DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a mop head for the wet or damp cleaning of floors consisting of an elongate textile support layer with holder insertion pockets arranged on top and at either end thereof and material arranged underneath in the form of tufts, fringes, loops, sponge cloth strips or the like for taking up dirt and moisture.
Mops of the type in question are used for cleaning floors. To this end, the mop head is fitted onto holders, the ends of the holders being inserted into the holder insertion pockets. The holders comprise a handle so that the holders with the mop head fitted thereto can be conveniently guided across the floors to be cleaned.
RELATED ART
One mop head of the type in question, in which the holder insertion pockets can be formed from a sheet-form textile material, is known from DE-PS 3 809 279. However, in this mop head, the holder can only be inserted into the holder insertion pockets if they are open. However, since the mop heads are frequently squeezed out in mangles to remove water and are also regularly washed and cleaned in washing machines, the pockets do not stand open, but instead lie flat on the textile support layer. To be able to insert the holder, the pockets first have to be opened by hand.
Another mop head, in which the holder insertion pockets are made of plastic, is known from DE-OS 37 37 414. This mop head is also attended by the disadvantages mentioned above.
To remedy the situation, other known mop heads comprise reinforcements in the form of concealed stiff plastic strips or the like in the region of the pocket openings. These reinforcements are sewn into the holder insertion pockets.
However, reinforcements of the type in question have a number of disadvantages. Firstly, they present problems when the mop heads are squeezed out in mangles because the mop heads frequently jam between the rollers of the mangle. In addition, where the reinforcing strips are made of plastic, they are often destroyed so that they are unable to perform their function of keeping the insertion pockets open. The known proposals also have disadvantages in regard to the cleaning, i.e. washing, of the mop heads. The stiffened regions are obstacles to the fulling process when the mop heads are washed in washing machines. In addition, the stiff reinforcements and pockets rub on the textile support layer during washing and thus lead to premature destruction of the mop head. The weight of the mop heads to be washed is also increased by the reinforcements because the holder insertion pockets are now heavier. Finally, when the mop heads are dried in dryers, the reinforcements in the form of plastic strips are in danger of deforming under the effect of the relatively high drying temperatures and so are no longer able to perform their function.
DE-PS 31 24 292 describes a swellable twisted combination yarn which is used, for example, in the manufacture of disposable diapers.
The object of the present invention was to provide a solution with which the pockets could be kept open without impairing the other performance properties of a mop head.
In a mop head consisting of an elongate textile support layer with holder insert pockets arranged on the top at both ends thereof and material arranged underneath in the form of tufts, fringes, loops, sponge cloth, strips or the like, the solution provided by the invention is characterized in that the holder insertion pockets comprise 0.5 to 10 mm thick strips of a water-absorbing and swellable material, preferably cellulose fleece, in the region of the pocket openings.
The mop heads come into contact with cleaning liquid in the wet and damp wiping of floors. The cleaning liquid is absorbed by the strips of water-absorbing and/or swellable material, which are dry before use, so that the strips undergo an increase in volume and expand. In this way, the holder insertion pockets are opened or kept open. However, the solution according to the invention, by which the insertion pockets are kept open, is not attended by any of the disadvantage
