What is The Difference Between SMS And SMMS Nonwovens?

Nonwoven fabrics have become an essential part of our daily lives. From hygiene products to medical applications, nonwoven fabrics play a crucial role in providing us with comfort and safety. Among the various types of nonwoven fabrics, SMS and SMMS nonwoven fabrics are widely used. In this article, we will discuss what SMS and SMMS nonwoven fabrics are and the difference between them.

SMS Nonwoven Fabric:

SMS stands for "Spunbond Meltblown Spunbond." SMS nonwoven fabric is made by combining three layers of material: spunbond, meltblown, and spunbond. Spunbond and meltblown are two different processes of manufacturing fibers. Spunbond fibers are made by extruding melted polymer through a spinneret and then cooling and solidifying the fibers. Meltblown fibers, on the other hand, are made by blowing high-temperature air through molten polymer to create fine fibers. The combination of these two processes creates a nonwoven fabric that provides excellent barrier properties, absorbency, and strength. SMS nonwoven fabric is widely used in medical applications, protective clothing, and hygiene products.

SMMS Nonwoven Fabric:

SMMS stands for "Spunbond Meltblown Meltblown Spunbond." SMMS nonwoven fabric is made by adding an additional meltblown layer to SMS nonwoven fabric. This creates a four-layered fabric that provides even better barrier properties and absorbency. SMMS nonwoven fabric is also more durable and resistant to tearing. It is commonly used in surgical gowns, face masks, and other medical applications.

Difference between SMS and SMMS Nonwoven Fabric:

The main difference between SMS and SMMS nonwoven fabric is the number of meltblown layers used in their production. SMS nonwoven fabric has two meltblown layers, while SMMS nonwoven fabric has four meltblown layers. This extra layer creates a denser, more absorbent, and more durable material. SMMS nonwoven fabric can also provide better barrier protection than SMS nonwoven fabric.

In conclusion, SMS and SMMS nonwoven fabrics are essential materials used in many applications, from medical to hygiene products. They are both made from a combination of spunbond and meltblown processes, but the main difference lies in the number of meltblown layers used in their production. SMMS nonwoven fabric provides better barrier protection, absorbency, and strength than SMS nonwoven fabric. Nonwoven fabrics, including SMS and SMMS, have proven to be safe, reliable, and effective materials that enhance our daily lives.
