Why do wool sweaters shrink?
Wool can shrink in the dryer or washer because of the heat and movement. Wool fibers are made out of protein scales. The combination of heat and movement makes the scales expand and catch on each other, which binds the fibers closer together. The closer the fibers get, the more the wool shrinks.

What happens when wool shrinks?
Wool can shrink down significantly from its original size. Agitation makes the scales on the wool fibers rub together. The more they rub, the closer they lock together, making a dense, fuzzy fabric: felt. Felting shrinks wool down, and once the wool is felted, you cannot un-felt it.
Does washing jeans in hot water shrink them?
But if you’re ready to shrink your straight-leg jeans to a smaller size, wash them in the standard washing cycle with your hottest water setting. When this heat is applied to the wet jeans, the cotton fibers will contract as they dry completely, which causes the shrinking effect.

Do synthetic fabrics shrink when wet?

Does cotton shrink more than wool?
Woolen clothes are even more loosely woven, making them much more susceptible to shrinkage than any cotton fabric. Another factor that plays a role in shrinkage is the moisture content of the fabric. In cotton, this is about 5 percent, while in wool, it is 17 percent.
Why does woven wool need to be washed in water?
When wool fibers are processed and woven into fabric, those scales snag each other, and the fiber’s natural alignment is disrupted. Introducing woven wool fabric to water allows those scales to realign themselves. Heat from the dryer tightens up the contact between the fibers in the fabric.
