What is the reason why clothes turn yellow?

We often find that some white clothes will turn yellow after wearing for a long time, so many people don’t like to wear pure white clothes, but white clothes are versatile and good-looking, so every girl will have some white clothes, but white clothes are too difficult to maintain, and they will turn yellow after wearing for a long time or being stored for a long time. So, do you know why white clothes turn yellow? What should you do if white clothes turn yellow? Here we will introduce to you the reasons why white clothes turn yellow.

Fluorescence agent weakens

Fluorescent whitening agent is a fluorescent dye, also known as white dye, and is also a complex organic compound. Its characteristic is that it can excite the incident light to produce fluorescence, so that the dyed substance obtains a sparkling effect similar to fluorite, making the substance visible to the naked eye very white, achieving a whitening effect. If the fluorescent agent on white clothes becomes weaker, they will not look so white naturally. White clothes without the fluorescent agent will appear yellowish visually.

Protein stain coagulation

Our clothes will be exposed to many protein stains during the process of wearing and using. If the water temperature is too high during washing, the protein will coagulate on the fabric. If it cannot be completely washed, the protein coagulated on the fabric will oxidize and become more and more yellow over time. So it is important to note that when washing white clothes that are worn close to the skin, try not to use too high a temperature.

Oil residue from the body

Sometimes, we will see serious yellowing under the arms or inside the collar of white clothes. In fact, that is because sometimes, the main reason for the yellowing of white or light-colored clothes is the oil secreted by the human body, especially clothes made of polyester fabrics, which are more prone to yellowing. In addition, there are soap residues left over from washing. If they are not rinsed thoroughly, they will cause large areas of clothes to turn yellow.

The above is an introduction to the reasons why clothes turn yellow. I believe everyone has already understood it. What I also want to tell you is that when washing white clothes, they should be washed separately and not washed together with other clothes, even if they are of similar colors and do not fade. Soak them in clean water for fifteen minutes after washing. Try not to leave foam from soap, laundry detergent, etc. on the clothes. White clothes are very delicate, so please preserve them well.
