PET Spunbond Nonwoven Fabric

PET Spunbond Nonwoven Fabric Product Highlights

Mechanical Properties: Tensile strength 55–75 MPa, flexural strength 90–120 MPa (high strength).
Thermal Properties: Excellent heat resistance, with long-term operating temperature from -40°C to 150°C.
Chemical Resistance: Resistant to weak acids, weak alkalis, and organic solvents, but not resistant to strong alkalis or prolonged hot water immersion.
Moisture Absorption: Low moisture absorption (0.4%–0.8%), but prone to static electricity.

Key Advantages of PET Nonwoven Fabric

PET nonwoven fabric is widely recognized for its excellent dimensional stability, high tensile strength, and thermal resistance, making it a preferred material for industrial and long-life applications.

Compared with many general-purpose nonwoven materials, PET nonwoven fabric maintains its shape and structure even under high temperature, continuous tension, or long-term use. This characteristic is especially important in filtration, automotive interiors, insulation layers, and technical textiles.

Another major advantage is its uniform fiber structure and consistent quality. PET fibers allow better control over thickness, strength, and surface performance, which helps manufacturers achieve stable results during downstream processing such as lamination, coating, or composite bonding.

PET nonwoven fabric also offers good chemical resistance and low moisture absorption, allowing it to perform reliably in humid or chemically demanding environments. For buyers who prioritize durability, performance consistency, and product lifespan, PET nonwoven fabric is often the most practical solution.

PET Nonwoven Fabric vs PP Nonwoven Fabric – When Does PET Make More Sense?

Both PET and PP nonwoven fabrics are widely used, but they are designed for different performance priorities and application scenarios.

PP nonwoven fabric is typically chosen for lightweight, disposable, and cost-sensitive applications, such as hygiene products and short-term protective uses. It offers excellent softness and flexibility at a competitive price.

PET nonwoven fabric, however, is better suited for applications that require higher temperature resistance, stronger mechanical performance, and long-term dimensional stability. It performs well in environments where materials are exposed to heat, tension, or repeated use.

If your application involves industrial filtration, automotive components, insulation materials, or technical composites, PET nonwoven fabric is often the more reliable option. Choosing PET is not about replacing PP but about selecting the right material for performance-critical and long-life applications.

Functional Treatments & Surface Finishing Options

To meet different technical and market requirements, PET nonwoven fabric can be customized with various functional treatments and surface finishes:

Hydrophilic Treatment
Improves liquid absorption and fluid distribution; commonly used in filtration and industrial processing layers.

Hydrophobic Treatment
