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.

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.

An overview of flocking dryer fabric covering its composite structure, types, and production methods, with insights into how it enhances drying efficiency, durability, and paper surface quality in modern paper machines.

About mechanical cleaning methods for press felt, detailing key equipment such as shower systems, beaters, and vacuum boxes, and their roles in improving cleanliness, permeability, and machine efficiency.
