What is paper machine clothing?

Date Issued：2022-06-11

Paper machine clothing is a key component in the papermaking process of forming, drying, and conveying the sheet. These fabrics are technically sophisticated, custom-designed engineered belts manufactured from monofilament and synthetic fiber materials imported from Perlon and Monosuisse. Depending on the use position, it can be divided into the following three categories: forming fabric, press felt, and dryer screen.

Forming fabric is used in the forming section to make the paper sheet. It works as a conveyor and a dewatering device. When the fabric moves to the press section, water drains through it. The forming fabric can last from 1 to 6 months depending on the pulp quality and working environment.

The press felt plays an important role in removing the water from the paper web after the forming section, and at the same time imparting smoothness and conveying it to the dryer section. The press felt needs to reduce the moisture of content of the paper sheet from 3% to 1%. For this reason, the press felt should provide the following functions: water removal, smoothness, and runnability.

The dryer screen is an engineered paper machine clothing used to hold the sheet in close contact with the cylinders through the dryer section. It could be divided into spiral dryer screens and woven dryer screens by using different weave types. Both types can use round monofilament or flat monofilament to meet different paper production requests. It can last much more than forming fabric from 6 to 18 months.
