Textile colour fastness

One of the most important quality criteria for coloured textiles is their ability to retain their colour and not to cause dyeing or colour change. Colour change usually means colour loss. Staining, the ability of colour to bleed from one material to another.

Colour assessment grey scale

One of the most common sources of consumer complaints is when coloured textiles change and vary greatly compared to the purchased product and are unacceptable to the user. A textile's ability to retain its colour can depend on many different things, including the choice of dye, dyeing technique and fixation. The colour’s ability not to degrade is also affected differently in different conditions, eg during wear (rubbing), washing, in contact with sweat, water and exposure to light. That is, a textile can have good colour fastness in one condition but poor in another. The colour fastness of the textile is therefore an important property to have control over. There are several evaluation methods. 

The colour shade between different batches in the textile production can also be of great importance. Colour measurement with absolute values ​​or delta E values ​​between different textiles are services we can perform.
