  • Publication number: 20150144158
    Abstract: A method of cleaning residue from a surface includes providing a disposable cellulosic wiper including a percentage by weight of pulp-derived papermaking fibers, and a percentage by weight of regenerated independent cellulosic microfibers having a number average diameter of less than about 2 microns and a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml. The microfibers are selected and present in amounts such that the wiper exhibits an average effective pore radius of less than 50 microns. The wiper is applied, with a predetermined amount of pressure, to a residue-bearing surface. The surface is wiped with the applied wiper, while applying the predetermined amount of pressure, to remove residue from the surface, such that the surface has less than 1 g/m2 of residue after being wiped under the predetermined amount of pressure.

  • Publication number: 20150000851
    Abstract: A method of making a wiper/towel product includes compactively dewatering a nascent web having cellulosic microfibers and an apparently random fiber distribution. The dewatered web is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a polymeric creping belt having perforations. The belt-creping step occurs under pressure in a belt creping nip. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the domed regions.

  • Publication number: 20140367062
    Abstract: A multi-ply bath tissue includes a first ply providing a first surface of the bath tissue. The first ply includes first and second layers. The first layer of the first ply forms the first surface. The first layer of the first ply includes a temporary wet strength resin. The second layer of the first ply is substantially free from a temporary wet strength resin. A second ply provides a second surface of the bath tissue. The second ply includes first and second layers. The first layer of the second ply forms the second surface. The first layer of the second ply includes a temporary wet strength resin. The second layer of the second ply is substantially free from a temporary wet strength resin. The bath tissue has a CD wet tensile strength of between about 55 grams to about 75 grams.

  • Patent number: 8877008
    Abstract: A multi-ply bath tissue that is both soft and durable. The multi-ply bath tissue can include first and second plies, each of which includes two layers. A temporary wet strength resin is provided in the layers of the first and second plies that form the surfaces of the bath tissue. The bath tissue has an excellent combination of low wet abrasion and CD wet tensile, and softness that is demonstrably better than comparative products.

  • Patent number: 8864944
    Abstract: A method of making a multi-ply wiper/towel product with cellulosic microfibers. The method includes compactively dewatering a nascent web that includes at least about 10% fibrillated cellulosic microfibers and has an apparently random distribution of fibers. The dewatered web having the apparently random distribution of fibers is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a creping belt. The belt-creping step occurs under pressure in a belt creping nip defined between the transfer surface and the creping belt. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the dried web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof.
