Abstract

The invention discloses a disperse dark-color dye. The disperse dark-color dye comprises the following components in parts by mass: 7-9 parts of a component A, 3-5 parts of a component B, 40-45 parts of a component C, 30-35 parts of a component D and 22-25 parts of a component E. The components are products which have less possibility of contaminating fibers and are applied in dyeing polyester and spandex blended fabrics, reduction washing is not needed on pure polyester, only one alkaline reduction washing is needed on the polyester and spandex blended fabrics to meet the fastness requirement, at least one cylinder of water can be saved, the wastewater discharge is reduced, the dyeing steps are shortened, the dyeing time is decreased, the production cost is reduced and high industrial application value is achieved. During application, the disperse dye composition has the characteristics of good dyeing deepness, good color fastness, excellent lifting power and the like and the dye application cost is well saved.

Description

A kind of dispersion dark dye

Technical field

The present invention relates to disperse dye composition preparation field, particularly relate to a kind of one dispersion dark dye being applicable to terylene and spandex blended fabric dyeing.

Background technology

In recent years; every laws and regulations of environmental protection aspect have been put into effect in every country and area all in succession; China also determines the fundamental state policy economized on resources with protection of the environment; large to energy consumption; the dyeing and finishing industry that blowdown is large is had higher requirement; traditional high fastness DISPERSE DYES is applied to pure dyeing terylene and must washes through reduction at least one times, and application terylene and spandex blended fabric at least need twice reduction to wash just can reach fastness requirement.

Common disperse dark blue in the market mainly contains disperse dark blue 79, disperse dark blue 291 etc., this type of Conventional dye is due to Stability Analysis of Structures, not easy cleaning, cause dyefastness poor, must rely on repeatedly reduction wash fastness just can be made to increase (the reduction mode of washing has two kinds of 1. alkali cleanings: take a policy powder and sheet alkali; 2. pickling: add acidic reduction remover and acetic acid), as reached better fastness, application terylene at least needs once to reduce to be washed; Spandex blended fabric at least needs twice reduction to wash, and this just extends dyeing time, improves cost, adds dyeing waste-water discharge capacity.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of dyeability good, not easily depart from polyster fibre after dyeing, dye mixture is reached exempt to reduce to wash or reduce the dispersion dark dye that number of times is washed in reduction.

For solving the problems of the technologies described above, the technical solution used in the present invention: a kind of dispersion dark dye, by mass fraction, it consists of: component A:7-9 part, B component: 3-5 part, component C:40-45 part, component D:30-35 part, component E:22-25 part;

Described component A, its structural formula (I) is as follows:

Described B component, its structural formula (II) is as follows::

Described component C, its structural formula (III) is as follows:

Described component D, its structural formula (IV) is as follows:

Described component E is sodium methylene bis-naphthalene sulfonate.

Described one dispersion dark dye, by mass fraction, it preferably consists of: component A:8-9 part, B component: 3-5 part, component C:40-42 part, component D:32-35 part, component E:24-25 part.

Described one dispersion dark dye, by mass fraction, it preferably consists of further: component A:8 part, B component: 4 parts, component C:40 part, component D:35 part, component E:25 part.

Tool of the present invention has the following advantages and effect: component is all not easily pollute the product of fiber, it is applied to terylene and spandex blended fabric dyeing, pure terylene is washed without the need to reduction, terylene and spandex blended fabric only need primary alkali reduce to wash and can reach fastness requirement, at least can save a cylinder water, reduce discharge of wastewater, shorten staining procedure, reduce dyeing time, reduce production cost, industrial application value is high.This disperse dye composition has the features such as depth is good, COLOR FASTNESS is good, lifting force is excellent when applying, and contributes to saving dyestuff use cost.

Detailed description of the invention

Be described in further detail in conjunction with specific embodiments, make advantage of the present invention more obvious.Should be appreciated that, content wherein just with explaining, and is construed as limiting protection scope of the present invention absolutely not.The experimental technique of unreceipted actual conditions in the following example, usually conveniently condition, or carry out according to the condition that manufacturer advises.

By above-mentioned quality, each component fully being ground stirs both obtains finished product; The dispersion dark dye that above-mentioned enforcement is obtained carries out performance test, and method of testing is as follows:

Get this finished product 0.5 gram, be scattered in 500 grams of cold water, mix with 32mL water get 8mL after fully stirring after, regulate PH=4.0 with acetic acid, put into 2 grams of polyster fibres to dye, rise to 130 DEG C with the heating rate of 3 DEG C/min, after insulation 30min, be cooled to 80 DEG C, cleaning sampling, obtain black dyeing and weaving thing, without reduction cleaning, adopt GB/T3921-1997, GB/T5718-1997, GB/T3920-1997 method to carry out fastness test, test result is as shown in the table:

Embodiment title	Color	Washing fastness (60 DEG C)	Sublimation reliability (180 DEG C)	Fastness to wet rubbing
					Embodiment 1	Navy blue	4-5 level	5 grades	5 grades
Embodiment 2	Navy blue	5 grades	4 grades	5 grades

Embodiment 3	Navy blue	5 grades	4-5 level	5 grades
					Embodiment 4	Navy blue	4-5 level	4 grades	4-5 level
Embodiment 5	Navy blue	5 grades	4-5 level	4-5 level
					Embodiment 6	Navy blue	5 grades	4-5 level	5 grades

According to above-mentioned test result, dispersion dark dye composition provided by the present invention, without the need to through reduction cleaning on polyster fibre, fastness can reach outstanding representation, shortens staining procedure, reduces dyeing time, and reduce production cost, industrial application value is high.
