Cleaning cloth with detergent depot.

The invention relates to a cleaning cloth with detergent depot, which can be used in particular as household cleaning cloth, but which also for cleaning windshields for automobiles, for office cleaning and, where appropriate a) I can be used for machine and equipment maintenance in commercial establishments.

Cleaning cloths that are provided with a detergent depot are known per se. For example, in German utility model no. 18 84 kiO, a window cleaning cloth is described which consists of an absorbent fabric that is completely soaked with an emulsion of a non-ionic soap, a cleaning body and a carrier. For example, the sodium salt of a fatty alcohol ether sulfate is proposed as a non-ionic soap and methylcellulose mucilage as a carrier. Cleaning cloths diesei ^one known type prepare insofar trouble when the water-soluble fixing agent not being able to hold the detergent substance at a sufficient water supply for a long time on the cloth matrix. The effectiveness of the detergent depot is therefore low because such wipes are often only suitable for single use.

A sponge filled with soap is known from German Offenlegungsschrift No. 2k hk 37k , in which the aforementioned difficulty of sufficiently long depot effect is circumvented in that a compact bar of soap is arranged inside the sponge, which naturally lasts as long as this is known from a bar of soap. Products of this type cannot, however, be produced in the form of a cloth, so that they can be used for personal cleaning purposes, but not for building cleaning, window cleaning and the other areas of application mentioned at the beginning.

In this prior art, the task is to provide a cleaning cloth with detergent depot, its Depot effect leg; G-e use persists over a long period of time,

Phases of use without premature exhaustion of the depot survives.

According to the invention, this object is achieved in that the cloth contains nonionic, weakly polar wetting agents which are bound to anion or cation exchange resins. These so-called non-ionic wetting agents, which will be discussed in more detail below, are in fact essentially non-ionic, but it has been shown that they still have a few slightly polar groups which are sufficient to give the wetting agents sufficient strength to hold the mentioned anion or cation exchangers. It is precisely the fact that only a few weakly polar groups are present in these wetting agent molecules that the wetting agents are indeed retained by the exchange resins, but that they are

be released in use at least in such an amount that the wetting agent develop its intended effect can, but on the other hand the levy is so small that actually of a considerable Depot effect can be spoken of. The cloths equipped with these means survive at least twenty normal washing cycles and they are therefore superior to the previously known cleaning wipes.

The adsorbate of wetting agent and exchange resin can can be set in various ways in the cleaning cloth. For example, it is possible to use the cloth from a Manufacture of nonwoven fabric using the dry process is being prepared. In this case, the powdery or bead-like adsorbate can be used in the manufacture of the nonwoven fabric added and by means of the for aie Abbijtiduxi © vlär Facrm required binders are specified. However, since Cleaning cloths usually made from several layers of non-woven fabric consist, it is particularly recommended that the adsorbate of wetting agent and exchange resin between two or to arrange several interconnected, possibly glued, nonwoven layers. It arises on this A voluminous building in which larger amounts of adsorbate, i.e. cleaning agent depot, are accommodated can be. For example, four or five nonwoven layers are stacked and connected to one another, there are two or three intermediate layers that are equipped with adsorbate can, if intended, the upper and lower cover layer of the structure for reasons of grip, to keep the abrasion resistance of adsorbate free.

It has proven to be particularly advantageous if a wetting agent is incorporated into the adsorbate, which selected from the group of alkyl-aryl-polyglycol ethers is. It is preferred to use compounds whose alkyl group has 5-15 carbon atoms and which is arranged directly on the aryl group. The aryl group in turn is via an ether bond connected to the polyglycol framework.

It has also proven to be advantageous if the adsorbate contains an exchange resin which is selected from the group of sulfonates or alkylammonium salts of polystyrene or polystyrene copolymers. It has been found that adsorbates of the mentioned wetting agents and the aforementioned exchange resins lead to particularly vortsilhaf th results.

The production of the cleaning wipes constructed according to the invention is explained in more detail below using a few examples:

Example 1;

1.1 Manufacture of the exchange resin

92 g destabilized styrene and 8 g divinylbenzene are in a known manner in an aqueous, Polyvinyl alcohol-containing dispersion processed into a Perlpolymerisf.t. After completion of the polymerization reaction the resulting product is separated off and dried.

20 g of the dried bead polymer are introduced into 150 ml of concentrated sulfuric acid and 0.2 g of silver sulfate was added as a catalyst. The polymer is with constant stirring at about 100 ° C sulfonated, then the solid is separated off, washed, dried and ground.

1.2 Loading the exchanger resin

The one obtained according to the foregoing formula
Cation exchanger is in 100 ml of a 10 # igen
Dispersed solution of nonyiphenyl polyglycol ether
and left to stand overnight. Then the pest is filtered off, briefly washed with water and
dried. This product is an adsorbate made from a wetting agent and an exchange resin and is suitable for the manufacture of cleaning wipes.

1.3 Manufacture of the cleaning cloth

The adsorbate obtained is used in an amount of

The lieuiiae thus generated wira cautiously πιιτ; one
is another layer of the same textile fiber web and all the layers by means of a Iratex binder or thermoplastic powder in an amount of 10 g / m dry substance interconnected. The result is a cleaning cloth with a considerable depot effect.

Example 2;

2.1 Manufacture of the exchanger casing

° 2 g destabilized styrene and 8 g divinylbenzene
are reacted in a manner known per se in an aqueous dispersion containing polyvinyl alcohol to give a bead polymer. 20 g of this bead polymer are mixed with 50 g of chlorodimethyl ether in ho ml of tetrachlorethylene in the presence of 10 g of zinc chloride
hO-60 ° C chloromethylated within two hours. The product thus obtained is separated off, washed with tetrachlorethylene and dried in vacuo.

For the amination, 20 g of the intermediate product obtained are dispersed in 50 ml of benzene and treated with gaseous trimethylamine for four hours at 30.degree.-35.degree. The beads are then separated off, washed with benzene, dried and finally treated with 5% strength aqueous hydrochloric acid in order to convert the amine into the corresponding ammonium salt.

2.2 Loading the exchange resin

The exchange resin obtained according to the previous section is dissolved in 100 ml of a 1Obigen solution of nonylphenyl polyglycol ether dispersed and left to stand overnight. Then it is filtered off, briefly with water washed and dried.

2.3 Manufacture of the cleaning piece

Foam height is a measure of the amount of cleaning agent dispensed from the depot. After measuring the foam height, pour off the water from each sample, add 50 ml of fresh tap water and shake again. It turns out that the foam height of the tested cloths remains practically unchanged during twenty shaking cycles.

Two exemplary embodiments of the proposed cleaning wipes are explained in more detail below with reference to the accompanying drawings:
It represent

a double-layer cleaning cloth; Fig. 2 is a schematic cross section through a three-layer cleaning cloth with a double depot »

In the exemplary embodiment shown in FIG. 1, the cleaning cloth consists of a lower fleece section and an upper fleece section 2. Both fleece sections are connected to one another, preferably embossed or sealed , in the area of the edge zones 3; 3 *.

Between the two fleece sections 1 and 2, a layer 4 is arranged, which consists of a pearl-shaped adsorbate consists of wetting agent and exchange resin. The adsorbate is not recognizable with the help of one in the drawing Latex adhesive set, which also joins the upper and lower fleece sections together.

The embodiment shown in Figure 2 consists of three fleece sections 5; 6 and 7 · Located between these two depot layers 8 and °> which are both made of pearl
