Most swimsuit fabrics are made of nylon, also known as nylon fabric. Generally, swimsuit fabrics are composed of 80% nylon, 20% spandex, or 82% nylon, 18% spandex. You can see that many famous swimsuits are made of these two materials, and in the swimsuit industry, nylon fabric is the best. We won't delve into the differences between nylon and polyester one by one here, because today we are discussing the issue of yellowing in swimsuits.

Many consumers find that their swimsuits turn yellow during use. I think many people's first thought is that the quality of swimsuits is not good. So do you think this is caused by a quality issue? In fact, this has little to do with the quality of swimsuits. Firstly, most brands in the market use nylon+spandex, and regardless of the brand, light colored swimsuits are likely to experience yellowing.

Friends whose swimsuits turn yellow, please raise your hand and come over to see if you have been hit by the following points

1. Incorrect washing and care method: Use high-strength detergent to clean swimsuits

2. Sweat and oil stains, apply sunscreen around swimsuits

3. The temperature in the place where swimsuits are stored is too high (swimsuits are exposed to sunlight for a long time, swimsuits are placed in the rear trunk of the car, etc.)

Reasons for yellowing of nylon fabrics

1. Alkaline agents and phenols cause yellowing of fibers.

2. Nitrogen oxides in the air cause yellowing of nylon fabrics, including CO, CO2, NO, NO2, etc.

3. Light and heat cause fiber breakage and decomposition of nylon fabrics, resulting in yellowing.
