Why does underwear turn yellow after washing and drying? There are thousands of types of underwear for women, but underwear is different from ordinary clothing. The material fibers are relatively soft, thin, and delicate. The most ideal washing method for underwear is to use "warm water" and "neutral detergent", as well as lightly press "hand wash", carefully read the label of the underwear. The different patterns on the label represent different washing and maintenance methods.

Attention should also be paid to the following points when cleaning and maintaining underwear:

1. Before cleaning underwear, first check the underwear. If there are any loose threads, they must be sewn together, and the back hook must be hooked and the shoulder straps fastened to avoid hooking onto the fabric during the washing process.

2. When washing, neutral detergent should be dissolved in warm water at 30 ℃ -40 ℃ before putting down the clothes. After soaking for a while, gently tap with your hands and do not wash vigorously to avoid wearing down the fabric.

3. Thoroughly rinse the detergent when cleaning.

4. Do not use fabric softener after washing to avoid damaging the elastic fibers of the underwear.

5. After washing, you cannot wring it out by hand. You can only wrap it in a dry towel and squeeze it with your hand to let the towel absorb the moisture. Then, flatten the underwear to its original shape. If it is chest circumference, you should tidy up the cup shape.

6. Sunlight can easily cause clothing to deteriorate and fade, so underwear can only be dried in a cool and ventilated place.

7. Wet bras should be hung at the point between the cups, and avoid hanging the shoulder straps because the weight of moisture can elongate the straps

When storing, make sure that the underwear has been completely dried, or put some desiccants in the wardrobe to absorb moisture. Do not use sealed plastic bags to store underwear, as it is prone to mold growth. When storing underwear, be sure to keep it away from insect repellents, as insect repellents are the nemesis of silk and elastic fabrics. Once in contact, they will become brittle, loose, and lose their elasticity.
