Question

Match List - I with List - II.

List - I (Fibre)	List - II (Speciality)
A. Viscose B. Silk C. Wool D. Polynosic	I. Dimensional stability II. Scales on the surface III. Artificial silk IV. Directional lustre

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

Hint:

Fiber Identifiers: Wool = Scales. Silk = Prism-like shine. Viscose = The first "Art Silk." Polynosic = The stable version of Rayon.

Answer 1

The Correct Option is B

Concept: Textile fibers are often identified or categorized by unique physical surface features or historical designations.

Step 1: Matching Regenerated Fibers.
Viscose was historically marketed as Artificial silk (III) due to its shine. Polynosic (a modified viscose) was developed specifically to have higher Dimensional stability (I), especially when wet.

Step 2: Matching Natural Fibers.
Silk is famous for its triangular cross-section that produces a unique Directional lustre (IV). Wool is unique among fibers for having microscopic Scales (II) on its surface, which lead to felting.

Step 3: Final Matching.
The resulting match is: A-III, B-IV, C-II, D-I.
