SMS nonwoven fabric is a versatile material used in various industries due to its strength, durabilidade, e excelentes propriedades de barreira. Este tecido combina dois tipos diferentes de tecnologia de polipropileno: fiado and derretido. The result is a three-layer fabric structure known as SMS (Spunbond-Meltblown-Spunbond). This unique composition offers a variety of benefits, including enhanced filtration and fluid resistance.
How is SMS Nonwoven Fabric Made?
Process | Function |
---|---|
Spunbond Layer | Provides strength and durability |
Meltblown Layer | Offers filtration, barrier, and absorbent properties |
Colagem Térmica | Combines layers to create a cohesive fabric |
What Are the Advantages of SMS Nonwoven Fabric?
- Strength and Durability: The spunbond layers provide excellent tensile strength, while the meltblown layer adds to the fabric’s ability to resist punctures and wear.
- Filtração: The meltblown layer provides fine fiber structure, making SMS nonwoven fabric ideal for filtration applications, such as surgical masks, gas filters, and liquid filtration.
- Barrier Properties: SMS fabric is commonly treated to enhance its resistance to fluids, particles, and contaminants, making it ideal for medical and hygiene products.
- Breathability: Despite its excellent barrier properties, SMS fabric remains breathable, which is essential for products like surgical gowns and face masks.
Applications of SMS Nonwoven Fabric
- Medical and Healthcare: SMS fabric is widely used in surgical drapes, surgical gowns, face masks, and other hygiene products. Its ability to resist fluids and provide a sterile environment makes it ideal for medical use.
- Filtração: Due to its fine structure, SMS fabric is used in air, gas, and liquid filtration, including high-efficiency filters for industrial applications.
- Sanitary Products: Disposable items such as diapers, feminine care products, and incontinence pads often use SMS fabric due to its absorbency and comfort.
- Industrial Applications: SMS fabric is also used in various industrial applications, including geotextiles, insulation materials, and cleaning wipes.

How Does the SMS Spunmelt Machine Work?
The production of SMS nonwoven fabric relies on the SMS Spunmelt Machine, a highly efficient piece of equipment. This machine integrates the spunbond and meltblown processes into a single production line.
- Extruder: Melts the polypropylene granules to form fibers.
- Spinneret: Extrudes the fibers into continuous filaments.
- Quenching System: Cools the fibers to solidify them.
- Meltblown Unit: Uses high-velocity air to form fine fibers and create the middle layer.
- Calendaring Unit: Compresses and bonds the layers together to create the final fabric.
