Cellulosic fiber are anionic and thus repulse anionic reactive dye molecules. In a conventional dyeing process this is overcome through the addition of salt to exhaust the dyestuff on the fabric.
Livinguard SFD forms a strong covalent bond with the cellulosic fiber and provides cationic groups to attract anionic dye molecules.
As reactive dye and alkali are added to the dyebath, the dye reacts with the cellulosic fiber forming covalent bonds. Dye molecules which reacted with water (hydrolyzed dye molecules) are strongly adsorbed by the cationic charges of Livinguard SFD.
Neutralization removes excess alkali but no dye molecules (colorless drain). No further washing is required as all dye molecules are strongly bound to the fiber.

ISO 105-X 12:2016
Method for determining the resistance of the color of textiles to rubbing off and staining other materials.
Two tests may be made, one with a dry rubbing cloth and one with a wet rubbing cloth.
Livinguard SFD with same dry rubbing fastness performance as conventional process across all 4 colors tested
Livinguard SFD with same wet rubbing fastness performance for red & navy, slightly lower performance for yellow & turquoise (still above standards for most brands at 3-4)
SO 105 C06:2010
Methods for determining the color resistance of textiles in all forms to domestic or commercial laundering procedures used for normal household articles using a reference detergent.
Livinguard SFD with overall comparable washing fastness performance across all 4 colors tested
Livinguard SFD meets or exceed standards for most brands
