Reasonable Use of Alkali and Acid Washing for Press Felts
Press felt cleaning is crucial for dewatering efficiency, paper quality, and the life of the press felt itself. The main cause of the contamination is blockage by fiber fillers, slurry, resin and other impurities. Appropriate alkaline and acid washing can remove deposits and improve the dewatering efficiency of press felt.
How to Avoid the Wear of Press Felt
During the production process of press felt, the paper materials contain fine fibers, fillers, rubber and other substances, and some impurities in the production water are very easy to adhere to the press felt, blocking the holes of the press felt and affecting the absorption and water filtration performance of the press felt. Therefore, washing … How to Avoid the Wear of Press Felt
What are The Dactors That affect the Stability of Press Felt?

Causes and Solutions for Vibration of Seamed Press Felt in paper production
Sun Hong’s seamed press felt enable quick and convenient installation. This article explores the causes of the vibration and provides you with solutions, enabling faster and more stable paper machine operation.
The relationship between the press felt and the wet end of the paper machine and how to solve it?
The press section is the most likely location for impression to appear in the paper production process. Generally speaking, the dryness of the paper exiting section is between 18% and 22%. The wetter the paper is in the press section, the easier it is to change the fiber arrangement, causing fiber displacement and causing impression … The relationship between the press felt and the wet end of the paper machine and how to solve it?
What’s the relationship between press felt and paper rewetting?
What is paper rewet? Paper rewetting is a capillary water transfer phenomenon, which can occur even at high speed and with a short residence time in the nip. During the rewetting process, the water in the press felt enters the wet paper, and the water temporarily transferred to the grooves or holes returns to the … What’s the relationship between press felt and paper rewetting?
