APPARATUS AND METHODS FOR TRANSPORTING WEBS OF MATERIAL
Methods and apparatus for transporting either an entire web or discrete components of disposable products such as diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this layer, and the machine provides sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.
Wound dressing
The present application is concerned with an improved wound dressing for use in the treatment of skin wounds with some level of exudation, especially for use in those wounds which are infected or under risk of being infected by microorganisms.
A PACKAGE OF ABSORBENT UNITS AND A METHOD FOR MANUFACTURING SUCH A PACKAGE
The present disclosure relates to a package (1) of absorbent units (5; 11), said package (1) includes an outer enclosure (2) enclosing the absorbent units (5; 11) and being at least partially non-opaque, wherein the outer enclosure (2) has a thickness (t) which is not more than approximately 70 μm, wherein the outer enclosure (2) supports a first graphical item (3) and at least one of the absorbent units (5; 11) supports a second graphical item (9; 9′). Furthermore, the absorbent unit (5; 11) supporting said second graphical item (9; 9′) is configured so that the second graphical item (9; 9′) is positioned in a manner so that it is generally not visible for a viewer from outside the outer enclosure (2). The invention also relates to a method for manufacturing a package (1) of the above-mentioned type.
Clip on electronics module
A clip-on module having a specialized housing design, probe contacts, switches, various advertising modes, and various configurations of signal repeaters is disclosed. The module is utilized via attachment to a specialized garment worn by a human patient. To properly apply the housing to the garment, a user will squeeze the module to open using tactile features embedded within the housing, locate the module, and then press-clamp the module to close and attach it. A plurality of probe contacts within the module have sharpness requirements for penetrating one or more layers of the garment while still maintaining low resistance, and will work with a backing material for probe.
THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.
Absorbent disposable article comprising a porous polymer-based structure
An absorbent disposable article, such as a diaper, panty diaper, panty liner, sanitary napkin or incontinence device is disclosed. The article has a porous polymer-based structure obtainable by a process of: (a) depositing and photopolymerizing, layer-by-layer in accordance with a predetermined 3D model, an emulsion having an external continuous phase surrounding droplets of an internal phase having has one or more photopolymerizable monomers and/or oligomers and a photopolymerization initiator; and (b) removing the internal phase from the continuous polymer phase formed from the one or more photopolymerizable monomers and/or oligomers. The process produces a monolithic porous structure having three types of pores: (i) pores resulting from the location from which the internal phase was removed, (ii) pores interconnecting the pores according to (i), and (iii) pores as predetermined by the 3D model. The invention also relates to a method of making the article.
ARRAY OF DISPOSABLE PANT ARTICLES AND METHOD FOR PRODUCING AN ARRAY OF DISPOSABLE PANT ARTICLES
An array includes at least one first disposable pant article and at least one second disposable pant article. The first article has a first structure, and at least the outside surface and a surrounding zone of the absorbent core have substantially the same first colour. The second article has a second structure, and at least the outside surface and a surrounding zone of the absorbent core have substantially the same second colour. Each of the first and second articles includes an information tag arranged on the inside of the waist portion, the material of the information tag being in a third colour which is different from the first and second colours by a colour difference ΔE*ab more than 20. The first structure is structurally different from the second structure and/or the first colour is different from the second colour by a colour difference ΔE*ab more than 10.
Process for making fluid-entangled laminate webs with hollow projections and apertures
The present invention is directed to a process and apparatus for formation of a fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. The laminate web also includes a plurality of apertures interspersed with the projections. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in a forming surface thereby forming the hollow projections. The force of the entangling fluid also causes the fibers of the two layers to be moved around protrusions present in the forming surface thereby forming the apertures.
COMPOSITE HAVING IMPROVED IN-PLANE PERMEABILITY AND ABSORBENT ARTICLE HAVING IMPROVED FLUID MANAGEMENT
The present disclosure features a composite fabric, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.
ABSORBENT CORES COMPRISING FOAM MATERIAL
The present invention relates to absorbent cores for use in absorbent articles, preferably of the disposable personal hygiene type. It discloses absorbent cores comprising a foam layer incorporating a nonwoven fabric and having a top surface and a bottom surface, said foam layer top surface comprising one or more indented compressed portions and one or more raised non-compressed portions. The foam layer has openings extending through the foam and the nonwoven fabric. The absorbent core further comprises, joined to the bottom surface of the foam layer, a nonwoven comprising superabsorbent polymers. Absorbent cores of the present invention provide a fast acquisition of body exudates and a good liquid retention capacity. This is further achieved in a simple and cost-effective way without complex and considerable foam formulation and processing requirements.
