The present invention related to the use of a surface-reacted natural calcium carbonate as filler in tissue paper products, to a process to prepare tissue paper products, and to a tissue paper product featuring an improved softness, wherein said surface-reacted natural calcium carbonate is the reaction product of a natural calcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and / or supplied externally.

An absorbent paper sheet for tissue or towel includes from about 99 percent to about 70 percent by weight of cellulosic papermaking fiber and from about 1 percent to about 30 percent by weight fibrillated regenerated cellulose microfiber which was regenerated form a cellulosic dope utilizing a tertiary amine N-oxide solvent or an ionic liquid. Fibrillation of the microfiber is controlled such that it has a reduced coarseness and a reduced freeness as compared with unfibrillated regenerated cellulose microfiber from which it is made and provides at least one of the following attributes to the absorbent sheet: (a) the absorbent sheet exhibits an elevated SAT value and an elevated wet tensile value as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (b) the absorbent sheet exhibits an elevated wet / dry CD tensile ratio as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (c) the absorbent sheet exhibits a lower GM Break Modulus than a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber; or (d) the absorbent sheet exhibits an elevated bulk as compared with a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber. In some embodiments, the pulp is pre-treated with debonder to enhance the wet / dry CD tensile ratio of the sheet.

A multilayer belt structure that can be used for creping or structuring a cellulosic web in a tissue making process. The multilayer belt structure allows for the formation of various shaped and sized openings in the top surface of the belt, while still providing a structure having the strength, durability, and flexibility required for tissue making processes.

A tissue paper product having at least one ply, wherein only one outer surface of said tissue paper product has a polyhydroxy compound applied thereto by slot extrusion, said polyhydroxy compound providing said tissue paper product with a Wet Burst greater than about 90 g, a Dynamic Coefficient of Friction less than about 0.9, and a Bending Flexibility less than about 0.1 gf cm2 / cm.

Fibrous sheets are coated or impregnated with a biodegradable composition to render the sheets more resistant to penetration by liquids. Biodegradable polymer blends suitable for use in coating or impregnating a fibrous sheet can be manufactured from at least one “hard” biodegradable polymer and at least one “soft” biodegradable polymer. “Hard” biopolymers typically have a glass transition temperature of at least about 10° C. “Soft” biodegradable polymers typically have a glass transition temperature less than about 0° C. Another useful biodegradable polymer composition includes one or more biodegradable polymers and sufficient inorganic filler so as to render the treated sheet microwaveable. The biodegradable polymer compositions are especially well-suited for coating or impregnating paper sheets, e.g., 12–15 lb / 3000 ft2 tissue paper to yield food wraps. Food wraps will typically be manufactured to have good “dead-fold” properties so as to remain in a wrapped position and not spring back to an “unwrapped” form.

A method of producing a tissue paper web in a papermaking machine including the steps of forming the web on a skin, selecting a quality of the web, bypassing a dewatering apparatus, passing the skin and web through a nip and conveying the web to a drying cylinder from the skin. The web is formed in a forming section of the machine from a pulp suspension on the skin. In the selecting step a quality of the web is selected thereby defining a quality selection of absorbency or tear resistance. The bypassing step includes bypassing the dewatering apparatus with the web and selecting a type of the skin dependent upon the quality selection. The machine being configured to bypass the dewatering apparatus dependent upon the quality selection; when the quality selection is tear resistance then the skin is a non-structured skin or a felt and the dewatering apparatus is bypassed, when the quality selection is the absorbency then the skin is a three-dimensionally structured skin or a structured mesh and the dewatering apparatus is not bypassed. In the passing step the skin and the tissue paper web passes through a nip defined between a cylindrical surface of the drying cylinder and a mating surface of a press roller.

A dispensing unit includes an outer front wall, two outer side walls, a housing for holding a pile of a continuous length of accordion-like folded web of towels of tissue paper or nonwoven including bundles, the outer front wall having an access opening to the pile, a dispensing opening for the web of towels and a feeding mechanism including a member for controlling the dispensing of the web of towels, a drive unit and a braking arrangement for the web of towels. A unit of consumable articles includes the pile of bundles with connecting elements therebetween, which are inserted through the access opening into the housing in the dispensing unit and added to the bottom of the pile. The web of towels is dispensed from the upper part of the pile by a feeding mechanism, which positions the web of towels in a starting mode in the dispensing opening.

Single-ply absorbent tissue paper wherein of the fibers incorporated in the web: (a) at least 20% by weight have a coarseness exceeding 23 mg / 100 m; (b) at least about 20% by weight have a coarseness of less than about 12 mg / 100 m; and (c) the weight average fiber coarseness to length ratio is less than about 8.5 mg / 100 m / mm. The single-ply tissue having: a serpentine configuration; low sidedness; a basis weight of at least about 12.5 lbs. per 3000 square foot ream; specific total tensile strength between 40 and 200 g / 3 inches / lb per 3000 square foot ream; a cross direction specific wet tensile strength between 2.75 and 20.0 g / 3 inches / lb per 3000 square foot ream; an MD tensile to CD tensile ratio between 1.25 and 2.75; a specific geometric mean tensile stiffness between 0.5 and 3.2 g / inch / % strain per pound per 3000 square foot ream; a friction deviation less than 0.250; and a sidedness parameter less than 0.30.

The invention relates to an absorbent paper product, made in particular of tissue paper, that includes at least two plies, at least one of which is embossed according to an embossing pattern that includes projections (1, 2, 3) with a density of 30 or more per cm2. According to the invention, the embossing patterns include at least two adjacent zones whose projections (1, 2, 3) have, respectively, a different density and / or a different surface area at the peak so as to produce a relief effect on the product.
