Forming wire is an important equipment on paper machine. It is a device for forming and dewatering paper on paper machine. It dehydrates
Double layer forming fabric usually means that the weft yarn has a double-layer structure. Compared with single layer forming fabric, double layer warp and weft have higher density, strong stability, but less stretchable.
According to their weaving shed,It includes two different forms: 8-shed and 16-shed.
Structure
The structure of double-layer forming fabrics is a generally double-layer weft structure; the manufacturing method is the seamed type. Compared to single-layer, densities of warp and weft are higher. Double-layer is more dimensionally stable but less stretchable. Diameters and material types, for weft of sheet-side and machine-side, can be selected independently, enabling improvements in wire mark, two-sidedness, flatness, and fabric life. Thanks to the large three-dimensional space , our double-layer also provides excellent drainage property. Drainage force does not directly affect the paper layer, which helps improve retention and prevents fiber.
Advantages
Fine paper sheet surface giving high fiber support.
Improved forming and retention.
Improved fabric service life.
Good dimensional stability and stretching resistance.
Application
The double layer has higher warp and weft density making it more stable than the single layer. That said the double layer is less stretchable. It suitable for various paper machines,such as paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper,etc.
8-shed double layer fabric is suitable for producing quality printing paper. For example ,dictionary paper, offset printing paper,
newsprint and wrap paper. It can be used for tissue paper making and the surface pulp, lining pulp, core pulp and bottom pulp
of the board paper etc. Suitable for medium and high speed paper making machine.
16-shed double and a half layer polyester forming fabric is suitable for producing quality printing paper, such as offset printing paper,
copper plate paper, newsprint and cigarette paper series (wrap paper and filter tips paper), Also is could be used for producing toilet
paper, tissue paper and surface pulp, lining pulp, core pulp and bottom pulp of the board paper etc. Suitable for medium and high speed
paper making machine.
