The Correct Option is D
Solution and Explanation
Concept:
In sizing quality control (SQC), viscosity of the size liquor is a critical parameter because it directly affects penetration, coating, and adhesion on warp yarn. Zaun cup is a simple flow cup viscometer used to measure viscosity based on flow time.
Step 1: Understand Zaun cup function.
It measures flow rate of liquid size.
Step 2: Relate to property.
Flow time is directly related to viscosity. \[ \text{Longer flow time} \Rightarrow \text{Higher viscosity} \]
Step 3: Evaluate options.
Only viscosity matches flow-based measurement.
Step 4: Final answer selection.
\[ \boxed{\text{Viscosity}} \] Thus, \[ \boxed{\text{Option (D) is correct.}} \]
