1. A method of producing a fiber material or product comprising:
providing a fiber treatment agent of a micro-dispersion water consisting of super-fine noble metal particles dispersed in
water, by combusting a gas mixture comprising oxygen and hydrogen in highly pressurized water; and then heating and melting
a noble metal in the water by the resulting combustion gas, thereby obtaining a micro-dispersion water consisting of super-fine
noble metal particles dispersed therein, wherein the super-fine noble metal particles have a strong hydrophobic property and
have a size on the order of 10−6-10−9 m; and
treating a fiber with the fiber treatment agent, wherein the fiber material or product has the particles externally attached
thereon.
