The present disclosure relates to an absorbent tissue paper product comprising one ply being an essentially continuous ply of fibrous structure having a first side and a second side, the first side having a surface roughness arithmetical mean height (Sa1), and said second side having a surface roughness arithmetical mean height (Sa2). Said ply has a micro-embossed structure and a difference between the surface roughness arithmetical mean heights of the first side and the second side is 7 μm or less (|Sa1−Sa2|≤7 μm), and said ply having a bulk of at least 7.5 cm3/g. The disclosure also relates to a method and an apparatus for producing such an absorbent tissue paper product.

A multi-ply tissue paper product includes at least three plies. The tissue paper product includes a first inner ply being a creped ribbed ply and having a basis weight of 10 to 30 gsm, and a first outermost ply and a second outermost ply on each side of said inner ply, the first and second outermost plies being non-ribbed plies, wherein a creped ribbed ply is a ply including ribs and valleys providing an average core roughness Rk in the range 10 to 300 μm, and peaks being 4 to 12 per cm as measured along said first direction; and wherein a non-ribbed ply is a ply displaying no parallel ribs and valleys extending continuously along any direction of the ply or displaying parallel ribs and valleys extending continuously along any direction of the ply, the ribs and valleys providing peaks being less than 4 per cm.

A multi-layered product having an embossed interior layer is disclosed along with a method of making the product. The multi-layered product has a first layer with an interior surface, a second layer with an interior surface, and a third layer sandwiched between the first and second layers. The third layer has a first surface and a second surface and has a thickness therebetween. The third layer is embossed into a waffle pattern having a plurality of protrusions and a plurality of recesses. Each of the plurality of protrusions and recesses is adjacently aligned and horizontally offset from one another. The plurality of protrusions forms a horizontal plane, at the first surface, which is positioned above a horizontal plane formed by the plurality of recesses, at the first surface. The product also has an adhesive which secures the three layers together.

An application mechanism is used to apply water to wet paper in a process for producing planar cushioning material and filler material made of paper having a spatial structure with embossing on each side. The water can be applied to the paper like ink, so as to keep it sufficiently moist for the embossing process. Likewise, it is possible to use ink to apply a two-dimensional imprint, whereby sufficient wetting can also take place, but at the same time an optical effect is achieved.

A hygienic tissue paper includes first slits that are disposed in a longitudinal direction at predetermined intervals, the first slits extending in a width direction intersecting the longitudinal direction, wherein the first slits each include perforations, and wherein a cut length of each of the perforations increases from at least one end in the width direction toward a central portion in the width direction.

A multi-layered product having an embossed interior layer is disclosed along with a method of making the product. The multi-layered product has a first layer with an interior surface, a second layer with an interior surface, and a third layer sandwiched between the first and second layers. The third layer has a first surface and a second surface, and has a thickness there between. The third layer is embossed into a waffle pattern having a plurality of protrusions and a plurality of recesses. Each of the plurality of protrusions and recesses is adjacently aligned and horizontally offset from one another. The plurality of protrusions form a horizontal plane, at the first surface, which is positioned above a horizontal plane formed by the plurality of recesses, at the first surface. The product also has an adhesive which secures the three layers together.

A device for micro-embossing paper includes at least one micro-embossing unit to micro-emboss a wet paper ply. The micro-embossing unit includes a micro-embossing cylinder and a counter cylinder facing the micro-embossing cylinder at an embossing area where the wet paper ply is subjected to micro-embossing, and a heater to dry the wet paper ply. The micro-embossing cylinder includes a side surface partially wrapped by the wet paper ply. The heater heats at least one portion of the side surface partially wrapped by the wet paper ply to dry the wet paper ply.

Disclosed am multi-ply tissue products, particularly creped and through-air dried facial tissue products, having improved strength and softness. For example, the products have a geometric mean tensile strength (GMT) greater than about 1,2000 g/3″, a geometric mean tensile energy absorption (GM TEA) of about 20 g.Math.cm/cm.sup.2 or greater and a TS7 value less than about 16.0. In certain instances, the tissue products also have a low degree of stiffness and a relatively smooth surface, such as a Stiffness Index less than about 8.00 and a TS750 value less than about 15.0. The tissue products may be prepared from webs manufactured by a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web.

Disclosed are multi-ply tissue products, particularly wet pressed facial tissue products that have been recreped. For example, disclosed are tissue products prepared from wet pressed tissue webs that have been recreped using a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web. The tissue products have improved strength and softness, such as a geometric mean tensile strength (GMT) greater than about 1,400 g/3″, a geometric mean tensile energy absorption (GM TEA) of about 20 gocm/cm2 or greater and a TS7 value less than about 16.0. In certain instances, the tissue products also have a low degree of stiffness and a relatively smooth surface, such as a Stiffness Index less than about 8.00 and a TS750 value less than about 20.0.

Disclosed are multi-ply tissue products, particularly creped and through-air dried tissue products, having cloth like properties, such as good drapability and durability. For example, the products generally comprise two plies and have a geometric mean slope (GM Slope) less than about 10.0 kg and a geometric mean tensile energy absorption (GM TEA) of about 15 g.Math.cm/cm.sup.2 or greater. In certain instances, the tissue products also have a low degree of stiffness, such as a Stiffness Index less than about 5.00. The tissue products may be prepared from webs manufactured by a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web.
