Hydrophilic (Down) Nonwoven for Diaper
Hydrophilic (down) nonwoven for diapers is a specially engineered fabric designed to promote rapid fluid acquisition and transfer into the absorbent core, enhancing dryness and comfort for the user. Positioned just below the topsheet in the diaper structure, this layer plays a crucial role in wicking moisture away from the skin and distributing it evenly to the absorbent core (typically made of fluff pulp and superabsorbent polymer). The hydrophilic treatment applied to the nonwoven fibers ensures that urine is quickly absorbed, minimizing the risk of leakage and reducing rewet, which helps prevent diaper rash and skin irritation. Soft, breathable, and skin-friendly, this nonwoven is essential for the performance of modern baby and adult diapers.
