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° C.
Claims2
A low temperature, low bath ratio, tensionless and short-term continuous fabric dyeing apparatus using microwaves, comprising:
- a vessel containing a dye solution;
- guide rollers and an immersing roller for continuously feeding fabric into said vessel;
- squeezing rollers for squeezing and padding said fabric in said vessel;
- a drying station for continuously drying the dyed fabric in a tensionless state, said drying station including rollers mounted in a kettle for continuously passing the dyed fabric through the drying station;
- and
- a microwave generator for irradiating the dyed fabric in said kettle and heating said dyed fabric to a temperature of 100-130° C.
