Runoff

Hygienic disposable products such as baby diapers are expected to possess optimum fluid handling characteristics for maximum leakage protection, skin protection, functionality and comfort. As one of the vital parts of the diaper, the topsheet or coverstock is designed to quickly transfer fluids to the core while remaining soft and dry. Its function is characterized by key performance indicators such as rewet, strike-through time and run-off.

Together with the internationally renowned testing instruments LISTER AC and WETBACK for analysis of the liquid strike-through time and the rewet properties, Lenzing Instruments also offers an automated solution for the run-off test. RUNOFF offers controlled and standardized measurement of the run-off liquid collected from a coverstock specimen being exposed to a certain amount of liquid on an inclined table according to INDA/EDANA
WSP 80.9.

Lenzing Instruments RUNOFF features adjustable dosing volume as well as variable inclination of the run-off table for flexible and
individual testing procedures, including the basic, repeated and modified testing procedure as specified by INDA/EDANA. A container replaces the receiver pad for collection of the run-off liquid, meaning easier weighing and lower costs for consumables. The standardized and automated operation means highest reproducibility and accuracy, and together with LISTER AC and WETBACK, RUNOFF gives valuable feedback on the fluid management of the nonwoven material.

Automated instrument for quantification of the run-off properties of nonwoven coverstock/topsheet according to INDA/EDANA-standards WSP 80.9,equivalent to ERT 152.2.
