A lump of cotton and wool shrinks in water due to the absorption of moisture. Both materials are made of natural fibers that can absorb water, causing them to swell and alter their structure. When the fibers absorb water, they can become saturated and lose some of their original shape, leading to a perceived shrinkage as the fibers contract during drying or upon release of moisture. Additionally, the heat from washing or drying can further cause fibers to tighten, contributing to the shrinking effect.

Why does Cotton lump shrink in water?
Cotton shrinks in water for two main reasons. 1. Cotton (and wool, silk, etc.) swell up when they come in contact with water because they absorb water. They subsequently shrink when the water is removed from them. This is called water regain. Cotton has the fifth highest water regain (with wool having the most). 2. When agitated, such as when hand/machine washed (much more apparent in machine washing), the cotton fibres are forced together, packing more closely, which gives the overall effect of shrinking the cotton.
