Melt-blown method is one of the polymer directly into the net method, it is the screw extruder extrusion of polymer melt through the high temperature air blowing or other means to melt trickle extreme tension and the formation of a very fine fiber, then gathered into a net roller or a net curtain formed on the fiber network, finally the adhesion effect since the made method of melt-blown fiber is strengthened and the weaving.

Polypropylene is the main raw material of melt blown cloth, and the diameter of fiber can reach 1-5 microns. These microfibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filtration, shielding, thermal insulation and oil absorption. It can be used in air, liquid filter material, isolation material, absorbing material, mask material, heat preservation material, oil absorbing material and wiping cloth.
