Solid paraffins, which can be amorphous or crystalline, are preferably used as the paraffinic material. Microwaxes and other petroleum products are also suitable. Such _{waxes or paraffins,} when mixed with the copolymer, form a waterproof binder with unusually good adhesive properties.

Abrasion marks, including the folded handle, which are usually less than 6 mm thick, add to their flexibility. Pie underlay and the waterproof binder layer prevent the torn fiber layer from tearing apart during use. Di © pad and the handle enable the housewife to use the scrubbing device without the scouring fibers, in particular t of steel wool or the water to come into contact.

The usefulness of such a scrubbing device strongly depends on the adhesion between the base and the abrasive fiber layer. This bond must be resistant to water and cleaning agents yet be pliable enough that the binder will not peel excessively during use. The waterproof used according to the invention Binders meet these requirements. The abrasive fibers are not even then in an undesirable manner Extent separated from the support when subjected to tensile force, such as during difficult Cleaning operations are carried out on the edges of the pan.

The inventive Yerfahren is other methods for Production of the currently used Scheuerfleckjan, in which common adhesives such as rubber adhesive, in Solvent dissolved adhesives and emulsions are used be considerably superior. By applying the binder in molten form, there is no need for costly recovery systems for solvents, which are also often toxic »Including the expenditure for heating and cooling Excessive drying costs are avoided «By cooling, the binding agent adheres quickly generated on the abrasive fibers, and the process can be accelerated considerably, so that the production capacities can be significantly improved «Since there is no water in the molten binder, metallic Abrasive fibers do not corrode, but keep an appealing, shiny appearance In addition, the simultaneous cooling and pressing of the abrasive fibers η into the waterproof binder creates a binding superior to the application of only one of these measures «

The inventive method not only allows continuous Creation of cut-to-size rub stains,

but also of web-shaped rolls that can optionally be rolled up Rub marks or streaks that work for some uses the cut rub stains under certain circumstances are preferable. The tape or roll-shaped abrasive strips can also be pre-cut or partially pre-cut in order to only separate individual parts Immediately facilitate the joint support of chafing stains held together before use.

The following example describes a method for producing the rub marks according to the invention, which has already been successful to be used. Unless stated otherwise, all quantitative ratios relate to weight data.

example

30 parts of paraffin wax with a melting point of approximately 70 ° C., 30 parts of filtered stabilized rosin ("Staybelite resin" from Hercules Powder Co., Wilmington, Delaware) and 40 parts of an ethylene-vinyl acetate copolymer with an ethylene / vinyl acetate ratio of about 67 ί 33 are mixed with one another and melted at 115 ° C. The melted mixture is applied to a paper base using an application device. The coating weight is regulated so that a crepe-like paper with great strength and a basic weight of about 17 kg per ream, preferably with one

Top coat weight of 20 to 25 kg per layer is coated * Compartment of the coating, a steel wool layer is applied to the coated side of the paper by guiding the coated paper and steel wool over a heated roller. «The heated steel wool embeds itself in the binder and during the subsequent cooling and pressing at 10 ° C, the bonding agent solidifies it firmly with the base *

A 33% aqueous solution of a mixture is then added of potassium and sodium soap with an automatic brushing device The soap is brushed onto the steel wool and is a mixture of equal parts coconut oil and day fatty acid, in which the saponifying alkali metal is a 9 s 1 mixture of potassium and sodium.
