Method for continuous dyeing polyester pile fabrics: aromatic nitrile ether or oxyethylated chlorophenol fixing accelerator

A method of continuously dyeing textile fabrics formed at least partially of polyester fibers comprising

• (1) advancing the fabric through a continuous dyeing range and through a dyestuffs applicator and impregnating the fabric with an aqueous dyebath comprising
• (a) 0.5 to 5 g/l of a thickener
• (b) disperse dyestuffs in an amount sufficient to dye the fibers to the desired depth of shade
• (c) 2 to 100 g/l of a partially sulfated adduct of ethylene oxide with an alkyl phenol or C.sub.8 to C.sub.16 fatty alcohols
• (d) 2 to 60 g/l of nonionic or anionic surfactants, and
• (e) 5 to 50 g/l of at least one organic compound selected from the group consisting of aromatic nitrile ethers and ethoxylated chlorophenols;
• (2) continuously directing the fabric from the dyestuffs applicator to and through a heating chamber and heating the fabric to a temperature and for a time sufficient to fix the dyestuffs, and
• (3) washing and drying the thus dyed fabric.

• (e) 5 to 50 g/l of at least one organic compound selected from the group consisting of benzyloxypropionitrile, chlorobenzyloxypropionitrile, methylbenzyloxypropionitrile, diethylene glycol monochlorophenyl ether, and triethylene glycol monochlorophenyl ether;
• (2) transferring the fabric from the dyestuff applicator to a steamer and steaming the wet, impregnated fabric for 1 to 20 minutes at 96.degree.-105.degree. C. to fix the dyestuffs on the fabric;
• and
• (3) washing and drying the thus dyed pile fabric.
