migrating property 在染色过程中，已上染到织物上的来固色的染料自然地通过染液转移到染料浓度较低的位置上去。对这种转移倾向的评价称为移染性。移染性好的染料，匀染效果好。它与延长染色时间没有直接的关系。
匀染剂具有缓染性和移染性，可有效改善染料的匀染性达到均匀染色的结果，从而提高染料的应用性能。
Levelling agent is one of important textile auxiliaries and it has dying performances such as migrating and retarding abilities. It can improve the dyeing result evidently.
选用春亚纺面料，在电解质元明粉存在的条件下，研究了耐盐高温匀染剂TF-212B对分散染料的高温分散性、移染性和消色性等染色性能的影响。
This article studied migration, dispersing and achromatic property of salt-resistance levelling agent TF-212B on polyester pongee under the existence of sodium sulphate.
