Method of making an absorbent composite and absorbent articles employing the same
A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.
Polymeric film exhibiting improved anti-blocking characteristics and process of making
A method of forming a film resistant to blocking including the steps of providing a polymeric film having a first and second surface; applying the anti-blocking agent in a fluid or molten state to at least the first surface of the polymeric film; and gathering the treated film. The anti-blocking agent may be substantially acrylic free.
STRIP OR LAP COMPRISING LOOPS, IN THE FORM OF A LAMINATE WITH PRINTED PATTERNS
The invention relates to a strip or lap comprising loops, in the form of a laminate with printed patterns. The laminate for forming a loop strip or lap, in particular the landing zone of nappies, includes at least one nonwoven layer having a lower face and an upper face opposite the lower face; at least one layer of ink applied to the upper face of at least the nonwoven layer; and at least one external textile layer from which loops project externally in order to engage with hooks of a self-fastening hook and loop device, at least one textile layer being secured to the upper face of at least the nonwoven layer.
Diapers having a zoned non-attachable back sheet and methods of manufacturing same
According to one embodiment, an absorbent article to be worn about a wearer has a front portion and a back portion. The absorbent article includes an outer layer, an inner layer that is substantially co-extensive with the outer layer, an absorbent layer and one or more fasteners, which are located on the back portion of the absorbent article. The absorbent layer is interposed between the outer layer and the inner layer to form the absorbent article. The outer layer has a central portion between two side portions. The central portion of the outer layer is treated with a chemical to substantially inhibit attachment of the one or more fasteners to the central portion of the outer layer. The one or more fasteners secure the back portion to the outer layer of the front portion. Specifically, the one or more fasteners are configured to secure the back portion to a region of the outer layer which is not treated with the chemical.
Absorbent article with klemm gradient and water repellent finishing
An absorbent member containing a hydrophobic material subjected to hydrophilic treatment, a plurality of through holes passing through the absorbent member in a thickness direction formed at a portion of the absorbent member in a target region (P). The absorbent member has a layer-stacked structure of a plurality of layers, stacked in the thickness direction. The Klemm water absorption height of a lower layer most proximal to the backsheet is higher than that of an upper layer most proximal to the topsheet. The backsheet contains a moisture permeable film including a plurality of microvoids, and having water repellent portions formed by water repellent finishing, on a portion in the target region (P) of a skin-facing surface of the moisture permeable film. A ratio of the total area of portions on which the water repellent finishing is performed to the area of the target region (P) is from 30% to 60%.
ABSORBENT PRODUCT
An absorbent product including a liquid-permeable top layer, a liquid-impermeable bottom layer and an absorbent core arranged between the top layer and the bottom layer is disclosed. The absorbent product has a head product portion, an intermediate product portion and a rear product portion extending in a longitudinal direction of the absorbent product. The absorbent product has an outer contour having a shape resembling an hourglass, wherein the intermediate product portion includes an area with a smaller width than any area in the head product portion and rear product portion, respectively, and wherein the core extends in the longitudinal direction and transverse direction of the absorbent product and has an outer contour that is asymmetrical with the outer contour of the absorbent product.
LIQUID BARRIER AND AIR-PERMEABLE BACKSHEET
Backsheets having a combination of desirable liquid barrier properties and air permeability are provided. The backsheets include outermost spunbond layers and two or more fine-fiber containing nonwoven layers.
Method of making an absorbent composite and absorbent articles employing the same
A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.
Biodegradable Absorbent Articles
A biodegradable, disposable absorbent article, such as a diaper, having a non-woven inner layer of natural fibers and a non-woven outer layer of natural fibers and a treatment applied to at least one surface thereof. The treatment includes at least one compound selected from the group consisting of waxes, urethanes, silicones, fluorocarbons, and non-fluorochemical repellents. The absorbent article has a core of natural fibers or fibrous material, and optionally polyacrylate superabsorbent particles, positioned between the inner layer and the outer layer. The article may contain polylactic acid films between the layers.
Diaper product adapted for collection of urine sample from an infant
A disposable diaper product useful for collecting a urine sample from an infant is disclosed. In one example the product may have a liquid control structure overlying a liquid impermeable backsheet, with a plan surface area defining a volume coextensive therewith, wherein a portion of the volume defined by at least 50 percent of the plan surface area contains no more than 50 percent by weight absorbent material. In another example the product may have a liquid control structure overlying a liquid impermeable backsheet, and have an average Liquid Release Ratio of at least 3 percent. A method for collecting a urine sample from an infant is also disclosed, in which a diaper is used for collection.
