Question

why cleaning of wool is necessary​

Answer 1

Explanation:

To avoid the roughness

Answer 2

Answer:

Caring for wool is actually much easier than you might think. Wool as a fibre keeps itself clean naturally, expelling odours through moisture control, and is naturally stain and wrinkle resistant. This means you shouldn't have to wash your woollies as often.
