FIELD: textile, paper. ^ SUBSTANCE: method includes washing raw material with active dye, steaming and flushing. It is proposed before the start of dyeing to determine constant of speed of active dye interaction with fibre Kcell, as well as dye resistance to steaming in the alkaline medium Y, which are used to determine the ratio H=Kcell/Y and depending on the produced value of H to correct process of dyeing by addition of alkaline agents in required concentrations - hydrocarbonate, carbonate or hydroxide of sodium and varying duration of material treatment with saturated steam. ^ EFFECT: method makes it possible to increase intensity of dyeing, to reduce dye consumption, to reduce in general the cost of technological process of cellulose-containing textile material dyeing, to expand areas of the method application by provision of the possibility to use bifunctional dyes, partially hydrolysed dichlorotriazine dyes and low reactive dyes, which were not used earlier in dyeing by pad-steam dyeing method. ^ 11 ex |
