Definitions

  • the present invention relates to an artificial mopping/wiping sponge having an improved network texture formed by intertwined curled yarns which together defines latticework of polygonal lattices that can increase the effective contacting area, and therefore the rubbing effect between the sponge and the wiped object, thereby enhancing the wiping efficiency.
  • a soft, porous and absorbent mass which can be natural material, for example, a piece of natural sponge or a so-called "sponge-fruit mop" [a fibrous mopping mass made of a sponge fruit (sponge gourd)], or synthetic material, such as an artificial sponge.
  • an artificial sponge (10) which can be provided with a tying lace (11), is formed by drawing and spinning a plastic material into straight yarns (31) and knitting them into latticeworks (30) of polygonal (preferably hexagonal) lattices which are juxtaposed and superposed to form a three dimensional network. Thanks to the artificial yarn which has a far stronger resistance to wear than the natural material, the durability of the artificial sponge is much improved.
  • the disadvantage of the known artificial mopping/wiping sponge consists in its relatively poor rubbing effect.
  • the latticework (30) is repeatedly rubbed against a surface. Since each lattice comprises a hexagonal loop of smooth (here the term “smooth” means “uncurled") yarn, which tends to "slip" on a surface instead of rubbing heavily thereon, the effort applied by the hand cannot be efficiently transformed into the friction between the artificial sponge and the wiped object. As a result, the mopping efficiency is altogether unsatisfactory.
  • the hexagonal lattices with their smooth yarns that define the hexagonal loops, can be easily compressed to a much smaller volume, the effective, contacting area between the sponge and the wiped object is greatly reduced when a force is applied, the insufficient wiping efficiency is further worsened.
  • the loop is formed by curled yarns to give a relatively "rugged" lattice which on the one hand greatly increase the friction between the sponge and a wiped object, and on the other hand, greatly reduces the compressibility of the lattices, and therefore of the sponge under a pressure, thus largely increasing the wiping efficiency.
  • the loops (21) are formed by curled yarns (21), which make the latticework less compressible.
  • curled yarns (21) make the latticework less compressible.
  • the force applied by the hand can be more efficiently applied to the wiped tablewares. Since the sponge is not so much compressed under the applied force, the effective area is less reduced.
  • the curled yarns of the latticework provide a far higher friction than the conventional uncurled yarns. accordingly the rubbing effect is greatly improved.
  • the curled texture can be easily obtained by a secondary treatment on the known sponges of latticework texture with uncurled yarns.
  • the secondary treatment is performed by putting artificial sponges of the conventional latticework texture in a container, and then the texture is subject to a warming and a pressurizing process so that the yarns become curled. Since the details of the secondary treatment is not the main feature of this invention, further description can be omitted.
  • a sponge in accordance with the present invention comprises a sheet, or more preferably a plurality of sheets, comprising a latticework structure of substantially polygonal loops defined by a plurality of interconnected filaments of plastics material.
  • the sheet or sheets are preferably gathered together to form a dense mass by one or more strings or ties drawn tightly around the sponge.
  • the frictional or abrasive action of the sponge is improved by the fact that the filaments, i.e. the elements defining the polygons, are curly, that is to say non-linear, e.g. are of crinkly or crimped shape.
  • the sponge in accordance with the invention may be used not only as a mop for mopping/wiping purposes but can also be used as a bathroom sponge.
