The polyester forming fabric on paper machine shows great effect on the forming of the fibre mat into a uniform and consistent web of fibres. The polyester forming fabric designed to support the fibrous suspension and assist with the drainage of the stock suspension as a finely woven fabric . They are classified into 2 or 3 layers by surface structure and by open area. Normally they  have a finer mesh on the top of the structure with a coarse supportive mesh on the non-paper side.

During the forming process polyester forming fabric allows the water to pass through the voids between the filament weaves of the wire while the fibre forms a mat on top of the Forming Fabric. The  polyester forming fabric is a continuous belt which allows the water to be drained evenly through the fabric while forming a fibrous mat, as well as it transfers the web over the forming area (Forming Table) as part of the continuous paper making process. It design will influence the sheet formation. The polyester forming fabric open area, the number of layers used in the fabric structure and the size of the filaments used will determine the drainage rate and the size of the fibrous and filler particles which are maintained within the sheet (Web) structure (Retention).

It is necessary to clean polyester  forming fabrics for maintain their drainage properties. Traditionally Forming Fabrics were made from Bronze wire, interwoven to the correct mesh dependant on the grade to be produced, now the Forming Fabrics are made from a combination of Polyester and other synthetic materials interwoven into single double and triple layered fabrics.
