Black-dyeing process of basic dyeable polyester fibers

摘要

Basic dyeable polyester fibers are dyed with a mixture of dyes, the first of which is a quaternized-2-methylene indoline coupled to a substituted aminobenzene to form a hydrazide dye, the second of which is a quaternized amino triazol azo coupled to substituted diaminobenzene. The third dye is a quaternized alkoxybenzothiazol azo coupled to a substituted Di-Aminobenzene. The fourth dye is a substituted diaminotriphenyl methane dye and the last dye is a Nitrobenzeneazo- substituted aminobenzene.
