The direct dye green.
Dyes - chemical compoundsthat have the ability intensively to absorb and convert the energy of electromagnetic radiation in the visible and near ultraviolet and infrared regions of the spectrum and used to give this ability to other bodies.
The least durable color on cellulose fibers give
direct dyes
. This is because they are attached to the fiber weak hydrogen bonds and ionic bonds. This type of connection already destroyed by the action of water or soap solutions at 30-40°C. To increase the color fastness to wet treatments fabric, dyed with direct dyes treated with solutions of special fixative - soluble polymers which, in joining fiber, prevent the separation from it of dye molecules. The magnitude of the affinity of the direct dyes to the fiber is related to the size and shape of their molecules. Molecules of direct dyes are coplanar and are very long. Except this is set to match the distance between sulforaphane in the dye molecule and hydroxy groups of the neighboring elements of the cellulose macromolecule. Dyeing with direct dyes produce more periodic way. To facilitate adherence of the dye to the cellulose fiber in the dye bath is administered 1-2% of soda ash (sodium carbonate) and 5-20% of salt (sodium chloride)by weight of the coated material.
