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 swimwear ingredients are made of these two materials, and in the swimwear industry, nylon fabric is the best. We won't discuss the difference between nylon and polyester one by one here, because today we are discussing the issue of yellowing of swimsuits.
Many consumers have noticed yellowing in their swimsuits during use. I think many people's first thought is' the quality of swimsuits is not good '. So do you think this is caused by quality issues? Actually, 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 with yellow swimsuits, please raise your hand and come over to see if you have been hit by the following points
1. Wrong washing and care method: use high-strength detergent to clean swimsuits
2. Sweat and oil stains, apply sunscreen around swimsuits
3. The temperature of the storage area for swimsuits is too high (swimsuits are exposed to the sun for a long time, swimsuits are placed in the rear trunk of the car, etc.)
Reasons for yellowing of nylon fabrics
1. Yellowing caused by alkalis and phenols on 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.
There is nothing that has a permanent shelf life. Products with usability such as swimsuits cannot avoid wear and tear, and even if they have not been used at all, swimsuits may turn yellow over a long period of time. In order to extend the service life as much as possible, please take care of your swimsuit, rinse it with water, and air it in a cool place.
