Yellowing is the result of long-term accumulation of sweat, oil, and external pollutants. The core causes can be categorized into three categories:
1. Penetration of body secretions
During sleep, sweat and sebum penetrate the core material of the pillow (such as down or cotton fibers). The oils and proteins in these materials oxidize easily, causing the pillow to gradually turn yellow. This is the primary internal cause of yellowing.
2. Adsorption of external pollutants
During daily use, the pillow comes into contact with dust, mite excrement, and airborne pollutants. These external substances adhere to the surface of the pillow or penetrate the core material, causing the color to gradually darken and accelerating the yellowing process.
3. Improper cleaning and maintenance
If the pillow is not cleaned thoroughly (for example, stains are not completely removed during washing) or not aired properly (humid environments can easily breed bacteria and mold), stains will remain and gradually turn yellow. Frequent use of the pillow without timely cleaning can also accelerate yellowing.
