Abstract

The invention relates to the field of textile dyes, and particularly discloses a black dye composition as well as application and a dyeing method thereof. The black dye composition comprises one or more compounds represented by a general formula (I), one or more compounds represented by a general formula (II), one or more compounds represented by a general formula (III), one or more compounds represented by a general formula (IV) and one or more compounds represented by a general formula (V). General formula (I); general formula (II); general formula (III); general formula (IV); general formula (V); the black dye composition is applied to polyester-cotton blended fabric dyeing. The black dye composition disclosed by the invention has good dyeing performance and various color fastness, and can be used for simultaneously dyeing polyester and cotton under a one-bath process, so that the dyeing process is simplified, and the dyeing efficiency is improved.

Description

technical field [0001] The application relates to the field of textile dyes, more specifically, it relates to a black dye composition and its application and dyeing method. Background technique [0002] Blended and interwoven fabrics are currently popular clothing fabrics, which have the excellent properties of the two fibers. For example, polyester-cotton fabric not only highlights the style of polyester, but also has the advantages of cotton fabric. It has good elasticity and wear resistance under dry and wet conditions, stable size, small shrinkage, tall and straight, not easy to wrinkle, and easy to wash. , Quick-drying characteristics. [0003] In actual production, when dyeing polyester-cotton blended fabrics, in order to ensure the dyeing quality, the so-called two-job dyeing process has been used for a long time, that is, polyester fibers are dyed with disperse dyes at high temperature (about 130°C), and after reduction cleaning, Then at normal temperature (below 1...
