Which material weakness arises when Byzantine silk robes experience repeated saturated wet-dry cycles?

💡 Explanation

Hydrolytic chain scission weakens silk because water molecules break peptide bonds within fibroin proteins, therefore the degradation compounds the mechanical stress, rather than cross-linking, depolymerization at high temperatures, or robust crystalline structure.
