Example Embodiment

[0096] Example 1

[0097] 35.0 g of the original dye represented by formula (1-1), 2.4 g of original dye represented by formula (1-2), 1.8 g of original dye represented by formula (2-5), and formula (2-7) 10.8 g of the original dye shown, 70 g of the dispersant MF, and 200 g of pure water are used together with a sand mill for micronization (for dispersion treatment), and then spray-dried to obtain a yellow-brown disperse dye composition. Based on the original dye 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) Is 25.2%.

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

Example Embodiment

[0109] Example 21

[0110] Take 0.25 g of the disperse dyes prepared in Examples 1-20 (owf=5%) and 0.075 g of glacial acetic acid (1g / l) to make 75 ml of dye solution, and put in 5.0 g of polyester superfine fiber and spandex (12%). ) Blended fabric (commonly known as T+OP cloth, the grey fabric is pre-formed and refined at 180~195℃). The fabric is dyed from room temperature to 130℃ within 60 minutes, kept for 45 minutes, and cooled to below 85℃. Treat the fabric with sodium dithionite and sodium hydroxide at 85°C for 20 minutes, and then treat the fabric with an acid reducing agent (such as hydroxyalkyl sulfinate) at a pH of 3.5 to 5.0 at 85°C for 20 minutes, and rinse with water. Dry, dry heat and set at 160°C for 30 seconds to obtain a deeply colored fabric.

[0111] Respectively according to the 2A method specified in AATCC 61-2007 home and commercial washing color fastness, GB / T5713-1997 textile color fastness test water fastness (equivalent to ISO 105-E01), GB / T5718-1997 te...

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...
