In many applications, the release of the dust cake from the fabric surface is enhanced by heat treatment of the fabric face. The adhesive forces between the fabric and the dust cake are greatly reduced by this process.
In some application the back side of the fabric is also heat treated to reduce the wear of the fabric, where it comes to contact with the wire support cage of the filter cartridge. This treatment results in longer filter life.
Our synthetic fabrics are also manufactured with a special baked-on deep texture on the fabric back surface. The texture pattern is such to reduce wear of the fabric where the fabric comes into contact with the wire support cage of the filter cartridge. This proprietary process was developed together with the Textile Research Institute in Brno in 1992. It extends the fabric life by as much 50 to 100%.
