Spunbond and meltblown are two different processes used to manufacture nonwoven fabrics. Here's a breakdown of the differences between spunbond and meltblown nonwoven fabrics:

Spunbond Nonwoven:

    Spunbond nonwoven fabric is produced by extruding continuous filaments of thermoplastic polymers, such as polypropylene or polyester, and then bonding them together.
    The extruded filaments are laid down in a random manner to form a web-like structure.
    The filaments are then bonded together using heat, pressure, or adhesives to create a cohesive fabric.
    Spunbond nonwoven fabrics have a relatively uniform structure and offer good strength and stability.
    They have excellent breathability and are often used in applications such as hygiene products (diapers, wipes), medical products, agricultural covers, geotextiles, and packaging.

Meltblown Nonwoven:

    Meltblown nonwoven fabric is manufactured using a meltblown process where thermoplastic polymers are melted and extruded through small nozzles called spinnerets.
    The extruded molten polymer is blown by high-speed hot air or gas, which stretches and attenuates the polymer into very fine fibers.
    These fine fibers are randomly dispersed and collected on a moving conveyor or drum to form a nonwoven web.
    Meltblown nonwoven fabrics have extremely fine fibers, typically in the microfiber range, which gives them unique properties such as high filtration efficiency and excellent barrier properties.
    They are commonly used in applications such as filtration media (face masks, air filters), medical protective apparel, absorbent products, insulation materials, and oil sorbents.

Key Differences:

    Fiber Size: Spunbond fabrics have relatively thicker and larger-diameter fibers compared to the ultra-fine fibers of meltblown fabrics.
    Fabric Structure: Spunbond fabrics have a more uniform and stable web structure, while meltblown fabrics have a more random and fibrous structure.
    Strength: Spunbond fabrics generally have higher strength compared to meltblown fabrics.
    Filtration Efficiency: Meltblown fabrics have higher filtration efficiency due to their finer fibers, making them more suitable for filtration applications.
    Barrier Properties: Meltblown fabrics provide better barrier properties against small particles, liquids, and aerosols compared to spunbond fabrics.
    Cost: Meltblown fabrics are generally more expensive to produce compared to spunbond fabrics due to the complexity of the process and the use of specialized equipment.

Both spunbond and meltblown nonwoven fabrics have their own unique characteristics and are used in a wide range of applications based on their specific properties.JIASHAN HH Nonwovens Machinery CO., Ltd is China nonwoven fabric manufacturers and OEM medical nonwoven fabric factory.
