How Do Manufacturers Test Colorfastness in Activewear?

Colorfastness testing evaluates how well activewear retains color and whether it stains other materials under defined conditions.

Washing, rubbing, perspiration, and other exposures require different methods selected for the intended use. A good result in one test does not establish resistance to every exposure.

Agree on the relevant methods and grading criteria with a textile laboratory, and test representative colors and production materials before making durability claims.
