DISPERSE DYES , special. non-ionic dyes for hydrophobic fibers, used in dyeing in the form of a finely dispersed aqueous suspensions. Do not contain groups imparting p-remote in the water, whereupon it is very low (at room t-re in 1 liter of water dissolves from a fraction to several. mg dye). Molecules disperse dyes are small (mol. M. 250-500).Disperse dyes are applied in the dyeing of polyester, polyamide and acetate fibers, at least - polyacrylonitrile (in bright colors), and when printing on fabrics mainly from a polyester and acetate fibers. Disperse dyes-unities. the group of dyes suitable for the dyeing of polyester and acetate fibers. Ensure receipt of colors full color gamut.In the process of dyeing molecules disperse dyes, converted to R-R, sorbed by the fiber and diffuse deep into him with formation of solid R-RA in the polymer. The dye is retained in the polymer mainly by van der Waals forces, in some cases - hydrogen bonds.Produce disperse dyes in the form of fine powders, granules or in liquid form (including toothpaste) with the size of the BSP. the mass of particles of not more than 1 to 2 microns; they include also secondary. in the society for the preservation of dispersion in the application and storage.
