One problem that cannot be denied is the presence of optical brighteners in nearly all our modern detergents. Although these are beneficial to white linen since they prevent yellowing, they have a negative effect on coloured linen. The bright colours become pale when overlaid by the optical brighteners. This means that even new fabrics can soon look “washed out”.
What can we do to prevent this? The solution is to use only detergents without optical brighteners and chlorine bleach when you wash coloured linen. This avoids any changes in colour. The colours will remain as brilliant as on the first day.
For normally soiled washing, the temperature of the soapy water containing colour-care detergent should be 60 °C when you wash coloured fabrics made of pure linen or of a cotton/modal blend. However, you can increase this temperature to 95 °C when the washing is heavily soiled.
We recommend you to completely avoid using chlorine and detergents containing chlorine. In this way, you can make a significant contribution to protecting the environment and to extending the lifetime of fabrics.
