What is SMS fabric and how is it different to spunbond fabric?

SMS and Spunbond fabrics are two completely different materials that have different applications. While SMS is a modern technology that has many uses, Spunbond fabric is an older material that is more commonly used for clothing purposes.

What is SMS?

SMS stands for "Spunbond Meltblown Spunbond." It is a nonwoven fabric that is made using a combination of spunbond and meltblown technologies. This fabric is mainly composed of polypropylene and is widely used for various purposes.

There are three layers in an SMS fabric- the outer layer, the meltblown layer, and the inner layer. The outer layer has high strength and is responsible for providing the fabric with structure. The meltblown layer is responsible for providing the fabric with filtering properties, while the inner layer is soft and comfortable to wear.

The SMS fabric is known for its porous structure, making it an excellent choice for use as a hyperfiltration membrane. It can also be used in the manufacture of surgical gowns, face masks, and other medical-grade items. SMS fabrics are popular because of their ability to block out liquids and bacteria, which helps to keep patients and medical personnel safe.

What is Spunbond Fabric?

Spunbond fabric, also known as spun bonded nonwoven fabric, is a type of fabric that is made using a spunbond technology. It is mainly composed of polypropylene and is commonly used in making clothing, tablecloths, bags, and industrial materials.

Spunbond technology involves melting the polypropylene and extruding it through tiny holes in a spinneret. The fibers then cool and bond together to form a sheet of material.

Spunbond fabrics are known for their strength, durability, and low cost. They are commonly used in industrial applications because of their ability to provide excellent protection against dust, dirt, and other particles.

Key differences between SMS and Spunbond fabrics

1. Composition

SMS fabrics are made using a combination of spunbond and meltblown technologies, while Spunbond fabrics are made using only spunbond technology. The presence of a meltblown layer in SMS fabrics gives it different properties, such as the ability to filter out bacteria and liquids.

2. Purpose

SMS fabrics are used in various applications, such as medical-grade items, hyperfiltration membranes, and other industrial uses. Spunbond fabrics, on the other hand, are commonly used for clothing, bags, and as industrial materials.

3. Physical structure

SMS fabrics have a three-layer structure that provides them with different properties. Spunbond fabrics, on the other hand, have a uniform structure that provides them with strength, durability, and resistance to water and other particles.

In conclusion, SMS and Spunbond fabrics are two completely different materials that have different applications. While SMS is a modern technology that has many uses, Spunbond fabric is an older material that is more commonly used for clothing purposes. Although they are both composed of polypropylene, their composition, purpose and physical structure are different.
