Embodiment 1～7

[0020] According to the metering data shown in Table 1, dye monomer A, dye monomer B, auxiliary agent (dispersant methyl naphthalene sulfonate formaldehyde condensate (MF), diffusing agent benzyl naphthalene sulfonate formaldehyde condensate (CNF) , diffusing agent naphthalenesulfonic acid formaldehyde condensate (NNO), sodium ligninsulfonate) are mixed with water, grind and disperse with a grinder, and then spray dry.

[0021] Example

Embodiment 8～11

[0023] According to the measurement data shown in Table 2, disperse red dye C (commercial dye, monomer A content 35%), C.I. disperse orange 73 (commercial dye, monomer B content 35.4%), auxiliary agent (dispersant methyl naphthalenesulfonate Acid formaldehyde condensate (MF), diffusing agent benzyl naphthalenesulfonate formaldehyde condensate (CNF), diffusing agent naphthalenesulfonic acid formaldehyde condensate (NNO)) are blended with water, grind and disperse with a grinder, and then spray dry ;

[0024] Example

Embodiment 13

[0026] Take 0.5 grams of the disperse red dyes prepared in Examples 1-12 and disperse them in 500 milliliters of water, absorb 20 milliliters and mix them with 60 milliliters of water, adjust the pH of the dyeing bath to 5 with acetic acid, heat up to 70°C and put in 2 grams of The polyester / cotton cloth is dyed, the temperature is raised from 70°C to 130°C within 30 minutes, the temperature is kept for 30 minutes, and sampling starts when it is cooled to 90°C. 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 relates to a combiner of compound azo color, mainly be comprised of monomer of color A shown as (I) (10-35%) and monomer of color B shown as (II) (1-15%) and others as assistant . The compound dispersed red color is especially suitable for coloring polyester materials, yarn and dye printing, with outstanding coloring performance in high temperature and stability such as resistance to sunshine, sublimation and washing.

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 the existing disperse dyes, the purpose of the present invention is to provide a composite disperse red dye with excellent performance, which is suitable for dyeing multi-fiber combined fabrics such as polyester blended fabrics. [0004] Composite disperse red dye of the ...
