.beta.-N-aziridinopropionates of relatively high boiling alcohols or polyalcohols are prepared by transesterifying a .beta.-N-aziridinopropionate of a lower alcohol of 1 to 4 carbon atoms with a relatively high boiling alcohol or polyalcohol by a process in which the transesterification is carried out in the presence of, as a transesterification catalyst, a titanium(IV) or tin(IV) compound which is soluble in an organic medium.

Preparation of .beta.-N-aziridinopropionates

Process for the production of formaldehyde-free finishing agents for textiles containing or consisting of cellulose which is based on the reaction of urea or symmetrically disubstituted urea with glyoxal in the presence of buffer salts and alcohols at a pH of below 7, buffered mixtures of 4,5-hydroxyethyleneureas or N,N'-disubstituted 4,5-dihydroxyethyleneureas partially etherified in 4- and 5-positions being formed.

Process for the production of formaldehyde-free finishing agents for

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 C.sub.6 -C.sub.22 -alkyl or -alkenyl groups on the quaternary nitrogen, at up to 100.degree. C. The oligomers are hydrolyzed and are removed together with the treatment liquor.

Removal of oligomer deposits from textile materials

British Pat. No. 1,470,243 relates to aziridine compounds suitable for finishing wool, but the method of formulation, described there, of these compounds for practical purposes proved unsatisfactory. This problem is solved by the present invention.
