Question

The step-by-step process followed to produce silk filament fibre from the cocoon is as follows:
• [A.] Degumming
• [B.] Sorting
• [C.] Stifling
• [D.] Reeling
• [E.] Throwing Choose the correct answer from the options given below :

• A. \( \text{C, B, D, E, A} \)
• B. \( \text{B, C, D, A, E} \)
• C. \( \text{D, C, E, B, A} \)
• D. \( \text{C, D, B, E, A} \)

Hint:

Remember: Stifling must happen before reeling, or the moth will bite its way out and ruin the continuous filament. Degumming is what gives silk its famous luster.

Answer 1

The Correct Option is B

Concept: Silk production (sericulture) involves carefully killing the pupa and unwinding the long, continuous protein filament from the cocoon.

Step 1: Mapping the production sequence:
• Sorting (B): Cocoons are categorized by color, size, and shape.
• Stifling (C): Heat is applied to kill the pupa inside to prevent it from breaking the filament.
• Reeling (D): Finding the end of the filament and unwinding it onto a reel.
• Degumming (A): Removing the natural sericin (silk gum) to reveal the shine and softness.
• Throwing (E): Twisting multiple silk filaments together to create a usable yarn.

Step 2: Final Matching: Following the industrial workflow, the sequence is B-C-D-A-E, matching option (2).
