  • Patent number: 5680667
    Abstract: A floor-cleaning mop head includes 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, and so forth. The oblong base fabric consists, at least in the zone of the slide-in pockets, of a material which is more highly heat-shrinking than the textile material of which the pockets are made, in order to ensure that the pockets on top of mop remain open even after repeated washing of the mop head, without effecting other useful characteristics of the mop.
