Abstract: The present invention is a method and composition for preventing the deposition of contaminants from resinous pulp and/or recycled pulp in the press section of a pulp and paper process. The composition of the invention includes a cleaning solvent comprising a blend of aromatic hydrocarbons containing between nine and eleven carbon atoms and a surfactant comprising an alcohol ethoxylate. The composition of the invention can be applied to the felts in the press felt section of a pulp and paper process to break down and loosen deposited contaminants and the contaminants can be removed thereby preventing the need for batch cleaning and downtime in the press felt section.

Abstract: An improved method for inhibiting the deposition of adhesive contaminants, hot melts and/or pressure sensitive adhesive materials onto the surfaces of secondary paper products and repulping equipment during the manufacture of same from waste paper products comprises the application of a water-soluble dispersant selected from the group consisting of a hydrophobically modified hydrocolloid or an acrylic acid polymer. The dispersant, preferably a modified guar gum or sodium acrylic acid/maleic acid copolymer improves product quality and papermaking equipment performance.

Abstract: Disclosed is a process for washing or otherwise treating paper pulp. More specifically, a multi-stage paper pulp washing process including the use of a defoamer/emulsifier mixture which is adjusted at a paper manufacturing site for each stage. The same defoamer may be used in each washing stage. However, solubility is adjusted at the paper manufacturing site by adding a small amount of emulsifier to the defoamer as appropriate for the particular stage.

Abstract: The invention relates to a method for enhancing the anti-skid or friction properties of a cellulosic fiber, by transporting cellulosic fiber from a machine chest and then to a stuff box and then to a headbox; and contacting a suspension of the cellulosic fiber with an anionic colloidal silica prior to or at the stuff box. The invention further relates to a method for enhancing the anti-skid or friction properties of a cellulosic fiber, by transporting cellulosic fiber from a stuff box to a headbox; and contacting a suspension of the cellulosic fiber with an anionic colloidal silica prior to or at the stuff box. The invention further relates to the products produced by the present invention.

Abstract: The invention relates to a composition for enhancing the strength or sizing properties of a cellulosic fiber, comprising a) a self-emulsifying isocyanate and b) a coupling agent. The invention also relates to a kit of the composition, a process for enhancing the strength or sizing of a cellulosic fiber, products made from the process, and modified cellulosic fiber.

Abstract: An aqueous slurry of smectite clay of elevated solids content, comprising an aqueous solution or emulsion of at least 0.2% by weight of said slurry of a salt of a low molecular weight amine salt, in which is dispersed from about 10 to 47% by weight of the slurry, of a smectite clay. The amine salt is effective to prevent the smectite from swelling appreciably, whereby the slurry can be shipped and stored without creating a gelling problem. The inhibiting or suppressing effect of the amine salt on the swelling of the clay and on gelling of the slurry is reversible upon subsequent dilution with water, thereby facilitating use of the smectite in typical applications, e.g. as a retention aid in paper making, or as a viscosifier.

Abstract: An improved composition is provided for increasing the coefficient of friction of surfaces to which it is applied. The composition consists of an aqueous suspension of an ether and at least one material selected from the group comprising colloidal silica, colloidal silica and alumina, or colloidal silica and metal oxides, wherein the ratio of the material to the ether is from 1:1 to 25:1.

Abstract: A formaldehyde reduction composition which comprises from about 0.1% to about 0.6% by weight of a water soluble lignosulfonate salt, from about 22% to about 28% by weight of a di- or tri- alkylene amine, from 0% to about 28% by weight of di- or tri- alkanol amine, and from about 43.4 about 77.9% water. The composition is particularly useful in the treatment of aqueous media, especially calcium carbonate and kaolin mineral slurries which have been treated with a formaldehyde-releasing biocide.

Abstract: Pulp bleaching processes employing peroxides and/or oxygen are improved by using bleaching additives, preferably before the application of the peroxide and/or oxygen. The bleaching additives contain at least one alkali metal sulfamate such as a sodium sulfamate and a polyaminocarboxylic acid such as DTPA or a salt thereof, such as sodium DTPA.

Abstract: Pulp bleaching processes employing peroxides and/or oxygen are improved by using stabilizing bleaching additives, preferably before the application of the peroxide and/or oxygen. The bleaching additives contain at least one sulfamic acid or sulfamate such as sodium sulfamate and gluconic acid or a soluble gluconate, or alternatively an alkali metal borate.

Abstract: A wringer mop including a handle and a head portion having a plurality of mop strands, and an improved connector for connecting the mop strands to the handle. The connector includes a connector body having a collar portion and a hollow shank portion. A strand clip is provided for engaging with the mop strands and includes a pair of legs for extending into engagement with the shank portion whereby the strand clip is attached to the connector body. The mop is assembled by first engaging the mop strands with the strand clip and then connecting the strand clip to the connector body. Subsequently, the assembled connector body and strand clip may be attached to the bottom of the handle by inserting the shank portion into the handle.

Abstract: A wound broom including an elongated tubular handle formed of metal and a plastic cover extending over an exterior surface of the handle. A plurality of elongated ribs are provided extending along the length of the handle, the ribs being defined by alternating lands and grooves. The lands include sharp edges and are spaced from each other a predetermined distance to provide a desired tactile feel for the handle and to facilitate gripping of the handle in a winding operation for the broom. In addition, a plastic plug and insert is provided in an end of the handle. The plug is provided with an aperture for receiving the leading end of a winding wire for facilitating initiation of a winding operation.

Abstract: A merchandising and shipping box for implements, such as mops and brooms. The box may be used for shipping the implements as well as for supporting the implements on display. The box includes opposing side panels, front and rear panels, a bottom panel and a top panel. The top panel is provided with a plurality of apertures arranged in two spaced rows, and an elongated slot extending between the two rows of apertures. The apertures are adapted to support handle portions of the implement with head portions thereof oriented upwardly, and the elongated slot is connected to an enlarged transverse slot for receiving head portions of the implements therethrough whereby the implements may be positioned within the elongated slot with the head portion oriented downwardly. The different orientations of the implements within the box facilitates viewing of the implements as well as provides a stable support for the implements while on display.

Abstract: A mop package for use with a mop including a mop head and a handle pivotally connected to the mop head. The package includes a body portion for receiving the mop head and a biasing portion connected to the body portion. The biasing portion includes an aperture for receiving the handle of the mop and is formed with a triangular configuration which facilitates biasing the mop head to an orientation where it is substantially parallel to the handle of the mop.

Abstract: A sponge mop head including a support plate for supporting a sponge and a wringer plate pivotally attached to a front edge of the support plate. A planar extension plate portion is provided extending rearwardly from the support plate such that a sponge will be substantially fully compressed between the wringer plate and the support plate and extension plate portion during a wringing operation. In addition, a handle mounting socket is provided located rearwardly of the support plate for facilitating use of the mop in low overhang areas, and to accommodate a wringer plate large enough to fully cover a compressed sponge during a wringing operation.
