Abstract

A method for subjecting garment accessories to a surface electrolytic treatment provides various metallic colors to metallic garment accessories in a cost effective manner. The method can provide a first metallic color on one side of outer surface of the garment accessory and provide a second metallic color on the other side of the outer surface, by placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory.

First claim

1 . A method for subjecting garment accessories to a surface electrolytic treatment, comprising placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory to provide at least a part of the outer surface of the garment accessory with a metallic color(s) different from the color of the outer surface.

2 . The method according to claim 1 , wherein the metallic color comprises a first metallic color and a second metallic color, the first metallic color being provided on one side of the outer surface of the garment accessory while at the same time providing the second metallic color on the other side of the outer surface.

3 . The method according to claim 2 , wherein the metallic color comprises a third metallic color, the third metallic color being provided between the first metallic color and the second metallic color on the outer surface of the garment accessory.

4 . The method of claim 2 , further comprising the step of controlling the posture of the garment accessory such that the one side of the outer surface of the garment accessory faces the anode and the other side faces the cathode during passing electric current through the electrolytic solution.

5 . The method according to claim 1 , further comprising the step of polishing at least a part of the outer surface of the garment accessory during passing electric current through the electrolytic solution.

6 . The method according to claim 1 , wherein the one or more garment accessories are selected from the group consisting of elements for slide fasteners, lower stops, upper stops, sliders, pull tabs; buttons; mounting members for buttons; parts for buttons; eyelets; and hook eyes.

7 . A metallic garment accessory comprising an outer surface having one side and the other side, the one side of the outer surface having a first metallic color and the other side of the outer surface having a second metallic color, the second metallic color being different from the first metallic color, wherein the first and second metallic colors are provided by a bipolar phenomenon, the bipolar phenomenon being generated on the garment accessory by passing electric current through an electrolytic solution in which the garment accessory is placed.

8 . The garment accessory according to claim 7 , wherein a third metallic color is provided between the first metallic color and the second metallic color on the outer surface of the garment accessory.

9 . The garment accessory according to claim 7 , wherein it is selected from the group consisting of a set of elements for a slide fastener, a lower stop, an upper stop, a slider, a pull tab; a button; a mounting member for a button; a part for a button; an eyelet; and a hook eye.

10 . A method for producing a garment accessory(s) having a metallic color on at least a part of its outer surface, the metallic color being different from the color of the outer surface of the garment accessory(s), the method comprising the steps of placing one or more garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, and passing electric current through the electrolytic solution to generate a bipolar phenomenon on the garment accessories.

11 . The method according to claim 10 , wherein the metallic color comprises a first metallic color and a second metallic color, the first metallic color being provided on one side of the outer surface of the garment accessory while at the same time providing the second metallic color on the other side of the outer surface.

12 . The method according to claim 11 , wherein the metallic color comprises a third metallic color, the third metallic color being provided between the first metallic color and the second metallic color on the outer surface of the garment accessory.

13 . The method according to claim 11 , further comprising the step of controlling the posture of the garment accessory such that the one side of the outer surface of the garment accessory faces the anode and the other side faces the cathode during passing electric current through the electrolytic solution.

14 . The method according to claim 10 , further comprising the step of polishing at least a part of the outer surface of the garment accessory during passing electric current through the electrolytic solution.

15 . The method according to claim 10 , wherein the one or more garment accessories are selected from the group consisting of elements for slide fasteners, lower stops, upper stops, sliders, pull tabs; buttons; mounting members for buttons; parts for buttons; eyelets; and hook eyes.
