Spunbond nonwoven is primarily made from polypropylene, with fiber diameters ranging from 1 to 5 micrometers. Its high porosity, fluffy structure, and excellent wrinkle resistance are due to the unique capillary structure of the ultra-fine fibers, which increase the number and surface area of fibers per unit area. This makes spunbond nonwoven excellent for filtration, shielding, insulation, and oil absorption. It is used in various fields such as air and liquid filtration materials, isolation materials, absorbent materials, mask materials, thermal insulation materials, oil absorbent materials, and wiping cloths.
