[0033] Each get 0.5 gram of the blue disperse dye that embodiment 1-16 makes, be dispersed in the water of 500 milliliters, mix with 60 milliliters of water after imbibing 20 milliliters. Use acetic acid to adjust the pH of the dyeing bath to 5, raise the temperature to 70°C and put 2 grams of polyester / cotton cloth for dyeing, within 30 minutes, the temperature will rise from 70°C to 130°C (2 atmospheres), keep warm for 30 minutes, and cool to 90°C At that time, the dyed cloth samples were taken for testing. The national standards GB / T3921-1997, GB / T3920-1997, GB / T8427-1998, GB / T5718-1997 were used to test the color fastness to washing, rubbing, light and sublimation respectively. The test results are shown in Table 3.

Abstract

The invention discloses a blue disperse dye. The blue disperse dye mainly comprises the following components: 5-25 parts by weight of dye monomers A as shown in formula (I), 1-5 parts by weight of dye monomers B as shown in formula (II), 1-5 parts by weight of dye monomers C as shown in formula (III), 0.5-5 parts by weight of dye monomers D as shown in formula (IV), and auxiliaries can also be added in the blue disperse dye. The blue disperse dye disclosed by the invention is suitable for dyeing polyester materials, dyeing yarn and printing, and has the advantages of excellent high-temperature pad-dry-cure dyeing performance and excellent fastness performances, such as fastness to sunlight, fastness to sublimation and fastness to washing, and the certain performances are better than those of a commercially available finished product dye C. I. disperse blue 56.

Description

(1) Technical field [0001] The invention relates to a blue disperse dye, belonging to monoazo and anthraquinone dye compositions. (2) Background technology [0002] Judging from the current situation of textile fabrics, the proportion of fabrics made of a variety of 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 this type of textiles well: their thermal migration fastness and washing fastness are not ideal, which affects various wet fastnesses of textile dyeing, and also affects the surrounding environment. to more pollution. (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 blue disperse dye composition with high dye uptake, good washing fastness, excellent fastness, and low heat migration resistance, which ...
