Diaper nonwoven refers to a type of nonwoven fabric used in the construction of disposable diapers. Nonwoven fabrics are made from synthetic fibers (like polypropylene, polyester, or a combination) that are bonded together without the need for weaving or knitting. In the context of diapers, nonwoven materials are used for several critical components, including the topsheet, backsheet, and leg cuffs. They play an important role in moisture management, comfort, breathability, and structural integrity.
