AZX Nonwoven Machinery, a globally renowned and reliable nonwoven machine supplier from China, provides a variety of production solutions for nonwoven waterproof materials based on extensive customer service experience. For nonwoven manufacturers, we analyze these solutions through two major systems based on raw material form (Chips vs. Staple Fiber) and processing depth (Base Fabric vs. Finished Membrane).
1、Polyester Spunbond (Continuous Filament) System
This production route uses polyester chips as the raw material and is characterized by high-strength output and continuous manufacturing.
A. Spunbond Geotextile
Process: Polyester chips are extruded and spun into filaments, which are then formed into a web and reinforced via needle-punching.
Performance: High tensile strength and excellent permeability for filtration and drainage.
Applications: Civil engineering projects requiring soil stabilization and reinforcement.
B. Spunbond Mat for Bitumen Membranes
Process: This follows the spunbond needle-punched line but adds an Impregnation Treatment.
Performance: Enhanced dimensional stability and superior bonding with bitumen.
Applications: High-end base fabric (carrier) for premium bitumen waterproofing membranes.
C. Fiberglass Reinforced Spunbond Mat
Process: Incorporates glass fiber reinforcement during the spunbond and needle-punching phase, followed by impregnation.
Performance: Maximum resistance to thermal expansion and contraction.
Applications: Heavy-duty waterproofing membranes for demanding structural environments.
2、Polyester Staple Fiber (Short Fiber) System
This system utilizes pre-cut polyester staple fibers and relies on mechanical carding to form the web.
A. Staple Fiber Geotextile
Process: Polyester staple fibers undergo Carding followed by Needle-punching.
Performance: Excellent flexibility and high loft, ideal for protective cushioning.
Applications: Filtration, separation, and protection in road and railway construction.
B. Staple Fiber Mat for Bitumen Membranes
Process: The staple fiber web is subjected to impregnation treatment to create a “Polyester Mat”.
Performance: Cost-effective carrier with good bitumen absorption.
Applications: Standard-grade bitumen waterproofing membranes.
C. Fiberglass Reinforced Staple Mat
Process: Adds a fiberglass reinforcement layer to the staple fiber carding and needle-punching line.
Performance: Improves the tensile strength of the staple fiber base to meet higher engineering standards.
Applications: Reinforced carriers for specialized waterproofing tasks.
3、Final Product: Bitumen Waterproofing Membrane
Regardless of whether a Spunbond or Staple Fiber base is used, the final conversion into a finished membrane follows these steps:
Reinforcement Base: Selection of the polyester mat (Spunbond or Staple, with or without Fiberglass).
Bitumen Coating: The mat is passed through a bitumen coating process.
Finished Product: The result is a Finished Waterproofing Membrane ready for site application (e.g., torch-on roofing).

4、Technical FAQ for Nonwoven Manufacturers
The distinction lies primarily in the processing depth and the intended application:
Geotextile: This is the “raw” fabric produced directly from the needle-punching line. It is used for filtration, drainage, and soil separation in civil engineering.
Polyester Mat (Base Fabric): This is a geotextile that has undergone Impregnation Treatment. This chemical treatment stiffens the fabric and prepares it to be coated with bitumen.
Reinforced Mat: This material includes an extra layer of Glass Fiber (Fiberglass) during the production process. This reinforcement significantly limits thermal shrinkage and increases the tensile strength of the final waterproofing membrane.
The choice depends on your target market’s quality requirements and your budget:
Material Input: Spunbond lines use Polyester Chips , while Staple lines use Polyester Staple Fibers.
Performance: Spunbond (Long Filament) provides superior mechanical strength and puncture resistance because the fibers are continuous. Staple Fiber (Short Fiber) is more flexible and offers better “bulk” or loft.
Selection Logic:
Choose Spunbond for high-end, high-specification infrastructure projects and premium waterproofing brands.
Choose Staple Fiber for general construction, standard-grade waterproofing, or projects where cost-efficiency is the priority.
Your choice should be guided by your position in the supply chain:
To sell to construction contractors: Invest in a PET Spunbond or Staple Needle-punched Geotextile line to produce finished rolls for soil work.
To sell to waterproofing factories: You need the Impregnation Treatment modules to produce the “Mat” (Base fabric) used as a carrier.
To produce the final retail product: You must add a Bitumen Coating line to turn the polyester mat into a Finished Waterproofing Membrane.
Although this article outlines the standard processes for various technologies, AZX Machinery offers customized production line services.
Geotextile Lines: Typically range from 3.2 meters to 6 meters to cover large areas in civil engineering.
Waterproofing Mat Lines: Usually standardized between 1 meter and 2 meters to match the common width of commercial bitumen rolls.
Yes. The production flow shows that Fiberglass Reinforcement and Impregnation Treatment are modular steps. AZX Machinery designs these lines so that a basic needle-punching unit can be integrated with reinforcement modules to produce higher-value materials as your business grows.
