FIELD: textile, paper.
SUBSTANCE: method of dyeing, which includes processing of pre-purified material by aqueous solution of an intensifying anion-active and emulsifying non-ionogen surfactant composition with its subsequent dyeing by cationic dye in an acid medium in the presence of an electrolyte at 125-130°C for 60 min, washing with hot water of at least 80°C, soaping and reduction treatment in a soda-hydrosulfite liquor. After drying at the stage of finishing the dyed material is subjected to impregnation with a composition consisting of a fluororganic drug, polacryl, polyvinyl alcohol, with subsequent drying and heat treatment.
EFFECT: method makes it possible to obtain a uniform intensive coloration with high strength properties.
