Abstract:
A method of making a dispersible wet wipe includes providing a web of cellulosic fibers. In one embodiment, a first binder is applied to a web surface in a coating that comprises randomly distributed deposits of the first binder. A second binder is applied an intermittent pattern on the web surface to define first regions on the first surface that include first binder but no second binder and to define second regions on the first surface that include both first binder and second binder. In a second embodiment, a first binder is applied to a web surface in a first pattern, and, after applying the first binder, a second binder is applied to the web surface in a second pattern that is different than the first pattern. In a third embodiment, a binder is applied to a web surface in a pattern, the pattern having first regions and second regions, wherein the add-on level of the binder in the first regions is lower than the add-on level of the binder in the second regions.
Abstract:
Die Erfindung betrifft ein Dünndruckpapier, das Zellstofffasern und mindestens einen säurelöslichen Füllstoff enthält, wobei der Gehalt an säurelöslichem Füllstoff mindestens 10 Gew.-% bezogen auf die gesamte Masse des Dünndruckpapiers beträgt, wobei das Dünndruckpapier Teilbereiche mit einer geringeren Transparenz und Teilbereiche mit einer höheren Transparenz aufweist, wobei der auf die Fläche bezogene Masseanteil des genannten säurelöslichen Füllstoffes in den Teilbereichen höherer Transparenz um mindestens 10% geringer ist als in den Bereichen geringerer Transparenz, und wobei für die Transparenz in den Teilbereichen höherer Transparenz mindestens eines der folgenden Kriterien erfüllt ist: - die nach DIN 53147: 1993-01 gemessene Transparenz in den Teilbereichen höherer Transparenz ist um mindestens 20% höher als die nach DIN 53147:1993-01 gemessene Transparenz in den Teilbereichen geringerer Transparenz, oder - die Transparenz ist in den Teilbereichen höherer Transparenz so viel höher als in den Teilbereichen geringerer Transparenz, dass sich auf einem einzelnen Blatt im Durchlicht bei künstlicher Beleuchtung mit einer Beleuchtungsstärke von 100 Lux bis 1000 Lux oder bei nicht nennenswert künstlich abgeschwächtem Tageslicht ein mit bloßem Auge wahrnehmbares Muster aus helleren und dunkleren Abschnitten erhalten lässt, wobei die helleren Abschnitte den Teilbereichen höherer Transparenz und die dunkleren Abschnitte den Teilbereichen geringerer Transparenz entsprechen.
Abstract:
In various embodiments, a conductive paper may be provided. The conductive paper may include a first layer including an electrically conductive nanostructured material. The conductive paper may also include a second layer over the first layer, the second layer including a cellulose material. The conductive paper may further include an intermediate layer between the first layer and the second layer, the intermediate layer including the electrically conductive nanostructured material interspersed between the cellulose material.
Abstract:
A surface coating for paper, the paper produced and method for producing the coated paper as described. The paper is made from at least one of a mechanically, or chemically-derived pulp and the coating includes aluminum sulfate to coagulate the inkjet ink at the paper surface and achieve improved print quality, when compared with coatings without aluminum sulfate.
Abstract:
An inkjet printable media comprises a paper base containing a surface coating comprising calcium chloride and a synergistic amount of a sulfate salt. When the printable media is printed with an inkjet ink containing a black pigment, a KOD value of the printed media is equal to or greater than that of a comparative inkjet printed media comprising up to 12 kg calcium chloride/T media and lacking the sulfate salt.
Abstract:
A method is provided for producing a wide range of high quality coated recyclable paper or paperboard for use in a variety of applications. In accordance with the process, paper or paperboard is coated with a polymer emulsion in one or more coating stations which are off-line from a paper or paperboard machine. The process provides coated paper or paperboard products with enhanced barrier properties.
Abstract:
Waxes prepared from hydrogenated plant oils, such as castor, palm, and soybean, are used to prepare water based emulsions. The inventive waxes, obtained from naturally derived, renewable resources, were emulsified under anionic, cationic and nonionic conditions, producing emulsions having a solids content up to about 45% solids. The emulsions are stable, and are characterized by having an average particle size less than 1000 nanometers. When used to coat fibrous cellulosic articles, such as paperboard, the emulsions' performance was similar to emulsions containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 49-94 degrees C (120-200 degrees F) (Mettler Drop Point). The inventive waxes are used as an alternative to petroleum-derived, or expensive naturally-occurring waxes in the manufacture of emulsions used in coatings, polishes, adhesives, paper products, paperboard and other manufacturing operations.
Abstract:
The invention relates to a method for finishing paper and paper products by treating the surface of the paper or paper products with at least one finishing means, at least one finishing means in the form of a pattern being applied on the upper side and/or lower side of the paper or paper products. The invention also relates to the paper and paper products obtained by said method.
Abstract:
In one embodiment, the present invention provides a method of forming a cellulose article having a specific volume of less than 3 cc/gm. The method includes the step of incorporating cellulose fibers with a compound, wherein the compound includes an aqueous dispersion. The aqueous dispersion may have at least one polymer selected from the group consisting of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof; at least one polymeric stabilizing agent; and water. In certain embodiments, a combined amount of the at least one polymer and the at least one stabilizing agent comprises about 25 to about 74 volume percent of the aqueous dispersion.
