance, and surface formation in the press section.
Dryer felt is essential for heat transfer, moisture removal, and paper web stability in the dryer section of paper machines. Sun Hong explains its working functions, application roles, and key selection considerations such as durability, dimensional stability, breathability, and surface properties to ensure efficient drying and high-quality paper production.
The MG felt is used on the MG cylinder, it’s a special top felt for press section. It’s mainly as the top paper making felt for support roll press. It play an important role for paper forming and drying process.
Paper making felt selection is closely related to operating parameters of the paper machine, including line pressure, vacuum level, pulp characteristics, and washing conditions. The paper making felt structure, strength, and permeability, providing a practical basis for matching felt performance with process requirements to achieve stable operation and extended service life.
