  • Method for making high bulk wet-pressed tissue
    Patent number: 6350349
    Abstract: Cellulosic webs, such as tissue webs, can be dewatered to consistencies of about 70 percent or greater in a high intensity extended nip press 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.
