Melt-blown cloth is mainly made of polypropylene as the main raw material, and the fiber diameter can reach 1 ~ 5 microns. With many voids, fluffy structure and good anti-folding ability, these microfibers with unique capillary structure increase the number and surface area of fibers per unit area, so that melt-blown cloth has good filter, shielding, insulation and oil absorption. It can be used for air and liquid filtration materials, isolation materials, absorbing materials, mask materials, warm materials, oil absorbing materials and wiping cloth and other fields.
