Newly purchased textiles and clothing should be washed first to reduce the impact of fabric acidity or color fading on the human body.
For products with colors or bright colors, white cloth can be used to rub against the product. If the color fading is obvious, or if the color fading is severe when washing after buying it, it may be due to the use of inferior dyeing agents, which have poor color fastness and are not recommended for use.
