Definitions

  • Mop head comprising silver containing fibers
  • This invention relates generally to cleaning mops having anti-microbial properties.
  • Such cloth may be made of different kind of fibers, e.g. cotton or wool, synthetic fibers like polyamide or polyester, or mixtures of such natural and synthetic fibers.
  • a common use of said cloth is the use as a head for a cleaning mop. Such mops are commonly used for cleaning purposes of floors and other surfaces.
  • the cloth of the mop head generally has fringes and/or loops of yarns, which are carried on a cloth backing, e.g. a woven fabric.
  • the yarn fibers mentioned above have liquid absorbent characteristics, which make the mop head also useful for removing liquids from surfaces .
  • the mop head Due to the cloth structure of the mop head and the use in combination with water, the mop head constitutes an environment in which bacteria and/or microorganism can proliferate very quickly. This may cause an unpleasant odor of the mop head and the risk to contaminate cleaning surfaces with bacteria and/or microorganism.
  • WO 2004/089180 discloses a mop head, which comprises silver finished fibers.
  • Silver finished means that on the outer surface of the fibers silver is deposited. All silver finished fibers on the mop head mentioned in WO 2004/089180 are fringes or loops. It is known that Silver has inhibiting properties to microorganism, especially to bacteria, yeasts, fungi and similar microbes. It is assumed that the silver ions bind to cell membranes thereby disrupting essential membrane function. This will cause the microorganism to die .
  • Another object of the present invention is to provide a mop head for cleaning purposes that can be stored wet throughout their entire time of use, which almost maintains its long lasting inhibiting effect on bacteria and/or microorganism proliferation. This object is solved by a mop head according to claim 1 of the present invention.

In the prior art, silver is deposited on the outer surface of a fiber only and not dispersed throughout the fiber, as it is according to the present invention.
  • the mop head of the present invention has the advantage that due to the substantially homogeneous dispersion of the silver in the fiber, the silver concentration on the outer surface of the fiber is not altered by ablation over the time of use.
  • the silver concentration on the outer surface of the fiber remains almost unchanged, which upholds the inhibiting effect. Therefore, the silver containing fiber of the present invention will keep a continuous proliferation inhibiting effect.
