  • Patent number: 8398820
    Abstract: A method of making a belt-creped absorbent cellulosic sheet includes compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber, applying the nascent web having the apparently random fiber distribution to a translating transfer surface that is moving at a transfer surface speed, belt-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping belt, the belt-creping step occurring under pressure of at least 20 pounds per linear inch in a belt creping nip defined between the transfer surface and the creping belt. The belt is traveling at a belt speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping belt.

  • Patent number: 8257551
    Abstract: A soft, layered, single-ply wet-pressed tissue can be made with improved softness by providing one or both outer layers of the tissue with polysiloxane-treated pulp fibers. A particularly suitable wet-pressing process includes pressing a wet tissue web between a felt and a transfer belt to dewater the web, followed by transfer of the dewatered web to a texturizing fabric where the wet web is provided with a three-dimensional texture. Thereafter the texturized web is transferred to a Yankee dryer, dried and creped. The combination of the polysiloxane fibers and the texturizing step provides a particularly effective combination of surface feel, low stiffness and high bulk (caliper).

  • Patent number: 7967951
    Abstract: An object of the present invention is to provide an embossed crepe paper which can clearly be formed into fine embossed shapes, and is excellent in the fluffy feel and therefore excellent in such as absorbency for fats. As a means of achieving this object, the method for manufacturing an embossed crepe paper, according to the present invention, is a method for manufacturing an embossed crepe paper comprising a step of embossing a raw crepe paper, wherein: a raw paper having a basis weight of 6 to 28 g/m2 is used as the raw crepe paper; and the embossing step includes the steps of: (a) supplying the raw crepe paper with water in an amount of 0.1 to 100 weight % based on the basis weight to thereby put the raw crepe paper in a wet condition; (b) embossing the wet-conditioned raw crepe paper; and (c) drying the embossed wet-conditioned raw crepe paper.

  • Patent number: 7935220
    Abstract: A process for making absorbent cellulosic paper products such as sheet for towel, tissue and the like, includes compactively dewatering a nascent web followed by wet belt creping the web at an intermediate consistency of anywhere from about 30 to about 60 percent under conditions operative to redistribute the fiber on the belt, which is preferably a fabric. In preferred embodiments, the web is thereafter adhesively applied to a Yankee dryer using a creping adhesive operative to enable high speed transfer of the web of intermediate consistency such as a poly(vinyl alcohol)/polyamide adhesive. An absorbent sheet so prepared from a papermaking furnish exhibits an absorbency of at least about 5 g/g, a CD stretch of at least about 4 percent, and an MD/CD tensile ratio of less than about 1.1, and also exhibits a maximum CD modulus at a CD strain of less than 1 percent and sustains a CD modulus of at least 50 percent of its maximum CD modulus to a CD strain of at least about 4 percent.
