Meltblown Non-Woven Fabric is a specialized type of non-woven fabric that is manufactured using the meltblown process, which involves the extrusion of molten polymer to create fine, randomly oriented fibers. This process is known for producing fabrics with high filtration efficiency and unique performance characteristics.

Production Process:

1. Melt Spinning: Polymer resin (typically polypropylene) is melted and forced through a die with tiny nozzles to form very fine fibers.
2. Fiber Formation: The molten polymer is blown by high-velocity hot air to stretch and cool the fibers, which are then collected on a conveyor belt or collection device.
3. Web Formation: The fine fibers are laid down in a random pattern, forming a web. This web is then bonded together using heat, pressure, or adhesive to create the final fabric.

Material:

• Polypropylene (PP): The most commonly used polymer in meltblown fabrics due to its cost-effectiveness, lightweight properties, and good chemical resistance.
• Other Polymers: In some cases, other polymers or blends may be used to enhance specific properties of the fabric.

Characteristics:

• High Filtration Efficiency: The fine fiber diameter and random web structure make meltblown fabric highly effective at filtering particles, including bacteria and viruses.
• Softness: Despite its high filtration capability, meltblown fabric can be very soft, making it comfortable for use in direct contact with skin.
• Low Density: The fabric has a low density due to the fine fibers, which contributes to its lightweight nature.
• Liquid Barrier: Meltblown fabric provides a good barrier against liquids, making it suitable for applications that require protection from spills or moisture.
• Breathability: It is breathable, allowing for airflow while maintaining its filtration and barrier properties.

Applications:

• Medical and Healthcare: Commonly used in surgical masks, N95 respirators, and other protective garments where high filtration efficiency is required.
• Hygiene Products: Utilized in disposable diapers, feminine hygiene products, and adult incontinence products for its absorbency and skin comfort.
• Industrial Filters: Employed in air and liquid filters due to its ability to capture fine particles.
• Protective Clothing: Used in various types of protective clothing, including disposable gowns and coveralls, to provide a barrier against contaminants.

In summary, meltblown non-woven fabric is highly valued for its superior filtration, barrier properties, and comfort, making it an essential material in healthcare, hygiene, and industrial applications.
