Process for preventing yellowing on textiles caused by reaction products of t-butylhydroxytoluene and t-butylhydroxyanisole

摘要

Yellowing on textiles, caused by reaction products of the oxidation stabilisers t-butylhydroxytoluene and t-butylhydroxyanisole and their derivatives in the presence of nitrates and nitrites, can be prevented if the yellow pigments formed are absorbed by means of suitable precautions on activated-charcoal fleeces. For this purpose, carrier fleeces are impregnated with a binder system and activated charcoal and the materials to be protected are shot into them or inserted as a separating layer.
