Hot air nonwoven fabric (also known as through-air bonded nonwoven, hot air through nonwoven, or air-through thermal bonded nonwoven) is a type of nonwoven material produced using a thermal bonding process where heated air penetrates a loose fiber web to melt and fuse thermoplastic fibers (typically bicomponent fibers like PE/PET or ES fibers). This creates a soft, bulky, and porous fabric without the need for chemical binders or water, making it environmentally friendly and ideal for skin-contact applications.
