PROCESS FOR CONTINUOUS DYEING OF A TEXTILE FILAMENT, AND INSTALLATION FOR IMPLEMENTING THE PROCESS
The aim of the invention is to perfect a process for continuous dyeing of a textile filament by impregnation under pressure, followed by pneumatic drying. The dye solution is applied to the filament (1) in an impregnation enclosure (4). The filament then passes into a pneumatic drying enclosure (5) in which the liquid is recovered for regeneration and reuse as a dye. A regeneration enclosure (14) is connected to an automatic colour analyser (34) and to a calculating unit (34') which controls the dye dosers (86).
