Forming fabric can be divided into single layer, double layer, double and a half layer and three layer. The structure of our double-layer forming fabrics is generally a double-layer weft structure; the manufacturing method is the seamed (H) [type]. Compared to single-layer, warp and weft densities are higher. 

Double-layer is more dimensionally stable but less stretchable. Diameters and material types of sheet-side and machine-side wefts can be selected independently, enabling improvements in wire mark, flatness, two-sidedness, 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, it can help improve retention and prevents lint.

4-shed
Used primarily for cylinder machines in pulp mills. Lessens stretching and wire marks.

7-shed
Excellent surface properties providing good fabric surface smoothness. Suitable for paper with wire mark difficulties.

8-shed
Provides excellent drainage and abrasion resistance properties.

16-shed
Has the best drainage and abrasion resistance among our double-layer designs.
