VERFAHREN ZUM AUFHELLEN UND FAERBEN VON SYNTHESEFASERN

摘要

Process for the optical brightening and dyeing of textile material made of synthetic fibres by thermosoling in the presence of a thermosoling aid of the general formula I where r and s are from 0 to 8, although only either r or s can be > 0, f, g and h are each 0 or 1, f + g + h = 0 only when a = 0, m is from 1 to 100, a, b and c are each 0 or 1, d is 0 or 1, t is 0 or 1, but 0 only when at the same time r = 1, s = 0 and m = 1, R<1> is alkyl or alkenyl of 1 to 4 carbon atoms and preferably hydrogen, B is aliphatic or aromatic hydrocarbyl of from 1 to 22 carbon atoms optionally interrupted by bisfunctional groups (Q) and substituted by monofunctional radicals L and/or by halogen atoms, A is the same as B, M is C1-C10-alkylene or phenylene or xylylene, L is a monohydric functional group of the kind -OH, -OR<2>, -NR<1>R<1>, -NR<1>-CO-R<2>, -CO-NR<1>R<1>, -OCONR<1>R<1>, -NR<1>-CO-NR<1>R<1>, where R<2> can be the same as R<1> except hydrogen, Q is a bisfunctional hydrocarbon chain-interrupting group of the kind -O-, -S-, -SO2-, -NR<1>-, -CO-O-, -O-CO-, -O-CO-NR<1>-, NR<1>-CO-, -NR<1>-CO-O-, -NR<1>-CO-NR<1>- and Zn is hydrogen or an n-valent radical.N
