Embodiment 1
[0049] Mix 21 grams of dye components of formula (1-1), 5.6 grams of dye components of formula (2), 0.4 grams of dye components of formula (3), 40 grams of dispersant MF and 33 grams of lignin 85A, add 200 grams of water and stir well Evenly, grind and disperse and dry to obtain the finished dye, and dye it to obtain 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 and disperse and dry to obtain the finished dye, and dye it to obtain yellow polyester with excellent fastness properties.
Embodiment 3-22
[0079] According to the formula in table 3, dye finished product is made according to the method for embodiment 2.
[0080] Table 3 Unit: Gram
[0081]
[0082]
[0083]
[0084] The dye finished products of embodiment 3-22 are carried out performance test.
[0085] The specific test method is as follows:
[0086] According to a method similar to GB / T2394-2003, weigh 0.25 grams of the dye products of Examples 3-22 into 250 ml of water to prepare a disperse dye suspension. Draw 40ml of disperse dye suspension and mix it with 60ml of water, adjust the pH of the dyeing bath to 5 with acetic acid, then raise the temperature to 60°C, and at the same time put 2g of polyester fiber into it for high temperature and high pressure dyeing, heat up to 130°C within 35 minutes, keep warm After 45 minutes, cool to 80°C and sample.
[0087] Observe the color light of the cloth sample and adopt GB / T3921-2008, GB / T3920-2008, GB / T8427-2008, GB / T18886-2002, and refer to the compatibil...

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] As environmental protection issues become increasingly severe, many countries have issued a series of laws, regulations and policies for environmental protection issues. 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. Yet this product has been used for more than a century, has been well known and used to by people, and it has become a top priority for dyestuff producers to find a substitute for this product. Although there are many substitutes on the market, they are all different from Disperse Yellow 23#. They either cost too much, or have a narrow pH range, or have poor compatibility with C.I. Disperse Red 60 and C.I. Disperse Blue 56, or have a large difference betwee...
