摘要:
A method for making disposable absorbent articles which includes cutting a sheet into two elongated webs so that one edge of each web is straight and the other edge has alternating concave and convex portions, affixing the webs to a water-impervious backing sheet so that the straight edge portions thereof face each other and the alternating concave-convex portions face outwardly.

Provided is a method for producing a functional material, including the steps of: bringing a polyvalent metal cation aqueous solution into contact with a base material; bringing a polyanion aqueous solution containing a functional component into contact with the base material previously in contact with the polyvalent metal cation aqueous solution to bond the polyvalent metal cations and the polyanions to each other, and thereby forming an insoluble compound containing the functional component; and drying the base material including the insoluble compound.

An absorbent member comprises an absorbent core, a liquid permeable covering sheet and a reticulated sheet interposed between the absorbent core and the covering sheet 11, wherein the reticulated sheet has a relatively higher open ratio over at least an inwardly facing surface of the absorbent core than over any of oppsite side regions and opposite end regions thereof.

Bulky split fibers having bond strength are produced by preparing a composite synthetic resin film of three layer structure having a polypropylene layer formed of a polypropylene/polyethylene blend and a polyethylene layer on either surface of the polypropylene layer, slitting and stretching the composite film to thereby form stretched tapes, and causing splitting of the stretched tapes for fibrillation. An integral article is prepared from the resultant split fibers by mixing them alone or with plant fibers and then heating at a temperature between the melting points of polyethylene and polypropylene, thereby integrating together the split fibers with each other or with the plant fibers.

A disposable diaper is disclosed. This diaper includes an absorbent body forming a layer thicker in a crotch area than in the rest area, said thicker layer of the absorbent body defined in the crotch area pressed along both sides thereof, and elastic members located on both sides of the crotch area each made of a relatively wide material.

Disclosed is an absorbent article including: a liquid permeable surface structural body; a backing sheet; an absorbent core disposed between the surface structural body and the backing sheet. The surface structural body is formed by stacking bundles of continuous filaments into at least two layers and partially fixing the continuous filaments of the respective layers together. The individual continuous filaments extend over the entire length of the respective layers. The layers include: a lower layer positioned adjacent to the absorbent layer; and an upper layer positioned away from the absorbent layer and having a smaller width than that of the lower layer. The upper layer is located exclusively at a center portion or laterally opposite side portions of the lower layer.

There is disclosed an absorbent article including: a liquid permeable surface sheet; a backing sheet; and an absorbent layer located between the surface sheet and the backing sheet. The backing sheet includes a liquid impermeable base sheet and a layer of continuous filaments individually extending along a longitudinal direction of the absorbent article and stacked on an outer surface of the base sheet. The base sheet and the continuous filament layer are partially fixed.

A disposable sanitary garment includes a chassis defining an outer surface thereof, the chassis is provided along its transversely opposite side edge portions destined to extend around a wearer's thighs with a pair of first leg-hole elastic members extending circumferentially around the thighs and with a pair of second leg-hole elastic members describing a circular arc being convex inwardly of the garment. The chassis is folded back inwardly of the garment along one side edges of the respective members with the second leg-hole elastic members inside and a portion of the chassis extending inside the zone along which the chassis has been first folded back is folded back along the other side edges of the respective members.
摘要:
A web intended to be used as a topsheet or a backsheet defining front and rear sections and a crotch section extending therebetween in a disposable garment is continuously fed in its longitudinal direction, and a width of the web is divided in two halves along a longitudinally extending cutting line describing a curve approximate to a sine curve in and thus two webs are obtained. These two webs are transversely spaced from each other by a predetermined dimension and one of these two webs is longitudinally shifted relatively to the other by 1/2 period. Thereafter, these two webs are joined together in their overlapping regions. The two webs thus joined together is cut for every period with each pair of such overlapping regions lying in a middle of this period. The invention can thereby provide the topsheet or the backsheet without any waste pieces cut therefrom.
