Abstract
Abstract An improved washable diaper is provided with an absorbent liner that is folded within the diaper during use for improved absorbency and, following use, extends from the diaper for improved efficiency of cleaning and drying. An additional liner may be secured to the liner in cases where extra absorbency is required, such as for overnight use, and removed from the liner for cleaning and drying. The liners provide additonal layers of absorbent cloth while their separation from the diaper body following use avoids the difficulties of cleaning and drying presented by a number of cloth layers permanently secured to one another.
