Question:

Fabric with high thread count is:
(A) Water repellent
(B) With better permeability
(C) Fire retardant
(D) With reduced seam ravelling
(E) With increased seam ravelling
Choose the correct answer from the options given below:

Show Hint

To solve this quickly, eliminate (B) because a high thread count restricts air and water passage, decreasing permeability.
This rules out options (A) and (B), helping you find the correct answer.
  • (A), (B) and (D) only.
  • (A), (B) and (C) only.
  • (C), (D) and (E) only.
  • (A), (C) and (D) only.

The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Thread count (or fabric count) is the total number of warp and weft yarns packed into one square inch of fabric.
A high thread count indicates a dense, tightly packed fabric structure, which affects its physical properties.

Step 2: Detailed Explanation:

Let us evaluate how a high thread count affects fabric properties:
- (A) Water repellent: Because the yarns are packed tightly together, the spaces between them (pores) are very small.
This high density makes it difficult for water droplets to penetrate the fabric, providing natural water repellency. Thus, (A) is correct.
- (B) Better permeability: A tight weave restricts the flow of air and moisture.
This means a high thread count decreases permeability rather than improving it. Thus, (B) is incorrect.
- (C) Fire retardant: Tightly packed fabrics contain less trapped air (oxygen) within their structure than loose, open-weave fabrics.
This lack of oxygen makes them more resistant to ignition and slower to burn, giving them better natural fire retardancy. Thus, (C) is correct.
- (D) Reduced seam ravelling: In a dense weave, the yarns are locked tightly in place by friction.
This tight structure prevents the yarns from slipping, fraying, or ravelling at cut edges and seams. Thus, (D) is correct.
- (E) Increased seam ravelling: This is the opposite of (D) and is incorrect.
Therefore, statements (A), (C), and (D) are correct.

Step 3: Final Answer:

A high thread count fabric is water repellent, has better fire retardancy, and exhibits reduced seam ravelling, corresponding to option (D).
