Quanzhou Zhiyue Biotechnology Co., Ltd: Innovating Meltblown Nonwoven Solutions In China
As the global demand for high-performance filtration and barrier materials surges, Quanzhou Zhiyue Biotechnology Co., Ltd has solidified its position as a trusted manufacturer of meltblown nonwoven fabrics in China. Leveraging advanced polymer science and precision engineering, the company caters to industries where micron-level filtration and material integrity are non-negotiable.
Meltblown Technology: Precision At Microscale
Meltblown nonwovens are produced by extruding molten polymers through fine nozzles, creating ultrafine fibers (1–5 µm diameter) that self-bond into a dense, porous matrix. Key advantages include:
Superior Filtration Efficiency: Captures particles as small as 0.1 µm.
High Surface Area: Ideal for adsorption applications (e.g., oil, chemicals).
Customizable Porosity: Adjustable pore size (10–100 µm) for targeted performance.

FAQ: Meltblown-Specific Insights
Q1: How do you maintain electrostatic charge stability over time?
A: Our in-house electret treatment uses corona charging with UV stabilizers, ensuring >95% charge retention after 5 years of shelf life.
Q2: Can you produce meltblown fabrics with antiviral properties?
A: Yes. We offer fabrics treated with CuO nanoparticles or quaternary ammonium salts, achieving >99% viral reduction (tested per ISO 18184).
Q3: What is your monthly production capacity?
A: Current capacity is 1,200 tons/month, scalable to 2,000 tons with 60-day notice.
Q4: Do you provide meltblown composites (e.g., SMS) for surgical gowns?
A: Yes. Our SMS (Spunbond-Meltblown-Spunbond) fabrics meet AAMI Level 3/4 standards with hydrostatic pressure resistance up to 50 cmH₂O.
Q5: How do you ensure consistency in fiber diameter?
A: AI-controlled extrusion systems monitor melt temperature (±1°C) and airflow (±0.5 m/s) in real time, ensuring micron-level uniformity.
Q6: Are your PLA meltblown fabrics compatible with ultrasonic sealing?
A: Absolutely. Our bio-based PLA grades have a melting point of 160–170°C, suitable for high-speed ultrasonic bonding.
