Description

(1) Technical field

[0001] The present invention relates to a monoazo dye composition. (2) Background technology

[0002] From the current situation of textile fabrics, the proportion of fabrics composed of various fibers is increasing year by year, such as some domestic high-end fabrics, including polyester blended fabrics. The disperse dyes currently available on the market cannot meet the printing and dyeing needs of such textiles well: their thermal migration fastness and water washing fastness are not ideal, which affects various wet fastnesses of textile dyeing, and also brings pollution of the surrounding environment. (3) Contents of the invention

[0003] In order to overcome the deficiencies of existing disperse dyes, the object of the present invention is to provide a disperse red dye composition with high dye uptake, good washing fastness, excellent fastness, and low heat migration resistance, which is suitable for multi-fiber composite fabrics such as Dyeing ...
