Dye Fixing Agents
We provide Dye Fixing Agents (DFA) in cationic and non formaldehyde types. These are excellent in nature and are used for direct and reactive dyestuffs on the cellulose fiber. Another purpose of these products is to improve the rubbing fastness (washing and light fastness) for direct and reactive dyestuffs. These are generally slight yellow in color and are available in fluid form. Their ionic character is cationic and the chemical composition comprises nitrogen containing condensation product. The Dye Fixing Agents (DFA) are reactive in slightly acidic solution and are known to have following features:
1) Can be diluted with water to achieve specific concentration.
2) Non reactive and sustains high performance in presence of sulphate ions.
3) Resistant to salts present in hard water, acids and chlorides.
4) Can be stored for a long time.
