A disposable cellulosic wiper includes 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 a relative water residue removal efficiency of at least 150% as compared with a like sheet without regenerated independent cellulosic microfibers.

Embodiments of a roll support, and a roll support system, for a sheet product dispenser are disclosed. One such roll support includes an arm having an end portion and an aperture proximate the end portion of the arm and recessed therein. The aperture includes a capture region and a release region. The capture region has a width dimensioned to receive a matching end cap and shaped to allow the matching end cap to rotate freely within the capture region. The release region is contiguous with the capture region and has a width less than the width of the capture region.

A method of cleaning residue from a surface includes providing a disposable cellulosic wiper including a percentage by weight of pulp-derived papermaking fibers. The pulp-derived papermaking fibers have a characteristic scattering coefficient of less than 50 m2/kg. The wiper also includes a percentage by weight of fibrillated 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 a scattering coefficient of greater than 50 m2/kg. The wiper is applied, with a predetermined amount of pressure, to a residue-bearing surface, and the surface is wiped, 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.

A disposable paper towel with an anti-microbial lotion and is provided with a chromatic transfer indicator which undergoes a delayed, visually perceptible color change at a predetermined time after the towel is wetted. An anti-microbial lotion on the towel increases water absorbency times (WAR) to further promote lotion transfer to the skin and increase lotion transfer effectiveness.
摘要:
A method of making a belt-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface moving at a transfer surface speed. The web is belt-creped from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the belt, the belt-creping step occurring under pressure in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the transfer surface speed, and the web is creped from the transfer surface and redistributed on the creping belt to form a web. The web includes hollow domed regions, connecting regions, and transition areas. The web is dried to produce the belt-creped absorbent cellulosic sheet.

An automated dispenser includes a rotatable carousel including a mounting station for a primary roll of sheet product and a mounting station for a reserve roll of sheet product; mounting brackets configured for mounting the carousel such that it is movable between a locked, rearward position for dispensing and a forward position where the carousel is rotatable for reloading; a drive system including a motor coupled to a drive roller and control circuitry; a transfer mechanism adapted so as to be operable to urge a tail of the reserve roll toward a dispensing nip of the drive system upon depletion of the primary roll; a housing; and an auxiliary access aperture fitted with an access door, the auxiliary aperture and access door being configured and adapted to be manually operable to expose the reserve roll for manual dispensing.
摘要:
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 generally planar polymeric creping belt provided with a plurality of perforations through the 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 that includes 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. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions of the dried web, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the hollow domed regions formed along at least the leading edge thereof.

A sheet product dispenser includes a transfer bar, a roller assembly, a motor, a sensor, and a controller. The transfer bar is movable between first and second positions. The roller assembly, disposed proximate the transfer bar second position, has a drive roller and a pinch roller that define a nip. The motor is in operable communication with the transfer bar to move the transfer bar between the first and second positions. The sensor is in operable communication with the dispenser cover. The controller is in operable communication with the sensor and the motor, and is responsive to executable instructions to facilitate actuation of the motor in response to a signal from the sensor to cause the transfer bar to move between the first position and second positions. The transfer bar includes at least one finger that drives an end of a roll of sheet product towards the nip upon actuation of the transfer bar from the first position to the second position.
摘要:
Described herein are methods and systems for minimizing folding defects when rolling a paper product. The method comprises rotating a roll in a manner that draws a paper product toward the roll. The location of a pick-up point between the roll and the paper product is altered by influencing the air pressure experienced by the paper product. This may be accomplished by flowing air in one of several manners described in the specification.
摘要:
An absorbent cellulosic sheet includes a papermaking-fiber reticulum. The papermaking-fiber reticulum includes a plurality of fiber-enriched regions that are oriented in a cross-machine direction (CD) of the sheet. The fiber-enriched regions have (i) a local basis weight and (ii) papermaking fibers that are oriented in the CD of the sheet. The papermaking-fiber reticulum also includes a plurality of linking regions that link corresponding ones of the fiber-enriched regions together in linking directions, the linking regions having (i) basis weights that are lower than those of the corresponding ones of the fiber-enriched regions and (ii) papermaking fibers that are oriented in the linking directions.
