The plating method using is not common because the types of fibers are limited. Further, the coating method of introducing a copper ion-trapping group has a problem that the metal coating is limited to copper or its compound and the adhesion strength of the metal coating is not always sufficient. Although the adhesion strength of the metal coating can be generally increased by roughening the fibers by treating them with an alkali, a sufficient effect cannot be obtained unless the degree of roughening and the state of the metal coating are appropriate. Moreover, when the metal-coated fiber is used for clothing or the like, it is necessary to withstand severe use conditions such as washing and abrasion. Further, from the viewpoint of conductivity, even if the metal coating is partially peeled off, a disconnection state is caused. Therefore, the metal coating is required to have a highly reliable adhesion strength. Further, metal-coated fibers, especially silver-coated fibers, have a problem that surface corrosion and discoloration occur in the atmosphere due to oxides, detergents, and the like.

It is called yuzu skin or satin skin. When the layer thickness of the metal coating is approximately several hundreds of nanometers (nm) or less, the metal coating having orange peel is roughened to the back side of the coating, and the surface of the substrate fiber is a metal in this roughened state.

The amount of the fluorine compound coating in the metal-coated fiber body is 5% by weight or less, preferably 0.01 to 5% by weight. Excellent water repellency is obtained by this fluorine compound coating. To have long-lasting water repellency, the amount of fluorine compound coating is 0.5% by weight
The above is preferable. Even if the coating amount exceeds 5% by weight, the water repellency does not change significantly, so the coating amount is 5% by weight.

For example, a solution containing the above compound is applied to a metal-coated surface, or a metal-coated fiber body is dipped in these solutions to adhere a fluorine compound solution to the metal-coated surface, which is dried and heat-treated to give a fluorine-based surface active agent. A fluorine compound coating is formed on the surface of the metal coating by reacting the agent or by hydrolyzing the alkoxysilicone.

できる。The metal-coated fiber body of the present invention has a fluorine-based compound coating on its surface, which serves as a protective layer for the underlying metal coating, so that the corrosion resistance is improved. Specifically, for example, when the metal-coated fiber body is washed with a chlorine-based cleaning agent, the surface coating prevents penetration of the chlorine-based cleaning agent, and thus the corrosion resistance to the chlorine-based cleaning agent is excellent. Also,
It also has excellent corrosion resistance against sulfide reactions caused by sulfides contained in dust and sweat, and corrosion caused by oxidation reactions in air. Furthermore, since the underlying metal coating is not exposed to the outside, there is almost no irritation to the skin and there is no risk of metal allergy or the like. Further, since these fluorine compound coatings have high transparency, the color tone of the underlying metal coating appears on the coating surface under an appropriate film thickness. Therefore, by providing the white conductive metal coating, it is possible to obtain a white conductive fiber body which is excellent in corrosion resistance and does not cause metal allergy.

される。The metal-coated fiber body of the present invention includes a surface of a fluorine-based compound coating which is further surface-treated. As the surface treatment, rust prevention treatment with paraffin or wax or oil treatment (oiling) can be applied.
It should be noted that this rust-prevention treatment can prevent a decrease in whiteness over time and a decrease in adhesion (peel strength). Also,
The oil treatment improves the slipperiness of the surface of the fibrous body. This oil treatment improves the slippage of the fibrous body when it is processed by a loom or a knitting machine, and thus protects the adhesion of the metal coating. When the metal coated fiber body is actually used,
When subjected to physical forces such as friction, shearing force, and bending, the metal coating is peeled off or missing depending on its strength and frequency. Although their degree is directly based on the adhesion strength between the metal coating and the fibrous body, the above surface treatment buffers friction, shearing force, etc., and consequently prevents the metal coating from peeling.

The heat treatment atmosphere may be air, but in order to prevent discoloration due to the oxidation of the metal coating, it is preferable to perform the heat treatment under an inert atmosphere such as nitrogen or argon. In addition, metal coating (plating), put the fibrous body that has been subjected to heat treatment again in the tank of the plating process, circulate the fluorine-containing compound solution to make contact, then introduce pressurized steam, and perform drying and heat treatment. Thus, the fluorine compound can be uniformly coated on the upper layer of the metal coating.
