Step 1: Structure of complex yarns.
Complex yarns are made from more than one strand arranged to give decorative effects.
Corded complex yarns typically use three parts: base yarn, effect yarn, and binder yarn.
Step 2: Function of each part.
- Base Yarn: Provides strength and foundation.
- Effect Yarn: Creates surface texture and decorative appearance.
- Binder Yarn: Holds the base and effect yarns together firmly.
- Fancy Yarn: This is not a separate component; it is the general name for decorative yarns.
Step 3: Option analysis.
- Option 1: A, B and D → Incorrect, because "Fancy yarn" is not a distinct component.
- Option 2: A, B and C → Correct, includes the three real components.
- Option 3: A, B, C and D → Incorrect, again includes Fancy Yarn.
- Option 4: B, C and D → Incorrect, misses Base Yarn.
Step 4: Conclusion.
Hence, corded complex yarns consist of Base, Effect, and Binder yarns.
