Abstract

The invention relates to a yellow dye composition, a yellow dye, and a preparation method and an application of the yellow dye. The yellow dye composition comprises: a component A represented by formula (I), wherein in the formula (I), X1 represents -H, halogen, -OCH3,-OSO2-Ph, -OSO2-CH3 or -CO-Ph, X2 represents -H or-NO2, R1 represents a C1-C4 alkyl group, and X1 and X2 cannot be H at the same time; and a component B represented by formula (II). The yellow dye composition and the yellow dye have excellent lifting power and excellent color fastness. The yellow dye composition and the yellow dye have good lifting property, and the dye has the advantages of good deep color lifting force, good leveling property, good compatibility and high suction rate, and is an economic and environmentally-friendly composite disperse dye with an excellent dyeing property.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a yellow dye composition, a yellow dye and a preparation method and application thereof. Background technique [0002] Acetate fabric has the characteristics of good hand feeling, gorgeous fabric and good air permeability, and has become one of the most popular fabrics on the market. Due to the structural characteristics of acetate fabric itself, disperse dyes with low molecular weight and good dispersibility are more suitable for the printing and dyeing of acetate fabrics. Single-component disperse dyes such as: C.I. Disperse Yellow 3 and C.I. Disperse Yellow 211, dyeing improvement and level dyeing Poor performance and low color fastness cannot meet market demand. [0003] Citation 1 discloses a yellow disperse dye composition and a dye product, and specifically discloses that the yellow disperse dye composition is composed of component A and component B, and the component A is selected fr...
