Discoloration of down jackets is a very common problem and a very troublesome thing, but it depends on how the quality of the down jacket manufacturer you buy is controlled. Let’s take a look at the principle of down jacket discoloration with the editor of Rui Niu!

Discoloration of the partial coating of the down jacket. For example, a brown down jacket has a partial green phenomenon. After testing, it is found that the metal content in the coating is very high, especially the copper content is very high. After copper reacts with oxygen, carbon dioxide and water in the air, it will produce basic copper carbonate, also called patina. Therefore, if the metal content of the coating is high, it will easily lead to oxidation and discoloration of the coating.

The product changes color when it is in the warehouse. For example, the yellowing of black down jackets, after testing, found that the coated fabric contains a large amount of organic volatiles such as toluene and phenolic aldehydes. With the accumulation of organic volatiles, the fabric oxidizes and turns yellow. However, after the down jacket is taken out and washed, it can be changed back to its original color, but after a period of time, yellowing will occur again. But if it is taken for dry cleaning, yellowing will not occur again. This is mainly because the dry cleaning agent reacts with organic volatiles, so it will not turn yellow.

In addition, when the down jacket has coating printing on the surface layer and coating on the reverse side, it may occur during storage. The surface layer dye oxidizes and the reverse coating appears through the fabric, so the coated fabric is also resistant to oxidation and discoloration. Pay attention to it.
