摘要： Throughdried tissue products such as facial tissue, bath tissue, and paper towels are made using a throughdrying fabric having from about 5 to about 300 machine direction impression knuckles per square inch (per 6.45 square centimeters) which are raised above the plane of the fabric. These impression knuckles create corresponding protrusions in the throughdried sheet which impart a significant amount of cross-machine direction stretch to the sheet. In addition, other properties such as bulk, absorbent capacity, absorbent rate and flexibility are also improved.

摘要： Throughdried tissue products such as facial tissue, bath tissue, and paper towels are made using a throughdrying fabric having from about 5 to about 300 machine direction impression knuckles per 6.45 cm (1 square inch) which are raised above the plane of the fabric. These impression knuckles create corresponding protrusions in the throughdried sheet which impart a significant amount of cross-machine direction stretch to the sheet. In addition, other properties such as bulk, absorbent capacity, absorbent rate and flexibility are also improved.

摘要： A method of making a fabric-creped absorbent cellulosic sheet is provided which includes dewatering a papermaking furnish and partially drying the web without wet-pressing before applying it to a translating transfer surface moving at a first speed. The process further includes fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, the creping step occurring under pressure in a creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the surface and redistributed on the creping fabric. After creping, the web is dried, preferably with a plurality of can dryers to a consistency of at least about 90 percent while it is held in the creping fabric.

摘要： An absorbent cellulosic sheet is formed by belt creping a nascent web at a consistency of 30% to 60% utilizing a generally planar perforated polymeric creping belt to form a sheet with fiber enriched higher basis weight hollow domed regions on one side of the sheet joined by a network of lower local basis weight connecting regions forming a network where upwardly and inwardly inflected consolidated fibrous regions exhibiting CD fiber orientation bias form transition areas between the connecting regions and the domed regions. When formed into roll products, the cellulosic sheets exhibit a surprising combination of bulk, roll firmness, absorbency and softness. The consolidated fibrous regions are preferably saddle shaped and exhibit a matted structure on both their outer and inner surfaces.
