How can you tell if a fabric is meltblown? Meltblown nonwoven fabric is to use high - speed hot air flow to draw the thin stream of polymer melt extruded from the spinneret hole of the die, thereby forming ultra - fine fibers and collecting them on the condensing screen curtain or drum. At the same time, it is self - bonded to become a melt blown nonwoven fabric. Meltblown nonwoven mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 - 5 microns. Melt blown nonwoven has many voids, fluffy structure and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, thermal insulation and Oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorb…
