Problems solved by technology

However, these dye compositions have poor dry heat sublimation fastness, poor compatibility, poor compatibility and color synchronization between the components of the composition, and a low success rate for one-time dyeing, especially when dyeing sensitive colors. Very unstable during production
The patent with the application number 201210237171.7 discloses an improved scheme with benzylpyridone dyes as the key component, but the dyeing depth and light fastness of this scheme are still lacking

Embodiment 1

[0075] 35.0 grams of the original dye shown in the formula (I-1), 2.4 grams of the original dye shown in the formula (I-2), 1.8 grams of the original dye shown in the formula (II-5), and the 10.8 grams of the original dye shown, 70 grams of dispersant MF, and 200 grams of pure water are micronized with a sand mill (for dispersion treatment), 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 (I-1) and formula (I-2) is 74.8%, and the mass fraction of component B represented by formula (II-5) and formula (II-7) was 25.2%.

[0076] The dispersion stability of the disperse dye of the present invention at 71°C and 130°C was tested respectively according to GB / T5540 and GB / T5541-2007 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 level 4, a...

Embodiment 11

[0087] Get 0.25 gram of the disperse dye (owf=5%) that embodiment 1~10 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.

[0088] According to the 2A method specified in AATCC61-2007 color fastness to home and commercial washing, GB / T5713-1997 textile color fastness test to water color fastness (equivale...

Abstract

The invention discloses a disperse dye composition which comprises the following components in percentage by mass: 1-99% of component A and 1-99% of component B; the structural formula (I) of the component A is shown in the description; and the structural formula (II) of the component B is shown in the description. According to the technical scheme disclosed by the invention, the disperse dye composition can obtain deep color on common polyester fiber, polyester ultrafine fiber, polyester fiber and polyurethane blend fiber materials; and the disperse dye composition has the advantages of excellent color fastness to washing, favorable thermal migration resistance, favorable fastness to dry heat sublimation, favorable high-temperature dispersion stability, and favorable coloring synchronicity and compatibility for dyeing.

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, its products and applications. 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 polyester-s...
