Embodiments of the present disclosure relate to arrangements for simulating creping of tissue and methods for simulating creping of tissue.

Arrangement and method for simulating creping of tissue paper

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.

Absorbent materials, products including absorbent materials, compositions, and methods of making absorbent materials

The invention relates to a method and arrangement for detecting free fiber ends in a paper surface. The method comprises illuminating a target sample () surface, which comprises free fiber ends, from at least two directions one at the time, with at least one light source (). Original reflectance images are obtained for the target sample () surface with an imaging device (), 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.

Method and arrangement for detecting free fibre ends in paper

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.

Method of characterizing creped materials

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.

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.

Embossed nonwoven fabric

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.

Multiple mode headbox

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.

Soft and bulky composite fabrics

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.

Apparatus and method for controlling concentration gradients

The present invention desirably provides a fabric including a synthetic fiber structure first zone, a synthetic fiber structure second zone, and a short fiber third zone. The first zone may include a spunbond web layer and a meltblown web layer. The synthetic fiber structure second zone may be positioned proximate to the synthetic fiber structure first zone and the short fiber third zone may be positioned substantially between the first and second zones. Desirably, the first and second zones are entwined.

Method for making a hydraulically entangled composite fabric

An improved cloth-like base web is disclosed. In particular, the base web of the present invention has a cloth-like look and feel and has improved absorbency. The base web is made by first hydroneedling a web containing pulp and/or staple fibers. A bonding material is then applied to at least one side of the web and the web is creped on at least one side. By combining a hydroneedling operation with a creping operation, a base web is produced that is strong, stretchable, very soft and absorbent.

Cloth-like base sheet and method for making the same

A process for treating a fibrous material which includes the steps of: 1) providing a liquid suspension composed of fibrous material; 2) intermixing the liquid suspension of fibrous material with a treatment over a time period T,&mdash;wherein the treatment requires a period of time T,sufficient to treat the fibrous material; 3) depositing the liquid suspension of fibrous material and intermixed treatment onto a forming surface to form a layer and removing a substantial portion of the liquid, over a perod of time T,; and 4) applying pressurized jets of a liquid to the layer of fibrous material to wash unused treatment from the fibrous material within a period of time T,. Periods of time T,, T,and T,are immediately consecutive and amount to a total period of time at least as great as T,. Also disclosed is a hydraulically entangled structure composed of: 1) at least one layer a wet-laid nonwoven web containing fibrous cellulosic material; and 2) colorfast dye imparting color to the fibrous cellulosic material such that the fibrous cellulosic material is colorfast.

Fabric

A flame retardant composition for treating a high pulp content nonwoven web is provided. The flame retardant composition includes soluble solids formed from inorganic salts, such as ammonium polyphosphate and sulfur. The TGA range of such soluble solids is from about 175.degree. C. to about 370.degree. C. The flame retardant composition may be continuously and uniformly applied to the high pulp content nonwoven web by a non-compressive process.

Flame inhibitor composition and method of application

A method of making a nonwoven composite material. The method includes the steps of: providing a hydraulically entangled web containing a fibrous component and a nonwoven layer of substantially continuous filaments; applying a bonding material to at least one side of said web; and creping said at least one side of the hydraulically entangled web. The bonder material may be an aqueous mixture including a curable latex polymer, a pigment, and a cure promoter. Also disclosed is a nonwoven composite material made of a hydraulically entangled web including a fibrous component; a nonwoven layer of substantially continuous filaments; and regions containing bonder material covering at least a portion of at least one side of the composite material, wherein at least one side of the web has been creped.
