Filtration Advantages of Melt Filter Cartridges in Spunbond Nonwoven Production Lines
Melt candle filter cartridges are widely used on pp spunbond nonwoven production lines. The primary function of the melt candle filter is going to filter impurities and particles from the polypropylene pellets. The melt candle filter has two filtration chambers, each filtration chamber could fix 9 to 13 pieces of melt filter cartridges. These candle filter cartridges raw material is pleated full stainless steel Filter Mesh, typically with a filtration precision ranging from 120 mesh to 150 mesh. The pleated design of the filter mesh significantly increases the filtration surface area, thereby enhancing filtration efficiency. This melt candle filter cartridge design prolongs the filtration service life on pp spunbond nonwoven production lines. Furthermore, the melt filter cartridges designed based on quick-installation mechanism and can be repeatedly cleaned, reducing production costs for pp spunbond nonwoven fabric production.
Filtration Advantages of Melt Filter Cartridges in Spunbond Nonwoven Production Lines
1.Enhanced Purity
Effectively removes impurities (>99.9% capture rate) from polymer melts
Ensures consistent fiber formation and defect-free web formation
2.High-Flow Efficiency
Pleated design provides 3-5× greater filtration area than standard screens
Maintains optimal melt pressure (typically <15% pressure drop increase)
3.Precision Filtration
120-150 mesh options target sub-40μm contaminants
Prevents spinneret clogging and fiber breakage
4.Extended Service Life
Vertical cartridge configuration allows 30-50% longer runtime
Reduces changeover frequency by 40% compared to planar filters
6.Production Stability
Stabilizes extrusion pressure (±0.5% variance)
Enables continuous operation >600 hours per cycle
7.Cost Efficiency
Reusable design withstands 15+ cleaning cycles
Quick-change system minimizes downtime (<10 minutes per cartridge)
8.Quality Assurance
Eliminates "shot" defects in final nonwoven products
Maintains fabric basis weight consistency (CV <1.5%)
