Question

The sequence of machines for flow of cotton in ring spinning process is:
A. speed frame
B. blow Room
C. carding
D. draw frame
E. ring frame Choose the correct answer from the options given below :

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

Hint:

The standard acronym to remember is B-C-D-S-R: Blowroom $\rightarrow$ Carding $\rightarrow$ Drawing $\rightarrow$ Speed frame $\rightarrow$ Ring frame.

Answer 1

The Correct Option is D

Concept: The ring spinning process is a series of thinning and cleaning operations that transform raw cotton into yarn.

Step 1: Opening and Cleaning.
Raw cotton from bales is first opened and cleaned in the B (Blow Room). The output is then fed to C (Carding) to individualize the fibers and remove fine trash.

Step 2: Leveling and Thinning.
The carded sliver is processed in the D (Draw frame) to improve uniformity. The resulting sliver is then thinned into "roving" on the A (Speed frame).

Step 3: Final Spinning.
The roving is finally fed into the E (Ring frame), where it is drafted to its final fineness and twisted into yarn.
