Abstract
A low density compression resistant cellulosic-based nonwoven fabric having good absorbency and et tensile strength is formed from cellulosic-based fibers which are treated for use in an air laid process, with an aqueous dispersion of a self-crosslinkable polymeric binder and a chemical stiffening agent for the cellulose fibers and then dried at temperatures that result in intrafiber crosslinking and interfiber binding. The cellulosic-based nonwoven fabrics, thus formed, are useful in personal care products such as diapers and feminine care products.
