Abstract
Abstract Diapers are woven with a central panel comprising warp yarns which are a blend of hydrophobic fibers and hydrophilic fibers. Unlike yarns which are composed entirely of hydrophobic fibers, blended yarns of this type may be readily processed by conventional means through the slashing, weaving, and scouring processes. The central panel thus produced will, in use, remain dryer than panels composed entirely of hydrophilic yarns.
