I think it's more to do with how cotton behaves when moist. It loses it's 'spring' and goes floppy, and hence the strands tend to stick to one another, and the vital air gaps disappear. That then also inhibits evaporation. Materials that keep their spring when damp allow the air gaps to remain so are better at evaporating moisture, and of course they don't flatten as much as damp cotton.1 point
