The first one is to smell
Generally, T-shirts of high-quality T-shirts have no taste. Generally, T-shirts that like to fade are mostly red, black, and purple.
The second kind, look at the workmanship
The quality of the workmanship of a piece of clothing also determines the degree of discoloration of the clothes, and the possibility of discoloration of well-made clothes is smaller.
The third kind, look at the price
The price difference between a fading garment of the same material and a non-fading garment is at least about three yuan. If the price of clothes of the same material really differs a bit, you can consider whether to lose the color.
The fourth, high-temperature method
Whether a piece of clothing fades or not, you can use an electric iron directly. Adjust the temperature to about 180°C and burn it for about 8 seconds. If the clothing does not change color significantly, it means that the bottom of these T-shirts will not fade. You can use it with confidence.
The fifth method, the washing method
This method is also the most stupid and most practical method, which can be distinguished directly. However, considering the occasion and limitations, we still use it in the end.
