Abstract

The nonwoven disposable tissues (11) are produced from a nonwoven web in stamped or cut outline shapes. The cut or stamped sections are compressed in a compressing mold (20) by a compression piston (22) working at a high pressure. The compressed tissue remains in a compact structure, and only opens out when wetted with a fluid. The nonwoven material is drawn from a supply roll. Where axially symmetrical tissues are to be produced, the material is folded along the center and moved to give only one symmetrical half to view. The tissue section is forced into the mold (20) by a piston (21), and compressed while dry. Or the material can be compressed while wet, to be dried during or after the compression stage. An Independent claim is included for a disposable tissue (11) in the form of a face mask, with openings cut out for the eyes, nose and mouth. Preferred Features: The nose opening can be interrupted by two bars.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung komprimierter Vliesstofftücher.The invention relates to a process for producing compressed nonwoven fabrics.

Vliesstofftücher sind als solches bekannt und werden beispielsweise als kosmetische Reinigungstücher vielfältig eingesetzt. Bei den bekannten Vliesstofftüchern ist nachteilig, daß diese bei der Bevorratung ein relativ großes Volumen einnehmen, was zu einem relativ großen Verpackungs- und Lagerhaltungsaufwand führt.Nonwoven fabrics are known as such and For example, they are used as cosmetic wipes used in many ways. In the known nonwoven fabric towels is disadvantageous that this in the storage a occupy a relatively large volume, resulting in a relative large packaging and storage costs leads.

Gattungsgemäße lösungen sind aus der JP 03 119 173.Generic solutions are known from JP 03 119 173.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, Vliesstofftücher zu schaffen, die bei der Bevorratung ein relativ geringes Volumen einnehmen, sowie ein Verfahren zu deren Herstellung anzugeben, das kostengünstig ausführbar ist.The present invention is therefore the The object of the invention is to provide nonwoven fabrics which are at the stocking occupy a relatively small volume, and to provide a method of making the same, which is inexpensive to carry out.

Die Aufgabe wird hinsichtlich des Verfahrens zur Herstellung der Vliesstofftücher durch die Merkmale des Anspruchs 1, gelöst.The task is in terms of the process for producing the nonwoven fabrics by the features of claim 1, solved.

Der Erfindung liegt die Erkenntnis zugrunde, daß durch Einbringen der Vilesstofftücher in eine Komprimierform und anschließendes Verdichten der Vliesstofftücher sich eine besonders hohe Packungsdichte erreichen läßt. Dabei erfolgt das Verdichten der Vliesstofftücher erfindungsgemäß unter einem derart hohen Kompressionsdruck, daß sich die Vliesstofftücher nicht von selbst, sondern erst nach einem Befeuchten mit einer Flüssigkeit wieder entfalten. Die Vliesstofftücher können daher in einer hohen Packungsdichte platzsparend verpackt und bevorratet werden. Erst unmittelbar vor der Benutzung der Vliesstofftücher werden diese durch ein Befeuchten mit einer Flüssigkeit wieder entfaltet. Durch das Befeuchten werden die Vliesstofftücher wieder dekomprimiert, so daß sie sich im wesentlichen von selbst entfalten oder sich zumindest ohne größere Schwierigkeiten entfalten lassen.The invention is based on the knowledge that by introducing the Vilesstofftücher in a Komprimierform and then compacting the nonwoven fabrics a particularly high packing density reach. The compacting of the nonwoven fabrics takes place According to the invention under such a high Compression that the nonwoven fabrics do not by itself, but only after a moistening with a Unfold the liquid again. The non-woven cloths can therefore save space in a high packing density packed and stored. Only immediately before using the nonwoven fabrics they are unfolded by moistening with a liquid again. By moistening the nonwoven fabrics are decompressed again, so that they are essentially by itself unfold or at least without cause greater difficulties.

Die Ansprüche 2 bis 5 betreffen vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens.Claims 2 to 5 relate to advantageous Further developments of the method according to the invention.

Der Vliesstoff wird entsprechend Anspruch 2 vorteilhaft von einer Vorratsrolle abgezogen und kann in einem Endlosverfahren bearbeitet werden. Zum Herstellen von axialsymmetrischen Vliesstofftüchem, beispielsweise Gesichtsmasken, ist es entsprechend Anspruch 3 vorteilhaft, den Vliesstoff mittig zu falten und die Vliesstofftücher mittels eines Ausbringzeugs auszubringen, das nur eine Symmetriehälfte des Vliesstofftuchs umfaßt. Auf diese Weise wird bei einer rationellen Fertigung eine hohe Symmetriegenauigkeit der Vliesstofftücher erreicht. Als Ausbringzeug eignet sich beispielsweise ein Stanzwerkzeug oder ein Schneidwerkzeug.The nonwoven fabric is according to claim 2 advantageously deducted from a supply roll and can be processed in a continuous process. For manufacturing of axially symmetric nonwoven fabrics, for example Face masks, it is according to claim 3 advantageous to fold the nonwoven fabric in the middle and to apply the non-woven cloths by means of a dispenser the only one half of symmetry of the nonwoven fabric includes. In this way, at a rational Manufacturing a high symmetry accuracy of nonwoven fabrics reached. As a Ausbringzeug is suitable, for example a punch or a cutting tool.

Die Vliesstofftücher werden entsprechend Anspruch 4 durch einen Einbringkolben in die Komprimierform eingebracht und entsprechend Anspruch 4 in dem trockenen Zustand verdichtet. Alternativ ist es entsprechend Anspruch 5 auch möglich, die Vliesstofftücher vor dem Verdichten zu befeuchten, im befeuchteten Zustand zu verdichten und während des Verdichtens oder im Anschluß daran zu trocknen. Der Kompressionsdruck kann dann geringer sein.The nonwoven fabrics are according to claim 4 by an introduction piston in introduced the Komprimierform and according to the claim 4 compressed in the dry state. alternative It is also possible according to claim 5, the Nonwoven cloths to be moistened before compacting, in to moisten the moistened state and during the Compacting or subsequently drying. Of the Compression pressure can then be lower.

Das Vliesstofftuch hat die Form einer Gesichtsmaske. Dabei sind zwei Augenöffnungen und eine Mundöffnung vorgesehen, die aus dem Vliesstofftuch herausgetrennt sind. Ferner kann eine Nasenperforation vorgesehen sein, die einen Naseniappenvon dem Hauptteil des Vliesstofftuchs trennt, wobei der Nasenlappen beim Tragen der Gesichtsmaske auf der Nase so aufliegt, daß die Nasenöffnungen freiliegen. Dabei ist es vorteilhaft, die Nasenperforation durch zwei Stege zu unterbrechen, die bei der Benutzung ohne weiteres aufgetrennt werden können. Es hat sich gezeigt, daß die Verarbeitung des Vliesstofftuchs insbesondere bei dem Verfahrensschritt des Verdichtens durch diese Stege erleichtert ist.The non-woven fabric has the shape of a face mask. There are two eye openings and one Mouth opening provided from the nonwoven cloth are separated out. Furthermore, can a nose perforation be provided, the one Nose flap of the main part of the nonwoven fabric separates, taking the nose lobe while wearing the face mask rests on the nose so that the nostrils exposed. That's it advantageous, the nasal perforation by two To break webs, which in use easily can be separated. It has shown, that the processing of the nonwoven fabric cloth in particular in the step of compacting through them Webs is relieved.

Das Vliesstofftuch besteht vorzugsweise aus einem faserigen Material, beispielsweise Viskose und/oder Polypropylen und/oder Polyester und/oder Zellstoff. Entsprechend einem bevorzugten Ausführungsbeispiel besteht das Vliesstofftuch zu 100% aus Viskose.The nonwoven fabric consists preferably of a fibrous material, For example, viscose and / or polypropylene and / or Polyester and / or pulp. According to one preferred embodiment is the nonwoven fabric sheet 100% viscose.

Das erfindungsgemäße Verfahren wird nachfolgend unter Bezugnahme auf die Fig. 1, 2A und 2B beschrieben.The method according to the invention will be described below with reference to Figs. 1, 2A and 2B described.

Wie aus Fig. 1 erkennbar, wird der Vliesstoff 1 zunächst von einer drehbar aufgehängten Vorratsrolle 2 abgezogen und einer Falteinrichtung 3 zugeführt. Bei dem Vliesstoff handelt es sich um ein faseriges Material. Neben Viskose sind auch Polypropylen, Polyester und Zellstoff besonders geeignet, wobei die erfindungsgemäßen Vliesstofftücher in einem besonders bevorzugten Ausführungsbeispiel aus 100 % Viskose bestehen. Geeignet ist jedoch grundsätzlich jedes faserige, zumindest im geringen Umfang saugfähige Material.As can be seen from FIG. 1, the nonwoven fabric 1 initially by a rotatably hung supply roll 2 withdrawn and fed to a folding device 3. at The nonwoven fabric is a fibrous material. Besides viscose are also polypropylene, polyester and Pulp particularly suitable, wherein the inventive Nonwoven fabrics in a particularly preferred Embodiment consist of 100% viscose. In principle, however, any fibrous material is suitable, at least to a small extent absorbent material.

An der Falteinrichtung 3 wird die Vliesstoffbahn 10 im Ausführungsbeispiel mittig gefaltet, was durch den Pfeil 4 veranschaulicht ist. Dazu dient eine Faltschulter 5, die selbstverständlich auch vertikal angeordnet sein kann. Die Vliesstoffbahn 10 kann auch mehrfach gefaltet werden, um eine mehrlagige Weiterverarbeitung zu ermöglichen. Die Stoffbahnen werden durch Führungsrollen 6 und 7 geglättet und zueinander fixiert, bevorsie einer Stanzeinrichtung 8 zugeführtwerden.At the folding device 3, the nonwoven web 10 folded centrally in the embodiment, which is illustrated by the arrow 4. This serves a Faltschulter 5, which of course also arranged vertically can be. The nonwoven web 10 may also be folded several times to a multi-layer finishing to enable. The fabric will be smoothed by guide rollers 6 and 7 and each other fixed before being fed to a punching device 8.

Die Stanzeinrichtung 8 umfaßt ein Stanzwerkzeug 9, das aus der im Ausführungsbeispiel zweilagigen Vliesstoffbahn 10 die Vliesstofftücher 11 in der gewünschten Form herausstanzt. Im dargestellten Ausführungsbeispiel handelt es sich bei den Vllesstofftüchern 11 um eine Gesichtsmaske, die in Fig. 1 zur besseren Veranschaulichung im entfalteten Zustand dargestellt ist, wenngleich sie nach dem Ausstanzen um ihre Symmetrieachse einfach gefaltet vorliegt. Im Ausführungsbeispiel umfaßt das Stanzwerkzeug 9 nur eine Symmetriehälfte des auszustanzenden Vliesstofftuchs 11, wobei die Symmetrieachse 12 des Vliesstofftuchs 11 bzw. der Gesichtsmaske mit der Faltkante 13 der zweilagigen Vliesstoffbahn zusammenfällt. Dies hat den Vorteil, daß das Ausstanzen mit einer hohen Fertigungseffektivität erfolgt und zugleich das Vliesstofftuch 11 vor dem noch zu beschreibenden Verdichten bereits einfach vorgefaltet ist. Alternativ könnten die Vliesstofftücher 11 bzw. die Gesichtsmasken jedoch auch ungefaltet aus dem Vliesstoff bzw. der mehrlagigen Vliesstoffbahn 10 ausgestanzt werden. Bei einer mehrlagigen Vliesstoffbahn 10 hätte dies den Vorteil, daß mit jedem Stanzvorgang mehrere Vliesstofftücher bzw. Gesichtsmasken 11 gestanzt werden, was ebenfalls zu einer hohen Fertigungseffektivität führt.The punching device 8 comprises a punching tool 9, the two-layered in the embodiment Nonwoven web 10, the nonwoven fabric sheets 11 in the desired Punch out shape. In the illustrated embodiment these are the reading cloths 11 to a face mask, in Fig. 1 for the better Illustrated in the unfolded state is, although they are after punching out theirs Symmetry axis is simply folded. In the embodiment the punching tool 9 comprises only one Symmetrie half of auszustanzenden nonwoven fabric 11, wherein the axis of symmetry 12 of the nonwoven fabric 11 and the face mask with the folding edge 13 of the two-ply nonwoven web coincides. This has the Advantage that the punching with a high production efficiency takes place and at the same time the nonwoven fabric 11 already before the compression to be described just prefolded. Alternatively, the nonwoven fabrics could 11 or the face masks but also unfolded from the nonwoven fabric or the multilayer nonwoven web 10 are punched out. In a multilayered Nonwoven web 10 would have the advantage that with each Punching several nonwoven cloths or face masks 11 are punched, which also to a high manufacturing efficiency leads.

Die Vliesstofflücher 11 bzw. im Ausführungsbeispiel die Gesichtsmasken können beispielsweise durch ein Förderband 14 nach dem Stanzen abgefördert werden.The nonwoven cloths 11 or in the embodiment For example, the face masks can conveyed away by a conveyor belt 14 after punching become.

Anstatt die Vliesstofftücher 11 aus der Vliesstoffbahn 10 durch Stanzen auszubringen, kann beispielsweise auch ein Ultraschallschneiden, ein thermisches Schneiden mit einem Hitzdraht oder dergleichen zum Einsatz kommen.Instead of the nonwoven fabric sheets 11 from the nonwoven web 10 by punching, for example also an ultrasonic cutting, a thermal Cutting with a hot wire or the like be used.

Die Fig. 2A und 2B veranschaulichen den Verfahrensschritt des Verdichtens der Vliesstofftücher 11. Durch den in Fig. 2A dargestellten Verfahrensschritt werden die Vliesstofftücher 11 in eine Komprimierform 20 eingebracht, mittels eines Einbringkolbens 21, der beim Einbringen in die Komprimierform 20 das Vliesstofftuch 11 mitnimmt und in die Komprimierform 20 einbringt. Vorzugsweise befindet sich das Vliesstofftuch 11 entgegen der Darstellung in Fig. 2A beim Einbringen in die Komprimierform 20 in einem um seine Symmetrieachse 12 einfach gefalteten Faltzustand, was das Einbringen in die Komprimierform 20 erleichtert. Das Vliesstofftuch kann auch vor dem Einbringen in die Komprimierform 20 mehrfach definiert gefaltet werden und in einer anderen definierten Faltlage in die Komprimierform 20 eingebracht werden, wenn dies im Einzelfall vorteilhaft ist. Beim Einbringen mittels eines Einbringkolbens 21 ist der Durchmesser des Einbringkolbens 21 gegenüber dem Durchmesser der Komprimierform deutlich geringer zu bemessen, um ein Verklemmen des Vliesstoffluchs 11 zwischen der Wandung der Komprimierform 20 und dem Einbringkolben 21 zu vermeiden. Beim Einbringen entsteht eine zufällige Vielfachfaltung des Vliesstofftuchs 11.FIGS. 2A and 2B illustrate the method step the compacting of the nonwoven fabric sheets 11. By the process step shown in Fig. 2A The nonwoven fabric sheets 11 are in a Komprimierform 20 introduced, by means of an insertion piston 21, the Inserting into the compression mold 20 the nonwoven fabric sheet 11 entrains and brings in the Komprimierform 20. Preferably, the nonwoven fabric 11 is opposite the representation in Fig. 2A when introduced into the Compression mold 20 in one around its axis of symmetry 12 simply folded folding state, what the introduction facilitated in the compression mold 20. The nonwoven cloth may also be prior to insertion into the compression mold 20 can be folded multiple times and in another defined folding layer introduced into the compression mold 20 if this is advantageous in individual cases. When introducing by means of a Einbringkolbens 21 is the diameter the introduction piston 21 with respect to the diameter the compression shape to be significantly smaller, to a jamming of the nonwoven fabric 11 between the wall of the compression mold 20 and the To avoid introducing piston 21. When introducing arises a random multiple folding of the nonwoven cloth 11th

Bei dem in Fig. 2B schematisch dargestellten Verfahrensschritt erfolgt das Verdichten des sich in der Komprimierform 20 befindlichen Vliesstofftuchs 11. Dabei wird ein Komprimierkolben 22 in die Komprimierform 20 eingebracht und mit einem hohen Kompressionsdruck beaufschlagt. Vorteilhaft sind in der Komprimierform 20 oder in dem Komprimierkolben 22 eine oder mehrere Bohrungen zum Entweichen der eingeschlossenen Luft vorgesehen. Erfindungsgemäß erfolgt das Verdichten der Vliesstofftücher 11 unter einem derart hohen Kompressionsdruck bei einer bestimmten vorgegebenen Temperatur, daß sich die Vliesstofftücher 11 nicht von selbst, sondern erst nach einem Befeuchten mit einer Flüssigkeit wieder entfalten können. Wie Versuche der Anmelderin gezeigt haben, ist ein Kompressionsdruck von mehr als 20 bar, vorzugsweise mehr als 50 bar, erforderlich, wenn die Vliesstofftücher aus 100 % Viskose bestehen. Die Fasern des Vliesstoffes sind nach dieser Kompression dann soweit miteinander vernetzt, daß sich die Vliesstofftücher im trockenen Zustand nicht wieder von selbst entfalten können.In the in Fig. 2B schematically illustrated Process step, the compression takes place in the Komprimierform 20 located nonwoven fabric 11. In doing so a compression piston 22 becomes the compression mold 20 introduced and with a high compression pressure applied. Are advantageous in the Komprimierform 20 or in the compression piston 22 one or several holes to escape the trapped Air provided. According to the invention, this is done Compacting the nonwoven fabric sheets 11 under such a high compression pressure at a given preset Temperature that the nonwoven fabric towels 11 not by itself, but only after a moistening can unfold with a liquid again. Like experiments Applicants have shown is a compression pressure of more than 20 bar, preferably more than 50 bar, required if the nonwoven fabrics from 100 % Viscose exist. The fibers of the nonwoven fabric are then networked with each other after this compression, that the nonwoven fabrics in the dry state can not unfold again by itself.

Versuche haben gezeigt, daß eine Verdichtung im trockenen Zustand der Vliesstofftücher 11 am geeignetsten ist, wenn auch der benötigte Kompressionsdruck relativ hoch ist. Um den Kompressionsdruck zu vermindern, können die Vliesstofftücher 11 auch in einem angefeuchteten Zustand verdichtet und gleichzeitig oder anschließend getrocknet werden.Experiments have shown that a compression in the dry state of the nonwoven fabrics 11 am most suitable, albeit the required compression pressure is relatively high. To the compression pressure To reduce the nonwoven fabrics 11 may also in a moistened state compressed and simultaneously or subsequently dried.

Im in den Fig. 2A und 2B dargestellten Ausführungsbeispiel weist die Komprimierform 20 einen runden Querschnitt auf, so daß die Vliesstofftücher 11 zu einer tablettenförmigen Form verdichtet werden. In Fig. 2C ist ein Vliesstofftuch 11 in einem komprimierten, tablettenförmigen Zustand dargestellt. Diese tablettenförmigen Vliesstofftücher sind beispielsweise in Tablettenröhrchen verpackbar. An dem Komprimierkolben 22 kann unterseitig eine Aufschrift vorgesehen sein, die in die komprimierten Vliesstofftücher 11 eine Aufschrift 23, beispielsweise eine Marke oder einen Verwendungshinweis, einprägt. Grundsätzlich ist es auch möglich, die Vliesstofftücher 11 in jede beliebige andere Form zu verdichten.In the embodiment shown in Figs. 2A and 2B the compression mold 20 has a round Cross-section, so that the nonwoven fabric towels 11 to be compressed a tablet-like shape. In Fig. 2C is a nonwoven fabric sheet 11 in a compressed, tablet-shaped State shown. This tablet-shaped Nonwoven fabrics are for example in tablet tubes packable. On the compression piston 22 On the underside an inscription may be provided, which in the compressed nonwoven fabric sheets 11 an inscription 23, for example, a trademark or a note of use, impresses. Basically, it is also possible to Nonwoven cloths 11 in any other form to compress.

Fig. 3 zeigt in einer vergrößerten Darstellung ein Ausführungsbeispiel eines entfalteten Vliesstofftuchs 11 in Form einer Gesichtsmaske. Durch die Stanzeinrichtung 8 sind aus derdie Form eines menschlichen Gesichts aufweisenden Gesichtsmaske zwei Augenöffnungen 24 und eine Mundöffnung 25 herausgestanzt. Ferner ist eine Nasenperforation 26 gestanzt, die einen Nasenlappen 27 von dem Hauptteil 28 der Gesichtsmaske trennt. Der Nasenlappen 27 ist über eine Verbindung 29 und zwei Stege 30 mit dem Hauptteil 28 der Gesichtsmaske verbunden. Die Stege 30 dienen dazu, die Weiterverarbeitung nach dem Stanzen, insbesondere das Einbringen in die Komprimierform 20 zu erleichtem. Die Stege 30 können nach dem Entfalten der Gesichtsmaske im feuchten Zustand ohne weiteres durchtrenntwerden, so daß bei der Anwendung der Gesichtsmaske der Nasenlappen 26 auf der Nase aufliegt und die Nasenöffnungen freigibt. Die Augenöffnungen 24, Mundöffnung 25 und die Nasenperforation 26 können auch mit einem Schneidwerkzeug erstellt werden.Fig. 3 shows in an enlarged view an embodiment of a unfolded nonwoven fabric 11 in the form of a face mask. By the punching device 8 are of the form of a human Face mask with two eye openings 24 and a mouth opening 25 punched out. Further, a nose perforation 26 is punched, the one Nose tabs 27 of the main part 28 of the face mask separates. The nasal flap 27 is connected 29 and two webs 30 with the main part 28 of the Face mask connected. The webs 30 serve to further processing after punching, in particular the introduction into the compression mold 20 to facilitate. The webs 30 may after unfolding the face mask be severed in the wet state without further ado, so that when using the face mask the nose flap 26 rests on the nose and the nostrils releases. The eye openings 24, Mouth opening 25 and the nose perforation 26 can also be created with a cutting tool.

Das Entfalten der erfindungsgemäß hergestellten Vliesstofftücher 11 kann beispielsweise mittels Wasser, jedoch auch mittels jeder anderen Flüssigkeit oder pharmazeutischen oder kosmetischen Lösung erfolgen.The unfolding of the inventively prepared Nonwoven fabrics 11 may be, for example, by means of water, but also by means of any other liquid or pharmaceutical or cosmetic solution.

Das erfindungsgemäße Verfahren eignet sich auch zum Herstellen von komprimierten Vliesstofftüchern in anderer Form, aus anderen Materialien und für andere Anwendungszwecke.The inventive method is also suitable for manufacturing of compressed nonwoven fabrics in others Shape, of other materials and for other purposes.
