MULTILAYER THROUGH-AIR DRYER FABRIC

摘要

A multilayer through-air dryer fabric (10) architecture having a single warp yarn system (12) with a maximum warp fill and a weft yarn system (14) comprised of two sets of weft yarns selecte d to set the warp yarn height above the weft yams without embedment into the fabric plane, the warp and weft yarns interlacing to form diagonal apertures within the fabric to produce a high fabric air permeability for providing increased paper sheet bulk without compromising paper machine running parameters. A method of using the through-air dryer fabric for forming a paper sheet having increased bulk and a predetermined embossed pattern. Also, a method for manufacturing a through-air dryer fabric to provide increased bulk and a predetermined embossed pattern of the paper sheet (20).
