NITRATE-FREE CATALYST FOR HIGH-GRADE-FINISH TEXTILES

摘要

Substantially nitrate-free catalysts for high-grade-finish textiles with formaldehyde-free wetting agents, containing magnesium, tetrafluoroborate, chloride and sulphate ions in the molar weight ratios of (a) Mg2+ : BF4- = 1 : 0.1 to 4, (b) Mg?2+ : Cl-¿ = 1 : 1.7 to 15, and (c) SO¿4??2- : Cl-¿ = 1 : 0.2 to 4.
