← HistoryWhich consequence results when drawloom silk threads experience excessive hygroscopic expansion?
A)Reduced dye uptake uniformity
B)Tangential stress exceeding fiber strength
C)Accelerated enzyme degradation process
D)Weave structure dimension instability✓
💡 Explanation
Dimension instability occurs if silk absorbs high moisture because the threads undergo hygroscopic expansion generating stress, causing weave deformation on the drawloom. Therefore, structure changes rather than color shifts are triggered, rather than direct molecular decomposition.
