Textiles Flächengebilde für ReinigungszweckeTextile fabric for cleaning purposes
Technisches GebietTechnical field
Die Erfindung betrifft ein textiles Flächengebilde für Reinigungszwecke mit einem vollflächigen Flor aus von einem Trägermaterial abstehenden Fasern unterschiedlicher Faserfeinheit, wie sie beispielsweise in Reinigungstüchern für die Bodenreinigung verwendet werden.The invention relates to a textile fabric for cleaning purposes with a full-surface pile of fibers of different fiber fineness protruding from a carrier material, as are used, for example, in cleaning cloths for floor cleaning.
Stand der TechnikState of the art
Bei bekannten Wischbezügen besteht der Flor zur Verbesse- rung der Reinigungseigenschaften oftmals aus einer Mischung verschiedener aus Baumwollfäden und Kunstfasern. Die Kunstfasern haben in der Regel gegenüber den Baumwollfasern einen höheren Fasertiter und sollen die Scheuerleistung verstärken.In the case of known wiping covers, the pile for improving the cleaning properties often consists of a mixture of different cotton threads and synthetic fibers. The synthetic fibers generally have a higher fiber titer than the cotton fibers and are intended to increase the abrasion performance.
Nachteilig hierbei ist, daß bei flächigen Verunreinigungen die einzelnen Kunststoffasern jede für sich wirken und daß die Reinigungsleistung bzw. die angestrebte Wirkung nur unzureichend erzielt wird. Der Erhöhung des Anteils der Kunststoffasern steht die Einschränkung der Wasseraufnahme entgegen.The disadvantage here is that in the case of flat impurities, the individual plastic fibers each work individually and that the cleaning performance or the desired effect is achieved inadequately. The increase in the proportion of synthetic fibers is opposed to the restriction of water absorption.
Weiterhin ist aus dem DE-GM 94 02 509 eine Reinigungseinrichtung bekannt, welche zwei in Arbeitsrichtung hinterein- ander angeordnete Abschnitte aufweist, die jeweils an einem Trägermaterial befestigte Fasern enthalten, welche mit einem freien Ende vom Trägermaterial abstehen und von denen der eine Abschnitt für die Reinigung geeignete Fasern und der zweite Abschnitt zum Trockenwischen geeignete Fasern oder dergleichen aufweist. Hier handelt es sich um eineFurthermore, a cleaning device is known from DE-GM 94 02 509, which has two sections arranged one behind the other in the working direction, each on one Carrier material contain attached fibers which protrude from the carrier material with a free end and of which one section has fibers suitable for cleaning and the second section has fibers or the like suitable for dry wiping. This is a
Lehre zur Konfektionierung von Wischbezügen, d.h. ausgehend von bekannten Textilien wird durch Zusammenstellen der gewünschte Effekt erzielt. Das Material selbst, also die Rei- nigungstextilie, wird nicht verändert. Auch das DE-GM 94 21 401 betrifft die Konfektionierung einer Reinigungstextilie, nicht aber das Material selbst.Teaching to assemble mop covers, i.e. starting from known textiles, the desired effect is achieved by combining them. The material itself, ie the cleaning textile, is not changed. DE-GM 94 21 401 also concerns the assembly of cleaning textiles, but not the material itself.
Aufgabe der Erfindung ist es daher, ohne die Anzahl der Fasern insgesamt zu erhöhen, die Gesamtwirkung der vorhan- denen einzelnen Fasern zu steigern.The object of the invention is therefore to increase the overall effect of the individual fibers present without increasing the total number of fibers.
Darstellung der ErfindungPresentation of the invention
Dadurch, daß in dem Flor aus mehreren Einzelfasem beste- hende Faserbereiche gebildet werden, deren durchschnittliche Faserfeinheit sich von der durchschnittlichen Faserfeinheit umliegender Zonen unterscheidet, werden funktio- nell einheitliche Bereiche geschaffen, in denen sich die einzelnen Fasern gegenseitig unterstützen.Due to the fact that fiber areas consisting of several individual fibers are formed in the pile, the average fiber fineness of which differs from the average fiber fineness of surrounding zones, functionally uniform areas are created in which the individual fibers support each other.
Insgesamt können mehrere verschiedene Faserbereiche in dem textilen Flächengebilde verwirklicht sein, um mehrere verschiedene funktioneile Eigenschaften zu vereinen.Overall, several different fiber areas can be realized in the textile fabric in order to combine several different functional properties.
Zur Herstellung eines Reinigungstuchs ist als Unterscheidungsgrenze ein Faserfeinheitswert im Bereich von 1 dtex bis 200 dtex, vorzugsweise zwischen 1 dtex und 20 dtex vorteilhaft. In diesem Bereich werden für die Reinigung unterschiedliche Eigenschaften der Faserbereiche erzeugt. Die durchschnittliche Faserfeinheit der Faserbereiche gegenüber den umliegenden Zonen soll sich um mindestens 2 dtex unterscheiden, um eine klare Funktionstrennung herzustellen.A fiber fineness value in the range from 1 dtex to 200 dtex, preferably between 1 dtex and 20 dtex, is advantageous as a differentiation limit for producing a cleaning cloth. Different properties of the fiber areas are generated in this area for cleaning. The average fiber fineness of the fiber areas compared to the surrounding zones should differ by at least 2 dtex in order to establish a clear separation of functions.
Vorteilhaft ist ebenfalls die Verwendung anderer Faserarten bzw. anderer Fasermischungen für die Faserbereiche gegenüber den umliegenden Zonen. Dadurch werden grundsätzlich verschiedene Funktionen, beispielsweise Wasseraufnahme und Schmutzlösung durch eine jeweils geeignete Faserart bzw. Fasermischung angepaßt.It is also advantageous to use other types of fibers or other fiber mixtures for the fiber areas compared to the surrounding zones. As a result, various functions are fundamentally adapted, for example water absorption and dirt dissolution by a suitable type of fiber or fiber mixture.
Werden die Faserbereiche als Faserinseln ausgebildet, d.h. allseitig von der umliegenden Zone umschlossene Bereiche, so wird eine beliebige Verteilung gemäß dem Einsatzzweck ermöglicht. Insbesondere lassen sich ungleichmäßige Verteilungen mit besonders aktiven Bereichen erzielen.Are the fiber areas formed as fiber islands, i.e. Areas enclosed on all sides by the surrounding zone, so any distribution is possible according to the purpose. In particular, uneven distributions with particularly active areas can be achieved.
Auch die zusammenhängende Ausbildung der Faserbereiche un- tereinander, beispielsweise in Form eines Gitters, läßt eine dem Einsatzzweck entsprechende Gestaltung des textilen Flächengebildes zu.The coherent formation of the fiber areas with one another, for example in the form of a grid, also allows the textile fabric to be designed in accordance with the intended use.
Beide vorgenannten Weiterbindungen können derart ausgeführt werden, daß eine Wirkungsisotropie gegeben ist, d.h. sich die Effekte in allen Anwendungsrichtungen auswirken.Both of the aforementioned connections can be carried out in such a way that there is an isotropy of action, i.e. the effects affect all areas of application.
Ist eine bevorzugte Anwendungsrichtung gewünscht, so können die Faserbereiche in Form von im wesentlichen linearen Streifen ausgebildet sein.If a preferred direction of use is desired, the fiber areas can be in the form of essentially linear strips.
Stark verschlungene Streifen, beispielsweise ein Wellenmuster, bei dem sich die Wellentäler und Wellenberge der Streifen überlappen, führen wiederum zu einer Abschwächung der Anisotropie. Um eine weiter verbesserte Unterstützungswirkung zu erzielen, beträgt die Mindestfläche der einzelnen Faserbereiche, gemessen in einem Millimeter Abstand über dem Trägermateri- al, 4 mm2.Heavily intertwined strips, for example a wave pattern in which the wave troughs and wave crests of the strips overlap, in turn lead to a weakening of the anisotropy. In order to achieve a further improved support effect, the minimum area of the individual fiber areas, measured at a millimeter distance above the carrier material, is 4 mm 2 .
Besonders vorteilhaft ist es, wenn die Fläche der Faserinseln über 20 mm2 beträgt, da hier zu der funktionellen Wirkungsverstärkung auch optisch wahrnehmbare Muster gestalten lassen.It is particularly advantageous if the area of the fiber islands is over 20 mm 2 , since optically perceptible patterns can also be designed here for the functional enhancement.
Die Vorteile der Erfindung werden schon mit einer Faserdichte von mindestens 500 Faserenden pro cm2 erreicht.The advantages of the invention are achieved with a fiber density of at least 500 fiber ends per cm 2 .
Je nach Anforderung können die Anzahl der Faserenden in den Faserbereichen bzw. der umliegenden Zone unterschiedlich sein, auch in den Faserbereichen untereinander.Depending on the requirements, the number of fiber ends in the fiber areas or the surrounding zone can be different, also in the fiber areas among one another.
Eine Weiterbildung besteht darin, die Florfasern so zuzu- führen, daß diese mehr als 1 mm vom Trägermaterial abstehen.A further development consists in feeding the pile fibers in such a way that they protrude more than 1 mm from the carrier material.
Zur Erzielung einer Wirkungsvielfalt mit einem textilen Flächengebilde ist es vorteilhaft, eine Unterscheidungs- grenze bei einem Faserfeinheitswert von 1 dtex und/oder eine Unterscheidungsgrenze bei einem Faserfeinheitswert von 3 bis 20 dtex anzusetzen. Die Fasern mit einem Faserfeinheitswert von unter 1 dtex werden als Mikrofasern bezeichnet und besitzen insgesamt eine hohe Oberfläche, wodurch die Schmutzaufnahme bereits gelöster Schmutzpartikel erfolgt. Gelöst wird der Schmutz von Fasern mit einem Faserfeinheitswert von mehr als 3 bis 20 dtex, die aufgrund der Eigenelastizität eine hohe Scheuerleistung aufweisen. Das zur Reinigung notwendige Wasser wird durch geeignete Fasern mit einem Faserfeinheitswert zwischen diesen vorgenannten Fasern aufgenommen , so daß eine Trocknung der Oberfläche stattfindet. Somit kann ein Tuch mit zwei oder drei Funktionen konfektioniert werden.To achieve a variety of effects with a textile fabric, it is advantageous to apply a differentiation limit for a fiber fineness value of 1 dtex and / or a differentiation limit for a fiber fineness value of 3 to 20 dtex. The fibers with a fiber fineness value of less than 1 dtex are called microfibers and have a high surface area overall, which means that dirt particles that have already been loosened are absorbed. The dirt is loosened from fibers with a fiber fineness value of more than 3 to 20 dtex, which have a high abrasion performance due to their inherent elasticity. The water required for cleaning is provided by suitable fibers recorded with a fiber fineness value between these aforementioned fibers, so that the surface dries. This means that a cloth with two or three functions can be assembled.
Das erfindungsgemäße textile Flächengebilde kann derart weitergebildet werden, daß Faserbereiche mit Scheuereffekt Schmutzlösung und Faserbereiche mit hoher Faseroberfläche zur Schmutzaufnahme in Zonen mit Fasern mit hoher Wasser- aufnähme eingebettet sind. In einem Wischvorgang wird der Schmutz gelöst, aufgenommen und die zu reinigende Fläche vom Putzwasser getrocknet. Mit einer angemessenen Verteilung und Gestaltung können also spezifische Reinigungseffekte mit gewissen Materialzonen verstärkt und Wirkungs- Synergien erzielt werden.The textile fabric according to the invention can be developed in such a way that fiber areas with a scouring effect, dirt solution and fiber areas with a high fiber surface for dirt absorption are embedded in zones with fibers with high water absorption. In a wiping process, the dirt is loosened, absorbed and the surface to be cleaned is dried by the cleaning water. With an appropriate distribution and design, specific cleaning effects can be enhanced with certain material zones and synergies can be achieved.
Eine Weiterbildung besteht darin, gestricktes Trägermaterial zu verwenden, von dem der Flor absteht. In den Träger können die Florfasern beispielsweise nach der Wildman- Technik zugeführt werden.A further development consists in using knitted carrier material from which the pile protrudes. The pile fibers can be fed into the carrier, for example, using the Wildman technique.
Zur Herstellung der Faserinseln ist es ausreichend, wenn im Verhältnis auf 1 bis 5 Inselmaschen auf 10 oder mehr Trägermaschen kommen. Dabei können die Trägermaschen mit den darin eingebundenen Fasern die umliegende Zone bilden.To produce the fiber islands, it is sufficient if there are 10 or more carrier meshes in relation to 1 to 5 island meshes. The carrier mesh with the fibers embedded in it can form the surrounding zone.
Kurzbeschreibung der ZeichnungBrief description of the drawing
Der Zeichnung sind verschiedene textile Flächengebilde für Reinigungszwecke dargestellt. Es zeigt:The drawing shows various textile fabrics for cleaning purposes. It shows:
Fig. 1 ein Reinigungstuch in Draufsicht mit Faserinseln unterschiedlicher Verteilung; Fig. 2 ein Reinigungstuch in Draufsicht mit zusammenhängenden Faserbereichen in Gitterform;Figure 1 is a cleaning cloth in plan view with fiber islands of different distribution. 2 shows a cleaning cloth in plan view with coherent fiber areas in lattice form;

Ausführung der ErfindungImplementation of the invention
Das in Fig. 1 dargestellte textile Flächengebilde ist ein Ausschnitt aus einem Reinigungstuch mit einem Flor aus Baumwollfasern und Kunstfasern. In die Zonen 1 aus Baum- wollfasern sind Faserinseln 2 aus Kunstfasern eingebettet und allseitig von den Baumwollfasern umgeben. Die Faserinseln 2 sind sowohl gleichmäßig über die Fläche verteilt, als auch in Bereichen 3 erhöhter Dichte angeordnet. Das Flächenverhältnis von Faserinseln 2 zu der Zone 1 beträgt über das gesamte Tuch gesehen weniger als 50 %.The textile fabric shown in Fig. 1 is a section of a cleaning cloth with a pile of cotton fibers and synthetic fibers. In the zones 1 made of cotton fibers, fiber islands 2 made of synthetic fibers are embedded and surrounded on all sides by the cotton fibers. The fiber islands 2 are both evenly distributed over the surface and arranged in areas 3 of increased density. The area ratio of fiber islands 2 to zone 1 is less than 50% over the entire cloth.
In Fig. 2 ist eine andere Verteilung der Faserbereiche 2 aus Kunstfasern mit hohem Faserfeinheitswert und der Zone 1 aus Baumwollfasern mit niedrigem Faserfeinheitswert darge- stellt. Es handelt sich um ein Gitternetz 4 aus Kunstfasern, welche Flächen 5 aus Baumwollfasern einschließen. Diese Flächen 5 bilden folglich selbst Inseln.FIG. 2 shows another distribution of the fiber areas 2 made of synthetic fibers with a high fiber fineness value and zone 1 made of cotton fibers with a low fiber fineness value. It is a grid 4 made of synthetic fibers, which include surfaces 5 made of cotton fibers. These surfaces 5 consequently form islands themselves.
Das in Fig. 1 und Fig. 2 dargestellte Reinigungstuch hat isotrope Wirkungseigenschaften, d.h. die Wirkung des Reinigungstuchs ist von der Bewegungsrichtung unabhängig.The cleaning cloth shown in Figs. 1 and 2 has isotropic properties, i.e. the effect of the cleaning cloth is independent of the direction of movement.
In Fig. 3 ist ein Reinigungstuch dargestellt, in welchem in einem Grundmaterial aus Baumwollfasern 1 Streifen 6, 7 aus Kunstfasern für Reinigungszwecke sowie Mikrofasern zur Schmutzaufnahme angeordnet sind. Dabei flankieren die aus Mikrofasern bestehenden Streifen 7 zur Schmutzaufnahme den aus Kunstfasern bestehenden streifen 6 zur Schmutzlösung beidseitig. Mit den Baumwollfasern l wird das Putzwasser aufgenommen und eine Trocknung herbeigeführt. Selbstverständlich können die Streifen 6, 7 unterbrochen sein, wodurch sich dann Faserinseln bilden.In Fig. 3, a cleaning cloth is shown, in which 1 strip 6, 7 of synthetic fibers for cleaning purposes and microfibers in a base material made of cotton fibers Dirt pickup are arranged. The strips 7 made of microfibers for dirt pickup flank the strips 6 made of synthetic fibers for dirt removal on both sides. The cleaning water is absorbed with the cotton fibers l and drying is brought about. The strips 6, 7 can of course be interrupted, as a result of which fiber islands are then formed.
Dieses Reinigungstuch ist in der Wirkung von der Bewegungs- richtung abhängig. Eine Bewegung in Richtung der Streifen 6, 7 führt nur zu einer Reinigung der verschmutzten Oberfläche in der Breite der Streifen 6, 7 der dazwischen liegend Zwischenraum 8 wird nicht gereinigt. In einer Bewegungsrichtung senkrecht zu den Streifen wird hingegen auf der gesamten Breite des Tuches eine Reinigungswirkung erzielt.The effectiveness of this cleaning cloth depends on the direction of movement. A movement in the direction of the strips 6, 7 only leads to a cleaning of the soiled surface in the width of the strips 6, 7 and the intervening space 8 is not cleaned. In a direction of movement perpendicular to the strips, however, a cleaning effect is achieved across the entire width of the cloth.
In Fig. 4 ist der Aufbau des Flächengebildes verdeutlicht. In einem Grundmaterial aus Baumwollfasern 1 mit einem Fa- serfeinheitswert von 1 bis 4 dtex sind Mikrofasern 9 mit einem Flächenfeinheitswert kleiner 1 dtex eingebettet, in die wiederum Kunstfasern 10 mit einem Faserfeinheitswert von größer 3 bis 20 dtex eingearbeitet sind. Dabei sind in den einzelnen Bereichen jeweils mehrere Einzelfasem der selben Art angeordnet.The structure of the fabric is illustrated in FIG. 4. Microfibers 9 with a surface fineness value of less than 1 dtex are embedded in a base material made of cotton fibers 1 with a fiber fineness value of 1 to 4 dtex, in which synthetic fibers 10 with a fiber fineness value of greater than 3 to 20 dtex are in turn incorporated. Several individual fibers of the same type are arranged in the individual areas.
Die das Flor 11 bildenden Faserenden 1, 9, 10 stehen von einem Träger 12 ab. Dabei kann jedes Faserende im wesentlichen gerade, beispielsweise 1 bis 30 mm lang, von dem Trä- ger 12 abstehen oder auch in sich verschlungen sein. The fiber ends 1, 9, 10 forming the pile 11 protrude from a carrier 12. In this case, each fiber end can protrude from the carrier 12 essentially straight, for example 1 to 30 mm long, or it can also be intertwined.
