Such types of spiral dryer fabrics for belt press filter are stuffed with filler mono-filaments in the spiral loops to reduce the permeability. These spiral fabrics are widely used for sludge or sewage dewatering in many industries such as paper mills, effluent treatment plants, mining and mineral industry.
Polyester plain fabric is also called polyester linear screen cloth. The 2 and 3 shaft weaving design are mainly used in paper pulp making, packaging and linear cardboard making etc.
These dryer fabrics or screens are made of rectangular hydrolysis resistant mono-filaments which ensure optimum economic life time. And the rectangular shape of yarns provide improved runnability, sheet handling and wear potential.
In the process of paper making, most of the energy saving is related to improving the energy efficiency of the drying process and the utilization of the waste heat. In general, pulp and paper energy costs accounted for about 10% to 35% of the cost of production; consumption of vacuum consumption accounted for 15% of paper electric power consumption to 18%, most of the vacuum energy is supplied to the vacuum roller, suction tank and vacuum suction tank; drying is the highest part of energy consumption in the production of paper. The key factor to reduce the energy consumption is to increase the dry degree of paper after press. Continue reading “Energy saving in paper making process”

The Manufacturing Process Of Paper Machine Clothing
Weaving – Seaming-Heat setting
The structure of triple layer forming fabric SSB permits to design the forming side and the wear side of the fabric independently to achieve better performance. The bottom side is made with large diameter yarns to improve stability and wear resistance.
The sheet side has fine yarns to optimize the sheet forming characteristics of the fabric. The fine mesh on top supply a better sheet support, improving formation, increasing fiber retention and reducing two sideness. Triple layer forming fabrics SSB are used in the production of almost all paper grades, mainly in printing & writing papers and kraft papers grades.
Triple layer forming fabrics SSB are woven in 16, 20 or 24 shaft patterns. The paper side is woven in 1×1 plain weave pattern and made by fine polyester mono filament to achieve excellent paper web formation and increased fiber retention while the machine side is woven in 5 or 6 shaft with large diameter mono filaments for high wear resistance, which contributes to the outstanding drainage.
Benefits of triple layer forming fabrics
For paper and board grades that require excellent printability.
Excellent formation and fiber support.
No fabric marking.
Easy to clean.
High structural stability and wear resistance.
