← HistoryWhich outcome resulted from excessive silk weighting in 19th-century textiles?
A)Increased fabric tensile integrity
B)Accelerated fabric structural degradation✓
C)Enhanced dye colorfastness over time
D)Improved resistance against microorganism attacks
💡 Explanation
Fabric damage grew because metallic salts used in weighting, like tin and lead, catalyze the hydrolytic breakdown of silk fibroin polymers via ACID HYDROLYSIS; therefore, the weighted silk decomposes quicker rather than other silk treated solely with dyes.
