Method 1: Add vinegar to wash

In addition to salt water, you can also add vinegar when washing your pants for the first time. The effect of vinegar is the same as salt water, which can lock the color.

Method 2: Add salt to the water

The new pants you just bought must be washed before they can be worn, because the pants will definitely have bacteria and dust residues after a series of processes from processing to finished product and on your hands. When washing for the first time, be sure to add salt to the water and soak it for about 12 hours at the same time. In this way, the color of the pants will basically not be obvious after washing.

Method 3: Wash the inside and wash the outside less

After washing the pants for the first time, try to wash the inside and less of the outside every time you wash your pants. Because the outside is the main part of the dyeing, if you wash it too much, it is easy to cause the pants to fade due to friction.

Method 4: Do not expose to the sun

Sun exposure can easily damage the inner structure of the trouser dye. The trousers after exposure will generally be white and shiny, so that the color will easily fade when the next time you go into the water.

Tips: How to wash the sweatpants without fading is the most critical issue, because once the color fades, the pants will lose their original feel and become unsightly. Therefore, we must pay attention to the first cleaning. , Black is a relatively heavy color. In order to prevent this dark color from becoming lighter, we can put a few drops of white vinegar in the basin when cleaning for the first time, so that the acidity is strong and can effectively prevent the loss of pigment. This is also a coup that can solve the problem of how most sweatpants are washed. If you don't pay attention when you wash it for the first time, don't worry, we still have a way to solve the problem of how the sweatpants can't be washed. First of all, when you wash your sweatpants, simply dry them first, and then soak them in warm water for a while. After soaking, you can add a few drops of lemon juice to the water and soak them again for about fifteen minutes. This method is also somewhat similar to the first method. It uses an acidic factor to prevent the loss of pigment, but the lemonade is milder, so it is suitable for pants that have faded a little. This method is also suitable for other faded clothes.
