         10 ) A fabric made according to  claim 3  wherein the ethyl acetate is present in an amount of about 10 percent of the water by volume. 
     
     
         11 ) A process for producing a MRSA-resistant fabric that retains 4-7 log reduction in MRSA growth thereon after up to twenty-five launderings, comprising the steps of:
 a) immersing the fabric in a solution of glyxol, eugenol and water;   b) squeezing the solution out of the fabric   c) curing the wetted fabric under heat; and   d) drying the cured fabric.
