Process for treating natural polyamide fibres of asymmetric structure, such as wool, with liquid ammonia |
| 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.
