Problems solved by technology

[0005] In the traditional polyester fabric dyeing and finishing process, the pretreatment desizing, refining and alkali weight reduction processes are carried out under alkaline conditions, while the dyeing of disperse dyes is carried out in an acidic bath, resulting in the precipitation of unwashed pulp in the pretreatment and defects At present, most of the dyes available for alkaline dyeing in the market are blue-black and other dark colors, and it is necessary to further develop alkali-resistant dye varieties to create conditions for the one-bath method of refined dyeing of polyester fabrics

Embodiment 1

[0053] With 45 grams of formula (I-1) compound, 30 grams of formula (II-1) compound, 25 grams of formula (III-1) compound and 250 grams of dispersant MF, after adding 2500 grams of water, blending, grinding and dispersing and drying, The finished product is obtained. The dye can provide yellow-brown tone to polyester and its blended fabrics.

Abstract

The invention discloses a disperse yellow-to-orange dye composition and a product and application thereof. The disperse yellow-to-orange dye composition comprises a component A, a component B and a component C. The component A is selected from at least one of compounds shown in the following formula (I), the component B is selected from at least one of compounds shown in the following formula (II), and the component C is selected from at least one of compounds shown in the following formula (III). Based on the component A, the component B and the component C, the mass percentage of the component A is 5-90%, the mass percentage of the component B is 5-90%, and the mass percentage of the component C is 5-90%. The invention provides an application of a disperse yellow-to-orange dye composition and a product thereof in hydrophobic fiber material printing and dyeing. The disperse yellow-to-orange dye composition and the product thereof have the characteristics of bright colored light, excellent color fastness to washing and light fastness, acid and alkali bath dyeing resistance and the like.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse yellow to orange dye composition and its products, as well as its application in printing and dyeing of hydrophobic fiber materials. [0003] (2) Background technology [0004] There are many types of yellow or orange disperse dyes, commonly used such as disazo-type disperse yellow 23 and monoazo-type disperse orange 76, which are banned due to easy decomposition of carcinogenic and allergenic components; nitrodiphenylamine-type disperse yellow 42, good fastness, suitable for a variety of fibers, and the dyeing performance needs to be improved; quinoline-based Disperse Yellow 54 has a bright shade. With the prohibition of Disperse Yellow 23 in recent years, its usage is increasing. The above three disperse dyes can be colored under weak alkaline conditions, but are sensitive to strong alkali. [0005] In the traditional polyester fabric dyeing and finishing process, the pretreatment desizing, refining and ...
