Question

Assertion (A): Natural fibre fabrics, such as cotton and linen, can shrink when laundered in hot water.

Reason (R): The heat from hot water can cause the natural fibres to contract, leading to shrinkage in the fabric.

पर्याय

• A is true, but R is false.

• A is false, but R is true.

• Both A and R are true, and R is the correct explanation of A.

• Both A and R are true, and R is not the correct explanation of A.

Answer 1

Both A and R are true, and R is the correct explanation of A.

Explanation:

The assertion is true because natural fabrics like cotton and linen shrink when washed in hot water. The reason is also true and explains it perfectly because hot water relaxes the tight tensions placed on the fibres during manufacturing. This thermal relaxation causes the natural cellulose fibres to contract and return to their shorter, original state, leading to overall fabric shrinkage.
