Abstract

An environmentally sound absorbent insert for use with cloth diapers and the like. The insert comprises a sandwich of first and second webs constructed of non-toxic, biodegradable, pliable, liquid-absorbent material, such as tissue paper, with a layer of non-toxic, biodegradable, liquid-absorbent material sandwiched between them. The sandwich is bonded in an environmentally sound manner, such as by a mechanical bond (such as crimping) or by a non-toxic, biodegradable adhesive. The insert is used by placing it in the diaper so that the absorbent insert is sandwiched between layers of cloth. The cloth acts as a wick to draw fluids from the body of the wearer to the absorbent insert, to be retained until changing. One feature is a process for making the insert via a continuous feed process.
