Problems solved by technology

[0008] The characteristic is that the yellow light is strong and bright, and the color light of its composition is more vivid. The synthesis process of this product is a proprietary technology mastered by the inventors of this technology, so there is no use of this dye as a component of the disperse golden yellow E-3RL composition. report

Embodiment 31

[0037] Weigh respectively 0.500g of the finished dyes prepared in Examples 1-30, add 100mL of water to the beaker, stir on a magnetic stirrer for 10 minutes, and after all disperse into a uniform suspension, move to a 500mL volumetric flask, and use distilled water Dilute to volume and shake well. Draw 20.0mL of the prepared dye solution, add 80.0mL of water, adjust the pH to 4.0-5.0 with 1% HAc-NaCl solution, add 2.0g of polyester fabric, make a sample in a dyeing proofer, and raise it to 130°C in 45 minutes. And keep at 130 DEG C for 45 minutes, cool to room temperature, take out the fabric, and fully wash with water to obtain bright yellow or golden yellow fabric.

[0038]Taking the dispersed golden yellow E-3RL100% sample as a standard, the color light and intensity are compared, and the intensity of the monoazo type composition dye of the present invention increases with the decrease of the amount of diffusing agent, up to more than 300%, and the color light is between ye...

Abstract

The invention relates to a disperse yellow dye, in particular to a monoazo type composition dye which is suitable for dyeing and printing polyester fabrics and blended fabrics thereof. The dye comprises a component I which is 2-chloro-4-nitrophenylazo-N'-ethyl-3'-cyano -4'-methyl-6'-hydroxy-2'-pyridone and a component II, wherein the component II can be a component II-1 which is 4-nitrophenylazo-N'-ethyl-N'-cyanoethylaniline or a component II-2 which is 4-nitrophenylazo-N'-cyanoethyl-N'-ethyoxyl formylaniline; the ratio of the component I and the component II in percentages by weight is preferably 60-95% : 40-5% and 30-95% : 70-5%, thus a wider yellow spectrum space can be provided. In addition, the invention also contains a diffusant which is preferably MF or sodium lignin sulfonate. Theinvention has the advantages of high migration ability, high intensity, and the like and can better substitute for disperse golden yellow E-3RL (disperse yellow 23) which is forbidden at present.

Description

technical field [0001] The invention relates to a disperse yellow dye, in particular to a disperse yellow dye suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Since the 1970s, the world's synthetic fiber production has accounted for 20% of all fiber production, and it has accounted for 50% since its development. The demand for disperse dyes in the printing and dyeing of ester fiber fabrics has greatly increased, especially the development of ultrafine fibers, which has doubled the demand for disperse dyes. [0003] As one of the three primary colors of low-temperature disperse dyes, Disperse Golden E-3RL (C.I. Disperse Yellow 23) is widely used in the dye industry because of its bright color, excellent color fastness, good level dyeing property, simple main raw materials and synthesis process, and low cost. It has always played a pivotal role, and the annual consumption increases with the increase in the output of polyester f...
