A binder includes an inorganic oxide particle and a binding material particle containing a binding material to mutually bind fibers when water is provided, wherein the binder includes a composite particle in which the binding material particle and the inorganic oxide particle are integrated, the inorganic oxide particle contains carbon, and the content of the carbon is 2% by mass or more relative to the mass of the inorganic oxide particle.

A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.

A paper forming mold, comprising a roller (1). A number of through micropores are formed on a wall of the roller (1), and one or more patterns and characters of a normal watermark, a white watermark, a windowed security thread, and a paper marker are carved on the wall of the roller (1). The paper forming mold has a high reproducibility for an original watermark design draft, improves consistency, clarity, three-dimensionality, detail refinement and richness of the watermark in paper, and thus enhances the anti-counterfeiting function of the watermarked paper; the service life of the paper forming mold is prolonged; and the automation level of paper forming mold manufacturing is improved, and the labor intensity is greatly reduced.

A process for fibrillating a fibrous pulp, and products made using the same. The process comprises providing a fibrous pulp of liquid and staple fibers having a first liquid to fibers ratio of less than or equal to 6:1, applying stress to the pulp to fibrillate the staple fibers; and, during said applying stress, drying the pulp to a second liquid to staple fibers ratio of less than or equal to 0.43:1.

A method for recycling paper to produce a less white and clean office paper product for paper printing and writing, said method comprising the steps of: collecting waste papers; sorting said collected papers waste without the need to separate between the various paper grades; pressing said sorted recycled paper; pulping said sorted recycled paper by a pulper which contains water turns into a mixture; said pulper chops said sorted recycled paper into small pieces; heating said pulp mixture breaks said recycled paper down more quickly into tiny strands of cellulose or fibers to eventually, said sorted recycled paper turns into a pulp; sieving, said pulp is forced through sieves containing holes and slots of various shapes and sizes, said sieves remove small contaminants; cleaning, said pulp spinning around in large cone-shaped cylinders; heavy contaminants are thrown to the outside of the cone and fall through the bottom of the cylinder; lighter contaminants collect in the center of the cone and are removed; refining, said pulp is beaten to make said recycled fibers swell for papermaking; if said pulp contains any large bundles of fibers, said refining step separates said bundles into individual fibers; dewatering, said watery pulp enters a headbox at a paper machine, and then is sprayed in a continuous wide jet onto a huge flat wire sieve which is moving very quickly through said paper machine; on a sieve, water starts to drain from said pulp, and said recycled fibers quickly begin to bond together to form a watery sheet; said sheet moves rapidly through a series of felt-covered press rollers which squeeze out more water; said sheet, which now resembles paper, passes through a series of heated metal rollers which dry said paper’, said dried paper is wound into a giant roll and removed from the paper machine; the roll of said paper is cut into smaller rolls, or sometimes into sheets and made into said paper product.

Provided is a palp fibrous accumulated sheet including: a liquid permeable pulp fibrous accumulated layer containing a crushed pulp or base-fibers mainly including a crushed pulp, and a binder; and a plurality of fiber crimped parts formed by compression and pressurization, the fiber crimped parts being formed so that crushed pulp fibers each straddling the adjacent fiber crimped parts are present.

A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, and more particularly to multi-ply articles containing two or more fibrous structure plies having a plurality of fibrous elements wherein the articles exhibit improved bulk and absorbent properties compared to known articles and methods for making same, are provided.

Products having improved emboss definition, emboss visibility, and perceived softness are described. The tissue products comprise an emboss pattern including multi-apex, high aspect ratio embossing elements that do not suffer from the prior art issues of bunching, puckering and folding. When included in a multi-ply product, the embossed tissue also possesses less adhesive than prior art patterns resulting in a product with improved softness and drape.
