活性染料染色特性十大参数分析（二）

An Analysis on the Ten Major Dyeing Characteristic Parameters of Reactive Dyes ( Ⅱ )

活性染料染色特征的十大参数即:S、E、R、F值,移染指数MI值,匀染因子LDF值,易洗涤因子WF值,提升力指数BDI值,无机性值/有机性值和溶解度.十大参数对于活性染料的主要性能如:上染率、直接性、反应性、固色率、匀染性、重现性、拼混染料相容性和染色牢度等有重大的指导性和实用性.充分掌握了十大参数的含义和方法,对于染料生产者可以开发有用的染料和提供技术服务;对于染料应用者可以选好用好染料,提高印染织物质量.

The ten major dyeing characteristic parametess are S.E.R and Fvalues, migration index：Mi value, level dyeing Factor：IDF value, Freely washable factor： WF value, Build up factor： BDI value, inorganic/organic character and solubility. These ten major factors give importat guideines and practicality to the major properties of reactive dyes, such as：degree of dyeing, directness, reactiveness, degree of fixation, leveling property, repetitiousness, intermiscibility of mixed dyes and color fastness. Fully having a good command of the concepts and woys of using of these parameters will help dyestuff producers in their developing useful dyes and providing technical services; and so will do for dyestuff users in their selecting of proper dyes for improving their dyed fabrics＇properties.
