TISSUE PAPER MATERIAL AND TISSUE PAPER PRODUCT

The present disclosure relates to a single-ply tissue paper material having a basis weight less than 40 gsm and a GMT tensile strength of at least 60 N/m. comprising a non-wood tissue ply. comprising non-wood cellulose pulp fibres being present in an amount of at least 10% by dry weight of the of the non-wood tissue ply. The disclosure also relates to a single-ply tissue paper product and to a multi-ply tissue paper product comprising at least one non-wood tissue ply.

Pre-moistened wet wipe products in perforated roll form made of tissue based substrates

The present invention is directed to wet wipes and methods of making thereof. In one aspect, a wet wipe includes a multi-ply tissue impregnated with a wetting composition. The multi-ply tissue includes papermaking fibers, is substantially free of synthetic fibers, and has an absorbent capacity of at least about 8 grams of the wetting composition per gram of the dry multi-ply tissue (g/g) as measured in accordance with American Society for Testing and Materials International (ASTM International) standard D4250. A single ply of the multi-ply tissue has a basis weight of at least 8 pounds per 3,000 square foot ream (lb/rm).

Fibrous Structures and Methods for Making Same

Fibrous structures that exhibit a novel combination of properties and to methods for making such fibrous structures are provided.

Grafted crosslinked cellulose used in absorbent articles

Grafted, crosslinked cellulosic materials used in absorbent articles, the grafted crosslinked cellulosic materials including cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted thereto, in which one or more of the cellulose fibers and the polymer chains are crosslinked (such as by intra-fiber chain-to-chain crosslinks). Some of such materials are characterized by a wet bulk of about 10.0-17.0 cm.sup.3/g, an IPRP value of about 1000 to 7700 cm.sup.2/MPa.Math.sec, and/or a MAP of about 7.0 to 38 cm H.sub.2O. Methods for producing such materials may include grafting polymer chains from a cellulosic substrate, followed by treating the grafted material with a crosslinking agent adapted to effect crosslinking of one or more of the cellulosic substrate or the polymer chains.

LOW COARSENESS SOUTHERN SOFTWOOD PULPS

Pulp sheets produced from Southern pine fibers are disclosed. Embodiments in which the fibers have a fiber length to coarseness ratio equal to or greater than 0.11, with fiber length (LWAFL) in mm and coarseness in mg/100 m, are found to impart stiffness properties to tissue grade handsheets made therefrom comparable to those achieved using of standard NBSK. Embodiments in which the fibers have a low coarseness (of from about 16 to about 20 mg/100 m, at a fiber length (LWAFL) of from about 1.6 to about 3.0 mm) are found to impart wicking properties to absorbent structures made therefrom that are improved relative to those achieved using standard high coarseness SBSK.

Creped Fibrous Structures

Creped fibrous structures having pillows and knuckles, wherein the creped fibrous structures exhibit improved knuckle properties, such as Knuckle Roughness Ra, Knuckle Roughness Rq, and Knuckle Creping Frequency and methods for making same are provided.

SOFT TISSUE COMPRISING NON-WOOD FIBERS

The present invention provides soft, durable and bulky tissue products comprising non-wood fibers and more particularly hesperaloe fiber. The inventors have discovered that high yield hesperaloe pulp fiber, when incorporated in amounts of at least about 5 percent by weight of the tissue product, produces products having a GMT less than about 1000 g/3 and a GM Slope less than about 7.0 kg. At the foregoing tensile strengths and modulus the tissue products of the present invention are also generally soft, such as having a Stiffness Index less than about 10.0, and more preferably less than about 9.0, such as from about 7.0 to about 9.0.

HIGHLY DURABLE TOWEL COMPRISING NON-WOOD FIBERS

The present invention relates to tissue products comprising high yield hesperaloe fiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yield hesperaloe pulp fibers surprisingly improves the CD Wet/Dry ratio without negatively affecting the absorbency of the tissue product. For example, tissue products of the present invention generally have an Absorbent Capacity greater than about 6.0 g/g, such as from about 6.0 to 8.0 g/g. As such the tissue products are durable when wet, but are still sufficiently absorbent. This balance of absorbency and wet strength is not found in the prior art without resorting to adding latex binders or the like to the tissue product.

Fibrous structures and methods for making same

Fibrous structures that exhibit a novel combination of properties and to methods for making such fibrous structures are provided.

Through-air drying apparatus and methods of manufacture

Unlike conventional through-air drying processes the instant invention utilizes at least two through-air driers where the first dyer is at least partially encircled by a first through-air drying fabric and the second dyer is at least partially encircled by a second through-air drying fabric. By providing each through-air dryer with its own fabric the overall drying performance may be increased. Additionally, in certain embodiments, the first and second fabrics may be different to optimize both the drying performance and/or tissue product properties.
