Abstract
Essentially nitrate-free catalyst for the wash-and-wear finishing of textiles with formaldehyde-free crosslinkers, comprising magnesium, tetrafluoroborate, chloride and sulfate ions in the molar weight ratios of (a) Mg.sup.2+ : BF.sub.4.sup.- =1:0.1 to 1:4, (b) Mg.sup.2+ : Cl.sup.- =1:1.7 to 1:15 and (c) SO.sub.4.sup.2- : Cl.sup.- =1:0.2 to 1:4.
