Abstract

A low temperature, low bath ratio, tensionless and short-term dyeing method using microwaves, comprises the steps of: immersing dyed goods in a vessel filled with dye solution comprising water present in an amount twice as much as the goods to be dyed, a disperse dye present in a ratio of disperse dye to goods to be dyed of 1:1000, a dispersing agent present in a ratio of dispersing agent to dye of below 1:100, and irradiating the dyed goods with microwaves below 2450 MHZ in order to heat them to a temperature of 100-130.degree.
