Dryer Fabric Maintenance: Extend Service Life by 30%

Why Dryer Fabric Maintenance Matters

Dryer fabrics represent a significant operating cost for paper mills. Proper maintenance can extend fabric life by 30% or more, directly impacting profitability through reduced downtime and replacement costs.

Daily Inspection Checklist

Visual Inspection:

• Check for edge wear and fraying
• Inspect seam integrity
• Look for contaminant buildup
• Verify fabric tracking alignment

Tension Monitoring:

• Record running tension daily
• Compare against baseline tension from installation
• Adjust tension within manufacturer specifications

Cleaning Methods

Chemical Cleaning:

• Use pH-neutral cleaners for routine maintenance
• Use solvent-based cleaners for pitch and stickies
• Avoid strong alkaline cleaners on hydrolysis-sensitive materials

High-Pressure Showering:

• Schedule during planned downtime
• Maintain minimum 30 cm distance from fabric
• Use fan nozzles for uniform coverage

Edge Wear Prevention

Edge wear is the leading cause of premature dryer fabric failure:

1. Verify roll alignment every 3 months
2. Install edge guards in high-temperature sections
3. Monitor felt roll bearing temperatures
4. Address edge curling early before cracking develops
