Abstract: A process for removing oligomer deposits from dyed and non-dyed textile materials which consist of polyester fibers or of blends of these fibers with other fibers, and from dyeing machinery, by a treatment with an aqueous, alkaline liquor which contains from 0.1 to 10 g/l of a quaternary ammonium compound carrying not less than two C6-C22-alkyl or -alkenyl groups on the quaternary nitrogen, at up to 100 DEG C. The oligomers are hydrolyzed and are removed together with the treatment liquor.
