| Precautions for using metal zipper | | | · | chemical properties of copper alloy (discoloration principle of metal zipper teeth) | | | the chemical property of copper alloy is chemical reaction when it meets acid, alkali, oxidant or reducing agent, which is easy to change color. The zipper may change color when chemical agents left on the dress material and chain teeth, pullers or open-end parts of the metal zipper are reflected. This kind of chemical reflection is relatively easy to occur under high temperature conditions. This is not a zipper quality problem. | | · | precautions when using metal zipper for clothes of different textures | | | woolen sweater | | | the bleaching of woolen sweater fabrics usually adopts the following methods: | | | 1. Treat with acid Bleacher (H2O2) or reductive Bleacher (sulfite).
2. In the post-treatment process of bleaching, such as anti-shrinkage treatment or bleaching treatment, if the water washing and neutralization treatment are insufficient, gases such as L2 or S2 will be generated. These bodies are exposed to high temperature (steam ironing) it is easy to react with metal. Therefore, after bleaching, please use a cloth that is clean enough.
3. As the fabric is pressed and packaged immediately after being ironed by steam, the accessories (teeth, pullers, upper and lower stops, etc.) containing copper alloy in metal zipper react with reagent or gas, which is easy to change color. Therefore, please fully cool the products after steam ironing before packaging. | | | Ordinary clothing products | | | because the post-cleaning treatment of dyeing processing is insufficient, the acidic compounds remaining on the dyed fabric are easy to react with the metal zipper and stain the fabric. Therefore, use a dress material that completely removes the oxidant (neutralizes) or is thoroughly cleaned. When purchasing metal zippers, special purposes and special requirements should be indicated, such as ordinary washing and acid enzyme washing. |
