Commonly known as 2.5-layer forming fabric, extra support double layer forming fabrics are to further improve the characteristics of double-layer design. It's a standard double layer forming fabric with an additional weft yarn on the paper side of the fabric. There is an improvement in paper sheet formation, smoothness, reduction of wire mark and better cleaning of the showers. Extra support double layer forming fabrics for paper making are commonly used in newsprint and fine papers production or in applications that use very short fibers.


8-shed extra support weave
- Smooth surface
- Excellent fiber support and formation
- Stable structure and less elongation
- High resistance to abrasion


Applications
- Specialty papers
- Tissue papers


16-shed extra support weave
- High drainage capability
- Large diameter weft yarns on the wear side to provide high abrasion resistance
- Stable runnability


Applications
- Kraft papers, corrugating papers, board papers
Polyester 2.5 layer forming fabrics can be woven in 8, 16 or 24 shed patterns. The weave design offers a uniform distribution of pulp fibers and provides outstanding drainage capacity as a result of high top surface open area. The large diameter of weft yarns and long crimp on machine side provides excellent wear resistance and runability. The 2.5 layer forming fabric has the features of excellent pulp fiber support, paper sheet formation and high drainage.
