Embodiment 1

[0049] Mix 21 grams of formula (1-1) dye component, 5.6 grams of formula (2) dye component, 0.4 grams of formula (3) dye component, 40 grams of dispersant MF and 33 grams of lignin 85A, add 200 grams of water and stir thoroughly Evenly, grind, disperse, and dry to obtain finished dyes, and dye yellow polyester with excellent fastness properties.

Embodiment 2

[0066] Add 50 grams of formula (1-1) dye component, 10 grams of formula (2) dye component, 20 grams of formula (3) dye component, 47 grams of dispersant MF and 33 grams of lignin 83A, add 300 grams of water and stir well Evenly, grind, disperse, and dry to obtain finished dyes, and dye yellow polyester with excellent fastness properties.

Embodiment 3-22

[0079] According to the formula in Table 3, a finished dye product was made according to the method of Example 2.

[0080] Table 3 Unit: Gram

[0081]

[0082]

[0083]

[0084] The finished dye products of Examples 3-22 were tested for performance.

[0085] The specific test method is as follows:

[0086] According to the similar method of GB / T2394-2003, respectively weigh 0.25 g of the dye products of Examples 3-22 into 250 ml of water to prepare a disperse dye suspension. Mix 40ml of disperse dye suspension with 60ml of water, adjust the pH of the dye bath to 5 with acetic acid, and then heat to 60°C. At the same time, put 2g of polyester fiber for high temperature and high pressure dyeing, and heat up to 130°C in 35 minutes. For 45 minutes, cool to 80°C for sampling.

[0087] Observe the shade of the cloth samples and use GB / T3921-2008, GB / T3920-2008, GB / T8427-2008, GB / T18886-2002, and refer to the compatibility determination method in Example 1, to determine their washing fastnes...

Abstract

The invention discloses a yellow disperse dye with excellent washing fastness, rubbing fastness, light fastness and saliva resistant fastness, and a preparation method and use thereof. The dye is wide in pH applicable range, good in compound compatibility of C.I. disperse red 60 and C.I. disperse blue 56, and especially suitable for dyeing of polyester / cotton blended fabrics.

Description

Technical field [0001] The invention relates to a yellow disperse dye, which is suitable for dyeing fabrics, especially polyester and its blended fabrics. Background technique [0002] With the increasingly serious environmental problems, many countries have issued a series of laws, regulations and policies to address environmental problems. In view of the most basic environmental protection requirements of the dye industry, banning azo dyes such as Disperse Yellow 23# will withdraw from the stage of history. However, this product has been used for more than a century and has been well-known and used to it. Finding a substitute for this product has become a top priority for dye producers. Although there are many substitutes on the market, they are all different from Disperse Yellow 23#. They either have a high cost, a narrow pH range, or poor compatibility with C.I. Disperse Red 60 and C.I. Disperse Blue 56, a large difference between the head and tail of the compound product, ...
