    摘要： 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.

    摘要： The disclosure provides a dispersion for making décor paper having improved optical performance without negatively impacting mechanical strength comprising a TiO2 particle slurry comprising a treated TiO2 particle having a surface area of at least about 30 m2/g, and a cationic polymer; wherein the treatment comprises an oxide of silicon, aluminum, phosphorus or mixtures thereof; and the treatment is present in the amount of at least 15% based on the total weight of the treated titanium dioxide particle; paper pulp; and a cationic polymer; wherein the cationic 1.5 polymer in the slurry and the cationic polymer in the dispersion are compatible; wherein for equal optical performance, the amount of treated TiO2 particle in the dispersion is reduced by about 10% when compared to a dispersion not comprising the treated TiO2 particle of (a). These dispersions are useful in making décor paper that may be used in paper laminates.
