  • Patent number: 12037266
    Abstract: A specially functionalized composite filter material with a high specific surface area is used to adsorb PFAs from potable water. In a preferred embodiment, the base filter material is granular activated carbon (GAC), which is sequentially coated with a thin layer of polydopamine, a thin layer of partially oxidized iron, and a thin coating of octadecylamine. After PFAs are adsorbed onto the coated GAC particles, the PFAs are removed by a rinsing process, and remain in the rinse effluent. GAC particles are recovered and recoated as needed to restore their adsorptive capacity. The PFA-containing effluent is treated using photochemical processes to destroy the PFA molecules. The now PFA-free effluent can be disposed of as a non-hazardous material. The composite filter material works in systems ranging from small passive systems for personal use to large scale, high-flow-rate utility water treatment systems.

  • Patent number: 8847002
    Abstract: An absorbent article that contains a topsheet having embossed regions is provided. The embossed regions propagate in a longitudinal direction of the article in the form of a wave having one or more alternating crests (peaks) and troughs (valleys). Such a wave pattern helps slow down the flow of bodily fluid by directing it along a tortuous path defined by the densified edges rather than in a straight line. Among other things, this reduction in flow rate can help provide sufficient time for the absorbent core to absorb the fluid, which is particularly helpful when it is already partially filled with fluid. Nevertheless, bodily fluids can still sometimes pool near the crests and/or troughs and result in leakage. To help counteract this tendency, the present inventors have discovered that a plurality of apertures can be employed in the topsheet that are arranged in a column that generally extends in a longitudinal direction of the article.

  • Patent number: 8664469
    Abstract: A disposable absorbent article has front and back panels, each having an elastic film layer and each having first and second zones. The first zone of each panel is extensible and retractable and the second zone of each panel is non-extensible and non-retractable. Each of the front and back panels has first and second side edges. An absorbent assembly is secured to the front and back panels. The absorbent assembly has a first end secured to the second zone of the front panel and a second end secured to the second zone of the back panel. A pair of seams join the front and back panels together at the first and second side edges to form a disposable absorbent article having a waist opening and a pair of leg openings.

  • Publication number: 20140031779
    Abstract: An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent article comprises a first fluid handling zone having a first Transverse Fluid Travel Distance and a second fluid handling zone having a second Transverse Fluid Travel Distance. The first Transverse Fluid Travel Distance is at least about 50% greater than said second Transverse Fluid Travel Distance, which results in an absorbent article that is better able to handle bodily fluids and reduce the risk of accidental leakage of bodily fluids onto a consumer's undergarments.

  • Patent number: 8633347
    Abstract: An absorbent element for the absorption of body fluids in sanitary articles comprises a first layer of sheet material presenting an array of hollowed formations (16) with respective mouth parts, as well as masses (18) of superabsorbent material that is able to expand as a result of the absorption of body fluid, which are set in the aforesaid hollowed formations (16). A second layer of sheet material (12) is applied on the first layer of sheet material (10) so as to cover the mouth parts of the hollowed formations (16). At least one of the layers of sheet material (10, 12) is permeable to body fluids to enable the body fluids themselves to penetrate into the hollowed formations and be absorbed by the masses of superabsorbent material (18) that expand in the hollowed formations (16), creating a first level of absorption of body fluids.

  • Patent number: 8614365
    Abstract: An absorbent article having a topsheet having a first portion and a second portion. The topsheet has a longitudinal centerline and a transverse centerline. The topsheet has an area. The second portion can differ in structure from the first portion. The second portion can have a structurally modified zone. The structurally modified zone has a periphery, a length, and a long axis. The length is the maximum straight-line dimension between two points on the periphery. The long axis extends between two points on the periphery separated by the length. The long axis of the structurally modified zone can be asymmetric to the longitudinal centerline. The structurally modified zone can make up more than about 5% of the area of the topsheet. The topsheet can have a lotion zone, the long axis of which is asymmetric to the longitudinal centerline and the transverse centerline.

  • Patent number: 8603053
    Abstract: The invention relates to a liquid-permeable primary dressing in the form of a supple thermoplastic section of material (1.4), comprising: a first smooth surface (4); a second surface (5) facing away from the smooth surface (4); and a plurality of three-dimensional perforations, whose walls extend from the first smooth surface (4) and end in an overhang with a free edge, thus making the second surface (5) rough to the touch. At least one of the free edges has an angled section that is approximately perpendicular to a perforation axis. In a preferred embodiment, the periphery (13) of the material section is smooth on both sides, i.e. on both the first and second surfaces (4; 5), the periphery (13) of the surface (5) that was at first rough being thermally smoothed.
