Reason (R) : It is a cut pile hence more surface area to absorb water.
Code :
Assertion (A) Analysis: Terry Towel Absorbency
The assertion states that a Terry Towel is the most absorbent fabric structure. Terry cloth is specifically designed for high absorbency due to its characteristic structure of uncut loops. These loops increase the surface area significantly, allowing the fabric to hold a large amount of liquid. Therefore, the assertion that Terry Towels are highly absorbent is correct.
Reason (R) Analysis: Fabric Structure and Absorption
The reason provided is that Terry Towel is a cut pile fabric, leading to more surface area for water absorption.
- Terry cloth is characterized by its loops, not cut pile. These loops are essential for its absorbent properties.
- Cut pile fabrics, where the loops are cut, have a different texture and absorbent quality (e.g., velvet).
- While cut pile can increase surface area, the primary reason for a Terry Towel's exceptional absorbency lies in its specific loop structure, not a cut pile structure.
Therefore, the reason stating it is a 'cut pile' is incorrect.
Conclusion
Based on the analysis:
- Assertion (A) is correct.
- Reason (R) is incorrect.
This aligns with Option 3: (A) is correct, but (R) is incorrect.
