Description
DK 160074 BDK 160074 B
Den foreliggende opfindelse angår et hygiejnisk éngangsprodukt, især bleer, hygiejnebind og indlæg, og af den i krav l's indledning angivne art. Den angår specielt konstruktionen af disses dækbane.The present invention relates to a disposable hygienic product, in particular diapers, sanitary napkins and inserts, and of the kind specified in the preamble of claim 1. It particularly concerns the construction of their tire track.
55
Hidtil er hygiejniske éngangsprodukter og især bleer, hygiejnebind og sårkompresser blevet konstrueret med dækbaner af hydrofobt materiale. Dette materiale har forholdsvis lave fluidumti 1bagehoIdel ses- og fluidumti 1 bagestrømningskarakter i -10 stika, og forbedringer med hensyn til fluidumgennemtrængning er ønskelige, specielt til at forhindre lækage, når der er pludselige strømme af fluidum, såsom urin, menstruationsvæske og tilsvarende. De hydrofobe baner er hidtil blevet fremstillet af uvævede polyamid-, polypropylen-, eller polyesterfibre 15 eller blandinger af disse og disse hydrofobe dækbaner har haft et behov til at forbedre deres fluidumgennemtrængningsevne.To date, disposable hygiene products, and in particular diapers, sanitary napkins and wound compresses, have been constructed with hydrophobic material cover webs. This material has relatively low fluid backbone and fluid backbone character in -10 sockets, and improvements in fluid penetration are desirable, especially to prevent leakage when there are sudden streams of fluids such as urine, menstrual fluid and the like. The hydrophobic webs have heretofore been made of nonwoven polyamide, polypropylene, or polyester fibers or mixtures thereof and these hydrophobic cover webs have had a need to improve their fluid permeability.
Til dette formål anviser beskrivelsen til US-patentskrift nr. 3.814.101 brugen af en hydrofob dækbane, der har en serie af spalter, hvilke spalter tjener som ventiler. Denne hydrofobe 20 dækbane er af et folieagtigt materiale.For this purpose, the specification of U.S. Pat. No. 3,814,101 discloses the use of a hydrophobic tire web having a series of slots which slots serve as valves. This hydrophobic 20 tire web is of a foil-like material.
Hydrofobe uvævede materialer er blevet benyttet til ble-konstruktion, jf. US-patentskrift nr. 3.987.786, der benytter brugen af et overfladeaktivt middel i specielle områder på be-25 handlede materialer.Hydrophobic nonwoven materials have been used for diaper construction, cf. U.S. Patent No. 3,987,786, which utilizes the use of a surfactant in special areas on treated materials.
Fra US-patentskri ft nr. 3.838.692 kendes et hydrofobt materiale med hydrofile områder og egnet til bleer. De adskilte hydrofile områder opnås ved, at det overfladeaktive middel im-30 prægneres i hele toplagets tykkelse og gennemtrænger toplaget fra den ene overflade til den anden således, at man ikke kan få de gode egenskaber med hensyn til ti 1bagevædnings- eller -strømn i ngsfaktoren.US Patent No. 3,838,692 discloses a hydrophobic material having hydrophilic regions and suitable for diapers. The separated hydrophilic regions are obtained by impregnating the surfactant throughout the thickness of the top layer and penetrating the top layer from one surface to the other so as not to obtain the good properties with respect to backwetting or flow in the ng factor. .
35 Det er den foreliggende opfindelses formål at anvise et dæklag, der letter fluidumpassage fra ydersiden og ind til en bagved liggende pude og som samtidig reducerer ti 1bagevædning eller -strømning til et minimum.It is an object of the present invention to provide a cover layer that facilitates fluid passage from the outside to an underlying cushion and at the same time minimizes back wetting or flow.
DK 160074 BDK 160074 B
22
Dette formål tilgodeses ved, at det indledningsvist omtalte produkt er ejendommelig ved det i den kendetegnende del af krav 1 anførte. Ved at det overfladeaktive middel kun er anbragt på dækbanens ydre overflade og ikke strækker sig ind i 5 denne, sikres på enkel måde, at fluidum nemt kan strømme ind i en underliggende pude, men i stor udstrækning af det hydrofobe materiales indre overflade forhindres i at strømme tilbage.This object is fulfilled by the fact that the product mentioned in the introduction is peculiar to that of the characterizing part of claim 1. By placing the surfactant only on the outer surface of the tire web and not extending into it, it is simply ensured that fluid can readily flow into an underlying pad, but to a large extent preventing the inner surface of the hydrophobic material from flow back.
Det er væsentligt, at det overfladeaktive middel ikke gennem-trænger hele dækbanens materiale, men kun tjener til først at 10 styre fluidummet, således at dette trænger gennem det ikke- vævede hydrofobe materiale ind til en underliggende absorberende pude, og således at det endvidere begrænser tilbagestrømning fra puden.It is essential that the surfactant does not penetrate the entire tire web material, but only serves to first control the fluid so that it penetrates the nonwoven hydrophobic material into an underlying absorbent pad and further limits it. backflow from the pad.
15 Som anført i den kendetegnende del af krav 2 foretrækkes det, at det overfladeaktive middel kun påtrykkes dækbanens midterområde. Herved kan man udforme f.eks. en ble, så den er egnet til henholdsvis drenge eller piger. Som anført i den kendetegnende del af krav 3 foretrækkes det, at det overfladeaktive 20 middel er ikke-ionisk, hvorved man opnår en hurtig fluidum- gennemtrængning samtidig med, at man bevarer optimale tilbage-vædnings- og fluidumtilbageholdelseskarakteristika.As stated in the characterizing part of claim 2, it is preferred that the surfactant is applied only to the median region of the tire web. Hereby one can design e.g. a diaper, so it is suitable for boys or girls respectively. As stated in the characterizing part of claim 3, it is preferred that the surfactant 20 is nonionic, thereby achieving a rapid fluid penetration while retaining optimum recovery and fluid retention characteristics.

10 På tegningen, hvor de samme henvisningstal angår til hinanden svarende dele i de forskellige afbildninger, angiver henvisningstallet 10 i sin helhed en ble, der indbefatter en bundbane 12 af vanduigennemtrængelig plastisk foliemateriale (der kan være præget eller matteret), hvorpå der er monteret en 15 pude 14 formet af en absorberende kærne, der kan have et eller flere vatteringslag. Dækbanen 16 er fremstillet af uvævet hydrofobt materiale, såsom polypropylen-, polyamid- eller polyesterfibre. Bleen 10's dele er samlet på kendt måde. Dækbanen i sig selv er af kendt art og kan være spindebundet, være lagt 20 tørt eller vådt, og kan være bundet ad kemisk eller termisk vej.10 In the drawing, where the same reference numerals relate to similar parts in the various depictions, reference numeral 10 indicates in its entirety a diaper which includes a bottom web 12 of water-impervious plastic film material (which may be embossed or matted) on which a 15 pad 14 formed by an absorbent core which may have one or more padding layers. The cover web 16 is made of nonwoven hydrophobic material such as polypropylene, polyamide or polyester fibers. The parts of diaper 10 are assembled in known manner. The tire web itself is of a known kind and may be spunbonded, laid 20 dry or wet, and may be bonded by chemical or thermal means.
I overensstemmelse med den foreliggende opfindelses idé behandles dækbanen, såsom ved henvisningstallet 18, med 0,1 til 25 0,6 vægt% af et overfladeaktivt middel i stand til at ændre de hydrofobe egenskaber for materialet på dettes topoverflade.In accordance with the idea of the present invention, as in reference numeral 18, the tire web is treated with 0.1 to 25 0.6% by weight of a surfactant capable of altering the hydrophobic properties of the material on its top surface.
Det overfladeaktive middel er fortrinsvis et ikke-ionisk stof, og man foretrækker især et ethoxylat af (1) en Cj2 til c20 alkohol (f.eks. 5-20 mol af ethylenoxid), (2) en C6 til C10 30 alkylphenol (f.eks. 5-30 mol af ethylenoxid). Et foretrukkent ikke-ionisk stof er "Triton X-100" (10 ethylenoxidkondensat med octylphenol). Som vist i fig. 3, kan det sprøjtes eller overfladetrykkes som angivet ved henvisningstallet 20 i blot dækbanen 16's midterområder. Man kan også anvende kendte val-35 sebelægningsfremgangsmåder.The surfactant is preferably a non-ionic substance, and in particular an ethoxylate of (1) a C 2 to c 20 alcohol (e.g. 5-20 moles of ethylene oxide), (2) a C 6 to C 10 alkyl phenol (f eg 5-30 moles of ethylene oxide). A preferred non-ionic substance is "Triton X-100" (10 ethylene oxide condensate with octylphenol). As shown in FIG. 3, it can be sprayed or surface printed as indicated by reference numeral 20 in the center regions of the tire web 16 only. Known roller coating methods can also be used.
Som vist i fig. 4a kan det overfladeaktive middel påtrykkes i en linie som vist ved henvisningstallet 22. Alternativt kanAs shown in FIG. 4a, the surfactant may be applied in a line as shown by reference numeral 22. Alternatively, the
DK 160074BDK 160074B
4 det overfladeaktive middel påtrykkes pletvist som vist ved henvisningstallet 24 i fig. 4b i indbyrdes adskilte områder anbragt med mellemrum. I en foretrukken udførelsesform, som vist i fig. 5, er det overfladeaktive middel påtrykt i linier, 5 som vist ved henvisningstallet 26, anbragt med mellemrum i hver linie med de områder, der trykkes i hver linie, forskudt i forhold til hinanden.4, the surfactant is applied stainly as shown by reference numeral 24 in FIG. 4b in spaced apart spaces spaced apart. In a preferred embodiment, as shown in FIG. 5, the surfactant printed on lines 5, as shown by reference numeral 26, is spaced apart in each line with the regions printed in each line offset relative to each other.
En sårlig foretrukken liniebehandling er én, hvori linierne 10 22, i stedet for at være parallel med bleens sider, er arran geret diagonalt (under en vinkel på fra 30 til 60° med blekanten). I en anden hensigtsmæssig udførelsesform er linierne vist i fig. 4a drejet 90°.A particularly preferred line treatment is one in which the lines 10 22, rather than being parallel to the sides of the diaper, are arranged diagonally (at an angle of from 30 to 60 ° with the diaper edge). In another convenient embodiment, the lines shown in FIG. 4a is turned 90 °.
15 Ved brug forøges fluidumgennemtrængningsevnen ved hjælp af de med overfladeaktivt middel behandlede områder af det ikke-vævede hydrofobe materiale og tillader derved en hurtigere fluidumgennemtrængning. Der optræder imidlertid kun en. lille ændring i de ønskelige eller tilstræbte fluidumtiIbagevæd- 20 nings- eller -strømnings- og fluidumtilbageholdelseskarakteristika. I den foretrukne topoverfladebehandling trænger det overfladeaktive middel ikke gennem materialet, men tjener kun til fra først af at styre det fluide materiale til at trænge igennem det uvævede hydrofobe materiale, og dette begrænser 25 yderligere tilbagestrømning.In use, the fluid permeability is enhanced by the surfactant-treated areas of the nonwoven hydrophobic material, thereby allowing a faster fluid penetration. However, there is only one. little change in the desirable or desired fluid retention or flow and fluid retention characteristics. In the preferred top surface treatment, the surfactant does not penetrate the material, but only serves to first control the fluid material to penetrate the nonwoven hydrophobic material, which limits further backflow.
De behandlede dækbaner ifølge den foreliggende opfindelse har en gennemtrængningsfaktor på mindst 80 og en ti 1bagevædnings-eller strømningsfaktor på ikke større end 10. Disse faktorer 30 repræsenterer procent af fluidum, der passerer gennem banen i prøveperiodetiden og den procent "der væder eller strømmer tilbage" i den foreskrevne prøve. I prøvefremgangsmåden benyttes 30 cm3 fluidum. Hvis alt passerer gennem banen uden nogen "afrulning" (afstrømning) er gennemtrængningsfaktoren 35 100. Hvis halvdelen ruller (strømmer) af, er faktoren 50. På tilsvarende måde, hvis 15 cm3 af fluidet strømmer tilbage ved den foreskrevne fremgangsmåde, så er tiIbagevædningsfaktorenThe treated tire webs of the present invention have a permeation factor of at least 80 and a ten baking or flow factor of not greater than 10. These factors 30 represent percent of fluid passing through the web during the trial period and the percent "wetting or flowing back". in the prescribed sample. In the test method, 30 cm 3 of fluid is used. If everything passes through the web without any "roll-off", the penetration factor is 35 100. If half rolls (flows) off, the factor is 50. Similarly, if 15 cm 3 of the fluid flows back in the prescribed process, then the backwetting factor is
