But in fact, its color fastness to washing and staining is better, which can no longer be explained by the theory of "easy to be washed off, so as not to stain the white ground"

Embodiment 1

[0097] 35.0 grams of the original dye shown in the formula (1-1), 2.4 grams of the original dye shown in the formula (1-2), 1.8 grams of the original dye shown in the formula (2-5), and the 10.8 grams of the original dye shown, 70 grams of dispersant MF, and 200 grams of pure water were used for micronization (dispersion treatment) with a sand mill, and then spray-dried to obtain a yellow-brown disperse dye composition. Based on the original dyes used, the mass fraction of component A represented by formula (1-1) and formula (1-2) is 74.8%, and the mass fraction of component B represented by formula (2-5) and formula (2-7) was 25.2%.

[0098] The dispersion stability of the disperse dye of the present invention at 71°C and 130°C was tested respectively according to GB / T 5540 and GB / T 5541-2007 by double-layer filter paper filtration method. Among them, the "residue" level at 71°C is level 4, and the "filtration time" level is level A; at 130°C, the "residue" level is still le...

Embodiment 2～20

[0106] According to the data shown in Table 1, Component A, Component B, Component C, Component D, Component E, Component F, 70 grams of dispersant MF and 200 grams of water were ground and dispersed with a sand mill chemical, and then spray-dried to make disperse dyes.

Embodiment 21

[0110] Get 0.25 gram of the disperse dye (owf=5%) that embodiment 1~20 makes and 0.075 gram of glacial acetic acid (1g / l), be made into 75 milliliters of dye liquors, put into 5.0 gram of polyester superfine fibers and spandex (12% ) blended fabric (commonly known as T+OP fabric, the gray fabric has been pre-set and scoured at 180-195°C) for dyeing, heated from room temperature to 130°C within 60 minutes, kept warm for 45 minutes, and took out the fabric when cooled to below 85°C. Treat the fabric with sodium dithionite and sodium hydroxide at 85°C for 20 minutes, then treat the fabric with an acidic reducing agent (such as hydroxyalkylsulfinate) at a pH of 3.5 to 5.0 at 85°C for 20 minutes, rinse with water, After drying, dry heat setting at 160°C for 30 seconds to obtain a deep colored fabric.

[0111] According to the 2A method stipulated in AATCC 61-2007 color fastness to home and commercial washing, GB / T5713-1997 textile color fastness test to water color fastness (equiva...

Abstract

The invention discloses a disperse dye composition, a dye product and an application thereof, belonging to the technical field of disperse dyes. The disperse dye composition is characterized in that the disperse dye composition contains one or more components A as shown in formula (1) and one or more components B as shown in formula (2); and the formulas (1) and (2) are as shown in the specification. The disperse dye composition disclosed by the invention can dye dark color on ordinary polyester fiber, polyester superfine fiber and polyester fiber and polyurethane blended material, and has good fastness to water washing and good compatibility.

Description

Technical field: [0001] The invention relates to a disperse dye composition, in particular to a disperse dye composition suitable for printing and dyeing hydrophobic fiber materials, especially suitable for printing and dyeing polyester fiber materials, containing a specific structure, dye products and applications thereof. Background technique: [0002] With the development of synthetic fiber blended materials and polyester superfine fiber textile materials, the performance requirements for disperse dyes are getting higher and higher. Especially when polyester superfine fiber and polyurethane fiber (spandex) blended materials are dyed, general disperse dyes can no longer meet the application requirements. The main reason is that general disperse dyes are easy to dye spandex and fall off easily, and severe thermal migration occurs when setting at high temperature, resulting in a decrease in color fastness. It is often difficult to achieve satisfactory washing fastness for p...
