What is the difference between meltblown fabric and non-woven fabric?

Meltblown fabric mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. With many voids, fluffy structure and good wrinkle resistance, these ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown fabric has good filterability, shielding, heat insulation and oil absorption. . It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths and other fields.

What is Meltblown Fabric?

Polypropylene or PP Meltblown Nonwoven Fabric is made up of Polypropylene and its fiber diameter can be 1 to 5 microns with excellent oil absorption, heat insulation, filtration, and shielding capacity and properties. You get various anti-wrinkle fluffy structures and voids for PP Meltblown nonwoven fabric. Owing to its filtration properties and distinct capillary structures of the ultra-fine fibers it has applications in various filtration industries such as – air filters, face masks, N95 Face masks, water, and other industries. Owing to its complex fiber-structure that increases its surface area and the number of fibers per unit area, it imparts exquisite qualitie


 

Typical Production Procedure of PP Meltblown Nonwoven fabrics

To produce these technical fabrics, it must undergo several processes:

Step 1: Polymer Feeding

Step 2: Meltblown Extrusion

Step 3: Fiber Formation

Step 4: Fiber Cooling

Step 5: Forming Net

Step 6: Strengthening to form Cloth

The melt-blown cloth filter material is randomly distributed and bonded together by polypropylene microfibers, which are white, smooth and soft in appearance. The fiber fineness of the material is 0.5-1.0μm, and the random distribution of fibers provides more thermal bonding between fibers. Therefore, the meltblown gas filter material has a larger specific surface area and a higher porosity (≥75%). After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency, and high dust holding capacity.
