What to do if black sweatpants turn red

People may find such a situation in daily life, that is, their black sports pants will turn red. The main reason for this situation is probably because they are stored in a damp and dark place for a long time, and some joints in the dyeing process of the pants do not meet the requirements. When this happens, people need to take some measures to remedy the situation. Here is a detailed introduction on what to do when black sweatpants turn red.

Reasons why black pants turn red

Black clothes turn red because some links in the dyeing process do not meet the standards. Overall, the color fastness is not good enough. One point is that after dyeing, the clothes are "resistant to light, acid and alkali" because we wear clothes, sweat, have different acidity and alkali caused by different environments, and are often exposed to the sun. Therefore, insufficient dye fastness of clothing will cause black clothing to fade or change color for various reasons.

Potassium permanganate and acetic acid recovery method

First dissolve a small amount of potassium permanganate in water, put the clothes that need to be restored into it until they are fully soaked, and after about 10-20 minutes, the clothes will turn dark red. After washing the clothes with clean water, put them into acetic acid dissolved in water, the clothes will slowly turn from dark red to their original color, and the original red will disappear.

Salt water soak recovery method

To wash clothes that are easy to fade, first soak the clothes in salt water for about 30 minutes, then rinse with clean water, and then wash with normal washing methods. Turn the clothes over when drying. This will prevent your clothes from fading, especially black or red clothes.

Other ways to restore black pants to red

If it is cotton, you can add a little beer to the water to rinse it. First, fill half a basin with water, then pour half of the beer into the water, and then pour a little blue-black ink, stir evenly, put the clothes in, soak for half an hour, then take them out and wash them.

If it is hairy, wash it with juice from cooked spinach.

If the above methods cannot solve the problem of black pants turning red, you can try to go to a professional clothing maintenance point and dye the red areas of the black pants back to normal with dye.
