Absorption Speed vs. Rewet: Two Key Metrics That Define a Premium Baby Diaper

1. Absorption Speed: The Race Against Time for Skin Protection

Absorption speed measures the time required for liquid to penetrate from the diaper surface into the absorbent core. Industry standards typically require multiple absorption times to stay within 30 seconds. The faster the speed, the shorter the duration that liquid remains on the top sheet in contact with the skin, effectively reducing urine-related irritation. The key to achieving rapid absorption lies in the top sheet's fluid acquisition design, aperture technology, and the highly permeable structure between core layers. If absorption is too slow, liquid spreads laterally across the surface, increasing the risk of side leakage and prolonging skin exposure to a moist environment.
