  • Patent number: 9084698
    Abstract: A diaper has an outer sheet and a crotch member which includes a pair of skin-contactable sheets spaced from each other in a transverse direction. Inner side edges of the respective skin-contactable sheets cooperate with respective second ends of front and rear waist members to define an opening. A plurality of crotch elastic members is attached to the inner side edges. Under the effect of these crotch elastic members, a length dimension of the skin-contactable sheets is substantially reduced. The inner side edges of the skin-contactable sheets are spaced from the outer sheet in a thickness direction to form a space between the skin-contactable sheets and the outer sheet. A liquid-absorbent structure is provided in the space and includes a fold formed by folding the structure along a folding line. A top of the fold is bonded to the inner side edges of the respective skin-contactable sheets.

    Abstract: The invention is directed to a planar pad manufactured from three layers, each layer made from materials of differing properties. A contact layer being safe for a neonatal infant's skin is the top layer. The middle layer is an absorption layer positioned immediately below the contact layer. The absorption layer is of a two-part construction having a first half and a corresponding second half which abuts the first half. The absorption layer is operable for dispersing and containing fluids within the pad. The bottom layer is a waterproof barrier layer which is posited directly below the absorbency layer, preferably constructed of flashspun high-density polyethylene, and is also a two part construction. An internal pull tab maintains the pad in a single assembly. Upon removing the pull tab, the pad assembly splits into two separate assembly halves.

    Abstract: A bodily fluid absorbent matrix adapted to restrict a wet feeling against the wearer's skin after the absorbent matrix in a bodily fluid absorbent wearing article having absorbed bodily fluids and a method for manufacturing the absorbent matrix. A bodily fluid absorbent wearing article has an absorbent matrix formed of aggregate of bodily fluid absorbent material between a liquid-permeable first sheet and a liquid-impermeable second sheet. The member includes hydrophilic fibers as the bodily fluid absorbent material. Density of the absorbent matrix changes so as to increase from the first sheet toward the second sheet in thickness direction of the absorbent matrix. A planar orientation index of the hydrophilic fibers also changes so as to increase in the thickness direction of the absorbent matrix.

  • Publication number: 20140163500
    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: 20140163504
    Abstract: An absorbent article (20) having an absorbent core comprising at least about 80% of superabsorbent polymers (SAP) by weight of its absorbent material. An acquisition-distribution system (ADS) (50) is at least partially disposed between the absorbent core and the topsheet. The ADS extends in the longitudinal direction of the absorbent article at least from a point A1 disposed at a distance D from the front edge to a point A2 disposed at a distance D from the back edge of the article, D being equal to 32% of the length L of the article. The ADS has a basis weight which may be at least 20% lower at the point A2 than at the point A1.

  • Publication number: 20140141970
    Abstract: An absorber containing non-wood pulp with the settling velocity in water between 2 and 5 seconds, the mean fiber size of 8 to 25 ?m, the apparent bulk density of 0.04 to 0.07 g/cm3, and the absorption for 0.9% physiological saline of at least 20-fold with respect to the pulp mass. The absorber has a thickness change of at least 600%, as the thickness after having absorbed 0.9% physiological saline with respect to the thickness before absorbing 0.9% physiological saline. When addition of 80 mL of 0.9% physiological saline to the absorbent article over a period of 10 seconds is performed three times every 10 minutes and the absorption rate of the absorbent article for each of the three times is evaluated as the time from addition of the 0.9% physiological saline until complete absorption, the absorption rate for each of the three times is not greater than 20 seconds.

  • Publication number: 20140121622
    Abstract: Disclosed herein is a cellulosic textile filament made from microfibrillar cellulose fibers and a thickening agent as well as the precursor dope for forming such filaments, nonwoven webs made from such cellulosic textile filaments and the process for forming such filaments and nonwoven webs including such filaments. One of the advantages of these filaments is the eco-sensitive way in which they are made as they utilize a water-based dope that does not require any chemical solvents unlike other processes such as those used to make Lyocell fibers. In addition, the process does not involve any washing or extraction steps and it employs a cellulosic fiber source that is broadly based and renewable.
