Method for preventing zipper discoloration

The chemical properties of the copper alloy in the metal zipper are chemical reaction and easy discoloration when encountering acid, alkali, oxidant or reductant. Zippers may discolor when chemical residues on the clothing material chemically react with the fastener elements, slider or open end of the metal zipper.

First, the bungee banding metal zipper discoloration reasons: rubber band itself contains sulfide, bungee banding metal zipper, the metal Splinter will produce vulcanization (darkening). Examples of Chemical Reactions: Excessive Sulfide or HS2 Gas Conditions → Black [CuS] III. Causes of discoloration due to contact with acidic or chromium compounds. Examples of chemical reactions are acidic compounds and chromium compounds [Cr2O3] → black [CuO, red [CuO2] or blue [CuSO4]. Four, hanging electric zipper discoloration reasons: Although the zipper head hanging anti-rust treatment has been done in advance, but the oxidation is a metal property, in order to reduce discoloration and surface scraping flowers, please zipper head wrapped with copy paper. Examples of chemical reactions: wet weather or steam → blue [Cu (OH) 2]. 

1, to avoid a long time ironing clothes or long-term sealed packaging in plastic bags, because the clothing residual chemicals in the high temperature, high humidity conditions easier with the metal zipper teeth, pull the head, the tail part of the chemical reaction Cause discoloration If necessary, use moisture-proof paper, moisture-proof metal zipper to reduce the degree of chemical reaction. 

2, to avoid the metal zipper and acidic, alkaline, oxidant or reductant contact. 

3, the correct method of washing: before washing or drying into the dryer, the zipper closed, the slider fixed. If you open the washing, the top of the top will damage the fabric, and the tape will shrink. Alkaline detergents or chlorinated bleaches coat the metal zipper with paraffin or oil film.

As mentioned above, the zipper also needs our careful maintenance.
