A water-absorbent structure comprises an assembly of thermoplastic synthetic fibers, cellulose-based fibers, super-absorbent polymer and water-pervious sheets wrapping these components together. The assembly is a honeycomb construction having a plurality of through-holes and normally in a compressed state. Upon water permeation into the water-absorbent structure, the super-absorbent polymer is swollen and softened and the assembly is swollen so that the through-holes restore the initial state before the assembly has been compressed.

A disposable diaper is improved so that a free portion of each tape fastener is reliably prevented from being disengaged from a target tape even an outer surface of the tape fastener and an inner surface of an underwear rub together during use of the diaper. A pair of tape fasteners 6 used to connect front and rear waist regions 8, 10 to each other are attached to side flaps 14 in a rear waist region 10 of a diaper 1A, respectively. In the diaper 1A, each of the tape fasteners 6 including first fibrous nonwoven fabric made of thermoplastic synthetic resin fiber and thermoplastic synthetic resin coated on a substantially whole area of an outer surface of the first fibrous nonwoven fabric wherein the thermoplastic synthetic resin forms a substantially smooth first synthetic resin layer on outer surfaces of the respective tape fasteners.

Disclosed is a water-disintegratable sheet including water-dispersible fibers and microfibrillated cellulose. The water-dispersible fibers are hydroentangled about each other to provide high fiber density regions and low fiber density regions. The hydroentangled water-dispersible fibers are bonded to each other through a hydrogen bonding power of the microfibrillated cellulose.

A composite sheet comprises a hydrophobic first plastic film layer forming an upper surface of the sheet, a second plastic film layer forming a lower surface of the sheet and a hydrophobic intermediate fibrous assembly layer disposed between these two layers. The first plastic film layer includes a plurality of first plane regions spaced one from another and extending parallel one to another in one direction and sawtooth-shaped first rising regions formed along edges of the first plane regions and the second plastic film layer includes a plurality of second plane regions. Such composite sheet is breathable but liquid-resistant and suitable for use for disposable garments.
摘要:
A composite sheet that includes a sheet-like fibrous assembly and a plurality of thermoplastic synthetic resin lamellae. Each of the film layer is formed on its upper surface with a plurality of grooves extending from one side edge to the other side edge of the film layer.

A topsheet for body fluids absorbent article is made of thermoplastic synthetic fibers mechanically entangled so as to extend substantially in a desired one direction and formed with liquid-permeable openings. The openings comprise a first group of openings each having a substantially oval shape defined by its major axis extending substantially in parallel to the direction in which the fibers extend and its minor axis extending orthogonally to the major axis and a second group of openings each having a substantially oval shape defined by its minor axis extending substantially in parallel to the direction in which the fibers 11 extend and its major axis extending orthogonally to the minor axis.
摘要:
A topsheet for body exudates absorbent article includes a hydrophilic nonwoven fibrous sheet and a plurality of thermoplastic synthetic resin filaments extending in one direction parallel to one another and continuously bonded to an upper surface of the nonwoven fibrous sheet so that a composite sheet of these sheet and filaments have crests and troughs alternately repeating longitudinally of the filaments and respectively extend transversely of the filaments. An apparatus and a method for manufcturing the topsheet are also disclosed, wherein a pair of mutually engageable embossing rolls are used for forming the crests and the troughs onto the coposite sheet.
摘要:
A topsheet of body fluid absorptive articles comprising a first sheet made of thermoplastic synthetic resin sheet and having liquid passages each downwardly extending therethrough and a second sheet containing 70 to 100% by weight of cellulose fibres bonded to said first sheet around lower openings of the respective liquid passages and comprises mechanically intertwined fibres only. The second sheet has a density higher than a density of fibres contained in the liquid-absorbent core.
摘要:
A topsheet for body fluid absorptive articles improved so that liquid passages formed in the topsheet may be stabilized during use of the goods and the topsheet may offer cloth-like feeling and appearance, the topsheet being composed of an upper sheet layer made from melt blown nonwoven fabric containing downwardly extending liquid passageways and an underlying fibrous layer 11 bonded thereto adjacent the lower openings of said liquid passageways, whereby the liquid passageways will not be collapsed and the lower openings of these passageways will not be distorted.
