Absorbency Testing and Performance Characterisation
topic
Airlaid nonwoven absorbency characterisation uses total absorbent capacity by gravimetric immersion measurement, acquisition rate by timed liquid absorption on defined area, rewet by pressure extraction after defined liquid loading, and capillary suction measurement of wicking rate, with standardised methods from EDANA, INDA, and ISO enabling comparison of airlaid absorbency performance against specification requirements for hygiene product applications.
Role
Provides the performance characterisation data for airlaid absorbent products that enables specification setting, product development, and quality control of the absorbency properties that are the primary functional requirements of airlaid nonwovens in hygiene product applications, with comprehensive absorbency testing covering multiple dimensions of fluid handling behaviour that together determine the clinical effectiveness and consumer experience of the hygiene product.
