What Happens to My Wool Sweater in the Washer?

The video explains why wool sweaters shrink or get damaged in washing machines. It highlights the biochemistry of wool, which is made of protein, and how modern detergents contain enzymes that break down proteins, leading to damage. The structure of wool, with its cuticles, also contributes to shrinkage when agitated in water. To prevent damage, it's advised to wash wool in cold water with suitable detergents or opt for dry cleaning.
