ABSTRACT:
Disclosed is a treatment process for textile substrates comprising or consisting of regenerated cellulose, which process comprises applying to the substrate an aqueous medium comprising (A) a monomeric, hydrolysis stable, hydrosoluble, resin forming cross linking agent containing at least two N-methylol or N-alkoxymethyl groups, (B) a hydrosoluble, prepolymerised, linear, filler resin forming, cross-linking agent, also containing at least two N-methylol or N-alkoxymethyl groups, (C) a reactive acetal of formula ##STR1## wherein X and Y, independently, are H or CH.sub.2 OH, (D) a first cross-linking catalyst, being an alkaline earth metal salt of a strong acid and (E) a second cross-linking catalyst, being an acidic aluminium salt, subsequently drying the substrate and subjecting same to a temperature at which cross-linking takes place, and an aqueous concentrate for use therein.
