The diaper is a cloth that is worn by an individual to collect waste excretions from the urinary and anal areas. A diaper usually consists of a thin or thick outer layer made from plastic, cloth, pulp, or paper. The ends of the pants are sealed together with either adhesive tapes or safety pins on adult diapers and elastic bands on training pants.

A diaper is a soft toweling/cloth worn by babies, children, and incontinent adults for the purpose of containing urinary or fecal incontinence. The diaper has an opening in the middle which is placed over the genitalia. They are fastened with fasteners such as tapes or a pin. Diapers are used typically when the wearer is unable or unwilling to use a toilet. Using a diaper can help keep clothing clean.

Currently, there are three types of disposable diapers on the market: regular, premium, and eco-friendly diapers. Regular diapers are made up of fluff pulp mixed with a super absorbent polymer, have a plastic outer shell, and are the least expensive. Premium diapers have “all-around barriers” to help keep babies dry longer, thicker cores for increased comfort and absorption, softness inside and out, stretchy waistbands for fit and comfort, refastenable tapes that pull from front to back for a snug fit, and they are made of biodegradable materials.

Although Eco-friendly diapers are those that use little or no chemicals in their production process. Usually, these diapers have a low absorbency level, which is preferred by some parents as these diapers may require more frequent changes. Some eco-friendly diapers may be made out of recycled materials.

Diapers offer benefits such as helping keep the wearer clean and dry, allowing design flexibility, and they can be used for cost-saving purposes. Additionally, diapers can help minimize the public embarrassment of the wearer by containing any accidents that may occur. Furthermore, if a person is no longer able to hold their bladder, they can use diapers to minimize the number of changes needed.
