  • Patent number: 10626557
    Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85° after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.

  • Patent number: 10544596
    Abstract: An anti-slip, liquid management cover article for a flooring surface. The article includes a film defining a working face. A microstructured surface is formed at the working face, and includes a plurality of primary ridges and capillary microchannels each having a bottom surface. Each primary ridge is an elongated body having a length. A shape of a portion of at least one of the primary ridges is non-uniform in a direction of the length. The capillary microchannels facilitate spontaneous wicking of liquid. With this construction, the non-uniform shape establishes an elevated coefficient of friction at the working face as measured in multiple directions. The cover article minimizes the risk of pedestrian slippage, even in the presence of water or other liquids.

  • Patent number: 10040265
    Abstract: The novel tissue products of the present invention are generally produced by calendering a tissue basesheet using at least one patterned roll. In one embodiment the patterned roll replaces the flat steel roll commonly used in calendering. The elements on the patterned roll provide a means of providing a nip having variable loading such that Z-direction variability in the web is reduced, yielding a smoother web, but without subjecting the web to excessive compression forces and preventing excessive caliper loss. Thus, webs converted according to the present invention tend to retain a greater percentage of their caliper and bulk when converted compared to webs converted using conventional calendering means.

    Abstract: A method of making a cellulosic absorbent sheet. A cellulosic web is prepared from an aqueous papermaking furnish. The web is fabric-creped. The fabric-creping step forms a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights including at least: (i) a plurality of fiber-enriched regions of a relatively high local basis weight, interconnected by way of (ii) a plurality of lower local basis weight linking regions. The drawable reticulum includes a cohesive fiber matrix capable of increasing in void volume upon drawing. The creped web is dried, while substantially preserving the drawable reticulum, to form a dried web, and the dried web is drawn. The drawing step increases the bulk of the dried web.

  • Patent number: 8562786
    Abstract: A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a translating transfer surface and is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric. The creping fabric travels at a fabric speed that is slower than the speed of the transfer surface. The nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The creped web is dried to form a dried web, and the dried web is drawn. The drawing step includes drawing the dried web between a first draw roll and a second draw roll.
