Various embodiments of the present invention relate to surface enhanced pulp fibers, various products incorporating surface enhanced pulp fibers, and methods and systems for producing surface enhanced pulp fibers. Various embodiments of surface enhanced pulp fibers have significantly increased surface areas compared to conventional refined fibers while advantageously minimizing reductions in length following refinement. The surface enhanced pulp fibers can be incorporated into a number of products that might benefit from such properties including, for example, paper products, paperboard products, fiber cement boards, fiber reinforced plastics, fluff pulps, hydrogels, cellulose acetate products, and carboxymethyl cellulose products. In some embodiments, a plurality of surface enhanced pulp fibers have a length weighted average fiber length of at least about 0.3 millimeters and an average hydrodynamic specific surface area of at least about 10 square meters per gram, wherein the number of surface enhanced pulp fibers is at least 12,000 fibers/milligram on an oven-dry basis.

A structured rolled sanitary tissue product having at least two plies, wherein the structured rolled sanitary tissue product has a crumple resistance of less than 30 grams force, a caliper of at least 450 microns/ply, and a bulk softness (TS7) of 10 or less.

There is provided a use of a pulp mixture for forming a container in a mould, which pulp mixture comprises: 65-90%, such as 70-84%, by dry weight of a first pulp having a Schopper-Riegler (SR) number of below 48, preferably below 40, more preferably below 30; and 10-35%, such as 16-30%, by dry weight of a second pulp having a Schopper-Riegler (SR) number of 60-90, preferably 70-90, more preferably 77-90. A pulp mixture and a method of producing a pulp mixture are also provided.

A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, the structuring fabric including knuckles formed on warp yarns of the structuring fabric, with the knuckles being positioned along lines that are angled relative to the machine direction of the fabric. The angle of lines relative to the machine direction is between about 10 and about 30. The method also includes drying the web to form the absorbent cellulosic sheet.

A structured tissue product produced using a structured or imprinting fabric and a press roll. The tissue product has at least two plies, and has a crumple resistance of less than 30 grams force and an average peak to valley depth of at least 65 microns.

The present invention provides a lyocell fiber with increased tendency to fibrillate, requiring a time of less than 80 minutes to obtain a 50 SR value according to ISO 5267-1: 1999 while the reduction of the working capacity [c N/tex*] at the 50 SR value is less than 50%, as well as a method for producing same and products comprising same.

A fabricating method of a pulp molded container includes providing a main material, performing a dispersing step, performing a pulping step, performing an additive adding step, and performing a heat compression molding step. The main material includes a long fiber pulp and a short fiber pulp. In the dispersing step, the main material is dispersed evenly in water to form an aqueous pulp solution. In the pulping step, the aqueous pulp solution is mechanically fibrillated to form a fibrillated pulp. In the additive adding step, an additive is added into the fibrillated pulp and mixed to form a paper pulp. In the heat compression molding step, the paper pulp is formed into the pulp molded container by heat compression molding.
