Microscopic examination of two 'cotton' topsheets revealed completely different fiber architectures: one used a hydrophilic treatment for rapid strike-through, the other used a hydrophobic gradient for surface dryness. Both market as cotton topsheet. The engineering reality beneath the marketing label is what determines whether a baby feels wet or dry.
Topsheet Microstructure
Both called cotton topsheet — one wicks liquid down, the other keeps skin dry.
