aforementioned antimicrobial or chemical detoxification properties. The monomer may be a
carboxylic acid which is ultimately oxidized to a regenerable percarboxylic acid that provides the
antimicrobial or detoxifying properties. This appealed subject matter is adequately represented
by independent claims 23 and 34 which read as follows:
23. An antimicrobial fabric produced in accordance with a method comprising the steps
of:
treating a fabric with ozone to form peroxide groups on the fabric;
decomposing the peroxide groups with an iron catalyst to form oxygen radicals; and
grafting a polymerizable monomer to the oxygen radicals on the fabric surface, wherein
the grafted fabric comprises a disinfectant that is the polymerizable monomer or a derivative of
the polymerizable monomer.
34. A protective fabric for protection against chemicals produced in accordance with a
method comprising the steps of:
treating a fabric with ozone to form peroxide groups on the fabric;
decomposing the peroxide groups with an iron catalyst to form oxygen radicals;
grafting a carboxylic acid to the oxygen radicals on the fabric surface; and
oxidizing the carboxylic acid to a regenerable percarboxylic acid, wherein the
percarboxylic acid is covalently bonded to the fabric to provide the protection against chemicals.
The reference set forth below is relied upon by the examiner as evidence of anticipation
and obviousness.
