Question

Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Polyester fabric possesses wash and wear characteristic. Reason (R): Polyester exhibits high crease recovery and poor moisture absorption. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

To test if a Reason (R) explains an Assertion (A), read them together using "because": "Polyester is wash-and-wear because it has high crease recovery and low moisture absorption." If it sounds logically sound, (1) is your answer.

Answer 1

The Correct Option is A

Concept: "Wash and wear" refers to a fabric's ability to be laundered and then worn immediately without the need for ironing. This characteristic depends on how the fabric maintains its shape and dries.

Step 1: Analyzing Assertion (A).
Polyester is well-known in the textile industry for its "wash and wear" properties. It is a synthetic fiber that is highly resilient and maintains its pressed shape even after several washes. Thus, (A) is correct.

Step 2: Analyzing Reason (R).
The "wash and wear" property is a direct result of two physical characteristics:
• High Crease Recovery: Polyester fibers are elastic and return to their original shape after being bent, preventing wrinkles during the wash cycle.
• Poor Moisture Absorption: Polyester is hydrophobic. Because it doesn't absorb much water, it doesn't swell during washing and dries extremely quickly. Thus, (R) is correct.

Step 3: Evaluating the Relationship.
Because high crease recovery keeps the fabric smooth and poor absorption leads to fast drying, these factors together enable the "wash and wear" characteristic. Therefore, (R) is the correct explanation for (A).
