Abstract

The cleaning cloth (10) is worked together with chenille yarns (11) over the whole surface, or in zones. The surface can be coated with a synthetic or natural product.

Description

The invention relates to a cleaning textile consisting of a flat structure with a cleaning bristle with a scraping effect. The Scraping effect in the context of the invention relates to the cleaning of a surface, that is removing dirt or the like from the surface, e.g. also ice cream from a window. The terms "scraping effect" or "scraping" therefore include in in the present context also a "scratching effect" or a "scratching" or similar abrasive effects or manipulations, only the dirt etc. removed, but the surface to be cleaned should not be damaged; the Scratch off material, but do not scratch it. For the sake of simplicity, following all these effects and manipulations with the terms Scraping effect, scraping, scraper-resistant, etc. summarized.

DE 295 06 393 U1 describes a cleaning textile with and in it embedded bristles described. The bristles can be made of monofilament or multifilament filament yarn. The material should be chosen and processed in this way be that it is in use, especially in damp and Wet cleaning, has a scraping effect, but the surface to be cleaned not scratched.

With the help of the well-known textile dirt should be scraped off without the to hurt the cleaning surface. These are contradicting claims difficult to reconcile in practice. Either they're in the base fabric bound bristles so soft that they have no scratching effect, then when pressing the cleaning textile, lie on the one to be cleaned Surface flat; this almost reduces the cleaning effect. On the other hand, if the bristles are made of relatively stiff and hard material, is the scratch effect to be avoided, especially if you are stuck Dirt presses harder, not to be excluded.

In US 39 45 736 a cleaning cover is described which consists of a fabric similar to a chenille material. In the known one becomes woven backing is a pole that is obviously made up of loops, which is supposed to form the mopping surface of a mob, classified.

In US 35 37 122 a polishing mop is described which is based on has tightly woven, heavy canvas, canvas or the like. In the 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 used to form individual tufts on the front of the base cut off. In this context, the familiar uses of chenille loops spoken. Since the cut loop ends according to Fig. 8 the Fray print, contain the sewn-in loops in the familiar of the Number of fringes corresponding to many soul threads, making it difficult can be chenille yarn in a technical sense.

In the DE book by Josef Lösch, specialist dictionary textile, Frankfurt 1975, (Keywords "chenille" and "chenille fabric") become some definitions given. Trimmings chenille and chenille twine are addressed as well Chenille pre-fabric. Today one differentiates in the relevant Experts depending on the type of manufacture between woven or knitted fabric, Zwirnchenille and Flockchenille (the latter is also known as flock yarn). Woven and knitted fabrics are made from a woven or knitted fabric produced by cutting and turning or solidifying. From this The so-called chenille fabrics are also pre-formed. These are velvet-like fabrics, the weft of "woven" or "knitted" Yarn exists. The main characteristics of such chenille fabrics are the big ones Voluminosity and the soft feel. Chenille fabrics are made into scarves, Towels, washcloths and / or city and beach clothes (cf. the aforementioned quote from Josef Lösch); So relatively soft throughout Flat structures whose surface should not have a scraping effect.

EP 0091 676 B1 describes a chenille woven or knitted fabric. In the goods are worked into a chenille yarn, which consists of between two Threads together with a band of relatively low melting point intertwined pile fibers. The yarn is replaced by a corresponding Fused with the ribbon attached. In the known, a chenille yarn is said to be synthetic pile fibers with a fineness less than 1.0 tex are used, to create a chenille textile with a soft feel, silky sheen. To According to the information in the publication, the chenille textile can not only be used as Garment fabric but also in other fields for the production of industrial and constructive materials, decorative items, sheets, sacks, etc. be used. Because of the soft grip sought, there is obviously one Scraping effect, as with a cleaning textile, is not desirable.

Other synthetic man-made chenille fabrics used for decorative purposes are to be trained with a special pattern and a close sequence of shots DE 29 00 008 B1 and DE 29 48 788 A1 specified. The well-known Chemical fiber chenille fabrics are said to be resistant to mechanical loads or the surface appearance should be mechanical Load remains unchanged, but it should be a furniture, decoration or clothing material that is resistant to mechanical Equipment or cleaning operations must be, but apparently one 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 a long one Has durability. The cleaning textile should be made from a flat fabric a cleaning bristle having a scraping effect. The Bristles of the bristle should at the same time be so flexible that they are too tight Do not scratch the cleaning surface - at least not annoyingly - and so strongly or be hard that - at least when pressed - essentially perpendicular to the surface to be cleaned. Becomes stiff or hard or abrasive a bristle pronounced within the scope of the invention if it is their Application task is able to clean a surface accordingly, without noticeably hurting them.

The solution according to the invention exists for the above Cleaning textile in that the cleaning bristles from a scrape stiff or - hard-set pile fiber layer of a whole or in some areas in the Chenille yarns of the chenille thread type or incorporated in flat structures Flock yarn (with a soft core relative to the pile fiber layer) is made. Some Improvements and further refinements of the invention are in the Subclaims described.

This preferably means that according to the invention in the cleaning textile Chenille yarns set abrasively over the entire surface or in some areas in the pile are incorporated. In particular, to produce the pile fiber layer Chenille yarn uses stiff and hard mono or multifile. The terms In this context, "soft and hard" are defined as follows: The fibers should be stiff or hard or abrasive enough to remove dirt from one surface to be cleaned, but they should not be so stiff or hard or be abrasive so that the surface to be cleaned is the same as for the Grinding or lapping, hurt. Chenille threads set accordingly or flock yarn are particularly useful in experiments within the scope of the invention proven.

According to the invention, the cleaning bristle having a scraping effect is seated - in contrast to the known - not on the fabric as such, but on elements of the fabric, namely on the Fabric integrated or representing the fabric Chenille yarn. The yarn can according to the invention in the form of Loops can be integrated and / or within the scope of the invention Chenille yarn ends like poles and like bristles, e.g. vertical, from the surface protrude.

These projecting yarn ends do not represent according to another invention (always) immediately represent the cleaning bristles, namely when the The pile fiber layer of the yarn forms the bristles. This applies in particular if the soul of each individual chenille yarn softer or more flexible than the fibers of the yarn pole and thus the bristle carrier forming the yarn core more flexible than the bristles formed by the pile fiber layer.

Alternatively, according to yet another invention, it can also be cheap, the yarn core, hard or stiff (within the scope of the present definition) choose an appropriate chenille yarn. Those in the literature In such a configuration, the bristles described themselves have a side or radially protruding, preferably "scrape-stiff", bristle pile or pole.

Surprisingly, when using an inventive Cleaning textile the fibers of the pile, that is, the actual inventive Cleaning bristles, regardless of how strong you are against the textile cleaning surface presses, essentially always perpendicular to the surface. Each the more you push the textile against the surface, the more (i.e. one more larger number of) fibers of the bristle (essentially perpendicular) to the area. This becomes particularly clear when you consider the invention Cleaning textile - like a bristle brush - with a velvety pole protruding chenille yarn ends. If you have such a structure only pushes against a surface with little force, for example only touches the surface Yarn tips with a few fiber tips that are stiff relative to the yarn core trained poles the area. If you press harder against the one to be cleaned Surface, the relatively soft souls of the yarn are bent over and in The greater part of the pile fiber layer of each individual chenille yarn sweeps over it Area.

In contrast to every known brush - in which the bristles differ from one certain pressure to apply and become ineffective - become according to the invention, the more one cleans the textile against one to be cleaned Surface presses the more cleaning bristles towards the one to be cleaned Surface erected, i.e. with the cleaning task the number of Cleaning bristles and thus the cleaning power. It can possibly are attributed to the structure of the chenille yarn pile or pile (with the approximate radial arrangement of the bristles forming the pole of the single fiber) which in combination in the respective textile also on the side to be cleaned Surface and can achieve the desired scraping effect.

The effect to be achieved by the invention is surprisingly already achieved in that the entire surface or in the cleaning textile in some areas by using stiff and hard mono- and Multi-filament abrasive chenille yarns incorporated. That applies especially if the increased cleaning effect with greater pressure essentially by increasing the surface relative to the surface to be cleaned upright pile fibers is reached, and a bending of the consciously relative soft souls of chenille yarn do not result in premature fatigue has the durability of a cleaning textile designed according to the invention also relatively high.

Using the invention, it was found that the generation of scraping or high abrasive effect by the introduction of correspondingly abrasive flock yarns and / or chenille threads possible is. If necessary, the material should be selected and processed so that it its in use, especially in wet and wet cleaning has a scraping or abrasive effect, but not the surface to be cleaned scratched.

Basically, can be used to manufacture the cleaning textile according to the invention every plastic fiber and every common textile production method is used become. The fibers, fiber blends, yarns and yarn combinations are processed according to 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 or with other common Processed laminate and the like can be used.

An advantageous further development, in particular for a cleaning textile is good for rinsing, is that the pile fiber of the chenille yarn consists of plastic, polyester or polyamide in particular are suitable. Another advantageous development, which, in particular for the floor cleaning is particularly suitable, is that the Pole layer of chenille yarn made of plastic, natural and / or viscose fibers consists; there can also be different types of chenille yarn in one Cleaning textile can be incorporated, so that you get the typical Maintains cleaning effects at the same time. Preferred as a natural fiber Cotton in question. If the end product is a particularly good one Should have water storage capacity, it can be beneficial in the pole layer bring in a lot of cotton or viscose. Basically, it can Cleaning textile also a pole made of pure cotton (and / or viscose etc.) if the chenille yarn is worked into the base of the pole.

Ultimately, the invention relates to a cleaning textile consisting of a Flat structures 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 can also be pressed on standing upright, the bristle is set from a scraper-resistant Pole fiber layer of a chenille yarn worked into the fabric manufactured. According to the invention, the pile fiber layer of the chenille yarn preferably monofilament staple fibers, plastic staple fibers, natural fibers, Viscose staple fibers, ramie fibers, continuous plastic staple fibers and / or contain a mixture of these materials.

schematic sectional drawings of cleaning textiles according to the invention.

Fig. 1 shows a cleaning fabric designated overall by 10, the can be used for example for a household towel. The cleaning textile consists in the illustrated embodiment of a fabric with a chain 1st and weft 2 with chenille yarn incorporated therein (not shown). It is particularly preferred if the chenille yarn is woven or is acted upon 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) like a pile protrudes with free yarn ends, because in these cases by the invention Surprisingly obtained advantage that the number of in The direction of the cleaning bristles on the surface to be cleaned increases becomes particularly concise.

In addition, it can be beneficial to have the cleaning textile on one or both sides to provide a coating of plastic or natural products. For example, such a cleaning textile coated with synthetic leather, which is also equipped according to the invention with an abrasive, for cleaning and Drying of glass, mirrors or the like can be used. Depending on Coating comes within the scope of the invention also a wiping or Cleaning cloth - of course with the abrasive according to the invention Areas - in question.

Due to the chenille yarn incorporated according to the invention, a high abrasive effect of the cleaning textile achieved; furthermore this remains Get cleaning effect over a relatively long time, for example if that Textile by choice of components and / or by moistening when wiping at the same time eliminates any electrostatic charge.

2 and 3 show two with particular advantage in the context of the invention usable types of chenille yarn. In Fig. 2 Chenille thread 3, in Fig. 3rd Flock yarn 4 shown in principle. The chenille thread 3 consists of two soul threads 5 twisted together, between which when twisting or Twisting a plurality of fiber sections 6, e.g. Staple fibers that overall form the pole 7, is frictionally integrated. 3 is a soul thread 8 surrounded with an adhesive layer 9, which the 7th integrating fiber sections 6 integrally. One soul thread 8 of the flock yarn 4 according to FIG. 10 can be a thread spun from fibers also be a monofilament. The from at least two soul threads 5 existing soul of the chenille thread 3, on the other hand, cannot, in principle, in any case not as a whole, as monofilament, since always at least two threads are required.

As shown schematically in FIGS. 4 to 11, there are many Ways of using chenille yarn 11 in a cleaning textile according to the invention to incorporate. 4 can be part of the warp 1 form a fabric.

The chenille yarn 11 can be bristle-shaped or plush-shaped according to FIGS. 5 and 7 from a surface above, for example using a double velvet weaving process, be incorporated into the cleaning textile 10. But it can also 6 as a continuous warp thread on both sides of the top of the surface Cleaning textile 10 lie; at the same time, a normal one, not as chenille yarn trained warp thread form a pole. 8, the chenille yarn alternately lie flat on the surface of a fabric and one at a time or skip several weft threads 2. An execution according to is preferred Fig. 9 with a warp thread 11 which is partly, i.e. on individual periodically or non-periodically repeating positions, in the form of loops 13, in particular as with terry toweling, which projects from the woven fabric.

4 to 9, a fabric is spoken of as an example. As part of However, the invention applies in principle the same if the basis of Cleaning textiles as knitted, knitted, crocheted or Raschelware or one other goods composed of individual threads. Basically The invention also extends to tufted materials and nonwovens or without pile fibers. For example, FIGS. 10 and 11 show one in one Nonwoven fabric 12 sewn or embroidered pattern of the invention provided chenille yarn. 11, the chenille yarn 11 in the Nonwoven 12 may be classified, for example.

The chenille yarn can be sewn, embroidered or onto the cleaning textile also be quilted. In the sense of solving the task mentioned at the beginning it is preferred if the chenille yarn is thread-like in the cleaning textile is incorporated and / or over large areas of the cleaning textile protrudes, i.e. protrudes from the outside of the surface of the textile. Particularly preferred cleaning textiles, on one surface of which the chenille yarn is used Loops abut and on the other surface with free ends, like a pole, protrudes.
