The structure of triple layer forming fabric SSB

The structure of triple layer forming fabric SSB permits to design the forming side and the wear side of the fabric independently to achieve better performance. The bottom side is made with large diameter yarns to improve stability and wear resistance.

The sheet side has fine yarns to optimize the sheet forming characteristics of the fabric. The fine mesh on top supply a better sheet support, improving formation, increasing fiber retention and reducing two sideness. Triple layer forming fabrics SSB are used in the production of almost all paper grades, mainly in printing & writing papers and kraft papers grades.

Triple layer forming fabrics SSB are woven in 16, 20 or 24 shaft patterns. The paper side is woven in 1×1 plain weave pattern and made by fine polyester mono filament to achieve excellent paper web formation and increased fiber retention while the machine side is woven in 5 or 6 shaft with large diameter mono filaments for high wear resistance, which contributes to the outstanding drainage.

Benefits of triple layer forming fabrics
For paper and board grades that require excellent printability.
Excellent formation and fiber support.
No fabric marking.
Easy to clean.
High structural stability and wear resistance.

Paper machine clothing: Forming, Drying and Pressing

Paper machine clothing are used in the whole paper making process to help to make paper, including forming, pressing, drying process.

Forming:

A sheet of paper begins in the forming section, and in this section, a mixture of 99% water and 1% cellulose fiber is introduced evenly across a forming fabric. Thereby the polyester forming fabric acts as both a sheet conveyor and a dewatering device.

Pressing:

In this section, additional water is mechanically removed from the newly formed sheet and the sheet is carried continuously by a large press fabric between two rolls, where our press felt acts as a sheet conveyor and a press filter belt.

Drying:

In the dryer section, the paper sheet travels around large diameter heated cylinders, where the balance of the water is removed by evaporation. Polyester dryer fabrics hold the sheet tightly in contact with the cylinders through the dryer section.
