Dyes and pigments are the most important colorants used to add a color or to change the color of something. They are widely used in the textile, pharmaceutical, food, cosmetics, plastics, paint, ink, photographic and paper industries. Dyes are colored substances which are soluble or go into solution during the application process and impart color by selective absorption of light.
Dye Fixing Agent (DFA) is a cationic dye-fixing agent, which improves the wet fastness of dyed or printed cotton cellulosic good on which direct reactive or after copper able dyes are used. DFA is stable in hard water. Dilute acids, and low electrolyte concentrations. It is precipitated in presence of strong alkalies and salts of mineral acids. Weakly acidic solution improves the stability of DFA towards salts. DFA is not compatible with anionic products but cationic softness can be used the same bath.
Dye fixing agent prevents the fabrics from color fading by washing, etc, by bonding chemically with unfixed excess dye on the fabrics. The imperative need of textiles in every aspect of life has been the premise for the growth of the global textile chemicals market. Coloring of fabrics, yarns and fibers is a crucial process in textile manufacturing. Textile dyes, therefore, represent an important chemical feedstock in textile production. As a whole it is a good project for new entrepreneurs to invest.
