Valmet has introduced the new generation polarised forming fabrics, revolutionising water drainage in the wire section. Forming fabrics have an essential role in water drainage in the wire section of a paper machine. Polarised structure of the forming fabrics improves machine runnability and performance, taking customer satisfaction to an excellent level.
"Our polarised forming fabrics have been piloted in paper-machines for over a year now. After the polarised technology entered the market in 2016, we have seen its advantages through our customers' performance. The machines run cleaner, number of breaks is reduced, retention is higher, just to mention a few. The unique polarised structure makes a big difference in the fabric performance compared to what we have seen before," says Pekka Kortelainen, product technology manager at Valmet.Valmet has introduced the new generation polarised forming fabrics, revolutionising water drainage in the wire section.

Traditionally, all SSB (sheet support binding) fabrics have had direct drainage channels. In the polarised structure, the machine direction yarns on both the paper side and the roll side are shifted to form an off-stacked structure. This special structure removes the direct drainage channels traditionally used in forming fabrics.
"The unique polarised structure allows controlled initial drainage in the paper-making process. That improves retention and helps keeping the machine clean. Good runnability and cleanliness reduce breaks and therefore increase production capacity remarkably. Cost-savings are created by for example being able to use less chemicals," explains Kortelainen.
To this date Valmet has sold about 300 polarised Valmet Forming Fabrics and over 90 per cent of the customers who have tested the new fabric type have seen its benefits and continued to run it on their machines.
"Our target was to further improve formation without losing our good dewatering, and already the first trials proved the advantages of the polarised structures. We were able to significantly improve formation as we wanted, but the cleanliness and runnability were also good, and the dry content remained excellent. Since that first trial, those polarised fabrics have become our standard Valmet design fabrics. Valmet has been Parenco's key partner in paper machine clothing for over 30 years, and we truly appreciate their support and excellent services," says Yan Vassart, operations manager at Parenco in Netherlands.
The polarised structure can be utilised in all SSB forming fabric types, which makes it suitable for all paper machines. (SV)
