The more water is available, the more the polymer has to unwind to get it. Each link gets larger as it hooks up to more and more water. The chain begins to swell on the outside surface and that allows more water to get farther into the polymer to available link points. Water is cross-linked farther in and the polymer expands to make room for it.
