Abstract: In various exemplary embodiments described herein, an absorbent structure (e.g., a paper material) having an applied absorbent material (e.g., an absorbent film) may be formed by treating a fiber (e.g., a cellulosic fiber) with an applied absorbent material forming system (also referred to as a “film forming system”), absorbent materials, compositions, methods of making absorbent materials, and the like.

Abstract: The invention relates to a method and arrangement for detecting free fiber ends in a paper surface. The method comprises illuminating a target sample (6) surface, which comprises free fiber ends, from at least two directions one at the time, with at least one light source (1). Original reflectance images are obtained for the target sample (6) surface with an imaging device (4), and a surface normal is estimated for each image pixel of the original reflectance image. Thus it is possible to reconstruct a reconstructed reflectance image from the estimated surface normals, and to compare the reconstructed reflectance image and the corresponding original reflectance image and to construct a difference image, where the differences represent shadow objects of the free fiber ends in a paper surface.

Abstract: Methods of characterizing the topography of a surface of a creped material, devices for characterizing surface topography of a creped material, computer systems for characterizing surface topography of a creped material, and the like, are disclosed.

Abstract: The invention relates to an arrangement for simulating creping of tissue. The arrangement comprises a sled with a test surface, which sled is arranged to travel along a linear path; heating means for heating the test surface; a spray unit with at least one spray nozzle, the spray unit being arranged along the linear path of the sled and the at least one spray nozzle being arranged to spray a chemical on the test surface; a creping unit comprising a creping blade, the creping unit arranged along the linear path of the sled after the spray unit and the creping blade arranged to pass over the test surface when the sled passes the creping unit; and measurement means for measuring data related to force between the creping blade and the test surface. The invention relates also to a method for simulating creping of tissue.

Abstract: A three-dimensional hydraulically entangled nonwoven composite structure made of nonwoven fibrous web and a fibrous material integrated in the nonwoven fibrous web by hydraulic entanglement is disclosed. The nonwoven composite structure has a greater ability to maintain an embossed pattern when wet and has the ability for the structure to recover after it has been compressed, to a greater degree than previously found. Also disclosed is a method of making an embossed hydraulically entangled nonwoven composite fabric.

Abstract: The present invention provides for a nonwoven web composite which contains at least 40% by weight of post consumer recycled materials. It has been surprisingly discovered that a nonwoven web composite of the present invention, with its fairly high post consumer recycled material content, has physical properties similar to those of a nonwoven web composite prepared from virgin materials.

Abstract: A multiple mode headbox is provided including a support surface, two or more chambers, and an adjustable roof. Each chamber includes a plurality of nozzles adapted to optionally supply papermaking fibers to the support surface. The adjustable roof is operably configured to adjust over a range of movement such that it defines a forming zone between the support surface and at least one chamber in a first mode, and between said support surface and at least one different said chamber in a second mode.

Abstract: A composite fabric is provided that contains staple fibers hydraulically entangled with a nonwoven web formed from continuous filaments. A portion of the staple fibers is entangled with the web, while another portion protrudes through the web. The resulting surface topography has one surface with a preponderance of the smooth, staple fibers, and another surface with a preponderance of the continuous filaments from the nonwoven web, but also including some of the protruded smooth, staple fibers. Thus, each surface contains smooth staple fibers and is soft.

Abstract: Disposable liquid absorbent mats are described. The mats generally include at least a liquid absorbent layer and a liquid impervious layer. The liquid absorbent layer may be made from a tissue web, a hydroentangled web, an airlaid web, a coform web, and the like. The liquid impervious layer, on the other hand, may comprise a meltspun web, a film, a hydroentangled web, or even a tissue web that has been treated with a sizing agent that renders the web resistant to fluid flow. In one embodiment, the mats can be made so as to have a relatively low caliper so that the mats can be spirally wound into a roll. In other embodiments, however, the mats may be packaged in a stacked arrangement. The mats have various uses and applications. For instance, the mats are well suited for use during food preparation. The mats are well suited to absorbing fluids while preventing the fluids from striking through the product. In some embodiments, the mats are also well suited to serve as an absorbent and cut resistant surface.

Abstract: The present invention discloses and claims a fill system and method for reducing the chemical concentration gradient in absorbent materials. The fill system includes a source of liquid connected to a nozzle for dispensing the liquid into a container. The nozzle includes a dispersal face that defines primary apertures approximately equidistant from the outer perimeter and center point on the dispersal face. The nozzle may also include secondary apertures proximate to the outer perimeter and one or more tertiary apertures proximate to the center point. The dispersal of fluid through the secondary or tertiary apertures may be less approximately one-half of the dispersal of fluid through the primary apertures.
