Embodiment 1

[0031] Mix 30 parts by weight of component A of formula (I-1) and 70 parts by weight of component B of formula (II-2) through a blending machine for dry powder mixing to obtain composition 1, which is used as reactive yellow dye , Can dye cotton fabric into golden yellow.

[0032]

Embodiment 2

[0034] Dissolve 90 parts by weight of component A of formula (I-5) and 10 parts by weight of component B of formula (II-2) in water, stir uniformly, and dry in a drying room to obtain composition 2. As a reactive yellow dye, it can dye cotton fabrics into golden yellow.

[0035]

Embodiment 3

[0037] Mix 25 parts by weight of component A of formula (I-5), 25 parts by weight of component B of formula (II-10), and 50 parts by weight of sodium sulfate through a mixing machine to dry powder mix to obtain composition 3. As a reactive yellow dye, the composition can print and dye cotton fabrics into golden yellow.

Abstract

The invention provides a composition which comprises the following components in parts by weight: 15 to 90 parts of a component A shown by a formula (I), 10 to 70 parts of a component B shown by a formula (II), and 0 to 50 parts of an auxiliary agent. When used as an active yellow dye, the composition provided by the invention has the advantages of bright color, high improving capacity and degreeof fixation, good leveling property, good dyeing stability and excellent color fastness.

Description

Technical field [0001] The present invention relates to a composition, especially a reactive yellow dye composition, its preparation method and application. Background technique [0002] As people's requirements for wearing comfort and ecological health are increasing, more and more textile products are concentrated on cotton fabrics, and the demand for reactive dyes has also increased, becoming one of the most widely used synthetic dyes. [0003] How to make dyes have higher fixation rate and lifting power has become one of the current development directions of reactive dyes. Because of the high lifting power, the amount of dye used in high-dyeing depth printing and dyeing is relatively reduced, and the high fixation rate can shorten the soap elution process in the traditional fiber dyeing process, thereby shortening the entire printing and dyeing time, thereby reducing the dyeing cost . [0004] After the single-color dyes are printed and dyed on the fiber, various performance in...
