Embodiment 1

[0064] Take 50 parts of the compound of formula (I-1) and 50 parts of the compound of formula (I-2), add 300 parts of water and mix well, then adjust the pH value to 5.5-8.5. After desalination by reverse osmosis to make the salt content less than 0.5% by weight, add 2 parts of the compound of formula (II-1) and stir evenly and adjust the pH value to 6.0-8.5. Finally, spray the solution to dry to obtain the reactive printing dye composition of this embodiment.

Embodiment 2

[0066] Take 100 parts of the compound of formula (I-3), add 300 parts of water and mix well, then adjust the pH value to 5.5-8.5. After purification, 5 parts of the compound of formula (II-1) and 30 parts of mangolin were added and stirred evenly, and the pH value was adjusted to 6.0-8.5. Finally, spray the solution to dry to obtain the reactive printing dye composition of this embodiment.

Embodiment 3

[0068] Take 100 parts of the compound of formula (I-4), add 300 parts of water and mix well, then adjust the pH value to 5.5-8.5. After desalting by reverse osmosis to make the salt content less than 0.5% by weight, add 2 parts of the compound of formula (II-1) and 20 parts of Demol RN, stir evenly and adjust the pH value to 6.0-8.5. Finally, spray the solution to dry to obtain the reactive printing dye composition of this embodiment.

Abstract

The invention relates to a reactive printing dye composition, which comprises: (a) at least one reactive dye; (b) organic buffer; and (c) mirabilite or dispersing agent. The reactive printing dye composition is suitable for fabric dyeing, such as fabrics made with cellulose fibers and other mixed fibers, including cotton, fiber, silk, rayon, wool, blended fibers and the like. In addition, the reactive printing dye composition has good characteristics of high pH stability, good storage stability, improved recession of the dyeing intensity of the dye and the like. Moreover, the invention also provides a liquid reactive printing dye composition.

Description

technical field [0001] The invention relates to a reactive dye composition, in particular to a reactive printing dye composition and / or a liquid reactive printing dye composition, suitable for printing and dyeing cellulose fibers. Background technique [0002] US Patent No. 6,780,229 discloses a dye composition which uses an organic buffer to keep the pH between 4 and 8. U.S. Patent No. 6,015,454 once disclosed a dye composition comprising at least one reactive dye, and 1,2-propylene glycol (1,2-propylene glycol) or N-methyl-2-pyrrolidone (N-methyl-2 -pyrrolidone), which improves the coloring strength and color fixation rate of calico; but the storage stability is not good. U.S. Patent No. 2003 / 0172840 once disclosed a dye composition comprising at least one reactive dye, sulfolane (sulfolane) and a buffer system, which improved storage stability; but chlorine bleaching fastness, dyeing depth (strength) ) and dye solubility are still to be worked on. [0003] Therefore, i...
