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.
