CN104231669A - Composite active brown dye - Google Patents

Abstract

The invention discloses a composite active brown dye which is composed of the following components in parts by mass: 18-25 parts of component A, 16-18 parts of component B, 15-22 parts of component C, 5-8 parts of component D, 10-12 parts of component E and 3-4 parts of component F. The composite active brown dye belongs to a moderate-temperature type when being used for dyeing the cellulose fiber material, has approximate dye-uptake curve, has approximate affinity, dye-uptake rate and fixation ratio for fibers, and has approximate bath ratio and dyeing temperature sensitivity for electrolyte salts and color fixative alkalis. The composites have excellent dyeing synchronism and leveling property, higher fixation ratio and outstanding dyeing depth, and effectively overcome the defects in the active brown K-B3R, so that the dyeing quality of the cellulose fiber material is ensured.

Description

A kind of composite active palm dye

Technical field

The present invention relates to dye field, particularly a kind of composite active palm dye.

Background technology

Along with the development with staining technique of continually developing of cellulosic fibre kind, when using reactive dyestuffs to dye to cellulosic fibre, more and more higher requirement being proposed to the application performance of reactive dyestuffs, needs the new reactive dyes with excellent properties.The dyestuff of the brown K-B3R structure of existing a kind of similar activity, its solubleness only has 80g/L, produces large amount of sewage in dyeing course.After painted to cellulosic fibre material, its lifting force is inadequate, and level-dyeing property is bad, can not contaminate dark color.

Summary of the invention

The invention provides a kind of composite active palm dye, this composite dye synergistic effect makes it have stable performance, solubleness is high, degree of fixation is high, dyeing synchronism is good, good level-dyeing property, color reproducibility are good, especially there is the advantage that dye is dark outstanding.

For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of composite active palm dye, and according to the mass fraction, it consists of: component A:18-25 part; B component: 16-18 part, component C:15-22 part, component D:5-8 part, component E:10-12 part, component F:3-4 part;

Described component A (I) structural formula is:

The structural formula of B component (II) is:

The structural formula of component C (III) is:

The structural formula of component D (IV) is:

The structural formula of component E (V) is:

The structural formula of component F (VI) is:

Described a kind of composite active palm dye, according to the mass fraction, it preferably consists of: component A:20-22 part; B component: 16-17 part, component C:18-20 part, component D:6-8 part, component E:11-12 part, component F:3-3.5 part.

Prepared by the method for composite active red dye using well known of the present invention.

Composite active palm dye of the present invention, has stable performance, solubleness is high, degree of fixation is high, dyeing synchronism is good, good level-dyeing property, color reproducibility are good, especially the dark outstanding advantage of dye.

Embodiment

The method of the synthesis using well known of each mixture, below in conjunction with embodiment, the invention will be further described, but protection scope of the present invention is not limited thereto.
