Multi-ply fibrous structure-containing articles

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, wherein at least one of the fibrous structure plies is embossed and is bonded to at least one other fibrous structure ply by a water-resistant bond such that void volume is created between the bonded fibrous structure plies.

Seamless unitary deflection member for making fibrous structures having increased surface area and process for making same

A seamless unitary deflection member. The seamless unitary deflection member can have a backside defining an X-Y plane and a thickness in a Z-direction. The seamless unitary deflection member may also have a reinforcing member and a plurality of protuberances positioned on the reinforcing member. Each protuberance may have a three-dimensional shape such that any cross-sectional area of the protuberance parallel to the X-Y plane can have an equal or lesser area than any cross-sectional area of the protuberance being a greater distance from the X-Y plane in the Z-direction.

Sanitary tissue product with a shaped line of weakness

A web of toilet tissue that includes a shaped line of weakness, wherein the toilet tissue exhibits a LWP Factor of greater than about 7, and a Geometric Mean Peak Elongation of greater than about 15%, as measured according to the Dry Tensile Strength Test Method.

TISSUE PRODUCT AND METHOD AND APPARATUS FOR PRODUCING SAME

A tissue product with at least four plies made of tissue paper base sheet or nonwoven comprises: a first outer ply and a second outer ply and at least two inner plies between the first outer ply and the second outer ply, wherein only one of the inner plies is un-embossed; the outer plies comprise a micro-embossing pattern; at least one of the outer plies comprises a décor embossing pattern; and at least two adjacent inner plies comprise the un-embossed inner ply and one micro-embossed inner ply; wherein the density of the micro-embossed protrusions of the micro-embossed inner ply is different to the density of further embossed protrusions of the micro-embossing pattern of the outer ply which is adjacent to the micro-embossed inner ply.

WOVEN PAPERMAKING FABRIC HAVING DISCRETE CROSS-MACHINE DRIECTION PROTUBERANCES
20220010491 · 2022-01-13 ·

Disclosed are woven papermaking fabrics having a machine direction (MD) axis and a cross-machine direction (CD) axis, a machine contacting surface and a web contacting surface. The web contacting surface comprises a plurality of MD and CD oriented protuberances. Generally the MD oriented protuberances are formed from warp filaments and may be continuous across one dimension of the papermaking fabric. The CD oriented protuberances are formed from shute filaments and are discrete. The fabrics may be woven such that the CD oriented protuberances traverse at least one MD oriented protuberance and in other instances two or more MD oriented protuberances. In addition to MD and CD oriented protuberances, the web contacting surface comprises valleys disposed between adjacent MD oriented protuberances. The valleys are generally permeable to air and water and aid in the formation and structuring of webs manufactured using the fabrics.

WOVEN PAPERMAKING FABRIC HAVING INTERSECTING TWILL PATTERNS
20220010490 · 2022-01-13 ·

Disclosed are woven papermaking fabrics useful in the manufacture of fibrous structures, particularly wet-laid tissue products that allow the web contacting surface of the fabric to be woven with three-dimensional topography comprising protuberances that are oriented at an angle relative to both the machine direction (MD) axis and cross-machine (CD) axis of the fabric. The protuberances may be discrete or continuous and, in certain referred embodiments, intersect one another to form discrete valleys there between. The valleys may have relatively steep sidewalls, such as wall angles greater than 22 degrees, and be relatively deep, such as valley depths greater than about 0.35 mm.

Tissue paper converting line and method

A converting line for processing tissue paper includes an unwinder for unwinding reels of tissue paper; a rewinding machine for forming rolls of tissue paper; a feeding path between the unwinder and the rewinding machine, for at least one ply of tissue paper; along the feeding path, a first detection unit to detect the thickness of the tissue paper fed along the feeding path in a feeding direction; a control system, interfacing with the detection unit, and configured to act on at least one production parameter of the converting line based on the detected tissue paper thickness.
