SMS Nonwoven Fabric
SMS nonwoven fabric has revolutionized industries with its exceptional versatility, durability, and affordability. From medical applications to hygiene products and industrial uses, SMS nonwoven fabric is at the heart of numerous essential products we use every day.
SMS nonwoven fabric technology is spun-melt, there are SMS, SMMS, SSMMS nonwoven fabric, it’s used for medical surgical gown, medical sheets, it’s also used for hygiene products, such as SPA bed sheets, leg cuff for baby diaper and cleaning wipes, industry wipes, etc.
What Is SMS Nonwoven Fabric?
SMS nonwoven fabric stands for Spunbond-Meltblown-Spunbond. It’s a tri-layer composite material composed of polypropylene that combines strength, softness, and excellent filtration properties.
Why SMS?
- Spunbond Layers: Offer durability and tensile strength.
- Meltblown Layer: Provides exceptional filtration efficiency.
- Cost Efficiency: Lightweight yet robust, making it cost-effective for mass production.
This unique structure allows SMS nonwoven fabric to be used in applications requiring breathability, water resistance, and filtration.
How Is SMS Nonwoven Fabric Made?
The production of SMS fabric involves combining spunbond and meltblown processes in a seamless operation.
Step-by-Step Process
- Spunbond Layers: Polypropylene is melted and extruded through spinnerets to form continuous filaments, which are then bonded.
- Meltblown Layer: A fine mesh of fibers is created using high-speed air streams, providing filtration.
- Lamination: The layers are thermally or chemically bonded together.
| Layer | Function |
|---|---|
| Spunbond | Strength and structure |
| Meltblown | Filtration and barrier |
| Spunbond | Comfort and durability |
This process ensures the material’s lightweight and multifunctional properties.
What Are the Characteristics of SMS Nonwoven Fabric?
SMS nonwoven fabric boasts a range of desirable properties that make it indispensable.
Key Characteristics
- Breathable and Lightweight: Ensures comfort in wearable applications.
