Metal zipper and production method thereof

Abstract

The invention provides a metal zipper and a production method thereof, and relates to the field of zippers. The invention aims to provide a metal zipper which can be printed with rich and colorful patterns by a heat transfer print process. The metal zipper comprises zipper cloth and metal teeth, and is characterized in that a metal lacquer protective film covers the metal teeth and consists of mixed liquor of gloss oil H-100A and a thinner. The invention also provides a method for producing the metal zipper which can be printed with the patterns. The method comprises the following steps of: coating the mixed liquor of the gloss oil H-100A and the thinner on the surfaces of the metal teeth of the zipper and drying; and heating and pressurizing by a heat transfer print machine, so that the patterns which are printed on a transfer print film in advance are transferred to the surfaces of the metal teeth of the zipper. By the metal zipper, the defects of monotonous color, high possibility of corrosion, wear intolerance, coarse tooth surfaces, non-flexible opening and closing and the like in the conventional metal zipper are overcome, and the decorative function of the zipper is added on the premise of ensuring the performance of the zipper, so the metal zipper can be widely applied to articles of clothes, bags and suitcases and the like.

Description

technical field

[0001] The invention relates to the field of zippers, in particular to a metal zipper capable of printing patterns by a thermal transfer printing process and a production method thereof. Background technique

[0002] Metal zippers are widely used in clothing, luggage and other items because of their strong and durable characteristics. However, compared with resin and nylon zippers, metal zippers have some problems, such as monotonous color, easy to corrode and rust, and rough tooth surface. , opening and closing are not very flexible, etc., so it limits its scope of use on a large length. The existing surface treatment methods of metal zippers mostly adopt the methods of electroless copper deposition and electroplating treatment, and the surface treatment effect is relatively simple. With the improvement of people's living standards, our demand for metal zippers is not only functional, but also more colorful in appearance. For example, fashion designers oft...
