Problems solved by technology

[0002] The traditional reactive brown SCE dye is composed of reactive navy blue, reactive yellow and reactive red SHE dyes. The advantage is that it is more economical, and the dyeing depth and wet fastness are better. The disadvantage is that the heat-sensitive discoloration is more obvious. A It will turn red under the light source, and the light color is poor in light fastness. Due to the inconsistent reactivity of the three primary colors of red, yellow and blue during cold pile dyeing, it is difficult to control the shade and cannot meet the requirements of high-demand textiles.

preparation example 1

[0018] Preparation Example 1: Synthesis of Reactive Brilliant Yellow

[0019] 1.0 mole of para-ester is diazotized with 1.05 mole of hydrochloric acid (using the remaining acid in the dry powder para-ester) and 1.0 mole of sodium nitrite according to the usual method to obtain a diazonium salt, and 1.0 mole of 10% 2 , in 4-diaminobenzenesulfonate sodium solution, carry out coupling reaction under the conditions of pH 4.5 and temperature 8-15 for 4 hours, and obtain a dye solution of C.I reactive yellow 201 sodium salt structure.

[0020] Beat 1.02 moles of cyanuric chloride with ice and water for 1 hour, add the above dye solution, react for 4 hours at pH 6.0~7.5, temperature 0~10°C, then add 1.1 moles of m-aminobenzenesulfonic acid , reacted at PH6.0~7.0, temperature 40-50℃ for 6 hours to obtain reactive brilliant yellow dye solution, which was purified by membrane treatment (further recrystallization purification, m / z: 829.93).

Embodiment 1

[0022] Divide and dry the mother liquors of the six dyes mentioned above including Brilliant Yellow, C.I Reactive Orange 107, Reactive Dark Blue M-R, Reactive Sea Blue (C.I Reactive Blue 203), Reactive Crimson, and Reactive Red SHE according to 50:10:10:10:12:8 , compounded, and added 10% of the total dye amount of sodium sulfate and 3% of dustproof agent for spray drying, commercialized to obtain commercial dyes.

[0023] Its Rf value is 0.89, moderate reactivity, 20°C solubility greater than 200g / l, 1 / 1 dyeing depth: light fastness level 5, soaping fastness level 4-5, perspiration fastness level 4-5, resistance to chlorine water immersion Fastness to grade 4, dry rubbing fastness to grade 4~5, wet rubbing fastness to grade 4, ironing fastness to grade 4, the performance of the product is better than other compounded reactive brown dyes, especially the reddish metamerism of A lamp And thermal discoloration phenomenon has been significantly improved.

Embodiment 2

[0025] Divide and dry the mother liquors of the above six dyes, including Brilliant Yellow, C.I Reactive Orange 107, Reactive Dark Blue M-R, Reactive Sea Blue (C.I Reactive Blue 203), Reactive Crimson, and Reactive Red SHE, according to 46:12:12:12:12:8 , compounded, and added 10% of the total dye amount of sodium sulfate, 5% of alkali-resistant diffusing agent JS-K and 3% of dustproof agent for spray drying, and commercialized to obtain commercial dyes.

[0026] Its Rf value is 0.89, moderate reactivity, 20°C solubility greater than 200g / l, 1 / 1 dyeing depth: light fastness level 5, soaping fastness level 4-5, perspiration fastness level 4-5, chlorine water immersion resistance Fastness to grade 4, dry rubbing fastness to grade 4~5, wet rubbing fastness to grade 4, ironing fastness to grade 4, the performance of the product is better than other compounded reactive brown dyes, especially the reddish metamerism of A lamp And thermal discoloration phenomenon has been significantl...

Abstract

The invention relates to a reactive golden yellow dye and a composite reactive brown dye. The reactive golden yellow dye is shown in a formula (I), while the composite reactive brown dye is prepared be compounding the reactive golden yellow dye shown in formula (I), C.I reactive orange 107, reactive dark blue M-R, C.I reactive blue 203, reactive dark red and reactive red SHE according to the mass ratio of (30-55): (5-12): (5-15): (5-15): (5-15): (5-15). The dyes can be used for dip dyeing, continuous pad dyeing, cold batching and shortened wet steaming processes, are low in directness, moderate in reactivity and high in product solubility, and have 1 / 1 dyeing depth, grade 5 of fastness to light, grade 4-5 of fastness to soaping, grade 4-5 of fastness to perspiration, grade 4 of fastness to chlorine water, grade 4-5 of fastness to dry rubbing, grade 4 of fastness to wet rubbing and grade 4 of fastness to ironing, and particularly, the phenomena of metamerism of redness and thermosensitive discoloration of a lamp A are improved obviously.
