Hydrophilic Top sheet Nonwoven for Diaper
The hydrophilic top sheet nonwoven is the uppermost layer of a diaper that comes into direct contact with the baby's skin. It is designed to be soft, breathable, and skin-friendly, while also treated with hydrophilic agents to allow rapid fluid transfer to the absorbent core beneath. The hydrophilic property ensures that urine is quickly wicked away from the skin, keeping the surface dry and reducing the risk of diaper rash and irritation. Typically made from spunbond polypropylene or bicomponent fibers, the top sheet combines comfort with high-performance fluid management, making it a vital component in modern disposable baby and adult diapers.
