Colorfast your new clothing, towels, rugs so the colors and dyes won't run. You will never again ruin clothing by dyes running. This will help you do laundry right. No more pink underwear and gray socks?
Colorfastness definition is that the ability to keep original dye color under the influence of other kinds of external factors in the use processes of dyeing textiles. Or we can define color fastness like this: Color fastness refers to the resistance of color to fade or bleed of a dyed or printed textile materials to various types of influences e.g. water, light, rubbing, washing, perspiration etc. It is an important indicator to measure the quality of dyeing products.
Clothing manufacturers should tell you if the garment is going to bleed. After all, they are the ones that know how the fabric was dyed. Most don't tell you outright because who wants to buy something that bleeds? But there are hints.
If the label says "wash separately" or "wash with like colors," that usually means that the dye isn't stable and is going to bleed or even rub off. Blue jeans can turn a light colored couch cushion blue because the dye rubs off.
It's even more important to heed the warnings when you have a stain to remove. The chemicals in stain removers are more potent than the detergents used in washing that are diluted in the washer. Obviously, bleaches such as chlorine bleach and hydrogen peroxide will remove color. But, other chemicals will remove color as well. That's why you have to test for colorfastness.
