Abstract
Fibrous absorbent webs having a low density (about 0.01 g/cm.sup.3 to about 0.15 g/cm.sup.3) and comprising at least about 50% hydrophilic microfibers, such as cellulose microfibers, having a diameter of from about 0.01 microns to about 15 microns possess superior absorption properties, especially under typical usage conditions. Hydrophobic microfibers may also be used, provided such fibers are hydrophilized before or after web formation.
