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.

摘要： A multi-ply flushable wipe includes a ply having first and second exterior layers and a middle layer disposed therebetween. Each of the exterior layers includes at least 50% by weight natural fibers. When foam-formed, the middle layer includes at least 25% by weight natural fibers. In embodiments, the middle layer may include at least 75% by weight natural fibers. The middle layer also includes synthetic fibers that have a length within the range of 1 mm and 20 mm. The wipe may have a length weight weighted average fiber length of less than 4 mm and a wet CD strength of greater than 20 N/m. Each ply of the wipe may be formed by wetlaying the first and second exterior layers and a foam formed middle layer to form a web, imprinting the web with a structured fabric, and drying the web. The plies are then attached using a binder.

摘要： A method of manufacturing an absorbent sanitary paper product having a machine direction, a cross-machine direction orthogonal and co-planar thereto, and a Z-direction orthogonal to both the machine- and cross-machine directions is disclosed. The method provides the steps of: providing a first and second network of fibers each having opposing first and second sides where each fiber of the first network of fibers has a longitudinal axis generally disposed within the plane comprising the machine- and cross-machine- directions; applying a first bonding layer to one of the first and second sides of the first network of fibers; applying a first second network of fibers to the first bonding layer; and, placing the first and second network of fibers into face-to-face contacting engagement.

摘要： The disclosure provides tissue webs, and products incorporating the same, where the webs comprise macroalgae fibers. More specifically the disclosure provides soft and durable tissue webs comprising at least about 1 percent macroalgae fiber by weight of the web. In the tissue webs of the present disclosure, macroalgae fibers may preferably replace high average fiber length wood fibers, which increases the strength and durability of the web without negatively stiffness.

摘要： A high efficiency disposable cellulosic wiper includes (a) pulp-derived papermaking fiber; (b) up to 75% by weight regenerated cellulosic microfiber having a characteristic CSF value of less than 175 ml, the microfiber being selected and present in amounts such that the wiper exhibits a Laplace pore volume fraction at pore sizes less than 15 microns of at least 1.5 times that of a like wiper prepared without regenerated cellulose microfiber. The wipers of the invention exhibit remarkable residue removal efficiency.

摘要： A method of making a fabric-creped absorbent cellulosic sheet comprising: a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber; b) applying the dewatered web having the apparently random fiber distribution to a translating transfer surface moving at a first speed; c) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping fabric, the creping step occurring under pressure in a fabric 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 transfer surface and redistributed on the creping fabric to form a web with a drawable reticulum.
