Question

Match List - I with List - II.

List - I	List - II
A. Knitted Fabric B. Crease Recovery C. Stiffness D. Water repellency	I. Contact Angle II. Bursting strength test III. Dimensional stability IV. Bending modulus

• A. A-II, B-III, C-IV, D-I
• B. A-II, B-III, C-I, D-IV
• C. A-II, B-I, C-III, D-IV
• D. A-I, B-II, C-III, D-IV

Hint:

For fabric matching: 'Bursting' is for stretchy knits, 'Modulus' is for stiffness, and 'Contact Angle' is the standard for hydrophobic/water-repellent surfaces.

Answer 1

The Correct Option is A

Concept: Fabric testing assesses the performance and comfort characteristics of textiles. Each property has a specific mechanical or physical test designed to simulate real-world usage.

Step 1: Analyzing Mechanical and Surface Properties.
Knitted fabrics, due to their structure, are typically tested for Bursting strength rather than tensile strength. Water repellency is measured by the Contact Angle a water droplet forms on the fabric surface.

Step 2: Analyzing Aesthetic and Stability Properties.
Crease recovery is a measure of a fabric's Dimensional stability after being folded or crushed. Stiffness is a physical property related to the fabric's resistance to bending, quantified by the Bending modulus.

Step 3: Matching the Lists.
A-II (Knitted: Bursting), B-III (Crease: Dimensional stability), C-IV (Stiffness: Bending modulus), D-I (Water repellency: Contact Angle).
