The performance of an absorbent hygiene product depends heavily on the quality and consistency of its raw materials. CAPET provides raw material testing services to help manufacturers verify incoming materials, identify quality variations, and maintain consistent production standards
● Strike‑through / acquisition time: how quickly fluid passes through to the absorbent core (DI water, 0.9% NaCl, synthetic urine).
● Rewet / rewet under load: liquid returned to surface after compression.
● Surface wicking/spread (lateral distribution): how fluid spreads across the topsheet.
