Triple layer forming fabrics with ssb design are now widely employed for all paper grades, from tissue through writing & printing to board and packaging paper. The SSB design gives superior performance. The paper side is woven in 1x1 plain weave pattern with fine polyester monofilaments to achieve excellent paper sheet formation and increased fiber retention.
2.5 layer forming fabric is a standard double layer forming fabric with an additional weft yarn on the sheet side for an an improvement in sheet formation, smoothness, reduction of wire mark and better cleaning of the showers.
A single layer forming fabric has the simplest weave pattern. Single layer fabrics have one layer of warp yarns and one layer of weft yarns. And single layer forming fabrics are also applied in the manufacturing of multi-layer forming fabrics due to their good paper sheet forming properties.
