overflow-wrap: break-word !important;">常用粉状轻质纯碱5～25g/L，pH=10.65～10.99，其pH缓冲能力很大。因此，根据所染色泽的深浅，纯碱用量5～20g/L已足矣。用量过多，得色深度提高不明显，反而会降低染料在盐碱固色浴中的溶解稳定性，危害染色质量。</span></section><section style="margin: 0px 8px;

overflow-wrap: break-word !important;"> 一是，纯碱的加入，必须建立在“吸色平衡且吸色均匀”的基础上。也就是说，只有在中性盐浴（吸色浴）中，真正达到吸色平衡而且经移染实现吸色均匀之后，碱剂方可加入。这是因为，达到吸色平衡后，残留染液浓度最低，而染液浓度越低，碱剂加入后染料的凝聚倾向越小，二次吸色速率越温和，产生染疵的概率越小。碱剂加入后，纤维上的染料会因发生固着而丧失移染能力。这会使吸色阶段产生的不均匀性变为永久性疵点。</span></section><section style="margin: 0px 8px;
