What causes underwear to turn black?

The darkening of underwear may be caused by the body's high amount of sweat, or it may be caused by improper washing of the underwear. In addition, the fading of the underwear cannot be ruled out.

1. The body sweats a lot: Underwear is a common clothing for women. When choosing underwear, people will choose underwear made of high-quality materials. First of all, it will be more comfortable to wear and will not easily cause pressure on the breast tissue, which is conducive to better circulation of the breast tissue. The problem of underwear turning black may be that the material of the underwear is relatively poor. Especially for people who sweat a lot, often wearing underwear with poor breathability will affect the body's normal perspiration, which will cause the underwear to turn black.

2. Inadequate cleaning of underwear: The darkening of underwear may also be caused by inadequate cleaning of the underwear. When washing underwear, professional underwear washing utensils are not used to wash the underwear separately, but the underwear is washed together with other dark-colored clothes. This can easily cause the cotton underwear to be stained with other colors, which will cause the underwear to turn black.

3. Underwear fading: The darkening of underwear may also be caused by factors that cause the underwear to fade. Long-term soaking in laundry detergent will cause the color of the underwear to fade, which will cause the color of the underwear to change and affect the beauty of the color of the underwear.
