Der Einfachheit halber werden im folgenden alle diese Wirkungen und Handhabungen mit den Begriffen Schabwirkung, schaben, schabsteif usw. zusammengefaßt umschrieben.The invention relates to a cleaning textile consisting of a flat structure with a cleaning bristle having a scraping effect. In the context of the invention, the scraping effect relates to the cleaning of a surface, ie the removal of dirt or the like from the surface, for example also ice from a window. The terms

Scraping effect "or

Cockroaches "therefore also include in the present context

Scratching effect "or a

Scratching "or similar abrasive effects or manipulations, whereby only the dirt etc. should be removed, but the surface to be cleaned should not be damaged; scrape off but not scratch the material. For the sake of simplicity, all of these effects and manipulations are described below with the terms Scraping effect, scraping, scraper-resistant, etc. summarized.

DE 295 06 393 U1 describes a cleaning textile with a base fabric and bristles embedded therein. The bristles can consist of monofilament or multifilament filament yarn. The material should be selected and processed in such a way that it has a scraping effect when used, in particular in wet and wet cleaning, but does not scratch the surface to be cleaned.

With the help of the known textile, dirt should be scraped off without damaging the surface to be cleaned. These are contradicting claims difficult to reconcile in practice. Either the bristles embedded in the base fabric are so soft that they do not have a scratching effect, then they lie flat against the surface to be cleaned when the cleaning textile is pressed on; this almost reduces the cleaning effect. If, on the other hand, the bristles are made of relatively stiff and hard material, the scratching effect to be avoided cannot be ruled out, especially if one presses hard with stuck dirt.

In US 39 45 736 a cleaning cover is described, which is to be made from a fabric similar to a chenille material. In the known, a pole, which obviously only consists of loops and is supposed to form the mopping surface of a mob, is classified into a woven backing material.

In US 35 37 122 a polishing mop is described, which has a base of tightly woven, heavy canvas, canvas or the like. Loops made of relatively thick wool yarn are sewn into the base. The yarn loops themselves lie on the back of the base, the free ends of the loops are cut off to form individual tufts on the front of the base. In this context, the familiar is referred to as chenille loops. Since the cut-off loop ends fray according to FIG. 8 of the publication, the sewn-in loops in the known item contain a number of soul threads corresponding to the number of fringes, so that it can hardly be chenille yarn in the technical sense.

Chenille" und

Chenille-Gewebe") werden einige Definitionen gegeben. Angesprochen werden Posamenten-Chenille und Chenille-Zwirn sowie Chenille-Vorware. In heutiger Zeit unterscheidet man in der einschlägigen Fachwelt je nach Herstellungsart zwischen Web- oder Wirkchenille, Zwirnchenille und Flockchenille (letztere wird auch als Flockgarn bezeichnet). Web- und Wirkchenille werden aus einer gewebten oder gewirkten Vorware durch Aufschneiden und Drehen bzw. Verfestigen hergestellt. Aus dieser Vorware werden auch die sogenannten Chenille-Gewebe gebildet. Das sind samtartig wirkende Gewebe, deren Schuß aus

gewirktem" Garn besteht. Die Hauptmerkmale solcher Chenille-Gewebe sind die große Voluminosität und der weiche Griff. Man verarbeitet Chenille-Gewebe zu Schals, Handtüchern, Waschlappen und/oder Stadt- und Strandkleidern (vgl. das vorgenannte Zitat von Josef Lösch); also zu durchweg relativ weichen Flächengebilden, deren Oberfläche eine Schabwirkung nicht aufweisen soll.In the DE book by Josef Lösch, specialist dictionary textile, Frankfurt 1975, (keywords

Chenille "and

Chenille fabrics ") are given some definitions. Trimmings chenille and chenille twine as well as chenille pre-fabric. Today, depending on the type of manufacture, a distinction is made in the relevant specialist world between woven or knitted, floss and flockchenille (the latter is also called Woven and knitted fabrics are made from a woven or knitted fabric by cutting and turning or consolidating The so-called chenille fabrics are also pre-formed. These are velvet-like fabrics, the weft of which

The main features of such chenille fabrics are the large volume and the soft feel. Chenille fabrics are processed into scarves, towels, washcloths and / or city and beach clothes (cf. the aforementioned quote by Josef Lösch) to consistently relatively soft fabrics whose surface should not have a scraping effect.

EP 0091 676 B1 describes a chenille woven or knitted fabric. A chenille yarn is worked into the fabric, which consists of pile fibers twisted between two threads together with a ribbon of relatively low melting point. The yarn is fastened by appropriately fusing with the tape. In the known, a chenille yarn with synthetic pile fiber with a fineness of less than 1.0 tex is to be used in order to create a chenille textile with a soft touch and a silky sheen. According to the information in the publication, the chenille textile can be used not only as a clothing fabric but also in other areas for the production of industrial and constructive materials, decorative items, sheets, sacks, etc. Because of the desired soft grip, a scraping effect, as with a cleaning textile, is obviously not desirable.

Further synthetic chemical fiber chenille fabrics which are to be designed for decorative purposes with a special pattern and close weft sequence are specified in DE 29 00 008 B1 and DE 29 48 788 A1. The known chemical fiber chenille fabrics are supposed to be resistant to mechanical loads or the surface appearance should remain unchanged when subjected to mechanical loads, but it should be a furniture, decoration or clothing fabric that has to be resistant to mechanical finishing or cleaning processes but apparently must not have a scraping effect of a cleaning textile.

The invention has for its object to provide a cleaning textile which on the one hand has a good cleaning effect and on the other hand has a long shelf life. The cleaning textile should consist of a flat structure with a cleaning bristle having a scraping effect. The bristles of the bristle should at the same time be so flexible that they do not scratch - at least not disturbingly - a surface to be cleaned, and are so strong or hard that they are - at least when pressed - essentially perpendicular to the surface to be cleaned. Within the scope of the invention, a bristle is pronounced as stiff or hard or abrasive if it is capable of cleaning a surface according to its application task, without noticeably injuring it.

The solution according to the invention for the cleaning textile mentioned at the outset is that the cleaning bristles consist of a shaved or hard-set pile fiber layer of a chenille yarn of the type of chenille thread or flock yarn incorporated into the fabric over the whole area or in regions (with a soft core relative to the pile fiber layer) ) consists. Some improvements and further refinements of the invention are described in the subclaims.

weich und hart" werden in diesem Zusammenhang folgendermaßen definiert: Die Fasern sollen steif oder hart bzw abrasiv genug sein, um Schmutz von einer zu reinigenden Fläche abzuheben, sie sollen aber nicht so steif oder hart bzw abrasiv sein, daß sie bei dieser Arbeit die zu reinigende Fläche, etwa wie beim Schleifen oder Läppen, verletzen. Entsprechend eingestellte Chenille-Zwirne oder Flockgarn haben sich bei Versuchen im Rahmen der Erfindung besonders bewährt.This preferably means that, according to the invention, chenille yarns are incorporated into the cleaning textile over the entire surface or in some areas in the pile. In particular, rigid and hard monofilament or multifilament are used to produce the pile fiber layer of the chenille yarn. The terms

soft and hard "are defined in this context as follows: The fibers should be stiff or hard or abrasive enough to lift dirt off a surface to be cleaned, but they should not be so stiff or hard or abrasive that they do the job surface such as grinding or lapping, and accordingly adjusted chenille threads or flock yarn have proven particularly useful in experiments within the scope of the invention.

According to the invention, the cleaning bristle having a scraping effect - in contrast to the known - does not sit on the flat structure as such, but on elements of the flat structure, namely on chenille yarn which is integrated into the flat structure or represents the flat structure. According to the invention, the yarn can be integrated into the surface in the form of loops and / or in the context of the invention, chenille yarn ends can be like poles and like bristles, e.g. protrude vertically from the surface.

According to a further invention, these projecting yarn ends do not (always) directly represent the cleaning bristles, namely when the pile fiber layer of the yarn forms the bristles. This is particularly true when the core of each individual chenille yarn is softer or more flexible than the fibers of the thread pile and thus the bristle carrier forming the thread core is more flexible than the bristles formed by the pile fiber layer.

schabsteifen", Borstenflor bzw. -pol.Alternatively, according to yet another invention, it may also be advantageous to make the yarn core, hard or stiff, (within the scope of the present definition) or to select an appropriate chenille yarn. In such a configuration, the bristles described in the literature themselves have a side or radial protrusion, preferably

scraper ", bristle pile or pile.

Surprisingly, when using a cleaning textile according to the invention, the fibers of the pile, ie the actual cleaning bristles according to the invention, are essentially always perpendicular to the surface, regardless of how hard the textile is pressed against the surface to be cleaned. The more you press the textile against the surface, the more (ie the greater the number of) fibers of the bristle encounter (essentially perpendicular) on the surface. This becomes particularly clear when the cleaning textile according to the invention - like a brush with bristles - is equipped with a pole of velvety protruding chenille yarn ends. If you press such a structure against a surface with only a small force, only those touch, for example Yarn tips with a few fiber tips of the pole, which is designed to be scrape-stiff relative to the yarn core, cover the surface. If you press harder against the surface to be cleaned, the relatively soft souls of the yarn are bent over and a larger part of the pile fiber layer of each individual chenille yarn sweeps over the surface.

In contrast to any known brush - in which the bristles turn over and become ineffective from a certain pressing force - according to the invention, the more the cleaning textile is pressed against a surface to be cleaned, the more cleaning bristles are raised in the direction of the surface to be cleaned, ie with the cleaning task, the number of cleaning bristles and thus the cleaning power increases. This can possibly be attributed to the structure of the chenille yarn pile or pile (with the approximately radial arrangement of the bristles forming the pile of the single fiber) which, in combination in the respective textile, also lie laterally on the surface to be cleaned and can thus achieve the desired scraping effect.

The effect to be achieved by the invention is surprisingly achieved by incorporating the chenille yarns, which are abrasively adjusted by using stiff and hard mono- and multifilaments, over the entire surface or in some areas of the cleaning textile. This is especially true if the increased cleaning effect with greater pressure is essentially achieved by increasing the pile fibers erected relative to the surface to be cleaned, and bending the deliberately relatively soft core of the chenille yarn does not result in premature fatigue is the durability of one Cleaning textile designed according to the invention is also relatively high.

When using the invention it was found that the generation of the scraping or high abrasive effect is possible by the introduction of correspondingly abrasive flock yarns and / or chenille threads. If necessary, the material should be selected and processed so that it it has a scraping or abrasive effect when used, especially when damp and wet cleaned, but does not scratch the surface to be cleaned.

In principle, any plastic fiber and any common textile production method can be used to manufacture the cleaning textile according to the invention. The fibers, fiber blends, yarns and yarn combinations are processed depending on the given application in the context of the invention so that the resulting textiles for dry wiping, damp wiping and wet wiping, for example as a cleaning cloth, cleaning sponge, cleaning glove, cleaning tape and / or cleaning disc (for cleaning machines) as glued , sewn laminate or the like produced by other common methods, and the like, can be used.

An advantageous further development, which is particularly suitable for a cleaning textile for rinsing, consists in the fact that the pile fiber of the chenille yarn consists of plastic, polyester or polyamide being particularly suitable. Another advantageous development, which is particularly well suited, in particular, for floor cleaning, is that the pile layer of the chenille yarn consists of plastic, natural and / or viscose fibers; Chenille yarn of different types can also be incorporated into a cleaning textile, so that the corresponding typical cleaning effects are obtained at the same time. Cotton is the preferred natural fiber. If the end product is to have a particularly good water storage capacity, it can be advantageous to introduce a relatively large amount of cotton or viscose into the pile layer. Basically, the cleaning textile can also have a pile of pure cotton (and / or viscose, etc.) if the chenille yarn is incorporated into the base of the pile.

Ultimately, the invention relates to a cleaning textile consisting of a flat structure with a cleaning bristle having a scraping effect. To achieve that the bristles are so soft that they do not scratch, and at the same time are so hard that they stand upright even when pressed on, the bristles are made from a polypropylene layer set to be stiff against scraping and of chenille yarn incorporated into the fabric. According to the invention, the pile fiber layer of the chenille yarn can preferably contain monofilament staple fibers, plastic staple fibers, natural fibers, viscose staple fibers, ramie fibers, continuous plastic staple fibers and / or a mixture of these materials.

schematic sectional drawings of cleaning textiles according to the invention.

FIG. 1 shows a cleaning textile, designated overall by 10, which can be used, for example, for a household towel. The cleaning textile consists in the illustrated embodiment of a fabric with warp 1 and weft 2 with chenille yarn incorporated therein (not shown). It is particularly preferred if the chenille yarn is woven or knitted and / or if at least on one side of the fabric, the chenille yarn as such (also over the whole area or in some areas) projects like a pole with free yarn ends, because in these cases the invention Surprisingly obtained advantage that the number of cleaning bristles raised in the direction of the surface to be cleaned increases with the pressing force, is particularly striking.

In addition, it can be favorable to provide the cleaning textile with a coating of plastic or natural products on one or both sides. For example, such a cleaning textile coated with synthetic leather, which at the same time has an abrasive finish according to the invention, can be used for cleaning and drying glass, mirrors or the like. Depending on the coating, a wiping or cleaning cloth - of course with the abrasive areas according to the invention - is also possible within the scope of the invention.

The chenille yarn incorporated according to the invention achieves a high abrasive effect on the cleaning textile; furthermore this remains Maintain a cleaning effect over a relatively long period of time, for example if the textile at the same time eliminates any electrostatic charge due to the choice of components and / or moistening when wiping.

2 and 3 show two types of chenille yarn which can be used with particular advantage in the context of the invention. In Fig. 2 chenille thread 3 is shown in Fig. 3 flock 4 in principle. The chenille thread 3 consists of two core threads 5 twisted together, between which a plurality of fiber sections 6, e.g. Staple fibers, which together form the pole 7, is non-positively integrated. According to FIG. 3, a core thread 8 is surrounded with an adhesive layer 9, which integrally integrates the fiber sections 6 forming the pole 7. The one core thread 8 of the flock yarn 4 according to FIG. 10 can be a thread spun from fibers but also a monofilament filament. In contrast, the core of the chenille thread 3 consisting of at least two core threads 5 cannot in principle, at least not overall, be described as monofilament, since at least two threads are always required.

As shown schematically in FIGS. 4 to 11, there are many possibilities for incorporating chenille yarn 11 into a cleaning textile according to the invention. 4 can form part of the warp 1 of a fabric.

5 and 7, the chenille yarn 11 can be worked into the cleaning textile 10 in a bristle-like or plush form from a surface protruding, for example using a double velvet weaving method. 6, however, it can also lie on both sides on the surface of the cleaning textile 10 as a continuous warp thread; at the same time, a normal warp thread that is not designed as chenille yarn can form a pile. 8, the chenille yarn can alternately lie flat on the surface of a fabric and in each case jump over one or more weft threads 2. An embodiment according to FIG. 9 is preferred with a warp thread 11 which is partly or periodically or individually non-periodically repeating positions, in the form of loops 13, in particular also as in terry goods, protrudes from the woven fabric.

4 to 9, a fabric is spoken of as an example. In the context of the invention, however, the same applies in principle if the basis of the cleaning textile consists of knitted, knitted, crocheted or knitted goods or another product composed of individual threads. Basically, the invention also extends to tufted materials and nonwovens with or without pile fibers. For example, FIGS. 10 and 11 show a pattern of the chenille yarn provided according to the invention sewn or embroidered into a nonwoven 12. 11, the chenille yarn 11 can be tufted into the nonwoven 12, for example.

The chenille yarn can be sewn onto the cleaning textile, embroidered on or stitched on. In order to achieve the object mentioned at the outset, it is preferred if the chenille yarn is incorporated into the cleaning textile in a thread-like manner and / or protrudes beyond large areas of the cleaning textile, ie projects outside of the surface of the textile. Cleaning textiles are also particularly preferred, on one surface of which the chenille yarn lies in loops and on the other surface with free ends, like a pole, protruding.
