Hint:

Focus on what moves in dyeing machinery: - Jigger: Fabric moves, liquor is stationary. - Package/Beam: Fabric is stationary, liquor is pumped through it. - Winch: Fabric moves, liquor is mostly stationary. - Jet: Both fabric and liquor move.

Answer 1

The Correct Option is A

Step 1: Analyze the principle of each dyeing machine. The main distinction is what moves: the textile, the dye liquor, or both. 
- A. Tub dyeing (Winch/Beck dyeing): The fabric, in a rope form, is moved through a relatively stationary bath of dye liquor. However, in the most basic "tub dyeing" sense (like manual dyeing in a tub), both can be considered stationary with manual agitation. Given the other options, this is the most likely candidate for stationary material and liquor. 
- B. Jigger dyeing: The fabric in open width is passed back and forth from one roller to another through a small trough of stationary dye liquor at the bottom. The textile material moves through the stationary liquor. 
- C. Package dyeing: Yarn is wound onto a perforated package. The package itself remains stationary. The dye liquor is forcefully pumped through the stationary textile package. 
- D. Jet dyeing: The fabric, in a rope form, is transported by a high-velocity jet of the dye liquor itself. Therefore, both the textile material and the dye liquor are moving simultaneously.

Step 2: Re-evaluate 'Tub dyeing'. In a Winch machine, the fabric rope is pulled over a winch reel and falls back into the tub, so the fabric moves. However, compared to a jigger, the liquor is also circulating to some extent. Let's look at the matches. B must be I. C must be II. D must be III. 

- B - I: Jigger dyeing -> Moving the textile material through the stationary dye liquor. (Correct) 

- C - II: Package dyeing -> Pumping the dye liquor through the stationary textile. (Correct) 

- D - III: Jet dyeing -> Moving the textile material and dyeing liquor simultaneously. (Correct) This leaves A to be matched with IV. 

- A - IV: Tub dyeing -> Textile materials and dye liquor are stationary. This is the best fit among the choices, representing a simple immersion process without forced circulation of either component.

Step 3: Assemble the combination. A-IV, B-I, C-II, D-III. This corresponds to option (A).
