Product Overview
Ultra-Fine Fiber Meltblown Nonwoven Fabric is a high-performance material manufactured through an advanced meltblown process using premium polypropylene (PP) resin or customized functional polymer materials. Featuring a dense three-dimensional microfiber network with fiber diameters ranging from 1 to 5 microns, this fabric delivers exceptional filtration efficiency, excellent barrier performance, low air resistance, and superior skin-friendly softness.
It serves as the core functional layer for medical protective products, industrial air/liquid filtration systems, HVAC filters, automotive cabin filtration, battery separators, and various functional laminates.
As an ISO-certified nonwoven fabric manufacturer and exporter, we provide tailored manufacturing solutions, offering flexible customizations in weight (GSM), width, color, filtration efficiency, and functional treatments to meet stringent global industrial standards.
Main Features
Ultra-Fine Fiber Structure: Microfiber diameter as low as 1–5 microns creates a dense fiber web with superior sub-micron particle capture capability.
Exceptional Filtration & Low Resistance: Engineered to achieve high filtration efficiency (BFE/PFE/VFE) while maintaining optimal air permeability and low pressure drop.
Advanced Electret Treatment: Utilizes premium electret masterbatch and advanced charging technology to ensure long-lasting electrostatic adsorption and stable filtration performance over time.
Uniform Web Structure: State-of-the-art production lines ensure consistent weight (GSM) and thickness distribution, eliminating weak spots.
Multi-Functional Customization: Supports advanced finishes including Hydrophobic, Hydrophilic, Flame-Retardant (FR), Antistatic, Antibacterial, and UV-resistant treatments.
Safe & Eco-Friendly: Non-toxic, odorless, and compliant with international environmental and safety standards such as RoHS and REACH.

FAQ
Q: Can you provide free samples for testing?
A: Yes. We offer free roll or sheet samples (typically 1–5 meters) for your laboratory evaluation or machine trialing. The buyer only covers the international courier cost, which is fully credited back upon your first formal order.
Q: How do you guarantee the filtration efficiency remains stable during long-distance shipping?
A: We use advanced electret masterbatches and specialized high-voltage corona charging equipment. Combined with our multi-layer moisture-proof packaging, the electrostatic charge remains stable for over 2–3 years under proper storage conditions.
Q: What testing equipment do you use to verify filtration data?
A: Our quality control department utilizes the TSI 8130A Automated Filter Tester-the global gold standard for respirator testing-to measure both salt and oil aerosol filtration efficiency and pressure drop.
Q: What is your standard lead time for a container order?
A: Generally, it takes 7–10 days for a 20ft container and 12–15 days for a 40ft HQ container after order confirmation and deposit receipt.
