Application and Advantages of Meltblown Non-woven Fabric

Meltblown non-woven fabric has become an important part of the non-woven fabric industry with its superior performance and wide application prospects. Meltblown non-woven fabric is a material formed by melting polypropylene (PP) raw materials and spraying them out to form fine fibers, and then through electrostatic or hot pressing. It has excellent characteristics such as lightness, breathability, waterproofness and filtration, and is widely used in medical, health, environmental protection and industrial fields.

1. Structure and production process
The production process of meltblown non-woven fabric mainly includes melt extrusion, spinneret molding and hot pressing molding. First, the polypropylene particles are heated to a molten state, and then the molten polypropylene is sprayed out through the spinneret to form long and thin fibers. Then, these fibers are cooled in the air and intertwined together to form non-woven fabrics. Compared with traditional textile processes, the production process of meltblown non-woven fabrics is more efficient and can effectively reduce production costs.

2. Advantages and characteristics
Excellent filtering performance: The fiber fineness of meltblown nonwoven fabric is extremely small, which can effectively filter tiny particles in the air, such as dust, pollen and bacteria. This makes it an important material for making masks and air filters.

Lightweight and breathable: This nonwoven fabric is light in weight and has good breathability, making it suitable for use as a material for clothing linings, sanitary products and other products.

Waterproof performance: Meltblown nonwoven fabric can effectively prevent water and is suitable for protective clothing, surgical kits and other products in the medical and health fields.

Environmental protection and recyclable: Polypropylene materials are recyclable, and no harmful chemicals are used in the production process, which meets the requirements of modern environmental protection.

3. Application areas
The application areas of meltblown nonwoven fabrics are very wide, including but not limited to:

Medical and health: used to make masks, surgical gowns, medical sheets, etc.

Environmental protection: can be used to produce environmentally friendly products such as air filters and oil-water separators.

Consumer products: also widely used in household cleaning, personal care and sanitary products.

Construction and engineering: as an isolation layer or moisture barrier for building materials.
