Tests for colour fastness to perspiration SS-EN ISO 105-E04

It is important that dyed textiles maintain their intended colour and do not bleed onto other fabrics and materials through staining. When we sweat, fabrics that come into contact with the skin can be affected, and if the colour does not adhere as it should, it can cause unwanted staining.

Syfte

One of the most common sources of consumer complaints is when dyed textiles change and vary too much from the purchased product and become unacceptable to the user. A piece of fabric can have good colour fastness in one state but worse in another. It can therefore be important to test a textile’s colour fastness when exposed to sweat. A good example is a light-coloured bra that is discoloured by a coloured shirt that has become moist from sweat. 

Poor colour fastness can be due to pretreatment, choice of dye, dyeing process, aftertreatment, and use.

Metod

The fabric is moistened with sweat liquid and placed under pressure at 37°C for 4 hours together with staining-fabric of the chosen fiber type. Colour change and staining are assessed in a light box under standardized light against a gray scale.
