With Voith Paper’s E-Flex fabrics, a breakthrough has been achieved in the design structure of press fabrics. Paper mills which installed E-Flex achieved fast machine start-ups, higher nip dewatering values, and better paper quality.

It’s a matter of structurally optimized fabrics that influence fabric characteristics through targeted placement of polymer particles. The pressure transmission in the nip is homogenized. In addition, the polymer structure provides improved resilience of the press fabric and thus stable dewatering characteristics over the entire running time.

Flow resistance is reduced in the Z direction due to optimally set pore volume and the water can flow more rapidly through the fabric, into the grooves of the cover.

A further advantage is the improved abrasion resistance of the paper and the roll side of the fabric.

All Voith’s press fabrics that have the special-ly developed polymer structure come under the family name of E-Flex.

The structural optimization with polymers can be worked into the various levels of the press fabric, depending on which characteristics need to be optimized. Structural optimization of the papermaking surface optimizes the start-up behavior and gives an improved paper and board surface.
