摘要
通过对传统的酸性络合染料在结构上进行改性，使其可在相对安全的ｐＨ条件下（３．５～４）对羊毛染色．在上述条件下，与传统染料染色情况相比，染料对纤维的上染速率明显下降，同时染料在纤维上的扩散速率明显提高，从而为这一改性染料在上述ｐＨ条件下具有良好的匀染性能提供了可靠的保证．
Palatin Fast Dyes were chemically modified and the products can be applied in wool dyeing under the conditions of safe pH ranges (3.5～4.0).Under these conditions the exhaustion rates were significantly decreased and the dye migration in the fibre increased which provide the possibility of level dyeing when using these modified dyes.
