Metal zippers are widely used as clothing fasteners, which can be made into open-end zippers, double-open-end zippers, closed-end zippers, "O" double-closed zippers, and "X" double-closed zippers. Metal zippers are very popular in the market, but because of their material characteristics, they cause some defects. When using metal zippers, you need to understand its characteristics and avoid these defects.

Metal zippers are exposed to the air for a long time, and a metal oxide layer will be formed on the surface. Wiping the surface with paper will turn black. Occasionally, traces of sprockets are attached to the parts of the jacket that are close to the sprockets, which are often copper primary color tooth marks. However, the copper products are exposed to the air for a long time, and the fastener elements will slightly yellow due to oxidation. Therefore, this product should be stored in a humid environment.

When using a Metal Zipper, because the surface is waxed, if the paper is not placed on the middle of the chain elements and cloth during ironing, the cloth will be stained with wax. During the production process, white copper products are liable to leave slight black tooth marks on the fabric.

When the metal zipper round and square teeth are made into a double-pull product, due to the guiding problem in one direction, the zipper has a large resistance when it is pulled, so the phenomenon of unsmoothing will occur. Therefore, when recommending such products to consumers, pay attention to communication instructions.

Due to oxidation, the color of the surface of the tape may be damaged, so the color will be darker than before the oxidation. In addition, the color of the chain element will also have a color difference due to different batches, which is generally between 3-4.

Whether it's a Plastic Zipper, Nylon Zipper or Brass Zipper, small clothing fasteners also need maintenance to ensure that they can be used normally.
