Elastic non-woven lamination method and apparatus
A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.
ABSORBENT ARTICLE
An absorbent article, containing a topsheet, a backsheet, and an absorbent body interposed between the topsheet and the backsheet, in which the topsheet has an arrangement portion of a liquid film cleavage agent in a thickness intermediate position.
ELASTIC MEMBER, DISPOSABLE WEARING ARTICLE INCLUDING ELASTIC MEMBER, AND METHOD OF MANUFACTURING ELASTIC MEMBER
An elastic member has an elastic sheet stretchable structure in which an elastic sheet is interposed between a first sheet layer made of a nonwoven fabric and a second sheet layer made of a nonwoven fabric. The first sheet layer and the second sheet layer are welded through joint holes penetrating the elastic sheet at a plurality of sheet joined portions arranged at intervals, in which a region having the elastic sheet stretchable structure includes sheet joined portions having different shapes. In the sheet joined portions in the region having the elastic sheet stretchable structure, a reference bonding diameter is 0.2 mm or more, a maximum value of the reference bonding diameter is 1 to 3 times a minimum value thereof, and a circumference length is 1 to 15 times a length of a circumference of a circle whose diameter is the reference bonding diameter .
ABSORBER AND ABSORBENT ARTICLE
An absorbent member (1) according to the present invention includes: an absorbent sheet (2) that includes a substrate layer (20) and an absorbent layer (21) that includes water-absorbent polymers (P1) that are fixed to one side of the substrate layer (20); and an entangled fiber layer (3). The water-absorbent polymers (P1) of the absorbent layer (21) and the entangled fiber layer (3) are adjacent to each other. The water-absorbent polymers (P1) of the absorbent layer (21) are preferably fixed to one side of the substrate layer (20) using a hot melt adhesive. The absorbent member (1) configured as described above has excellent absorbency and shape stability while being thin.
APPARATUS FOR PRODUCING SANITARY ABSORBENT ARTICLES COMPRISING A PERFORATING DEVICE OF A WEB AND PROCESS
An apparatus for producing sanitary absorbent articles comprising at least one perforating device of at least one web intended for making sanitary absorbent articles capable of making perforated patterns spaced apart along the extension of the web, that is, in phase. The present invention also relates to a perforating process implemented in an apparatus for producing sanitary absorbent articles.
Method for manufacture of absorbent article
The purpose of the present invention is to provide a method for manufacture of an absorbent article, with which it is possible to form a desired coloring pattern upon an absorbent article and to reliably manage the quality of said coloring pattern. Provided is a method for manufacture of an absorbent article, in which: microcapsules, which are provided upon a substrate and in which coloring agents are enclosed, are destroyed in a prescribed pattern, and the coloring agents discharged upon the substrate; and the substrate is coated with a developer, causing the coloring to be expressed in the prescribed pattern via a reaction between the coloring agents and the developer.
Low friction core-shell nanofibrous membranes for delivery of active ingredients to the wet skin
A membrane for skin comprising a plurality of randomly oriented core-shell nanofibers is provided in the present invention, where each of said core-shell nanofibers comprises at least an active-ingredient-loaded polymeric core and a non-polymeric shell consisting of active ingredients only surrounding the core. Related fabrication method of said membrane is also provided in the present invention.
PROCESS FOR MAKING THREE-DIMENSIONAL FOAM-LAID NONWOVENS
A method for making a high topography nonwoven substrate includes generating a foam including water and synthetic binder fibers; depositing the foam on a planar surface; disposing a template form on the foam opposite the planar surface to create a foam/form assembly; heating the foam/form assembly to dry the foam and bind the synthetic binder fibers; and removing the template from the substrate after heating the foam/form assembly, wherein the substrate includes a planar base layer having an X-Y surface and a backside surface opposite the X-Y surface; and a plurality of projection elements integral with and protruding in a Z-direction from the X-Y surface, wherein the projection elements are distributed in both the X- and Y-directions, and wherein the density of a projection element is the same as the density of the base layer.
APPARATUSES AND METHODS FOR MAKING ABSORBENT ARTICLES
Aspects of the present disclosure relate to methods and apparatuses for manufacturing absorbent articles, wherein discrete zones of protrusions may be formed on a substrate. In some configurations, the protrusions may be formed as hooks. When forming the discrete zones of protrusions, localized speed variances may be imparted to the advancing substrate to ensure the adequate time to form the protrusions is provided. As such, protrusions may be formed on portions of the substrate that have been temporarily stopped or slowed to relatively slow speeds. The substrates with zones of protrusions may then be incorporated into products, such as assembled absorbent articles, so as to place the protrusions in desired positions on the absorbent articles. As such, the methods and apparatuses herein allow for the use of hook forming techniques on substrates in article manufacturing processes that provide flexibility in such configurations without sacrificing desired manufacturing speeds.
