Definitions

  • This invention relates to the manufacture of artificial sponges and more particularly to the manufacture of sponges having improved resistance to bacteria and fungi.
  • the artificial sponge of regenerated cellulose is treated with a reaction product of Water soluble polyacrylic acids and quaternary ammonium compounds of high molecular weight.
  • the sponges treated in this manner are indeed highly resistant to attack by bacteria and fungi, but they have the disadvantage of losing part of their resiliency during use.
  • a process has now been found for the treatment of artificial sponges of regenerated cellulose as a result of which the sponges are likewise not attacked by bacteria and fungi.
  • the sponges treated according to the process of the invention have the additional advantage that they retain their resiliency after prolonged use.
  • An object of this invention is to provide an improved process for treating sponges.
  • Another object is to provide an artificial sponge having increased resistance to bacteria and fungi attack as well as good resiliency.
  • an alkali metal salt of carboxy methyl cellulose is used according to the invention, sodium carboxy methyl cellulose is preferred.
  • Quaternary ammonium compounds with a germicidal action suitable for use in the invention include the following: cetyl trimethyl ammonium bromide, cetyl dimethyl ethyl ammonium bromide, stearyl trimethyl ammonium bromide, lauryl triethyl ammonium chloride, octadecenyl dimethyl ethyl ammonium bromide, octadecyl dimethyl benzyl ammonium bromide, cetyl dimethyl benzyl ammonium chloride, lauryl dimethyl benzyl ammonium chloride, di-isobutyl cresoxy ethoxy ethyl dimethyl benzyl ammonium chloride and di-isobutyl phenoxy ethoxy ethyl dimethyl benzyl ammonium chloride.
  • EXAMPLE I Twenty-five artificial sponges produced from viscose were immediately after their production centrifuged. The centrifuged sponges were first treated with an aqueous solution containing 1.0% by weight sodium carboxy methyl cellulose with a viscosity of about four centipoises at 20 C.
  • the sponges were centrifuged and thereafter treated with an aqueous solution containing 1.0% by weight lauryl triethyl ammonium chloride. The sponges were then rinsed with water and finally again centrifuged.
  • the twenty-five treated sponges were used with twenty-five untreated sponges for an eightmonth period of time for Washing automobiles. Thereafter the sponges were judged on the following points: smell, resilience, signs of attack and appearance. The results are as shown in Table I.
  • the treated sponges were used for washing automobiles for eight months; at the same time, twenty-five untreated sponges were used for washing cars for comparative purposes.
  • An artificial regenerated cellulose sponge containing a material selected from the group consisting of reaction products of cal-boxy methyl cellulose and a quaternary ammonium compound of high molecular Weight and reaction products of an alkali metal salt of carboxy methyl cellulose and a quaternary ammonium compound of high molecular Weight.
