Question

Match List - I with List - II.

List - I	List - II
A. Kevlar	I. PBO
B. Dyneema	II. HDPE
C. Zylon	III. PPS
D. Ryton	IV. Aramid

Choose the correct answer from the options given below :

• A. \( \text{A-III, B-IV, C-I, D-II} \)
• B. \( \text{A-III, B-I, C-IV, D-II} \)
• C. \( \text{A-IV, B-III, C-I, D-II} \)
• D. \( \text{A-IV, B-II, C-I, D-III} \)

Hint:

When solving matching questions for technical fibers, start with the most famous pairings: Kevlar is always Aramid, and Dyneema is always Polyethylene.

Answer 1

The Correct Option is D

Concept: High-performance synthetic fibers are engineered for specific industrial and protective applications based on their unique chemical structures and physical properties.

Step 1: Evaluate the chemical classification of each fiber.

• Kevlar: This is a heat-resistant and strong synthetic fiber related to other nomex and technora. It belongs to the Aramid family (Para-aramid), characterized by rigid polymer chains.
• Dyneema: Known as the world's strongest fiber, it is made from Ultra-High-Molecular-Weight Polyethylene (UHMWPE/HDPE). It is highly resistant to moisture and chemicals.
• Zylon: This is the trade name for PBO (poly(p-phenylene-2,6-benzobisoxazole)). It possesses extremely high tensile strength and thermal stability.
• Ryton: This fiber is composed of Polyphenylene Sulfide (PPS). It is valued for its exceptional chemical and heat resistance in industrial filtration.
