WIPO Patent Application WO/2003/033809

Kind Code:

A1

Abstract:

A fiber treating agent which comprises an aqueous dispersion having an ultra−fine powder of a noble metal which comprises water and, dispersed therein, an ultra−fine powder of a noble metal. The aqueous dispersion having an ultra−fine powder of a noble metal is prepared by a method comprising combusting a mixed gas of oxygen and hydrogen in a high pressurized water, and heating a noble metal material with the resultant combustion gas, to thereby form the objective dispersion. The treatment of a fiber product with the fiber treating agent allows the production of a high functional fiber product such as a clothing being excellent in the function to promote health and&sol or to improve personal cleanliness.
