Metal zipper with double-side color effect and production method thereof

Abstract

The invention discloses a metal zipper with a double-side color effect and a production method thereof; a zipper teeth base material comprises 63-67% of copper, 33-37% of zinc, other trace metals, and colored layers with two different colors on surfaces and different-thickness organic protective layers coated according to different zipper types. The production method comprises the steps: chain teeth after chemical polishing are colored with a first color; then one face of each tooth is coated with a chemical protective layer with the thickness of 0.02-0.25 mm; and next the other face of each tooth has the color faded by a chemical deplating solution to expose a metal material and then is colored with a second color, and finally the other face is coated with the organic protective layer with the thickness of 0.02-0.25 mm.

Description

technical field [0001] The invention discloses a zipper, in particular a metal zipper with double-sided color effects and a manufacturing method thereof. Background technique [0002] Metal zippers play a pivotal role in the zipper industry. Because of their superior texture and high-grade metallic luster, they are often used in clothes and bags. With the rapid development of the clothing industry, more changes are required on the surface of the zipper teeth to meet the needs of the market. Because the traditional metal zipper chemical plating is difficult to achieve the novel effect of different colors on both sides of the teeth, it cannot meet the current trend of wearing clothes on both sides, and when dealing with chemical plating, it is difficult to color the two sides of the chemically plated chain teeth because of different colors and How to protect the color of one side and remove the technical limitation of the color of the other side makes it impossible to produ...

Problems solved by technology

[0003] Aiming at the above-mentioned disadvantage that one-time electroless plating of metal zippers in the prior art cannot solve the disadvantage that the two sides of the zipper elements are colored in different colors, the present invention provides a brand new metal zipper with double-sided color effects and its manufacturing method. The front side of the plated first color is passivated and protected by chemical agents, and the reverse side is faded with a fading solution to completely expose the original material surface of the chain teeth, then secondary coloring, and finally an organic protective layer
