The invention concerns a floor-cleaning mop head having an oblong textile base fabric with, attached to the top at both ends, slide-in pockets for the head-holder and, attached underneath, material designed to collect moisture and dirt in the form of hair tufts, fringes, loops, foam-rubber strips, etc. The aim of the invention is to provide a disign which ensures that the pockets on top of the mop head remain open even after the mop head has been washed several times, without the other useful characteristics of the mop being affected. This is achieved by virtue of the fact that the oblong base fabric (2) consists, at least in the zone of the slide-in pockets (3), of a material which is more highly heat-shrinking than the textile material of which the pockets (3) are made.
