Adult disposable diapers are worn by adults for a variety of reasons. In the medical world they are called adult absorbent briefs, rather than diapers. This because the word diaper can have negative connotations involved when used in association with adults. People who have a medical condition which makes them unable to have control of urine or feces will wear these briefs. The usage of these disposable diapers or briefs can be a source of embarrassment. These products will often be marketed under names such as incontinence pads or briefs.These diapers are usually made in one of two ways. With tape on the sides to fasten the Adult Diaper or in a pull-up version which is more like underwear. The adult disposable diaper that fastens on the sides will be used for the adult who is confined to bed or who has limited ability to change the brief themselves.The history of the disposable adult diaper has evolved greatly through this century. The first adult diaper consisted of sheets of tissue paper inside of pair of rubber pants. The first type of Adult Diaper was introduced in the United States in 1949 by the Johnson and Johnson Company. These cloth type diapers underwent constant change and improvement from 1949 until the late 1970’s. These improvements included tape that could be reused. Changes in the shapes to reduce the bulging in the crotch area, and the introduction of super absorbent material built into the disposable diaper. They have also included the pull up variety which is very thin and very absorbent. These diapers have a layered structure which allows a transfer and distribution to an absorbent core structure allowing the users of the products to feel dry longer. It is common practice now for an adult diaper to have a chemically activated wetness indicator strip that will change colors when the diaper is wet. Thus preventing waste by having to check the diaper frequently and compromising the tape. Care of adult disposable diapers is minimal and usually consists of keeping them in a clean and dry area before use.
