ANHYDROUS DYEING SYSTEM FOR YARN

The present disclosure relates to an anhydrous dyeing system for dyeing yarn by using vacuum transfer. The anhydrous dyeing system for yarn, according to the present disclosure, includes: a transfer printer which repeatedly sprays dye ink on a surface of a transfer sheet a plurality of times to laminate and apply ink layers; a dyeing jig which is in a drum form having a plurality of microholes formed in an outer circumferential surface thereof to penetrate inside and outside, wherein the yarn to be dyed and the transfer sheet on which the ink layers are applied are sequentially wound on the outer circumferential surface thereof; a process chamber into which the dyeing jig is put; a heating member for heating the yarn wound on the dyeing jig, by supplying heat to the inside of the process chamber; and a vacuum-generating member which is in communication with an internal space of the dyeing jig and vacuum-evacuates the air in the internal space of the dyeing jig to thereby form a vacuum pressure inside the dyeing jig.
