Abstract

PCT No. PCT/EP94/02902 Sec. 371 Date May 9, 1996 Sec. 102(e) Date May 9, 1996 PCT Filed Sep. 1, 1994 PCT Pub. No. WO95/07047 PCT Pub. Date Mar. 16, 1995A floor-cleaning mop head includes an oblong textile base fabric with, attached to the top at both ends, slide-in pockets for the head-holder and, attached underneath, material designed to collect moisture and dirt in the form of hair tufts, fringes, loops, foam-rubber strips, and so forth. The oblong base fabric consists, at least in the zone of the slide-in pockets, of a material which is more highly heat-shrinking than the textile material of which the pockets are made, in order to ensure that the pockets on top of mop remain open even after repeated washing of the mop head, without effecting other useful characteristics of the mop.

Description

Die Erfindung betrifft einen Wischbezug für die Reinigung von Fußböden mit einem textilen Trägergebilde in länglicher Form mit oberseitig an beiden Enden aufgebrachten Haltereinschubtaschen und unterseitig angebrachtem Material zur Aufnahme von Schmutz und Feuchtigkeit in Form von Zotteln, Fransen, Schlingen, Schwammtuchstreifen oder dgl.The invention relates to a mop cover for cleaning floors with a textile support structure in an elongated form with holder insert pockets attached to both ends at the top and material on the underside for absorbing dirt and moisture in the form of shag, fringes, loops, sponge cloth strips or the like.

Solche Wischbezüge werden bei der Fußbodenreinigung verwendet, wozu die Wischbezüge auf Halter aufgezogen werden. Dabei werden die Enden der Halter in die Haltereinschubtaschen eingefügt. Die Halter weisen einen Stiel auf, so daß die Halter mit aufgezogenem Wischbezug bequem über die zu reinigenden Fußböden geführt werden können.Such mop covers are used for floor cleaning, for which purpose the mop covers are mounted on the holder. The ends of the holders are inserted into the holder insert pockets. The holders have a handle, so that the holder can be easily guided over the floor to be cleaned with the mop cover open.

Ein gattungsgemäßer Wischbezug, bei welchem die Haltereinschubtaschen aus textilem Flächengebilde gebildet sein können, ist aus der DE-PS 38 09 279 bekannt. Bei einem derartigen Wischbezug kann die Einführung des Halters in die Haltereinschubtaschen aber nur bei geöffneten bzw. offen stehenden Taschen erfolgen. Da die Wischbezüge bei der Benutzung aber häufiger zur Entwässerung Pressen zugeführt werden und in regelmäßigen Abständen auch in Waschmaschinen gewaschen und gereinigt werden, kommt es vor, daß die Taschen nicht offen stehen, sondern auf dem textilen Trägergebilde aufliegen. Um den Halter einführen zu können, müssen die Taschen dann zunächst von Hand aufgerichtet werden.A generic mop cover, in which the holder insert pockets can be formed from textile fabrics, is known from DE-PS 38 09 279. With such a mop cover, the holder can only be inserted into the holder insertion pockets when the pockets are open or open. However, since the mop covers are often used for dewatering presses and are also washed and cleaned in washing machines at regular intervals, it happens that the pockets do not stand open, but rest on the textile support structure. To be able to insert the holder, the bags must first be erected by hand.

Um hier Abhilfe zu schaffen, sind Wischbezüge bekannt, die im Bereich der Taschenöffnungen Verstärkungen in Form von eingezogenen steifen Plastikstreifen oder ähnliche Stege aufweisen. Diese sind in den Haltereinschubtaschen eingenäht. Solche Verstärkungen weisen aber eine Reihe von Nachteilen auf. Zunächst einmal verursachen diese steifen Stege beim Auspressen der Wischbezüge in Pressen Probleme. Die Wischbezüge klemmen häufig zwischen den Pressrollen der Pressen ein. Auch wird bei Verstärkungsstreifen aus Plastik oder Kunststoff häufig eine Zerstörung der Verstärkungen festgestellt, so daß die Funktion des Offenhaltens der Taschenöffnungen anschließend nicht mehr gegeben ist. Des weiteren weisen die bekannten Lösungen Nachteile bei der Reinigung, also beim Waschen der Wischbezüge auf. Die versteiften Bereiche behindern den Walkprozeß beim Waschen der Wischbezüge in Waschmaschinen. Außerdem scheuern die steifen Stege und Taschen beim Waschprozeß auf dem Trägergebilde und führen so zu einer frühzeitigen Zerstörung des Wischbezuges. Auch wird das Gewicht der Waschgutmenge durch die Versteifungen erhöht, da die Haltereinschubtaschen nunmehr schwerer sind.To remedy this, mop covers are known which have reinforcements in the form of retracted rigid plastic strips or similar webs in the area of the pocket openings. These are sewn into the holder insertion pockets. However, such reinforcements have a number of disadvantages. First of all, these stiff webs cause problems when pressing out the mop covers in presses. The mop covers often get caught between the press rolls of the presses. In the case of reinforcement strips made of plastic or plastic, destruction of the reinforcements is often found, so that the function of keeping the pocket openings open is no longer provided. Furthermore, the known solutions have disadvantages in cleaning, that is to say when washing the mop covers. The stiffened areas hinder the flexing process when washing the mop covers in washing machines. In addition, the rigid webs and pockets rub against the support structure during the washing process and thus lead to premature destruction of the mop cover. The weight of the amount of laundry is increased by the stiffeners, since the holder insertion pockets are now heavier.

Es ist auch ein gattungsgemäßer Wischbezug der Anmelderin bekannt geworden (DE-PS 40 25 646), bei welchem die Haltereinschubtaschen im Bereich der Taschenöffnung Streifen aus wasseraufnahme- und quellfähigem Material aufweisen. Bei einem solchen Wischbezug kommt vor der ersten Benutzung der zunächst trockene, aus wasseraufnahme- und/oder quellfähigem Material bestehende Streifen mit Flüssigkeit in Berührung und saugt diese auf, wodurch sich das Volumen der Streifen vergrößert bzw. diese sich ausdehnen. Hierdurch wird ein selbsttätiges Öffnen bzw. das Offenhalten der Haltereinschubtaschen bewirkt, wobei die wasseraufnahme- und/oder quellfähigen Streifen elastisch bleiben und somit die Nachteile der vorbeschriebenen weiteren bekannten Lösungen nicht aufweisen.There has also become known a generic mop cover from the applicant (DE-PS 40 25 646), in which the holder insert pockets have strips of water-absorbent and swellable material in the region of the pocket opening. With such a mop cover, the initially dry strip, which consists of water-absorbing and / or swellable material, comes into contact with and absorbs liquid, which increases the volume of the strips or expands them. This results in an automatic opening or keeping the holder insert pockets open, the water-absorbing and / or swellable strips remaining elastic and thus not having the disadvantages of the other known solutions described above.

Es hat sich jedoch herausgestellt, daß bei einem solchen Wischbezug nach mehrmaliger Wäsche ein selbsttätiges Offenhalten der Haltereinschubtaschen doch nicht ohne weiteres gewährleistet ist, da beim Aufnähen der mit den betreffenden Streifen ausgerüsteten Taschen auf das Trägergebilde es nur möglich ist, die Taschen geringfügig erhaben anzuordnen. Dadurch ist aber die jeweilige Taschenöffnung für den Halter nahezu paßgenau. Da beim Waschen mit Waschtemperaturen von etwa 60°C das Taschen-/Trägergebildegewebe schrumpft, hat es sich herausgestellt, daß es dann nur noch schwer möglich ist, den Halter noch in die Taschen einzuführen.It has been found, however, that with such a mop cover after repeated washing, an automatic keeping of the holder insert pockets is not guaranteed, since when the pockets equipped with the strips in question are sewn onto the carrier structure, it is only possible to arrange the pockets slightly raised. As a result, the respective pocket opening for the holder is almost a perfect fit. Since the pocket / carrier fabric shrinks when washing at washing temperatures of about 60 ° C., it has been found that it then only it is difficult to insert the holder into the pockets.

Aufgabe der Erfindung ist deshalb die Schaffung einer Lösung, mit der ein Offenhalten der Taschen auch nach mehrmaliger Wäsche des Wischbezuges zu bewirken ist, ohne die weiteren Gebrauchseigenschaften eines solchen Wischbezuges zu beeinträchtigen.The object of the invention is therefore to provide a solution with which the pockets can be kept open even after the mop cover has been washed several times without impairing the further properties of use of such a mop cover.

Mit einem Wischbezug der eingangs bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß das längliche Trägergebilde wenigstens im Bereich der Haltereinschubtaschen aus einem gegenüber dem Textilmaterial der Haltereinschubtaschen stärker wärmeschrumpfenden Material besteht.This object is achieved according to the invention with a mop cover of the type mentioned at the outset in that the elongate support structure, at least in the region of the holder insert pockets, consists of a material which shrinks more than the textile material of the holder insert pockets.

Durch diese Ausgestaltung des erfindungsgemäßen Wischbezuges wird das selbsttätige Offenhalten der Haltereinschubtaschen durch mehrmalige Wäsche des Wischbezuges noch verbessert. Durch das Waschen schrumpft nämlich das Gewebe des Trägergebildes stärker als das Gewebe der Taschen, so daß die Taschen sich zwangsweise zusätzlich wölben müssen, d.h. durch das unterschiedliche Schrumpfverhalten öffnet sich die Tasche automatisch und zusätzlich, wodurch die Haltereinführung deutlich begünstigt wird. Gleichzeitig ist auch die Herstellung des Wischbezuges vereinfacht, da keine zusätzlichen Elemente aus Plastikstreifen oder aus wasseraufnahme- und/oder quellfähigen Streifen erforderlich sind, die mit den Taschen vernäht werden müssen. Da sowohl das Gewebe der Taschen als auch des Trägergebildes elastisch ist, wird der Walkprozeß in Waschmaschinen nicht behindert und die Bezüge werden auch in Pressen anschließend nicht deformiert. Außerdem ist das Mischgewebe des Trägergebildes saugfähig, so daß auch das Trägergebilde am Reinigungsprozeß teilnimmt.This configuration of the mop cover according to the invention further improves the automatic holding open of the holder insert pockets by washing the mop cover several times. Because of the washing, the fabric of the carrier structure shrinks more than the fabric of the pockets, so that the pockets must inevitably bulge additionally, ie the pocket automatically opens due to the different shrinking behavior, as a result of which the insertion of the holder is significantly favored. At the same time, the manufacture of the mop cover is simplified because there are no additional ones Elements made of plastic strips or water-absorbent and / or swellable strips are required, which must be sewn to the pockets. Since both the fabric of the pockets and the carrier structure are elastic, the flexing process in washing machines is not hindered and the covers are not subsequently deformed even in presses. In addition, the mixed fabric of the support structure is absorbent, so that the support structure also takes part in the cleaning process.

In besonders vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, daß das Trägergebilde aus einem Baumwoll-Kunststoff-Mischgewebe und die Haltereinschubttaschen aus einem reinen Kunststoffgewebe bestehen. Das Mischgewebe des Trägergebildes ist dabei so zu wählen, daß ein ausreichend unterschiedliches Schrumpfverhalten zwischen dem Trägergebildegewebe und dem Taschengewebe gewährleistet ist.In a particularly advantageous embodiment of the invention, it is provided that the carrier structure consists of a cotton-plastic mixed fabric and the holder insert pockets consist of a pure plastic fabric. The mixed fabric of the carrier structure is to be selected so that a sufficiently different shrinkage behavior between the carrier structure fabric and the pocket fabric is ensured.

Vorzugsweise besteht das Trägergebilde aus einem Mischgewebe aus Baumwolle/Polyester, Baumwolle/Polyamid oder auch aus Baumwolle/Polypropylen.The carrier structure preferably consists of a blended fabric of cotton / polyester, cotton / polyamide or also of cotton / polypropylene.

Das Kunststoffgewebe der Haltereinschubtaschen besteht vorzugsweise aus Polyester, wobei grundsätzlich auch andere Kunststoffgewebe einsetzbar sind. Polyestertaschen sind allerdings besonders strapazierfähig und reinigungsinaktiv.The plastic fabric of the holder insert pockets is preferably made of polyester, although in principle other plastic fabrics can also be used. However, polyester bags are particularly hard-wearing and inactive for cleaning.

Besteht beispielsweise das Mischgewebe des Trägergebildes aus 65 % Polyester und 35 % Baumwolle und das Kunststoffgewebe der Taschen aus Polyester, so hat sich herausgestellt, daß nach fünfmaliger 60°-Wäsche eines erfindungsgemäßen Wischbezuges das Trägergebilde um 4 % schrumpft, während die Taschen nur um 1 % schrumpfen, so daß sich der gewünschte Offenhalteeffekt durch Wölbung der Taschen einstellt.If, for example, the mixed fabric of the carrier structure is made of 65% polyester and 35% cotton and the plastic fabric of the pockets is made of polyester, it has been found that after washing the mop cover according to the invention five times at 60 °, the carrier structure shrinks by 4%, while the pockets only shrink by 1 % shrink so that the desired hold-open effect arises due to the curvature of the pockets.

Die Erfindung ist nachstehend anhand der Zeichnung anhand eines Ausführungsbeispiels anhand der einzigen Zeichnung beispielsweise näher erläutert.The invention is explained below with reference to the drawing using an exemplary embodiment using the single drawing, for example.

Diese zeigt einen erfindungsgemäßen Wischbezug in perspektivischer Darstellung.This shows a mop cover according to the invention in a perspective view.

Ein erfindungsgemäßer Wischbezug in Form eines Flachwischmops ist in der Zeichnung allgemein mit 1 bezeichnet. Dieser Wischbezug 1 weist ein textiles Trägergebilde 2 in länglicher Form auf, auf welches auf der Oberseite längsendseitig jeweils eine Haltereinschubtasche 3 aufgenäht ist, welche jeweils zur endseitigen Aufnahme eines Halters 4 dient. Dieser Halter 4 ist in bekannter Weise über ein Gelenk 5 mit einem Stiel 6 verbunden.A mop cover according to the invention in the form of a flat mop is generally designated 1 in the drawing. This mop cover 1 has a textile support structure 2 in an elongated shape, onto which a holder insertion pocket 3 is sewn on the top on the longitudinal end side, which is used to hold a holder 4 at the end. This holder 4 is connected in a known manner via a joint 5 to a handle 6.

Während die Haltereinschubtaschen 3 aus einem reinen Kunststoff-Gewebe, beispielsweise Polyester bestehen, besteht das Trägergebilde 2 aus einem Baumwoll-Kunststoff-Mischgewebe, welches gegenüber dem Kunststoffgewebe der Haltereinschubtaschen 3 bei Wärmebeaufschlagung, insbesondere in einer Waschmaschine, stärker schrumpft.While the holder insertion pockets 3 consist of a pure plastic fabric, for example polyester, the carrier structure 2 consists of a cotton-plastic mixed fabric, which shrinks more than the plastic fabric of the holder insertion pockets 3 when exposed to heat, in particular in a washing machine.

An der Unterseite des textilen Flächengebildes 2, d.h. auf der reinigungsaktiven Seite, weist das textile Trägergebilde 2 eine Vielzahl von nebeneinander angeordneten Streifen oder Fransen 7 aus Schwammtuchmaterial oder dgl. auf, wobei der äußere Rand des Trägergebildes 2 mit einem umlaufenden Einfaßband 8 versehen ist.On the underside of the fabric 2, i.e. on the active cleaning side, the textile support structure 2 has a multiplicity of strips or fringes 7 arranged next to one another made of sponge cloth material or the like, the outer edge of the support structure 2 being provided with a circumferential binding tape 8.

Die Einschuböffnungen der Haltereinschubtaschen 3 sind mit 9 bezeichnet, vorzugsweise weisen die Haltereinschubtaschen 3 jeweils am anderen Ende Wasseraustrittsöffnungen 10 auf.The insertion openings of the holder insertion pockets 3 are designated by 9, preferably the holder insertion pockets 3 each have water outlet openings 10 at the other end.

In besonders bevorzugter Ausführung des erfindungsgemäßen Wischbezuges 1 besteht das textile Trägergebilde 2 aus einem Mischgewebe aus 65 % Polyester und 35 % Baumwolle, während die aufgenähten Haltereinschubtaschen 3 aus reinem Polyestergewebe bestehen.In a particularly preferred embodiment of the mop cover 1 according to the invention, the textile carrier structure 2 consists of a mixed fabric of 65% polyester and 35% cotton, while the sewn-on holder insertion pockets 3 consist of pure polyester fabric.

Durch diese Kombination unterschiedlicher Materialien für die Textilgewebe der Taschen 3 und des Trägergebildes 2 ergibt sich beim Waschen des Wischbezuges 1 ein unterschiedlicher Schrumpf, wobei sich beispielsweise nach fünfmaliger 60°-Wäsche herausgestellt hat, daß das Trägergebilde 2 um 4 % schrumpft, während die Haltereinschubtaschen 3 jeweils nur um 1 % schrumpfen. Durch diese unterschiedliche Schrumpfung erfolgt zwangsweise eine Wölbung der Taschen 3, so daß die Taschen 3 automatisch offengehalten werden und dementsprechend die Tascheneinschuböffnungen 9 zum Einsetzen des Halters 4 frei zugänglich sind.This combination of different materials for the textile fabrics of the pockets 3 and the support structure 2 results a different shrinkage occurs when washing the mop cover 1, it being found, for example, after five 60 ° washes, that the carrier structure 2 shrinks by 4%, while the holder insert pockets 3 each shrink only by 1%. Due to this different shrinkage, the pockets 3 are forcibly arched, so that the pockets 3 are automatically kept open and, accordingly, the pocket insertion openings 9 are freely accessible for inserting the holder 4.

Natürlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Grundgedanken zu verlassen. So können selbstverständlich auch andere Materialien für die Taschen 3 und das Trägergebilde 2 eingesetzt werden, wesentlich ist jedoch, daß für das Trägergebilde 2 ein Textilgewebe gewählt wird, das bei Wärmebeaufschlagung beim Waschen stärker schrumpft als das Gewebe der Taschen 3.Of course, the invention is not limited to the illustrated embodiment. Further configurations are possible without leaving the basic idea. Of course, other materials can also be used for the pockets 3 and the carrier structure 2, but it is essential that a textile fabric is selected for the carrier structure 2 that shrinks more when exposed to heat during washing than the tissue of the pockets 3.
