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.
Fibrous Structures
Fibrous structures, and more particularly sanitary tissue products containing fibrous structures having a surface exhibiting a three-dimensional (3D) pattern such that the fibrous structure and/or sanitary tissue product exhibits novel properties compared to known fibrous structures and/or sanitary tissue products, and methods for making same are provided.

HIGHLY ABSORBENT ARTICLES
Absorbent wet laid products are made containing cellulose fibers and cellulose ester staple fibers that are co-refined to obtain products and articles that have improved water absorbency and tensile strength or burst strength or both. The absorbent wet laid products can now be made with a synthetic fiber in the wet laid operation since cellulose ester can be subjected to a refining operation.
Soft tissue comprising non-wood fibers

SOFT SANITARY TISSUE PAPER WEB PRODUCTS COMPRISING NANO-FILAMENTS
A soft sanitary tissue paper web comprising at least one ply is disclosed. The soft sanitary tissue paper web comprises from about 2% to about 56.5% by weight of the soft sanitary tissue paper web of a softwood pulp fiber mixture and from about 43.5% to about 99.9% by weight of the dry fiber basis of the soft sanitary tissue paper web of a hardwood pulp fiber mixture. The softwood pulp fiber mixture comprises from about 0% to about 56.4% by weight of the dry fiber basis of the soft sanitary tissue paper web of softwood pulp fiber; from about 0.05% to about 20.0% by weight of the dry fiber basis of the soft sanitary tissue paper web of cellulose nanofilaments; and, from about 0.05% to about 3.0% by weight of the dry fiber basis of the soft sanitary tissue paper web of strengthening additive.
ABSORBENT TOWEL PAPER WEB PRODUCTS COMPRISING NANO-FILAMENTS
An absorbent towel paper web comprising at least one ply is disclosed. The absorbent towel paper web has from about 45% to about 90% by weight of the dry fiber basis of the absorbent towel paper web of a softwood pulp fiber mixture and from about 10% to about 55% by weight of the dry fiber basis of the absorbent towel paper web of a hardwood pulp fiber mixture. The softwood pulp fiber mixture has from about 20% to about 89.9% by weight of the dry fiber basis of the absorbent towel paper web of softwood pulp fibers; from about 0.05% to about 20% by weight of the dry fiber basis of the absorbent towel paper web of cellulose nanofilaments; and, from about 0.05% to about 5.0% by weight of the dry fiber basis of the absorbent towel paper web of strengthening additive.
Fibrous structures
Fibrous structures, and more particularly sanitary tissue products containing fibrous structures having a surface exhibiting a three-dimensional (3D) pattern such that the fibrous structure and/or sanitary tissue product exhibits novel properties compared to known fibrous structures and/or sanitary tissue products, and methods for making same are provided.
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.
Hygienic thin-leaf paper
A hygienic thin-leaf paper including a first sheet having front and back surfaces, on which embossed protrusions and embossed recesses corresponding to the embossed protrusions are respectively formed; and a second sheet having front and back surfaces, on which embossed protrusions and embossed recesses corresponding to the embossed protrusions are espectively formed, wherein the first sheet and the second sheet are integrated by facing the surfaces formed with the embossed protrusions in a nested form, wherein each of the first sheet and the second sheet have an embossed portion, on which the embossed protrusions and non-embossed-protrusion portions are formed, wherein at least one of the first sheet and the second sheets have a non-embossed portion, on which the embossed protrusions and the non-embossed portions are not formed, and wherein the non-embossed portion is in a shape without having an intersection.
