Test standard for light fastness of textiles

October 29, 2020

In the context of new requirements and standards for light fastness, textile companies must understand and master the test standards and technical requirements for light fastness

Related standards for light fastness test

Light fastness
Sunlight refers to exposure to sunlight under the specified conditions not exposed to rain, and then the blue wool standard is used to evaluate the light fastness.

Color fastness to artificial light
Xenon arc refers to exposure to an artificial light source equivalent to sunlight under specified conditions, and then the blue wool standard is used to evaluate the color fastness to light.

Color fastness to weather
Outdoor exposure refers to outdoor exposure under specified conditions without any protection, and then compare it against the blue wool standard to evaluate its color fastness.

Color fastness to artificial weather
Xenon arc refers to spray exposure in a xenon lamp tester under specified conditions, and then compare with the blue wool standard to evaluate the color fastness.

Main measuring range
1.Light fastness test of dyes: light fastness test of dyes under light (wavelength 380nm~750nm) and certain temperature and humidity conditions

2. Weather fastness test of dyes: The weather fastness of dyes is determined under the combined influence of light (wavelength 380nm~750nm), certain temperature, humidity and rain.

3. Weather fastness test of textiles, etc.: Test the weather fastness of textiles under the combined action of light (wavelength: visible light 380nm~750nm; ultraviolet light 300nm~380nm) and climatic conditions

The xenon lamp solar aging tester is specially designed for the solar test standards of dyes, textiles and automobile interiors.
