SMS Non-Woven Fabric: Characteristics, Applications, and Advantages Explained in 2023

SMS non-woven fabric, also known as Spunbond Meltblown Spunbond, is a versatile material that finds its application in various industries. This fabric is made up of layers of spun-bond polypropylene, melt-blown polypropylene, and spun-bond polypropylene again, hence the name SMS. Its unique combination of properties makes it suitable for a wide range of applications. This article will explore the characteristics, uses, and advantages of SMS non-woven fabric.


SMS non-woven fabric is a type of engineered fabric that is manufactured using a specialized process. It offers a unique combination of strength, durability, and breathability, making it suitable for a wide range of applications. Whether you’re in the medical, automotive, or hygiene industry, SMS non-woven fabric has several advantages that set it apart from other materials.

What is SMS non-woven fabric?

SMS non-woven fabric is composed of three layers of polypropylene. The first and third layers are made through spun bonding, where the polypropylene fibers are spun and bonded together. The middle layer is created using melt-blown technology, where the fibers are melted and blown to form a fine web. Combining these layers provides unique properties to the fabric, including high strength, barrier protection, and breathability.

Manufacturing process

The manufacturing process of SMS non-woven fabric involves several steps:

  1. Spunbonding: In this step, the polypropylene fibers are extruded, cooled, and stretched to form a continuous web. The fibers are then bonded together using heat and pressure.
  2. Melt Blowing: In the next step, the melt-blown technology is used to create the middle layer. The polypropylene resin is melted and extruded through small nozzles, forming microfibers. These microfibers are then blown by hot air onto a conveyor belt, creating a fine web.
  3. Spunbonding (again): The final step involves another round of spun bonding to add the third layer. The process is similar to the initial spun bonding step, where the fibers are bonded together to form a stable fabric.
