Problems solved by technology

[0004] Textiles (including fur clothing) treated with fluorescent dyes have a novel appearance and can well meet people's high requirements for specific colors; The rate is low, which leads to a large amount of colored dyes in the residual night; on the one hand, it does not meet the environmental protection requirements after discharge; on the other hand, it directly leads to the waste of raw materials

preparation example Construction

[0037] The fluorescent dye provided by the present invention contains an acid dye and auxiliary agents such as sodium polymethylnaphthalenesulfonate, sodium xylenesulfonate, diffusing agent, and pull-off powder in predetermined parts by weight. Among them, sodium polymethyl naphthalene sulfonate is used as an absorption aid, which can make the fur absorb the dye as much as possible, greatly improving the absorption rate of the fur to the dye; thus ensuring that the residual night after dyeing is in a colorless state . Sodium xylene sulfonate is a solubilizing conditioning additive, which is beneficial to the effective dissolution of each additive component. Diffusion agent MF has excellent diffusivity and thermal stability, and it can make dyes bright in color, high in color strength and even in coloring. Pull-off powder is added to the fluorescent dye as a penetrating agent and wetting agent, which can significantly reduce the surface tension of water, has excellent penetrat...

Embodiment 1

[0043] The fluorescent dye provided in the embodiment of the present invention, in parts by weight, includes: 1610 parts of acid green, 5 parts of sodium polymethylnaphthalene sulfonate, 5 parts of sodium xylene sulfonate, 1 part of diffusing agent MF, and 5 parts of pull-away powder .

[0044] Preparation

[0045] S11: Add 1610 parts of acid green into the mixing kettle;

[0046] S12: Make the temperature reach 10°C, add 5 parts of sodium polymethylnaphthalene sulfonate, 5 parts of sodium xylene sulfonate, 1 part of diffusing agent MF, 5 parts of pull-off powder and a certain amount of water;

Abstract

The invention provides a fluorescent dye, and relates to the field of fur dyeing. The fluorescent dye comprises the following raw material components: 10-90 parts of acid dye, 5-20 parts of polymethylnaphthalene sodium sulfonate, 5-50 parts of sodium xylene sulfonate, 1-10 parts of dispersing agent MF1-10 and 5-50 parts of nekal. The fluorescent dye provided by the invention has the greatest advantage that the absorbing rate is very high (residual liquid left after dyeing is colorless, the absorbing rate is approximate to 100 percent, the dye is saved greatly, and meanwhile the residual liquid reaches a discharge standard and meets the requirement on environmental protection). Moreover, fur dyed with the fluorescent dye has high light fastness and wet rubbing fastness.

Description

technical field [0001] The invention relates to the field of fur dyeing, in particular to a fluorescent dye and its preparation method and application. Background technique [0002] Dyes that can strongly absorb in the range of visible light and radiate fluorescence are called fluorescent dyes. Since the 20th century, organic fluorescent dyes have been widely used in various industries such as textiles, plastic dyeing, and printing pigments. [0003] Organic fluorescent dye is a kind of functional dye, which not only has the coloring characteristics of conventional dyes, but also can emit fluorescence; it can improve the saturation and vividness of fabrics. Nowadays, with the improvement of people's living standards, the requirements for textiles are gradually shifting from practical to colorful and enjoyable, and the requirements for novel colors of clothing fabrics are also getting higher and higher. [0004] Textiles (including fur garments) treated with fluorescent dyes...
