PROCESS FOR TREATING NATURAL POLYAMIDIC FIBRES OF ASYMMETRIC STRUCTURE SUCH AS WOOL WITH LIQUID AMMONIA |
| 摘要 |
<p>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.</p> |
