Abrégé
(EN)
Cellulosic webs, such as tissue webs, can be dewatered to consistencies of about 70 percent or greater in a high intensity extended nip press (20) while retaining a substantial amount of bulk. While webs intended for use as tissues containing conventional furnishes become overly densified when passed through a high intensity extended nip press, furnishes containing certain types of fibers, such as chemically cross-linked or heat-treated fibers, resist compression and allow the compressed web to retain a high level of bulk after a high degree of dewatering.
