  • Patent number: 9000254
    Abstract: A disposable diaper is disclosed having reduced bulk, especially in the back waist region. Due to an opaque topsheet and a backsheet having a relatively high percentage of printed surface area, the diaper has reduced see-through even in those areas of the back waist region where no absorbent core is comprised.

  • Patent number: 8979815
    Abstract: The present disclosure is directed, in part, to an absorbent article that comprises an absorbent core disposed at least partially intermediate a topsheet and a backsheet and a core wrap enclosing an absorbent material. The core wrap comprises a first material and a second material. The first material forms a C-wrap at least partially around the second material. The absorbent material comprises at least 80% of superabsorbent polymers by weight of the absorbent material. The absorbent core comprises a channel substantially free of the superabsorbent polymers, at least partially oriented in a longitudinal direction of the article, and comprising an arcuate portion. The channel has lateral widths taken parallel to a lateral axis of the article. The profile of the lateral widths of the channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant.

  • Publication number: 20150057629
    Abstract: An absorbent article includes a body side liner, a back sheet, an absorbent body positioned between the body side liner and the back sheet, and a body conforming structure positioned in direct facing relation with the body side liner. The body conforming structure length is at least 50% the absorbent body length and is aligned with a longitudinal centerline of the absorbent article. The median anterior portion width of the body conforming structure is greater than the median central portion width of the body conforming structure which is greater than the median posterior portion width of the body conforming structure. The anterior portion includes a well, the central portion includes a channel, and the posterior portion includes a taper. The well transitions into the channel via a first convex transition and a concave transition. The channel transitions into the taper via a second convex transition.

  • Publication number: 20150032069
    Abstract: A wound dressing for covering a wound includes a textile layer woven by polyacrylonitrile-based activated carbon fiber, and an absorbent layer provided on one side of the textile layer away from the wound. The activated carbon fiber is produced by polyacrylonitrile oxidized fiber in a moisturized carbon dioxide atmosphere at the temperature of 700° C. to 1200° C. for 1 to 60 minutes. The material of the absorbent layer is cotton, alginate, poly vinyl alcohol, or a combination thereof. The water absorbing ability of the absorbent layer is superior to that of the textile layer. Because the textile layer does not produce dust and can keep dry, the hard-to-heal wounds can be prevented.

  • Publication number: 20150018794
    Abstract: Provided is an absorbent article having a top sheet with an opening-formed area in which openings are formed, and non-opening-formed areas in which no openings are formed, said absorbent article being capable of preventing liquid from remaining on the surface of the opening-formed area of the top sheet. In the present invention, the top sheet is a resin sheet having an opening-formed area (12) in which openings are formed, and non-opening-formed areas (5, 14) in which no openings are formed. The opening-formed area (12) is disposed in an outlet-facing area (16) that faces at least an outlet for fluid from a wearer. The top sheet (2) has a blood modifier layer on the surface of at least the outlet-facing area (16). The blood modifier of the blood modifier layer has an inorganic/organic balance (IOB) of 0 to 0.60, a melting point of not more than 45° C., and an aqueous solubility of 0.05 g or less with respect to 100 g of water at 25° C.

  • Publication number: 20150005728
    Abstract: A disposable diaper having front and rear augmented waistband zones having a specified size and stiffness is disclosed. For relatively thinner, less bulky diapers of currently marketed designs, providing augmented waistband zones is believed to reduce mental and physical effort for the caregiver in application of the diaper. The augmented waistband zones provide a robust-feeling structure proximate the waist edges, which the caregiver may grasp at front and rear to adjust the diaper on the wearer. Caregiver perception of a need to reach deeper into the diaper structure to grasp it at a thicker area to tug at it is believed to be reduced.

  • Publication number: 20140378929
    Abstract: A hydrophilic dressing including a base layer, a hydrophilic dressing layer and an anti-sticking layer is provided. The hydrophilic dressing layer is disposed on the base layer. The anti-sticking layer covers on a part of the hydrophilic dressing layer. While the hydrophilic dressing layer absorbs a great amount of exudate from wound, the anti-sticking layer of the hydrophilic dressing can separate avalanched hydrophilic dressing from skin. Therefore, when the hydrophilic dressing is removed, the avalanched hydrophilic dressing would not remain on the skin.
