Question

Sequence of steps for production and processing of Silk yarn.
A. Reeling
B. Stifling and Brushing
C. Degumming
D. Throwing
Choose the correct answer from the options given below:

• A. A, B, D, C
• B. A, C, B, D
• C. B, A, D, C
• D. C, B, D, A

Hint:

Silk processing order: Stifling → Reeling → Throwing → Degumming.

Answer 1

The Correct Option is C

Step 1: Stifling and brushing.
Freshly harvested cocoons are stifled (killed) and brushed to locate the filament end. Hence B comes first.
Step 2: Reeling.
The silk filament is unwound (reeled) from cocoons to form raw silk. Hence A comes second.
Step 3: Throwing.
The raw silk filaments are twisted together (throwing) to provide strength for weaving. Hence D follows.
Step 4: Degumming.
Finally, sericin (gum) is removed by boiling with soap solution, leaving lustrous silk. Hence C is last.
Step 5: Conclusion.
The correct sequence is B → A → D → C.
