The dyeing method of polypropylene fibers applied reduction and oxidation of a cationic dye was investigated by using several dyes having phenyl phenazium, acridinium or oxazinium skeleton. Especially for dyes with phenoxazinium skeleton, Basic Blue 3 derivatives having different amino groups (dimethyl amino, diethyl amino, dipropyl amino, and dibutyl amino), counter anions (chloride, bromide, iodide, hydrogensulfite, and nitrate), and chalcogen elements (S and Se) were synthesized, and the effect of differences in their molecular structures on the dyeability was investigated. As a result, the effectiveness of dyes having the above skeleton for this dyeing method was confirmed. Moreover, the results showed that elimination and decomposition of substituents, hydrophobicity and bulkiness of the dye also affect the dyeability. © 2021 The Society of Fiber Science and Technology, Japan
