Product Overview
Liquid Filtration PET Nonwoven Fabric is engineered from 100% premium polyester (PET) fibers utilizing advanced spunbond or thermal bonding technologies. Specifically designed for critical and heavy-duty liquid-solid separation, it delivers an optimal balance of high tensile strength, outstanding chemical compatibility, and exceptional thermal stability, ensuring consistent and reliable filtration performance under harsh industrial conditions.
Key Features
High Tensile & Burst Strength: Resists high hydraulic pressure and deformation, preventing blowouts during continuous flow.
Precision Micron-Level Filtration: Uniform pore size distribution ensures predictable and repeatable filtration efficiency.
Excellent Thermal & Chemical Resistance: Performs reliably in temperatures up to 120°C and resists chemical corrosion from oils, mild acids, and solvents.
Optimal Pleating Stiffness: Specifically treated for flawless pleating, high stiffness, and zero fiber shedding during processing.
Customizable Surface Treatments: Available with hydrophilic, hydrophobic, or anti-static modifications to suit diverse liquids.
Technical Specifications
Quality Control Notice: We maintain a strict plus/minus 5% tolerance on basis weight and thickness to ensure roll-to-roll consistency for automated filter production lines.

Customization Options
We offer tailored solutions to align perfectly with your exact filtration requirements and machinery specifications:
Mechanical Adjustments: Tailored tensile strength, thickness, and stiffness for optimal converting performance (pleating, bag making, or welding).
Functional Coatings: Specialized hydrophilic or hydrophobic finishes, and anti-static surface modification.
Slitting & Packaging: Precision slitting (minimum width 100mm), customized roll diameters, and core sizes (2-inch or 3-inch).
Quality Control
Quality is our lifeline. Every roll of PET filtration nonwoven fabric undergoes rigorous laboratory testing before leaving our facility. Our QC parameters include: Basis Weight (GSM) Uniformity Testing, Air Permeability Control, Tensile Strength & Elongation Tests, Hydrostatic Head (for hydrophobic types), and Microscopic Pore Size Analysis.
Packaging & Shipping
Standard Export Protection: Wrapped in heavy-duty PE moisture-proof film, followed by optional robust woven bags, custom cartons, or fumigation-free pallets.
Core Protection: Heavy-wall cardboard cores (3-inch or 2-inch) to prevent roll deformation during long-distance maritime transit.
Global Logistics Support: Full support for FOB, CIF, EXW, and DDP terms with seamless customs documentation support.
FAQ
Q: What are the main technical advantages of PET nonwoven over PP nonwoven for liquid filtration?
A: PET (Polyester) offers significantly higher temperature resistance (up to 120°C continuous vs PP's 90°C), superior tensile strength, and better dimensional stability under pressure. It also features higher chemical resistance against organic solvents and oils, making it ideal for harsh industrial environments.
Q: Can you customize the filtration grade and pore size for specific microns?
A: Yes. By adjusting the fiber fineness, blending ratio, and thermal bonding pressure, we can fine-tune the pore structure to achieve specific micron ratings ranging from 1 micron to 100 microns.
Q: Do you offer free sample rolls for laboratory and machine trial tests?
A: Absolutely. We understand that filtration media requires qualification. We provide free A4-size sample sheets or small sample rolls (within 5 to 10 meters) for your thickness, permeability, and pleating trials. Buyers only cover the courier cost, which is fully refundable upon the first bulk order.
Q: What is your standard lead time and Minimum Order Quantity (MOQ)?
A: Our standard MOQ for customized gsm or width is 1,000 kg per specification. For stock specifications, there is no strict MOQ. The delivery time typically ranges from 14 to 21 days after deposit confirmation, depending on the volume and customization complexity.
