Hygiene nonwoven hydrophilicity cannot be judged by a drop test alone. Different indicators reflect liquid intake, repeated-use scenarios and surface dryness.
Strike-through time
Indicates how quickly liquid passes through the topsheet — a good baseline for initial screening.
Multi-strike time
Repeated testing shows performance under multiple liquid insults — essential for comparing multi-use hydrophilic options.
Rewet
Rewet correlates with surface dryness in use and should be assessed together with the full product structure.
When comparing additives, request samples and state your target values.
