VERFAHREN ZUR DAUERHAFTEN VERBESSERUNG DER TEXTILEN EIGENSCHAFTEN VON NATURLICHEN POLYAMIDFASERN, INSBESONDERE VON WOLLE

摘要

This invention relates to a process for treating natural polyamidic fibres of asymmetric structure, particularly wool, with liquid ammonia, in which a nucleophilic substance is added to said liquid ammonia. The treatment time is thus reduced and the dye affinity is improved.
