There are many zippers used in life, and their materials are different, such as metal, nylon, plastic, resin zippers, etc. Metal zipper is a kind of zipper, which refers to the zipper whose microphone teeth are made of copper, cupronickel or aluminum material. Compared with nylon zipper and resin zipper, it is stronger and is mostly used on jeans, jackets and backpacks. Many products require maintenance, and metal zippers will oxidize and rust after a long time of use. So how to prevent metal zippers from rusting? Next, let’s learn about it with you!
1. Avoid contact with the rubber band: The rubber band itself contains sulfide. When the metal zipper is bundled with the rubber band, the metal teeth will be vulcanized (blackened).
2. Wash and dry in time after washing: Because the dyes or residual chemicals in the fabric have redox reactions with metal parts, it may cause discoloration of metal parts. Yifeng zipper manufacturers recommend that in order to reduce the degree of discoloration, zipper metal products should not be sealed in cellophane or thick paper bags.
3. Avoid contact with wet environment: For metal zippers made of copper alloys (white copper, red copper, brass), when operating on metal products or wool products, some of the teeth of the metal zipper will change due to metal oxidation. black phenomenon. This is due to the leather curing agent for making leather and the processing bleaching agent on woolen products, etc., when the product remains on the product during the treatment process, the gas smell of the product causes the discoloration of the metal zipper.
Fourth, avoid contact with air: If the metal zipper does not rust, it must be isolated from the air; apply some sewing machine oil or lubricating oil on the metal zipper and zipper head, not too much, apply it on the surface of the metal, be sure To apply it all over to form a layer of oil film, the zipper will not rust. As for the metal zipper head, wrap it completely with plastic wrap (this method can also be used for other metal parts), so that it cannot touch the air, close the zipper and then store it. If possible, put a plastic bag on it and tie the plastic bag tightly. Keep contact with air to a minimum and store in a dry, cool, dust-free cabinet.
