浅谈毛用活性染料的染色

Discussing briefly about dyeing of reactive dye for wool

文章介绍了常用毛用活性染料的类型及其使用情况。在此基础上重点介绍了乙烯砜活性基活性染料使用过程中染色温度对固色率、重现性的影响和实现低温染色的意义和方法。由于乙烯砜活性基活性染料固色率较低,文章认为用碳酸钠配合合适的洗剂做后处理能有效提高产品色牢度。文章还指出煮呢毛沾色牢度较差是乙烯砜活性基类染料的缺点,做精纺深浅色交织毛织物需特别小心。

The text introduces the classification and application of reactive dye most in use for wool, on this basis, it also focuses on vinyl sulfone reactive dyes in the process of dyeing temperature influence on fixation yield and reproducibility, and points out low temperature dyeing is very important and how to achieve it. Due to fixation yield of vinyl sulfone is low, use sodium carbonate combine with suitable detergent can effectively improve product color fastness in post-treatment. Poor staining on wool of crabbing fastness is the disadvantage of vinyl sulfone reactive dyes, you must be careful when you process light and dark color worsted woolen union.
