From the core of masks to the nemesis of oil pollution, a comprehensive article on meltblown nonwovens
- 2025-06-06
I. What is meltblown nonwoven fabric?
Meltblown nonwoven fabric is a fiber web made of polypropylene (PP) as raw material, through high-temperature melting, ultra-fine airflow blowing, electrostatic charging and other processes. Its core characteristics:
The fiber diameter is only 0.5-10 microns (1/100 of human hair)
Three-dimensional interlaced mesh structure (1cm² contains millions of fibers)
With permanent electrostatic field (powered by electrostatic electret technology)
The essential difference from traditional textiles:
No spinning or weaving is required, and functional materials are formed directly through physical combination
II. Manufacturing secrets: Four-step molding full analysis
1. High temperature melting
→ Polypropylene pellets melt at 260℃ into a viscous flow state
2. Airflow blowing
→ 0.5MPa high-pressure hot air stretches the polymer
→ Forming ultrafine fiber flow (key process)
3. Electrostatic implantation
→ 30,000 volt high-voltage electric field makes the fiber charged
4. Netting and rolling
→ Fiber self-weight interweaving + electrostatic adsorption shaping
Technical breakthrough:
Sooner double S electret process improves charge stability by 300% (compared with the industry average)

V. Selection guide: three core parameters
1. Gram weight (gsm)
30-50gsm: light adsorption ▫ 80-100gsm: heavy oil cleaning
2. Fiber fineness
＜2μm: precision filtration ▫ 5-10μm: Economical and general purpose
3. Electret process
Grade A: Static electricity retention > 3 years (Soonercleaning patent)
Future track of meltblown cloth

Smart response:
Thermosensitive color-changing meltblown cloth (visual warning of oil saturation)
Industry insights:
"When new energy vehicles explode, the demand for electrolyte-resistant meltblown cloth surges by 300% - this is a new battlefield for material evolution"
Answers to common misunderstandings
Q: The thicker the meltblown cloth, the better?
A: Wrong!
Adsorption efficiency = fiber fineness + static electricity, Soonercleaning 50gsm product oil absorption is better than traditional 100gsm
Q: Why do industrial-grade meltblown cloths need to be customized in color?
A: Safety management system requirements:
Blue = chemicals Orange = high-risk areas Gray = general oil pollution
