The invention relates to the field of textile printing and dyeing, and particularly discloses a blue dye composition and application thereof. The blue dye composition comprises a compound represented by a formula (I), at least one compound represented by a general formula (II), at least one compound represented by a general formula (III) and at least one compound represented by a general formula (IV). The blue dye composition disclosed by the invention can be widely applied to blended fabric coloring, the blended fabric can be dyed by using a one-bath method, the dyeing process is simplified, the dyeing efficiency is improved, and the blue dye composition has relatively good dyeing performance and relatively high color fastness.
Description
technical field [0001] This application relates to the field of textile printing and dyeing, more specifically, it relates to a blue dye composition and its application. Background technique [0002] Blended and interwoven fabrics have the excellent properties of the two fibers and are currently popular clothing fabrics. 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, and is not easy to wrinkle, easy to wash, and fast. Dry features. [0003] The dyeing of polyester-cotton blended fabrics, in order to ensure the dyeing quality, has been used for a long period of time by the dyeing process of the two-work method, that is, the polyester fibers are dyed with disperse dyes at a high temperature of about 130 ° C, and after reduction cleaning, Then dye cotton fibers with reactive dyes at room temperat...
