Liquid Strikethrough and Rewet in Hygiene Products
topic
Strikethrough time measures the speed at which a standardised liquid volume passes through a nonwoven topsheet into an absorbent core, while rewet testing measures liquid returned to the surface from a saturated core under a standardised pressure load; both metrics directly predict the dry-feel performance of nappies and feminine hygiene products.
Role
Core performance parameters for hygiene nonwoven product development and quality control, determining the balance between rapid liquid acquisition and surface dryness that governs infant skin health and consumer satisfaction with absorbent hygiene products.
