2.5 Layer forming fabric
Features:
1.Low permeability, smooth surface fabrics with very high contact area;
2.Very high contact area for improved drying;
3.Smooth surface for improved sheet quality;
4.Heat-resistance, high temperature resistance(180 degree);
5.Shrink-resistant,wear resistance, acid and alkali-resistant;
6.High dimensional and diagonal stability, good air ventilation.
Usage of Different Types of Wire Mesh:

| Eight heddle monolayer forming net | suitable for making high grammage paper, like paper bag paper, kraft paper, lineboard, corrugated paper, cardboard paper, etc. |
| Seven heddle double-layer forming net | suitable for making high-grade printing paper, tissue paper and so on. |
| Eight heddle double-layer forming net | suitable for making high-grade printing paper, offset printing paper, tissue paper and top and medium layer pulp of board paper and so on. |
| Eight and sixteen 2.5 layer forming net | suitable for making high-speed paper machine, producing various types of paper |
Technical Process
16-shed double and a half layer polyester forming fabric :
On the basis of double layer , it use 8- shed attached supporting weft as weaving type clinging to paper surface, thus it can increase the retention rate of fiber and filler ,it use thick diameter monofilament as bottom weft clinging to paper machine and use the manner of 16-shed as one group longspan double warp press weft ,then it increase the stiffness of the fabric and bowedweft of bottom weft and increase contact surface for fabric and dewatering clements for paper machine. It mainly run on medium-high speed machines,and has flat structure surface with stable performance and long service life potential etc. Apply on these paper grades,such as corrugated paper,Kraft-liner paper, Coated duplex board and so on.
