Medical Wicking Laboratory Testing: Immersion
Wicking testing measures how quickly and how far liquids travel through fabrics via capillary action. The test suspends a fabric strip vertically with its lower edge in a liquid reservoir and tracks the rise height over time. For medical manufacturers, controlled wicking is critical in surgical gowns, drapes, masks, and absorbent layers to manage fluid without allowing strike-through while preserving comfort and breathability.
In clinical settings, the ability of textiles to handle liquids intelligently can mean the difference between effective barrier protection and fluid penetration. Too much wicking in the wrong areas can compromise sterility, while insufficient wicking in absorbent zones can leave fluids pooling on the surface. Applus+ Reliable Analysis already maintains accredited capabilities for wicking, absorption, water repellency, and full barrier performance testing, creating a comprehensive toolkit for liquid management in medical textiles.
These evaluations support major standards such as AAMI PB70 for surgical gowns and EN 13795 for European compliance. Manufacturers rely on wicking data to engineer materials that transport fluids away from critical zones, reduce infection risk, and improve wearer comfort. Applus+ Reliable Analysis delivers consistent, reproducible results using equipment already operating daily under our ISO/IEC 17025 accreditation.
Common Wicking Medical Testing Standards
AATCC 197 for Vertical Wicking of Textiles
AATCC 197 measures the vertical wicking ability of textiles by suspending a fabric strip vertically with its lower edge in contact with a reservoir of liquid (typically water or saline) and timing how far the liquid rises over a specified period. The test reports wicking height at defined intervals. It is widely used for surgical gowns, drapes, isolation apparel, and medical barrier fabrics to characterize liquid transport behavior, helping ensure materials manage fluid without excessive strike-through while maintaining comfort and barrier performance.
ISO 9073-6 Textiles Part 6 Absorption
ISO 9073-6 determines the absorption capacity and rate of nonwoven fabrics by measuring the amount of liquid absorbed under controlled conditions. The standard evaluates both the speed and total volume of liquid uptake. It is essential for medical nonwovens used in surgical masks, gowns, drapes, and absorbent layers, where controlled absorption and wicking properties directly influence fluid management and overall barrier effectiveness.
ISO 9073-12 Textiles Demand Absorbency with Wicking Correlation
ISO 9073-12 measures demand absorbency of nonwovens, which correlates closely with wicking behavior by determining the rate and capacity of liquid uptake under low hydrostatic pressure. The standard simulates conditions where the material draws liquid as needed. It is particularly valuable for medical absorbent layers, wound care products, and protective apparel where controlled wicking helps manage fluids without compromising barrier properties.
