At Guanlong Waterproof Materials Co., Ltd., we specialize in advanced waterproofing materials, and one of our core products is the nonwoven polyester mats — a durable and versatile material that plays a crucial role in waterproofing systems and beyond.
This blog post takes you through the production process and key advantages of nonwoven polyester mats, widely used in construction, roofing, and filtration.
What is Nonwoven Polyester Mats?
Manufacturers produce nonwoven polyester mats by bonding continuous polyester fibers through thermal or mechanical processes — without weaving or knitting. This technical fabric offers strength, flexibility, and excellent compatibility with bituminous materials, making it a preferred base layer in various industrial and construction applications.
Production Process of Nonwoven Polyester Mat
The manufacturing of nonwoven polyester mat involves a series of highly controlled steps to ensure performance consistency:
1. PET Chip Drying
The process begins with drying polyester (PET) chips to eliminate moisture, preventing defects during melting.
2. Melting and Extrusion
Dried chips are melted and extruded through spinnerets, forming long polyester filaments.
3. Fiber Drawing and Cooling
The hot filaments are rapidly stretched and cooled with air. This step increases the fiber strength and alignment.
4. Web Forming
These filaments are laid randomly on a conveyor belt to form a fiber web, creating the base structure of the mat.
5. Thermal Bonding
The web passes through heated rollers, bonding the filaments together and forming a strong, cohesive nonwoven mat.
6. Rewinding
The finished mat is rolled up and prepared for delivery, ready to be used in various applications including bitumen waterproof membranes.
Key Advantages of Nonwoven Polyester Mat
Our nonwoven polyester mat offers multiple performance benefits across industrial uses:
🔹 High Strength and Stability
Its continuous filament structure ensures excellent mechanical strength and dimensional stability.
🔹 Thermal Resistance
It maintains structural integrity under high temperatures, making it ideal for use in bituminous processing.
🔹 Bitumen Compatibility
The mat’s surface and structure bond seamlessly with bitumen, ensuring waterproof layer integrity.
🔹 Smooth Surface Texture
Uniform thickness and smoothness improve adhesion and minimize irregularities in application.
🔹 Cost-Effective Solution
With efficient production and long-term durability, it offers great value for roofing and construction projects.
Applications of Nonwoven Polyester Mat
-
Bitumen Waterproof Membranes: As a reinforcement layer in SBS or APP modified bitumen systems.
