Step 1: Understanding drapability.
Drapability is the ability of a fabric to fall into graceful folds. Fibers with fine, smooth, and flexible structure have higher drapability.
Step 2: Ranking fibers.
- Silk has the highest drapability due to its smooth filament structure.
- Wool has good drapability because of its crimp and elasticity.
- Cotton has moderate drapability.
- Flax (linen) is stiff, giving the lowest drapability.
Step 3: Conclusion.
The order from high to low is D (Silk) → C (Wool) → A (Cotton) → B (Flax).
