The invention relates to the field of textile dyes, and particularly discloses a red dye composition as well as application and a dyeing method thereof. The red dye composition comprises one or more compounds represented by a general formula (I) and one or more compounds represented by a general formula (II). General formula (I); and general formula (II). The red dye composition has good dyeing performance and various color fastness, can be widely applied to coloring of cellulose fibers, polyurethane fibers, protein fibers and other fibers and various blended fabrics, can dye polyester cotton and other materials at the same time under the one-bath process, simplifies the dyeing process, and improves the dyeing efficiency.
Description
technical field [0001] The application relates to the field of textile dyes, more specifically, it relates to a red 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 100...
