The purpose of a diaper is to absorb moisture and contain mess so that the wearer can remain dry and comfortable after wetting or soiling themselves. When diapers become full and can no longer hold any more waste, they require changing; this process is often performed by a secondary person such as a parent or caregiver. Failure to change a diaper on a regular enough basis can result in diaper rash.
In the 20th century, the disposable diaper gradually evolved through the inventions of several different people. In 1942, a Swedish paper company known as PauliStróm created the first disposable diaper using sheets of tissue placed inside rubber pants.
