The present invention provides mufti-layered tissue webs, and tissue product comprising the same, comprising long, high-coarseness wood pulp fibers selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing long, high-coarseness wood pulp fibers in one or more outer layers, even in relatively modest amounts, may improve certain product properties, such as durability, without negatively affecting softness. In certain instances, both the softness and durability may be improved by selectively incorporating long, high-coarseness wood pulp fibers in one or more of the outer layers.

A differential density paper product comprising at least one paper web is disclosed. The paper product has: (a) from about 20% to about 90% by weight of the dry fiber basis of the paper product of a refined soft wood pulp fiber mixture, (b) pulp fibers selected from the group consisting of hard wood fibers, non-wood fibers, recycled fibers, synthetic polymer fibers, bleached eucalyptus kraft fibers, and combinations thereof; and, (c) not more than about 10% by weight moisture.

The present invention provides a through-air dried tissue product comprising regenerated cellulose fibers that can provide 25 percent or less of the total weight of the through-air dried tissue product. The regenerated cellulose fibers can have a linear density less than about 1.5 dtex and a fiber length of less than 6.0 mm. The through-air dried tissue product can provide improvements in softness at a given strength.

Paper products such as tissues can be made using a furnish comprising surface enhanced pulp fibers (“SEPF”). In some embodiments, SEPF have a weighted average fiber length of at least 0.3 millimeters (mm) and an average hydrodynamic specific surface area of at least 10 square meters per gram (m.sup.2/g). In some embodiments, a furnish or a paper product can comprise at least 2% SEPF by dry weight. In some embodiments, a paper product comprising SEPF can be formed from a furnish having a freeness of 650 ml Canadian Standard Freeness (CSF) or less, optionally 600 ml CSF or less.

A process and an apparatus for producing nonwoven materials are disclosed. The process includes the following steps: a) providing a three-phase (gas-liquid-solid) suspension containing air, water, fibrous material and a surfactant, b) depositing the suspension onto a moving carrier sieve to produce a fibrous web on the carrier sieve, c) removing aqueous residue of the suspension through the carrier sieve, d) conveying the aqueous residue through one or more phase separation tanks in an essentially horizontal direction while providing a depressurised headspace above the aqueous residue, e) recycling the aqueous residue conveyed in step d) to step a), f) preferably pre-integrating the fibrous web.

A differential density absorbent towel paper product comprising at least one absorbent towel paper web is disclosed. The absorbent towel paper web has: (a) from about 20% to about 90% by weight of the dry fiber basis of the absorbent towel paper web of a refined soft wood pulp fiber mixture, (b) pulp fibers selected from the group consisting of hard wood fibers, non-wood fibers, recycled fibers, synthetic polymer fibers, bleached eucalyptus kraft fibers, and combinations thereof and, (c) not more than about 10% by weight moisture. The refined soft wood pulp fiber mixture has: i) from about 18.5% to about 88.5% by weight of soft wood pulp fiber; ii) from about 0.25% to about 5.0% by of cationic strengthening polymer; and, iii) from about 0.05% to about 20% by weight of cellulose nano-filaments.
