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.
Cotton wool -- absorbent cotton -- absorbs water, and would not shrink.
Yes, combed cotton will shrink slightly if you wash it in warm water and dry all the way through.

Cotton balls shrink when absorbing water because the water molecules cause the cotton fibers to swell and become more tightly packed together. As a result, the fibers contract in size, leading to the overall shrinkage of the cotton ball.
No the cotton will not shrink in your dryer
It gets it wet. If you don't dry it correctly, cotton cloth can shrink...but water itself won't do anything to cotton fiber.
If the soccer jersey is made out of polyester it is not going to shrink. If the jersey is made out of cotton washing in hot water will shrink it.
Yes, Egyptian cotton can and does shrink. In order to avoid this, make sure you do not watch your Egyptian cotton in hot water. You also will want to allow the cotton to air dry and avoid using a drying machine.
Cotton twill does shrink a little when first laundered. If you are using cotton twill to sew clothing you should launder it first to allow it to shrink before you begin. The amount of shrinkage you get depends on if you wash the fabric in hot, warm or cold water.
all you have to do is soak your pants and throw them in the dryer. Also,100% cotton pants will shrink better than 90% cotton or lower pants.
Anything with cotton in it will shrink some if it has not been preshrunk. The amount it will shrink depends on the percentage of cotton in the material. The more polyester the material has the less it will shrink.
Wash it and dry it both on high heat and for more shrinkage soak in hot water
