Performance Summary
Filtration Performance
The fine-fiber meltblown structure balances airflow and particulate capture efficiency, making it suitable for mask filter layers, HVAC filtration systems, and industrial air filtration products.
Oil Absorption Capability
The oleophilic polypropylene microstructure rapidly absorbs hydrocarbons and oils, supporting effective spill control and industrial maintenance applications.
Low-Lint Wiping Performance
Plum-blossom embossing enhances fiber cohesion, minimizes lint release, and improves contact with surfaces during cleaning and wiping operations.
Converting Stability
Consistent GSM and tensile strength support efficient slitting, die-cutting, laminating, ultrasonic welding, and automated converting processes.
Quality Assurance (QA)
Incoming Material Inspection
Polypropylene resin is verified through supplier traceability and incoming material quality checks.
In-Process Manufacturing Control
Continuous in-line monitoring ensures stable web formation, uniformity, and accurate basis-weight control throughout production.
Final Product Inspection
Each roll undergoes testing for:
Basis weight
Thickness
Breaking strength
Absorbency performance

Frequently Asked Questions (FAQ)
Q: What is the absorbency performance?
Measured absorbency results include:
Liquid absorbency capacity: 2.5 ml/g
Absorbency speed: ≥25 mm / 30 seconds
Q: Is the material oleophilic or hydrophobic?
The meltblown polypropylene web is:
Oleophilic toward hydrocarbons and oils
Hydrophobic toward water
This makes it highly effective for oil-absorbent wipes and spill control applications.
Q: What quality control systems are used?
Quality control includes:
- Incoming resin verification
- In-line basis weight monitoring
- Final roll testing
- Batch traceability management
Q: What is the production capacity?
Current production capability is approximately:
0.8–1.2 tonnes per day
Lead times vary based on order size and customization requirements.
Q: Is this suitable for mask filtration applications?
Yes. The fine-fiber matrix supports balanced airflow and particle capture performance suitable for mask and respirator filtration layers.
Final filtration performance depends on multilayer structure and electret treatment.
Q: How should the material be stored?
Store in:Cool, dry environments.Original packaging.Areas protected from direct sunlight and humidity.
Q: Can tighter GSM and tensile tolerances be manufactured?
Yes. Weston Nonwoven can manufacture tighter tolerance specifications for qualified projects and OEM production programs.For application guidance, testing support, or technical consultation, contact:info@westonmanufacturing.com
