Question

Match List - I with List - II (Spinning Process Stages).

List - I	List - II
A. Combed drawn sliver	I. Auto Winding
B. Roving	II. Simplex
C. Yarn Cone	III. Ring Frame
D. Yarn	IV. Drawing

Choose the correct answer from the options given below :

• A. \( \text{A-IV, B-II, C-I, D-III} \)
• B. \( \text{A-III, B-II, C-I, D-IV} \)
• C. \( \text{A-IV, B-I, C-II, D-III} \)
• D. \( \text{A-III, B-I, C-II, D-IV} \)

Hint:

Process Flow: Carding/Combing $\rightarrow$ Drawing $\rightarrow$ Simplex (Roving) $\rightarrow$ Ring Frame (Yarn) $\rightarrow$ Winding (Cones). Each step makes the material thinner!

Answer 1

The Correct Option is A

Concept: Fiber-to-yarn conversion involves a sequential series of processes where fibers are cleaned, aligned, and reduced in diameter through "drafting." Each stage produces a specific intermediate product.

Step 1: Mapping products to machinery:
• Combed drawn sliver (A): After fibers are combed, they are passed through a Drawing (IV) frame to blend and align them into a uniform sliver.
• Roving (B): The sliver is drafted further and given a slight twist to form roving on a machine known as the Simplex (II) or speed frame.
• Yarn Cone (C): Small yarn packages (bobbins) are wound onto larger, high-density cones during the Auto Winding (I) stage.
• Yarn (D): The final transformation of roving into fine, highly twisted yarn takes place on the Ring Frame (III).

Step 2: Correct Sequence: The matching pairs are A-IV, B-II, C-I, and D-III, matching option (1).
