CleanWeave Dryer Fabrics

CleanWeave Dryer Fabrics

New thinking in drying

To reach better results in drying efficiency, Voith has developed with CleanWeaveTM a new product range of dryer fabrics. CleanWeave dryer fabrics are characterized by strength, durability and hydrolysis resistance throughout the whole fabric life. They are designed to minimize the build-up of contamination within the fabric structure and to manage the extreme conditions found in a dryer section.

Similar to CleanWeave dryer fabrics, rocks and minerals need to survive in extreme conditions

Strong even under challenging conditions

Many of these characterizations are also attributed to rocks. Similar to CleanWeave dryer fabrics, rocks and minerals need to survive in extreme conditions. This often requires the highest temperature resistance, strength and an ability to maintain porosity. The durability and performance of each dryer fabric and rock is a direct expression of their structure and composition of single elements.

SynStron – Improved yarn material for advanced dryer fabrics

Heat, moisture and the applied pressure in the dryer section are real challenges for standard yarn material.

Voith SynStron material uses a unique material composition that gives Voith dryer fabrics superior tensile strength, as well as higher abrasion and fibrillation resistance. As a result, Voith dryer fabrics are able to withstand the challenging environment in the dryer section and improve drying efficiency.

Dryer fabrics for all applications

Evaporite
Clean and robust dryer fabric

Evaporite is a robust dryer fabric with a single-layer structure and high contamination resistance. The proven combination of flexing points and minimum cross-over points resists the build-up of contamination inside the structure. This ensures effective evaporation of moisture from the sheet through the entire fabric life.

The tight fabric construction enables easy removal of dirt deposits from the surface. This is due to the CleanWeave technology utilized in this single-layer design construction.

EvaporiteHigh
Clean and open dryer fabric

EvaporiteHigh is a robust dryer fabric with a single-layer design and an open structure for applications that require a higher air flow for sheet runnability and evaporation.

EvaporiteHigh is characterized by a minimum number of yarn cross over points in the structure, significantly reducing the potential for fibers to become trapped.
The combination of CleanWeave technology, high sheet contact and the open structure ensures EvaporiteHigh is the best in class for applications where high evaporation is required.

Jade
Clean and lean dryer fabric

Jade is a single-layer dryer fabric with excellent contamination resistance. It provides good contact area, great performance and ease in cleaning. The combination of flat yarns, thin fabric caliper and exceptionally low internal void volume enables easy removal of dirt particles from the surface.

The flat warp structure and high number of contact points grant high sheet control. The interconnected channels allow the stabilizer vacuum to evenly distribute the optimum under pressure and reduce sheet breaks.

Jade High

Lean and open dryer fabric

JadeHigh is a thin dryer fabric with a single layer structure for applications that require a higher air flow for sheet runability and moisture evaporation. The proven concept of fewer cross-overpoints repels the build-up of contamination inside the fabric structure. This guarantees highly effective evaporation of moisture from the sheet throughout the entire fabric life.

The combination of flat yarns, thin fabric caliper and exceptionally low internal void volume allows easy removal of dirt particles from the structure. Extremely open fabric surfaces are great for evaporation. JadeHigh provides a balance between an open structure and high contact points to maximize sheet handling.

Pyrox
Heat-resistant dryer fabric with robust structure

Pyrox is a robust dryer fabric with a single-layer structure and medium to high temperature, as well as abrasion resistance. The combination of durable polyester material and temperature-resistant PPS yarns guarantees good hydrolysis behavior throughout the entire fabric life. Pyrox is made of SynStron yarns, which are developed specifically for these requirements.

Pyrox is suitable for single- or double-tier dryer sections with medium-level steam pressures and can furthermore be installed in latter positions of pre and after dryers. The dryer fabric is applicable for the production of board, packaging papers, and graphic paper grades where both hydrolysis and abrasion need to be addressed.

Your benefits

  • Resistance to abrasion
  • Resistance to hydrolysis
  • Heat transfer
  • Easy cleaning
  • Interaction with cleaning systems
