Here’s how SMS Composite Nonwoven Fabric is typically produced:

  1. Spunbond Layer: Thermoplastic polymer (usually polypropylene) is melted and extruded through spinnerets to form continuous filaments, which are laid down to form a nonwoven web.

  2. Meltblown Layer: Another layer of thermoplastic polymer is melted and extruded through fine nozzles with high-velocity air to create fine fibers, forming a dense, porous web.

  3. Second Spunbond Layer: A final layer of spunbond material is added on top, creating a sandwich structure.

  4. Bonding: The three layers are bonded together using heat, pressure, or adhesives to form the final SMS fabric.

key Characteristics

  1. Strength: The spunbond layers provide excellent tensile strength and durability, making the fabric resistant to tearing and stretching.

  2. Barrier Protection: The meltblown layer in the middle acts as a barrier to fluids, particulates, and microbes, providing high filtration efficiency and protection.

  3. Breathability: Despite its barrier properties, SMS fabric is breathable, allowing air and moisture vapor to pass through, which enhances comfort in various applications.

  4. Softness: SMS fabric can be engineered to be soft to the touch, making it comfortable for applications involving direct contact with the skin.

  5. Chemical Resistance: Depending on the type of polymer used, SMS fabric can exhibit resistance to various chemicals, making it suitable for industrial and medical uses.

  6. Versatility: The combination of spunbond and meltblown layers allows for a versatile range of properties, making SMS fabric suitable for diverse applications.
