Continuous dyeing of cationic dyeable polyester fibers

摘要

Textile fabrics formed at least partially of cationic dyeable polyester fibers are dyed in a continuous process with an aqueous dyebath comprising (a) 0 to 5 g/l of thickener; (b) cationic dyestuffs in an amount sufficient to dye the cationic dyeable polyester fibers to the desired depth of color; (c) 2 to 100 g/l of a partially sulfated adduct of ethylene oxide with an alkyl phenol or C8 to C16 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. The fabrics are continuously dyed by padding, immersing, spraying or otherwise applying the dyestuffs, steaming the fabrics in their wet condition, and subsequently washing and drying.
