High-efficiency Filter Element for Nonwoven Industry: Maintenance, Care, and Performance Solutions
In nonwoven fabric manufacturing, the high-efficiency filter element plays a crucial role in ensuring stable polymer melt filtration, consistent fabric quality, and reliable machine performance. By preventing contaminants and impurities from entering the production line, filter elements improve both product durability and efficiency. However, to achieve optimal performance, proper maintenance and regular care are essential. This article provides a comprehensive guide covering maintenance frequency, daily upkeep, professional recommendations, and troubleshooting solutions for filter elements used in nonwoven production lines.
High-efficiency filter elements are designed to:
Remove solid particles, gels, and impurities from polymer melt.
Protect spinnerets, pumps, and extruders from clogging.
Ensure uniform fiber distribution during web formation.
Reduce downtime caused by frequent replacements or machine stoppages.
Improve the overall service life of critical production components.
With advancements in material technology, modern filter elements are manufactured with stainless steel wire mesh, sintered fiber felt, or multilayer woven materials, offering enhanced filtration accuracy and high-temperature resistance.
Proper maintenance schedules ensure that filter elements continue to deliver high-performance filtration. The frequency depends on factors such as raw material quality, machine operating hours, and production capacity.
| Production Condition | Recommended Maintenance Frequency | Notes |
|---|---|---|
| Standard PP/PE nonwoven production | Every 200–300 operating hours | Clean or replace depending on pressure drop |
| High-temperature PET/PA6 nonwoven lines | Every 150–200 operating hours | Higher melt viscosity accelerates clogging |
| Continuous 24/7 production | Weekly inspection, monthly cleaning | Prevent sudden line shutdowns |
| Recycled polymer application | Every 100–150 operating hours | Recycled material often has higher impurities |
Tip: Monitor differential pressure across the filter element. If pressure rises beyond set tolerance, cleaning or replacement is required immediately.
Backflushing: Use controlled reverse-flow pressure to remove trapped particles.
Ultrasonic Cleaning: Effective for fine stainless steel mesh filters.
Thermal Cleaning: Burn off polymer residues in a controlled furnace (suitable for sintered filters).
Solvent Cleaning: For polymer types that dissolve in specialized cleaning agents.
Avoid mechanical shock to prevent deformation of the filter screen.
Do not use sharp tools for scraping residues.
Always dry filters thoroughly before reinstallation.
✅ Inspect pressure gauges before each shift.
✅ Check sealing integrity to prevent polymer leakage.
✅ Record differential pressure readings for predictive maintenance.
✅ Ensure spare filters are available to minimize downtime.
Store in clean, dry, and well-ventilated environments.
Protect against dust, moisture, and direct sunlight.
Keep replacement filter elements in original packaging until installation.
Develop a rotational schedule for filter element replacement.
Establish a predictive maintenance plan using sensor monitoring.
Train operators on safe handling and correct installation procedures.
| Problem | Possible Cause | Solution |
|---|---|---|
| High differential pressure | Clogged filter due to impurities | Perform backflush or replace filter |
| Polymer leakage | Worn sealing strip or gasket | Replace sealing components |
| Reduced filtration efficiency | Filter damaged or incorrect mesh size | Install correct specification filter element |
| Frequent clogging | Low-quality raw materials | Use pre-filtration system or higher-grade filter element |
