Color Fastness to Sea Water Test

The color fastness to sea water test is similar to the standard color fastness to water test, but uses seawater instead of distilled water. The test is used to evaluate the resistance of textile dyes to the specific conditions found in seawater, such as salt, minerals, and other impurities. The test procedure involves exposing a fabric sample to seawater, agitating it for a specified period of time, and then rinsing and evaluating the color change. The color change is rated on a scale, with higher numbers indicating better color fastness. This test is particularly important for textiles used in marine and coastal environments, such as boat covers, awnings, and outdoor furniture.
