The invention relates to the field of textile printing and dyeing, and particularly discloses a yellow dye composition and application thereof. The yellow dye composition comprises one or more compounds represented by a general formula (I), one or more compounds represented by a general formula (II) and one or more compounds represented by a general formula (III). General formula (I); general formula (II); and general formula (III). The composition can be used for blending and coloring cellulose fibers, polyamide fibers, protein fibers and fibers, can be dyed by a one-bath process, is convenient to use, and has very excellent dyeing performance and various color fastness.
Description
technical field [0001] This application relates to the field of textile printing and dyeing, more specifically, it relates to a yellow dye composition and its application. Background technique [0002] Blended fabric is a textile product that has the excellent properties of two or more fibers. For example, the polyester-cotton blended fabric has both the characteristics of polyester and the advantages of cotton fabric. It has good elasticity and abrasion resistance under dry and wet conditions, and its size is very stable, its shrinkage rate is small, and it is not easy to dry. Wrinkled, easy to wash, and quick-drying, it has become one of the most widely used blended fabrics in people's daily life. [0003] At present, in order to ensure the dyeing quality, the dyeing of polyester-cotton blended fabrics has long been dyed using the so-called two-job dyeing process, that is, polyester fibers are dyed with disperse dyes at a high temperature of about 130°C, and after reducti...
