Colour Fastness to Light

When Colour Matters!

Hi Vis garments need to maintain their colour in order to remain compliant.

When in use, textile fabrics are exposed to sunlight, this light tends to destroy colouring materials, that result in faded fabric. Dyes vary enormously in their reaction to light and an objective measure of colour fastness to light is required.

ISO 105-B02:2014 specifies a method intended for determining the effect on the colour of textiles of all kinds and in all forms to the action of an artificial light source representative of natural daylight (D65). The method is also applicable to white (bleached or optically brightened) textiles.

NZWTA are specialists in measuring colourfastness to light. We also provide colour fastness to washing and a range of other properties.
