Question

Match List I with List II

Choose the correct answer from the options given below:

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

Hint:

Textile Defects:
Frosting $\rightarrow$ Color loss by abrasion.
Tendering $\rightarrow$ Chemical fabric weakening.
Barre $\rightarrow$ Horizontal stripe defect.
Metamerism $\rightarrow$ Color shift under different lights.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Textile testing and quality assurance terminology for color and structural fabric defects.

Step 2: Detailed Explanation:
Matching textile defects and phenomena in List I with their definitions in List II:
- A. Frosting: IV. Change of colour due to localised abrasive wear (especially in blended cross-dyed fabrics where one fiber abrades away).
- B. Tendering: I. Weak areas in the fabric resulting from a chemical change (acid/alkali degradation or photo-oxidation).
- C. Barre: II. Horizontal off shade band across the fabric in knits/wovens caused by yarn tension or count variations.
- D. Metamerism: III. The same colour appears different under different light sources (e.g., matching in daylight but mismatching under incandescent light).
Matching sequence: A - IV, B - I, C - II, D - III.

Step 3: Final Answer:
Hence, the correct matching is A - IV, B - I, C - II, D - III, corresponding to option (B).
