Definitions

  • the invention relates to mixtures of mixed-alkylated methylolated 4,5-dihydroxy-imidazolidin-2-ones.
  • the invention also relates to a process for the preparation of said mixtures, finishing baths therefrom and their use.
  • Methylolated 4,5-dihydroxy-imidazolidin-2-ones are used in textile finishing as low-formaldehyde crosslinkers. They are also described as DMDHEU compounds [see Ullmann's Encyclopedia of Industrial Chemistry, Vol. A 26, pages 227 to 350]. These textile crosslinkers bring about a good crease recovery and reduce the textile shrinkage. DMDHEU derivatives reacted with methanol provide good easy-care effects. At the same time, the formaldehyde content of the textiles treated with such DMDHEU derivatives is low. However, the disadvantage of this is high emissions from the user, i.e. in textile finishing, through a residual methanol content or through partially split off methanol.
  • mixtures of mixed-alkylated methylolated 4,5-dihydroxy-imidazolidin-2-ones which can be prepared by reacting methylolated 4,5-dihydroxy-imidazolidin-2-ones (DMDHEU) with a monovalent C ⁇ Alcohol and a polyol selected from the group comprising ethylene glycol, diethylene glycol, 1,2- and 1,3-propylene glycol, 1,2-, 1,3- and 1,4-butylene glycol, glycerol and polyethylene glycols Formula HO (CH 2 CH 2 O) n H with 3 ⁇ n 20 20, the monohydric C 5 alcohol and the polyol being used in an amount of 0.1 to 2.0 molar equivalents, based on DMDHEU, and the Reaction takes place at temperatures of 20 ° C to 70 ° C and a pH of 1 to 2.5, and the pH is adjusted to a value of 4 to 8 after the reaction.
