The products specifications of our company：Length：7.5m~~120.00m       Width：8.0m or less        Felt weight:：600g/m2~~2400 g/m2
The excellent products of my company are the BOM composite laminated base fabric papermaking felt.
As it is well known, any kind of base fabric felt is consisted of two parts: base fabric and batt fiber layer. Our company has a variety of basic modules for base fabric and batt fiber layer.
Based fabric modules consist of: regular base fabric (Figure 1), high dehydration and anti-sticky   base fabric (Figure 2), high elasticity base fabric (Figure 3, Figure 4), anti-high line force base fabric, non marking base fabric (caused by the felt surface and the base fabric).

Batt fiber modules consist of: regular fiber layer (Figure 5), high elasticity fiber layer (Figure 6), hairfreeness fiber layer (Figure 7), wear-resistance fiber layer (Figure 8), anti-rewetting fiber layer, ultra-smooth fiber layer (Figure 9), high dehydration fiber layer module (Figure 10), and so on.
   

For the fine paper required high surface quality (i.e. sheet smoothness and non-marking), the upper base fabric layer uses no marking base fabric module, and fine batt fiber uses ultra-smooth fiber layer module in our laminated base fabric felt. So that the pressure distribution in the pressure nip is more uniform when the press felt pass through the press nip (Figure 11 illustrates press felt assembled no marking base fabric module; Figure 12 illustrates Press felt assembled regular base fabric module.).
Because of our unique needling technology, the distribution of the batt fiber is more even in the press felt (Figure 13 illustrates press felt assembled ultra-smooth fiber layer module.). Through optimized surface calendaring process (heatsetting process), the surface of the press felt is smoother than the regular felt.

For the press felt required high line force in the press nip, anti-high line force base fabric module is used in the multi-axial laminated base weave felt. Number of layers of the base fabric is determined according to the specific line force and the required void volume of the felt. For the fine paper required high surface quality, the upper base fabric layer uses no marking base fabric module (figure 14 shows double layer base fabric felt, figure 15 shows three layer base fabric felt, figure 16 shows laminated felt assembled no marking base fabric module), and fine batt fiber uses curl high elasticity fiber layer module in the felt. So this type of felt has an excellent compaction resistance.

For the felt required high dewater performance, base fabric layer uses high dehydration and anti-contamination base fabric module (Figure 17), and batt fiber layer uses high dehydration fiber layer module. So this kind of felt has an excellent dewater property (Figure 18).

   
For the felt required forbidding batt fibers in the sheet, fine batt fiber layer uses hairfreeness fiber layer module (figure 19 illustrates partial enlarged drawing of the hairfreeness fiber layer), and coarse batt fiber layer uses wear-resistance fiber layer module. Therefore this kind of felt has an excellent hairfreeness performance (Figure 20 illustrates partial enlarged drawing of the hairfreeness felt).
   

Some paper defects such as felt marking, two-sideness properties of paper surface, shadow marking (caused by grooves in grooved roll, holes in suction, or blind drilled rolls), can be canceled through reasonable configuration different base fabric modules and batt fiber layer modules. Through reasonable configuration different base fabric modules and batt fiber layer modules will enable our press felt having different advantages as following: fast start up, removing vibration in press nip, non sheet stealing, stable running, high sheet dryness, or long running life.
The superiority of the laminated base fabric papermaking felt is that various type of papermaking felt that having different characteristics can be obtained by reasonable configuration different base fabric modules and batt fiber layer modules. These various types of felt are suitable for different situations, such as common press felt, large diameter roll press felt, shoe press felt, pulp board press felt, dryer felt, and so on. They can meet requirements of almost all kinds of paper in paper industry, such as cultural paper, packaging paper, tissue, specialty paper.
For satisfying different customers’ requirements, we design and produce papermaking felt according to the “tailor design conception” truly.
