ABSTRACT:
Hydrophobic synthetic fabrics dyed in deep shades utilizing disperse dyes can be improved in solvent bleeding properties by subjecting the dyed fabric to treatment comprising exposure to an aqueous alkaline solution at elevated temperatures prior to the usual heat setting of the dyed fabric. The process is particularly useful for polyester fabrics derived from aromatic polyesters.
