Custom Meltblown Non Woven Nonwoven Fabric

Product Specification

Meltblown nonwoven fabric is a type of synthetic nonwoven fabric produced using the meltblown process. The fabric is made by extruding molten polymer through fine nozzles and using high-pressure air to blow the fibers onto a conveyor belt, where they cool and bond to form a web. Meltblown nonwoven fabric is known for its fine fibers, high filtration efficiency, and absorbency, making it a versatile material used in a wide range of industries.

Material Composition and Manufacturing Process

1. Material Composition:
   • Meltblown nonwoven fabrics are primarily made from polypropylene (PP), a thermoplastic polymer known for its durability, moisture resistance, and lightweight properties. Other materials such as polyester (PET), polyamide (PA), and polylactic acid (PLA) can also be used, depending on the desired properties for the application.
2. Manufacturing Process:
   • The meltblown process begins with polymer pellets being melted in an extruder. The molten polymer is forced through small nozzles, where it is subjected to high-pressure air that blows the fibers into fine filaments.
   • These fibers are collected on a conveyor belt or drum, where they are laid randomly to form a web structure. The web is then bonded using heat or pressure to create a fabric with the desired properties.
   • The resulting fabric has extremely fine fibers, usually in the micron range, which gives it unique qualities like high filtration efficiency and high surface area.

Key Features of Meltblown Nonwoven Fabric

1. High Filtration Efficiency:

   • Meltblown fabric is primarily used for filtration applications because of its fine fiber structure, which allows it to trap small particles, bacteria, and viruses. It is widely used in face masks, respirators, and air filters due to its high filtration capacity.

2. High Surface Area:

   • The fine fibers in meltblown fabric create a large surface area relative to the fabric’s weight. This enhances its absorption and filtration capabilities, making it ideal for applications that require high-performance filtering or liquid retention.

3. Softness and Comfort:

   • Meltblown fabric is known for its softness and smooth texture, making it comfortable to wear in protective clothing and hygiene products that come in direct contact with the skin.

4. Liquid Barrier Properties:

   • Due to the dense network of fine fibers, meltblown nonwoven fabric offers excellent liquid barrier properties, making it ideal for applications such as diapers, sanitary napkins, and medical gowns.

5. Lightweight:

   • Despite its high density of fibers, meltblown nonwoven fabric is relatively lightweight, making it suitable for use in disposable products like face masks, wipes, and protective apparel.

6. Breathability:

   • Meltblown fabric retains a balance of breathability while offering filtering protection. This makes it a popular choice in products that require airflow but also need to prevent contaminants.

Applications of Meltblown Nonwoven Fabric

1. Medical and Healthcare:

   • Face Masks: Meltblown fabric is commonly used in the production of face masks, including surgical masks and N95 respirators, because of its superior filtration efficiency and bacteria-blocking properties.
   • Medical Gowns and Drapes: Meltblown fabric provides liquid barrier protection for medical gowns, surgical drapes, and other protective garments used in healthcare settings.
   • Wound Care: Due to its softness, absorbency, and fluid barrier properties, meltblown fabric is used in bandages and wound dressings.

2. Hygiene Products:

   • Diapers and Incontinence Products: Meltblown fabric is used in the absorbent core of diapers, baby wipes, sanitary napkins, and adult incontinence products due to its high absorption rate and moisture-locking properties.
   • Wet Wipes: Meltblown fabric is often used in the production of wet wipes for personal care and cleaning purposes.

3. Filtration Applications:

   • Air Filters: Due to its fine fibers, meltblown fabric is widely used in air filtration systems, including HVAC filters, air purifiers, and automotive cabin filters, to capture airborne particles.
   • Liquid Filters: Meltblown fabric is used in liquid filtration applications, including water filtration and oil filtration, to remove impurities and contaminants.

4. Protective Clothing:

   • Protective Apparel: Meltblown fabric is used in protective suits, coveralls, and gowns for industries where personal protection from chemicals, dust, or airborne particles is necessary, such as in cleanrooms or during hazardous material handling.

5. Environmental Protection:

   • Oil Spill Cleanup: Meltblown fabric is often used in booms and absorbent pads to clean up oil spills and chemical spills, thanks to its excellent absorbent properties.

6. Agriculture:

   • Meltblown fabric is used in agriculture to protect crops from pests and weather conditions. It is also used as a barrier for soil erosion control and in crop covers.

Advantages of Meltblown Nonwoven Fabric

1. High Performance:

   • Meltblown nonwoven fabric offers superior filtration, absorbency, and liquid resistance. It provides excellent performance in high-demand applications, especially in healthcare, hygiene, and industrial sectors.

2. Cost-Effective:

   • Meltblown fabric is produced using a relatively simple and efficient process, making it a cost-effective material, especially in disposable applications such as face masks and diapers.

3. Customization:

   • The properties of meltblown nonwoven fabric, including thickness, density, and fiber size, can be adjusted to meet the specific requirements of various industries, from high filtration efficiency in air filters to softness and absorbency in hygiene products.

4. Environmental Considerations:

   • Meltblown fabrics made from polypropylene are generally recyclable, and some manufacturers offer biodegradable options, helping reduce the environmental impact.

5. Comfortable to Wear:

   • Meltblown fabric is soft and breathable, making it suitable for use in protective clothing that requires both comfort and protection.
