- Jigger
- Pad Batch
- Jet
- Winch
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
K/S value represents color strength in dyed fabrics based on Kubelka–Munk theory. Higher K/S indicates higher dye absorption and deeper shade.
Step 1: Understand dyeing methods.
• Jigger → moderate dye penetration
• Jet → rapid but moderate fixation
• Winch → rope dyeing, less uniform
• Pad batch → long dwell time + high fixation
Step 2: Analyze K/S trend.
Higher K/S (10) indicates:
• Maximum dye fixation
• Long reaction time
• High exhaustion efficiency
Step 3: Match method.
Pad batch dyeing provides:
• High dye fixation
• Uniform deep shades \[ \boxed{\text{Pad Batch}} \] Thus, \[ \boxed{\text{Option (B) is correct.}} \]
