Something About the Fade Color of Clothes

The fiber itself is colorless and the color is dyed at a later stage. In the past, dyes extracted from plants such as turmeric, indigo, limited in color, and easy to faded in use. Right now, the synthetic dyes is used, such as azo dyes, need to be added when dyeing. The reactants are saturated and not easy to react with the outside, much stronger than plant dyes.

Due to material and technological problems, fade color has always been a headache in the textile industry. One of the main reasons is that the dye used on the clothes is not of good enough quality, or the post-processing of the garment is not done well after dyeing. This will lead to color difference and faded clothing after a period of friction, sun or washing.

In addition, we need to note that no matter how good the dye can not withstand ultraviolet radiation, long-term sunshine will make all colors fade. Faded is a natural reaction, the molecular bonds of the dye are interrupted by ultraviolet high energy to cause a chemical reaction.

The fade color of the clothes is inevitable, and the way and reason of the fade color are also diverse, so what are the laws of the fade color of the clothes?
