Application properties
Application fields
OPTAVON NW is used in pretreatment processes and dyeing.
Used for washing out of lubricants, alkaline scouring processes and hydrogen peroxide
bleachings, OPTAVON NW prevents precipitations of calcium and magnesium salts and shows
a high soil suspending power.
The above results have been obtained from trials in our laboratory and plant. In the light
of changing conditions they can only serve as a guide and are therefore offered without

OPTAVON NW
OPTAVON NW is fully effective in the strong alkaline range as well and can be used in
mercerising lyes and highly concentrated feeding liquors of continuous pretreatment systems.
In dyeings and subsequent washing operations, OPTAVON NW prevents the formation of
dyestuff agglomerates and supports the cleaning effect. OPTAVON NW has no negative
influence on the light fastness of a dyeing.
Guidelines for application
The calcium binding capacity of OPTAVON NW is about 190 mg CaCO3 /g product, and the iron
3+
binding capacity is 390 mg Fe /g product (both values at pH 11).
For water correction about
