Fig 5. Under conditions of high humidity (60%), a low water loss over time (8 days) was determined (red circled line), while at a lower humidity (30%, red squared line) there was a fast weight loss (after 3 days).

In relation to this, water (blue line) showed a more constant evaporation rate at 60% humidity and likewise reached its final minima after 3 days. Bombyx mori silkworm fibres (green line), watered for 24 h, evaporated within 2 days, showing the highest weight loss within the first 12 h.
