FIELD: textiles, paper. ^ SUBSTANCE: invention is related to the field of dyeing-finishing production, namely to steam-phase dyeing of textile materials or natural suede. Proposed method of dyeing includes generation of unsaturated vapors of dye in process of dye evaporation in combination with thermoplastic polymer with their mass ratio of 1:3-1:5 at the temperature of 250-600C and pressure of 5-10-4 - 5-10-7 mm of mercury column and simultaneous dyeing in mixture of generated dye vapors and thermoplastic polymer. ^ EFFECT: method makes it possible to improve extent of dye fixation on material with preservation of material physical and mechanical properties due to elimination of undesirable structural changes of polymer material in process of steam-phase dyeing. ^ 1 cl, 2 tbl, 23 ex |
