Abstract

A differential density single lamina web of cellulosic fibers is disclosed, comprising at least two pluralities of micro-regions disposed in a non-random and repeating pattern, a first plurality of high density regions comprising fluid latent indigenous polymers (FLIP) cellulosic fibers and a second plurality of low density regions. A process for making the web comprises providing a plurality of papermaking fibers comprising FLIP; providing a macroscopically monoplanar papermaking belt having a web-facing surface and deflection conduits; depositing the plurality of the cellulosic fibers on the papermaking belt to form a web; heating the web to a temperature sufficient to cause the FLIP contained in a first portion associated with the web-facing surface of the belt to soften; impressing the web-side surface of the belt into the web;
immobilizing the flowable FLIP and creating FLIP-bonds between the fibers comprising the first portion of the web.
