Single-use and multi-use hydrophilicity are not about better or worse performance — they serve different applications. Start by clarifying your substrate, end use and test requirements.
When single-use hydrophilicity matters
For basic liquid strike-through needs, start with single-use hydrophilic performance. Besides strike-through speed, also evaluate hand feel, processing stability and practical dosage.
When multi-use hydrophilicity matters
Hygiene products such as diapers and sanitary napkins often require repeated liquid strike-through. During screening, compare multi-strike time, additive migration and surface performance.
Recommended validation path
Confirm the nonwoven type and basis weight first, then run small-scale trials comparing different additives and add-on conditions. Need help validating a formulation? Book a trial.
