FIELD: textile, paper.
SUBSTANCE: dyeing device comprises cylindrical vessel with dyeing and air chamber. Heating element and dispersed dye are arranged in dyeing chamber. Thread passes through both chambers with the help of guide rolls and thread guide. Compressed air is supplied into air chamber to change pressure in dyeing chamber, in order to increase concentration of dye molecules adsorbed by thread.
EFFECT: simplified dyeing process, elimination of some technological operations in process of dyeing, reduced power inputs, reduced time of dyeing, more even dyeing and higher extent of dye fixation on fibre.
