ANHYDROUS FIBER DYEING MACHINE FOR MIXING FLUID MEDIUM

WIPO Patent Application WO/2020/077666

A1

Disclosed by the present invention is an anhydrous fiber dyeing machine for a mixing fluid medium, comprising a dyeing cylinder, a carbon dioxide pressurizing system and a polar medium pressurizing system, a cotton stepping system, a circulating dyeing system, a carbon dioxide recovery system, a polar medium separation and recycling system and an automatic unloading system. Since two sets of carbon dioxide media and polar media pressurizing, separation and recovery systems are provided in the anhydrous fiberdyeing machine, dyeing processing of the mixed fluid medium in an anhydrous fiber-dyeing vat, a dyeing circulation system of the vat, and effective modification of the hydrophobic carbon dioxide fluid medium are effectively achieved, so that the dyeing performance and dyeing effect of special dye molecules on hydrophilic natural fibers are remarkably improved. At the same time, by employing the cotton stepping system and the unloading system provided in the technology of the present invention, the treading efficiency of the dyeing vat is notably improved, and the yield of processed products and the automated operation are enhanced.
