Hot Air Nonwoven Fabric

Hot air non-woven fabric (also known as hot air-through nonwoven, through-air bonded nonwoven, or air-through thermal bonded nonwoven) is a type of nonwoven material produced by passing hot air through a web of loose fibers (often bicomponent fibers like PE/PP or ES fibers). The heat melts the low-melting-point components (e.g., the sheath of bicomponent fibers), bonding the fibers at crossover points upon cooling. This creates a fabric that is soft, fluffy, highly breathable, bulky/lofty, strong, and absorbent, without using chemical binders or excessive compression. It's environmentally friendlier than some other bonding methods and excels in applications requiring skin contact or air/liquid management.
