摘要:
The present disclosure provides a disposable absorbent article including an inner part including a sheet of material having an inner side, an outer side opposite the inner side, a front waist region, and a rear waist region, wherein the front waist region is connected with the rear waist region to form a waist opening and two leg openings; an outer part including an absorbent material, the outer part being separate from the inner part and adapted to be worn over the outer side of the inner part such that the inner part can be worn independently of the outer part; and an opening in the sheet of material of the inner part for allowing bowel movement waste to pass through the opening so that the inner part cooperates with the outer part in use to collect and retain bowel movement waste between the inner and outer parts.

An open-type disposable diaper is composed, in its longitudinal direction, of a crotch region, a front waist region and a rear waist region. The rear waist region is provided on its transversely opposite sides with wings and lobes extend outward from these wings in a transverse direction. These lobes are provided on inner surfaces thereof with fasteners. Each of the lobes is divided in a section placed aside toward an outer end and a section placed aside toward an inner end as viewed in the longitudinal direction. The section placed aside toward the outer end has an elastic stretchability in the transverse direction of the diaper higher than the section placed aside toward the inner end. The fastener is attached to the section placed aside toward the outer end.
摘要:
A release liner providing a release surface which comprises a first olefin polymer film formed having dispersed therein by high shear mixing a release substance which is polyethyleneimine octadecyl carbamide, polyvinyl octadecyl carbamate or a mixture thereof, coextruded or cocast onto a film formed from a second olefin polymer. The release liner has particular utility in diaper tape application.
摘要:
A sanitary napkin having an improved release liner. The sanitary napkin includes a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. The backsheet has an inner surface and an outer surface. A pressure sensitive adhesive is positioned on the outer surface of the backsheet for securing the sanitary napkin in the crotch portion of a user's panty or undergarment. A release liner is releasably affixed to the adhesive in order to keep the adhesive from adhering to a surface other than the crotch portion of the panty prior to use. The release liner is a microapertured polymeric web.
摘要:
A freely peelable release part structure is disclosed. The tape or a like part associated with the structure is difficult to separate when it should be kept fixed. On the other hand, noise-free peeling thereof is easy when it should be peeled away. In particular, a release part structure useful for the fastening of diapers is provided. It contains a structure of a release part whose interfacial boundary is constituted by a pressure-sensitive adhesive layer (4) and a silicone-based release layer (2), characterized in that the adhesive layer comprises a tacky substance containing a rubber as a major component and the release layer comprises a silicone-based release agent containing a three-dimensional structure organopolysiloxane in an amount of 1-80% by weight.
摘要:
A method for forming a plurality of adhesive fastener assemblies includes the step of providing a substantially continuous web of substrate material along a selected, longitudinal machine-direction (132). The substrate web has a laterally extending cross direction (134) which is substantially perpendicular to the machine direction, and has laterally opposed, longitudinally extending side edge regions (142 and 144) thereof. A selected fastening means, such as a layer of primary adhesive (54), is positioned and applied onto a major facing surface (186) of the substrate web (140). A first longitudinally extending web of stiffening material (154) is attached to the major surface of the substrate web (140) at a location which is proximate a first side edge region (142) of the substrate web. A second longitudinally extending web of stiffening material (156) is attached to the major surface of the substrate web (140) at a location which is proximate the second side edge region (144) of the substrate web (140). The web of substrate material and the webs of stiffening material thereby form a substrate composite (192). The substrate web is separated along a longitudinally extending medial region thereof, with a substantially regularly undulating serpentine separation line (158) to provide an opposed pair of fastener tab subassemblies (194 and 196).
摘要:
An adhesive laminate structure composed of three layers is provided. A smooth thermoplastic film acts as a release liner without any release coating in combination with an acrylate adhesive and an oil-containing substrate.
摘要:
A baby''s napkin comprises a paper-thin backing sheet having a central crutch portion at the top of the sheet which is wider than a front portion at the bottom of the sheet, so that in use the ends of the back portion overlap end areas of the front portion, and one face of each pair of overlapping faces carries an area of pressure-sensitive adhesive protected by a strippable covering.
摘要:
A disposable sanitary napkin includes a main body and a pair of bridged flaps. The main body includes an absorbent system, a topsheet, and a backsheet, and it has a pair of side edges extending along the length thereof. The bridged flaps include a first straight edge, a second, shape-cut edge defining a projecting portion, and a bridging segment of a release liner having at least one zone of adhesive configured for attachment to the projecting portion of each bridged flap. Each bridged flap is attached to the main body with the first, substantially straight edge of each shaped strip aligned with a corresponding side edge of the main body, the bridged flaps are disposed over the topsheet, and each side flap is releasable from the bridging segment of the release liner.
