Problems solved by technology

Among the yellow dyes, C.I. Disperse Yellow 42, C.I. Disperse Yellow 86, C.I. Disperse Yellow 163, and C.I. Solvent Yellow 163 are the most commonly used yellow high-solvent disperse dyes, but there are problems in each: C.I. Disperse Yellow 42 solar discoloration Heavy, poor lifting; C.I. Disperse Yellow 86 has light color and high cost; C.I. Solvent Yellow 163 also has the problem of light color and poor level dyeing when dyeing; while C.I. Disperse Yellow 163 is yellowish brown and cannot be used for brilliant Yellow and colorblocks using bright yellow

Embodiment 1-15 and comparative example 1-6

[0021] The dyes with the structure of Formula 1 and the dyes with the structures of Formula 2-1 to Formula 2-5 are mixed according to the ratio shown in Table 1, and 16 mg of the mixture is mixed with 49 mg of dispersant (using methylnaphthalenesulfonic acid formaldehyde condensate as the dispersant) After grinding and dispersing, add distilled water to make the volume to 100ml, add acetic acid / sodium acetate buffer solution to adjust the pH of the solution to 4.5, add 5g of polyester knitted fabric, heat up to 130°C and dye for 30 minutes, then take out the fabric sample for reduction cleaning, and fully rinse with water Dry to obtain yellow dyed fabric.

[0022] The light fastness test adopts the light fastness test method of Toyota Motor Corporation of Japan, using high-energy xenon lamps, and the irradiation density is 150W / m 2 (300-400nm), black panel temperature 73±3°C, 38 cycles of irradiation, each cycle including 3.8 hours of irradiation time and 1 hour of non-irradia...

Abstract

The present invention discloses a high-light fastness yellow disperse dye mixture and an application thereof, wherein the disperse dye mixture mainly comprises 75-25% by weight of a dye monomer A and 25-75% by weight of a dye monomer B, and the disperse dye mixture is provided for polyester fiber dyeing. According to the dye mixture, C.I.disperse yellow 163 (represented by a formula 1) is adopted as the one component of the dye mixture, and one or two dyes represented by a formula II are adopted as the other component, and the principle of blending synergy of the disperse dye is completely utilized, such that characteristics of excellent light fastness, excellent dyeing tolerance, excellent color change according to different light sources (used for blending gray, brown and other sensitive colors with no color change according to different light sources), and good application effect are provided when the obtained dye mixture is used for polyester fiber dyeing.

Description

【Technical field】 [0001] The invention relates to a yellow disperse dye mixture with high light fastness and application thereof, which is suitable for dyeing and printing polyester fibers and belongs to the technical field of fine chemicals. 【Background technique】 [0002] Polyester fibers are widely used in automotive interiors, home decorations, and tent fabrics. The dyed polyester fibers are required to have excellent light fastness, and the requirements for this light fastness are continuously improving. The light fastness requirements From the initial AATCC40AFU4 level, it has been improved to DIN75202 standard 1 / 10 depth and 1 / 1 depth level 3.5-4. At present, various brand automobile manufacturers have introduced their own light fastness standards, which are more stringent. [0003] There are fewer varieties of disperse dyes that can meet the above high light fastness requirements, especially in the case of light to ultra-light colors, even fewer can meet the light fa...
