A breathable liquid-impervious composite sheet of a comfortable touch which is free from generation of fibrous waste. The composite sheet includes opposite surfaces of a breathable liquid-impervious sheet made of thermoplastic synthetic resin which are covered with continuous fibers.

Breathable liquid-impervious composite sheet

Pants that include a pair of outer sheets, and an inner sheet folded along a transverse center line, and disposed between lower parts of the respective outer sheets. Each of the outer sheets has upper and lower end portions extending in a transverse direction and front and rear side edge portions extending in a longitudinal direction while the inner sheet has lower end portions extending below the transverse center line in the transverse direction and a panel in the vicinity of the transverse center line. The inner surfaces of the respective outer sheets are bonded to each other in the vicinity of upper portions of the front and rear side edge portions thereof while the inner surfaces of the respective outer sheets are bonded to the inner surface of the inner sheet in the vicinity of lower portions of the front and rear side edge portions as well as in the vicinity of the front and rear side edge portions of the inner sheet.

Disposable pants of trunks-type and process for making the same

A fastening system for a garment such as a disposable diaper includes a hook panel having a plurality of hook elements and a loop panel having a plurality of loop elements. The hook panel includes a base panel having a top surface on which the hook elements extend and a back surface. The back surface of the base panel has a secured region and a non-secured region with respect to the garment. The non-secured region is defined toward one end from which the hook panel can be progressively released from the loop panel toward the other opposite end. The fastening system thereby reduces the chance that the hook panel might be readily and unintentionally released from the loop panel during use of the garment.

Fastening system for garment

A disposable gown is composed of a basic trunk portion having front and rear trunk regions and both sleeves, wherein the rear trunk region includes first and second rear trunk halves. Collar elements, by which the first and second rear trunk halves may be kept closed is formed from a front collar member attached to the front trunk region and surrounding front half of a neck opening, a first rear collar member attached to the first rear trunk half and surrounding rear half of the neck opening, and a second rear collar member attached to the second rear trunk half and surrounding rear half of the neck opening. Two pairs of engaging fasteners are formed on respective ends of the front collar member and the first and second rear collar members. The engaging fasteners detachably fasten the collar members to each other.

Disposable gown

A trunks-type garment has crotch region formed by two sheets that are superposed and bonded together. Extensions of these two sheets extending from a bottom of the crotch region of the garment are folded back onto the respective sheets of form lapels.

Trunks type wearing article

Trunks-type disposable pants that include a pair of inner sheets and a pair of outer sheets. The inner sheets have cutouts depressed from the upper ends toward the lower ends and liquid-absorbent panels attached to opposed surfaces of the inner sheets in the vicinity of the respective cutouts. The opposed surfaces of the inner sheets may be bonded together by means of bond lines extending in parallel to the cutouts and partially extending below the liquid-absorbent panels. Opposed surfaces of the inner sheets and the outer sheets are bonded together along the front and rear side portions of these sheets.

Trunks-type disposable pants

Pants that comprise a pair of intermediate body sheets, positioned in plane symmetry to each other and respectively contoured by upper, lower, inner and outer edges, and a pair of lateral body sheets also positioned outside the respective intermediate body sheets and respectively contoured also by upper, lower, inner and outer edges. Each of the intermediate body sheets is formed between the inner and outer edges with an arcuate cutout extending convexly from the upper edge, toward the lower edge the intermediate body sheets being put flat and sealed together along a sealing line defined by the cutouts but leaving a narrow marginal edge free. The intermediate body sheets and the lateral body sheets are placed flat and sealed together along sealing lines defined by inner and outer edges thereof, leaving narrow marginal regions free outside the inner and outer edges.

Throwaway trunks type underpants

Medium members such as thread are provided between woven fabric sheet such as warp knitting serving as the other sheet and base member, forming linear raised portions in the woven fabric sheet. The density of woven fabric sheet at the inclined portions to either side of these raised portions becomes coarse and the gaps between fine filaments on the woven fabric sheet spread, so that retaining heads of one sheet can easily enter and so that the fine filaments easily become hooked to the base portion of the retaining heads. Consequently, the retaining of the one sheet and the other sheet in strengthened, and the peeling strength is improved.

Retaining fastener and diaper using the fastener

A disposable training pant 1 includes a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core disposed therebetween. The liquid-permeable tophseet includes an upper layer sheet and a lower layer sheet. The upper layer sheet is formed with a wetness telling area and the lower layer sheet intermittently bonded to the absorbent core 13 and containing fibrous material adapted to shrink by 10% or more longitudinally of the training pant as it is wetted and intermittently bonded to the absorbent core and thereby intensify a feeling of wetness given to the infant.

Disposable training pants

Here is disclosed air-permeable and liquid-impermeable backsheet for use in body fluid absorbent articles. Polyolefin plastic sheet containing inorganic filler particles is stretched and then thermo-embossed to obtain the backsheet 1. At least one surface of this backsheet 1 is composed of a rough surface zone 5 and a smooth surface zone 6 so that these two kinds of zones define together a desired surface pattern over the backsheet. The rough surface zone 5 has fine pores 7 for air-permeability and the smooth surface zone 6 facilitates an absorbent core of the body fluid absorbent article to be seen through this smooth surface zone 6.

Air-permeable and liquid-impermeable backsheet for use in body fluid

The present invention relates to a disposable garment for catching body fluids or excretions and particularly to a garment provided with a plurality of flaps extending longitudinally side-by-side along laterally opposite sides of the garment and normally biased by their own elastic shrinking potential to turn up.
