Problems solved by technology

Among them, Vat Blue 4 (I) is the earliest anthraquinone vat dye, which was first produced by German chemist R. Born in 1901. It is mainly used for cotton fiber dyeing and cotton printing, and is also used for cotton , Two-bath overdyeing of polyester-cotton fabrics, also used in the manufacture of pigments for inks, widely used, it has the advantages of bright color, light fastness, alkali resistance, wash resistance, perspiration resistance, etc., but poor chlorine bleaching resistance, when used alone, The coloring rate is not only low but also the color fastness is poor, which greatly affects the quality of use

Abstract

The invention provides a vat blue dye mixture with high chlorine-bleaching-resistant color fastness. The vat blue dye mixture comprises, in weight percent, 25-80% of dyes and the balance additives, the dyes comprise sulfonated vat blue 4, vat blue 6 and vat blue 66, and the additives comprise dispersing agents, color fixing agents and dedusting agents. According to the vat blue dye mixture, dyes are reasonably compounded, comprehensive color fastness of vat blue dyes is effectively improved, particularly, the chlorine-bleaching-resistant color fastness of the vat blue dyes is effectively improved, and the dyeing and printing quality of the vat blue dyes is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of dye compounding, in particular to a vat blue dye mixture with high chlorine bleaching fastness. Background technique [0002] Vat dyes (referred to as vat dyes) have a long history. Today, it and reactive dyes are important cotton dyes used to manufacture cellulose fiber advanced products or functional products. Especially with the rapid development of the national economy, people Consumer demand tends to be diversified, and the requirements for various properties of vat blue dyes are constantly increasing. Among them, Vat Blue 4 (I) is the earliest anthraquinone vat dye, which was first produced by German chemist R. Born in 1901. It is mainly used for cotton fiber dyeing and cotton printing, and is also used for cotton , Two-bath overdyeing of polyester-cotton fabrics, also used in the manufacture of pigments for inks, widely used, it has the advantages of bright color, light fastness, alkali resistance...
