Washing colour fastness test, essential for life

The wash fastness test is a method of testing the colour fastness of textiles to washing. It helps textile manufacturers to determine the resistance of fibres to washing to ensure that the colours of the fibres are vibrant and do not become damaged or lose their colour through washing. It is an important indicator of the durability of a fabric's colour and can represent the vibrancy and washability of the fabric's colour.

 

Poor colour fastness is directly related to the health and safety of human beings. Products with poor colour fastness will cause the pigments on the fabric to fall off and fade when they are worn in the process of rain and sweat, and the molecules of the dyes and heavy metal ions may be absorbed by the human body through the skin and endanger the health of human skin. The colour fastness of washing can also affect other garments.
 

To summarise: The purpose of the wash fastness test is to test the colour fastness of fabrics when washed to ensure that they are not discoloured by washing during use.
