Other common features of disposable diapers include one or more pairs of either adhesive or mechanical fastening tapes to keep the diaper securely fastened. Some diapers have tapes which are refastenable to allow adjusting of fit or reapplication after inspection. Elasticized fabric single and double gussets around the leg and waist areas aid in fitting and in containing urine or stool which has not been absorbed. Some diapers lines now commonly include wetness indicators, in which a chemical included in the fabric of the diaper changes color in the presence of moisture to alert the carer or user that the diaper is wet.[20] A disposable diaper may also include an inner fabric designed to hold moisture against the skin for a brief period before absorption to alert a toilet training or bedwetting user that they have urinated. Most materials in the diaper are held together with the use of a hot-melt adhesive, which is applied in spray form or multi lines, an elastic hot melt is also used to help with pad integrity when the diaper is wet.

Cloth diapers are reusable and can be made from natural fibers, synthetic materials, or a combination of both.[21] They are often made from industrial cotton which may be bleached white or left the fiber's natural color. Other natural fiber cloth materials include wool, bamboo, and unbleached hemp. Man-made materials such as an internal absorbent layer of microfiber toweling or an external waterproof layer of polyurethane laminate (PUL) may be used. Polyester fleece and faux suedecloth are often used inside cloth diapers as a "stay-dry" wicking liner because of the non-absorbent properties of those synthetic fibers.


There are several different organizations around the country that distribute free diapers to needy and low income families. Many of these are charities or churches, with some government programs also assisting. There are programs for single mothers, teenage moms, and families living in poverty. Anyone that needs free or low cost diapers near where they live, and that meets qualifications, may apply.
