Which mechanism causes structural weave instability in Byzantine silk tapestries exposed to elevated humidity?

💡 Explanation

Hygroscopic fiber expansion induces weave instability because silk fibers absorb ambient moisture, therefore the weave structure distorts rather than remaining rigid; protein hydrolysis would degrade individual fibers chemically.
