Product Introduction
Industrial PET Nonwoven Fabric (also known as polyester spunbond fleece) is a high-performance continuous filament material engineered for demanding industrial applications. Manufactured from 100% virgin polyester (PET) resin through advanced spunbond and hot-rolling technologies, it delivers exceptional tensile strength, dimensional stability, and long-term durability under extreme conditions.
Compared to standard polypropylene (PP) nonwoven fabrics, PET nonwovens offer superior mechanical properties, significantly higher operating temperatures, excellent UV stability, and outstanding aging resistance. This makes it the premier choice for critical industries including high-temperature filtration, construction waterproofing, automotive interiors, geotextiles, and composite reinforcements.
As a dedicated manufacturer, we provide comprehensive manufacturing customization. We offer tailor-made solutions in weight (GSM), width, color, mechanical strength, and functional surface treatments to perfectly align with your global production requirements.

Product Features
High Tensile and Tear Strength: Continuous PET filaments provide an excellent strength-to-weight ratio, preventing deformation under high-tension industrial processing.
Superior Thermal Stability: Maintains structural and dimensional stability under continuous heat up to 150 Degrees Celsius without shrinking.
Excellent Chemical Resistance: Highly resistant to acids, alkalis, organic solvents, and industrial oils.
Advanced UV and Aging Resistance: Naturally superior to PP in outdoor environments; lifespan can be further extended via customized UV stabilizers.
Optimal Air Permeability: Delivers reliable airflow and liquid filtration properties while maintaining strict structural integrity.
Eco-Friendly and Sustainable: 100% recyclable polyester, supporting international sustainability standards for green supply chains.
Industrial Applications and Solutions
Industrial Filtration (Air and Liquid): Used as support media for pleated air filters, hydraulic oils, and dust collector bags. Solves the problem of filter media collapsing under high temperature and chemical exposure.
Roofing and Building Construction: Ideal carrier for bitumen waterproof membranes and house wrap insulation. Prevents structural tearing and degradation caused by extreme weather and thermal movement.
Automotive Engineering: Engineered for tufted carpet backings, headliners, acoustic insulation panels, and parcel shelves. Meets low-VOC emission and flame-retardant automotive standards.
Geotextiles and Civil Engineering: Utilized in road building, railway foundations, and drainage systems. Provides excellent soil separation, reinforcement, and filtration with a long subterranean service life.
Composite and Cable Insulation: Acts as a reinforcement layer for Fiber Reinforced Plastics (FRP) and wrapping tape for high-voltage electrical cables. Ensures high dielectric strength and heat insulation.
Manufacturing and Quality Control
Reliability is our highest priority. We implement a multi-stage Quality Management System across our state-of-the-art production facility:
Raw Material Inspection: 100% virgin PET chips are thoroughly tested for moisture and viscosity before extrusion.
Online Defect Detection: Our spunbond lines are equipped with an advanced Online Infrared Inspection System to automatically detect and flag pinholes, thin spots, or contamination in real-time.
Laboratory Testing: Every production batch undergoes rigorous destructive testing in our in-house lab for GSM uniformity, tensile strength (MD/CD), elongation, and air permeability.
Traceability: Every roll is dispatched with a unique barcode and a Quality Certificate (COA), ensuring full lifecycle traceability from raw chip to finished product.

FAQ
Q: What are the main performance advantages of PET nonwoven fabric over PP nonwoven fabric?
A: PET nonwoven fabric provides much higher heat resistance (up to 150 Degrees Celsius compared to PP which degrades near 100 Degrees Celsius), significantly greater tensile strength, better UV stability for outdoor use, and a much longer lifespan under harsh chemical conditions.
Q: Can you provide customized technical parameters such as specific MD/CD tensile strength or air permeability?
A: Absolutely. We can adjust our polymer extrusion parameters, line speeds, and thermal calender settings to meet your exact Technical Datasheet (TDS) targets for tensile strength, thickness, and porosity.
Q: Does your polyester nonwoven fabric comply with strict environmental standards?
A: Yes, our materials are certified by SGS and fully comply with REACH and RoHS regulations. We can also provide Global Recycled Standard (GRS) certified materials upon request for sustainable projects.
Q: What is your standard lead time for an export order?
A: Generally, standard specifications take 12 to 15 days. Customized orders involving special surface treatments or custom color masterbatches are typically completed within 20 to 25 days after deposit and specification approval.
Q: How can I obtain technical samples for testing, and what is your sample policy?
A: We provide free sample swatches (A4 size or a small roll within 5 meters) for your lab testing and calibration. The buyer covers the initial express courier fee, which is fully refundable upon your first commercial container order.
