stands for acetate ion in a water ethanol 1 9 solution 2 the ph is adjusted to 8 with an aqueous solution of ammonia 3 the reaction mixture is then purged with argon for 1 hour in order to remove traces of co 2 air 4 the solution is irradiated for 1 hour with a high intensity ultrasonic horn ti horn 20 khz 1 5 kw at 70 efficiency under a flow of argon at 30 u00b0 c 5 the textile is washed thoroughly with water to remove traces of ammonia then further washed with ethanol and dried in air it is also within provision of the invention to prepare the metal solutions as above using metal nitrates or other salts as will be obvious to one skilled in the art as will also be obvious to one skilled in the art the coating process can be accomplished without producing nanoparticles u2018 in house u2019 by adding nanoparticles obtained by some other means to solution and ultrasonically treating as above in steps 2 5 the yield amount of nanoparticles on the textile in this case would be lower but enough to get antibacterial properties a sample coated by the above process with mo was tested for its antibacterial properties with gram positive s aureusa and gram negative e coli cultures antibacterial effects were shown in treated textiles even at a coating concentration of less than 1 for all metal oxides mentioned.
