What Is Spunbond Nonwoven Fabric?
Spunbond nonwoven fabric is a type of material made by directly bonding continuous filaments of polymer, like polypropylene, into a web without weaving or knitting.
When you use this fabric, you’ll notice it’s lightweight yet strong, offering excellent durability and breathability. It’s resistant to tearing and doesn’t easily absorb moisture, making it ideal for various applications.
You’ll find spunbond fabric in products like medical masks, hygiene items, and agricultural covers because it provides reliable protection while allowing air to pass through.
Its smooth surface and uniform texture make it comfortable for skin contact.
Unlike traditional textiles, spunbond nonwoven fabric combines strength and flexibility without the complex interlacing of threads, giving you both performance and cost efficiency in one versatile material.
The Manufacturing Process of Spunbond Fabrics
Now that you understand what spunbond fabric is, let’s explore how it’s made.
You’ll see how polymer melting and extrusion create fibers, which are then drawn and formed into webs.
Finally, various bonding techniques hold the fabric together.
Polymer Melting and Extrusion
Although it may seem complex, the process of polymer melting and extrusion forms the essential first step in creating spunbond nonwoven fabrics.
You start by feeding polymer pellets—usually polypropylene—into a heated extruder. The extruder melts the pellets into a uniform, viscous liquid by applying precise heat and pressure.
Once melted, you push this polymer melt through a spinneret, a metal plate with tiny holes, to shape the molten polymer into continuous filaments. Controlling temperature and pressure here is imperative because it affects the quality and consistency of the fibers.
This extrusion step prepares the polymer for the next stages in spunbond fabric production, ensuring the material flows smoothly and evenly before it transforms into fibers.
Fiber Formation and Drawing
Once the polymer melt passes through the spinneret, you guide the continuous filaments through a drawing process that stretches and thins them to the desired diameter.
This step is essential for defining fiber strength, uniformity, and overall fabric quality.
You control the fiber formation and drawing by carefully adjusting:
- Drawing speed – Faster speeds thin the fibers more, affecting tensile strength.
- Temperature – Maintaining ideal heat guarantees fibers remain pliable during stretching.
- Spinneret design – Hole size and shape influence initial filament thickness.
- Cooling rate – Proper cooling solidifies fibers uniformly, preventing defects.
Web Bonding Techniques
After forming and drawing the fibers to the right specifications, the next step is bonding them into a cohesive web. You’ll use web bonding techniques to stabilize the fiber network, guaranteeing strength and durability.
Thermal bonding is the most common method, where you apply heat and pressure through heated rollers or ultrasonic waves to fuse fibers at contact points. You can also use chemical bonding, applying adhesives to hold fibers together, though it’s less typical for spunbond fabrics.
Mechanical bonding methods like needle punching are rare here but can add texture. Choosing the right bonding technique depends on your fabric’s intended use, balancing strength, flexibility, and breathability.
Key Properties and Benefits of Spunbond Materials
You’ll find spunbond materials are lightweight yet durable, making them easy to handle without sacrificing strength.

Comparing Spunbond to Other Nonwoven Technologies
Spunbond fabrics have proven their worth across many industries, but understanding how they stack up against other nonwoven technologies can help you choose the best material for your needs.
Spunbond fabrics excel across industries, and comparing them to other nonwovens ensures the right material choice.
Compared to meltblown, spunbond offers greater strength and durability, making it ideal for reusable applications. Unlike spunlace, spunbond has higher tensile strength but less softness, so consider comfort versus toughness.
When matched with carded nonwovens, spunbond generally provides better uniformity and filtration properties.
Here’s a quick comparison:
- Strength: Spunbond > Meltblown and Spunlace
- Softness: Spunlace > Spunbond
- Filtration: Meltblown > Spunbond
