Abstract
The invention discloses a kind of dispersion dark dye, by mass fraction, consisting of: component A:7 9 parts, component B:3 5 parts, component C:40 45 parts, component D:30 35 parts, component E:22 25 parts.Component is all to be difficult to pollute the product of fiber, it is applied to terylene and spandex blended fabric dyeing, pure terylene is washed without reduction, only need primary alkali reduction to wash on terylene and spandex blended fabric and i.e. can reach fastness requirement, at least can save a cylinder water, reduce discharge of wastewater, shorten staining procedure, reducing 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 application, contributes to saving dyestuff use cost.
Description
Technical field
The present invention relates to disperse dye composition preparation field, particularly relate to one and be applicable to terylene and spandex and mix
A kind of dispersion dark dye of textile dyeing.
Background technology
In recent years, the every laws and regulations in terms of environmental protection have been put into effect in every country and area the most in succession, and China is also
Determining the fundamental state policy economizing on resources and protecting environment, big to energy consumption, the dyeing and finishing industry that blowdown is big proposes
Higher requirement, traditional high fastness disperse dyes are applied to pure dyeing terylene have to be through at least one times
Reduction is washed, and applies terylene and spandex blended fabric at least to need twice reduction to wash and can be only achieved fastness requirement.
Common disperse dark blue in the market mainly has disperse dark blue 79, and disperse dark blue 291 etc., this type of is normal
Rule dyestuff due to Stability Analysis of Structures, not easy cleaning, cause dyefastness poor, it is necessary to rely on repeatedly reduction wash
Fastness just can be made to increase, and (the reduction mode of washing has two kinds of 1. alkali cleanings: take a policy powder and sheet alkali；2. pickling:
Add acidic reduction detergent and acetic acid), as reached preferable fastness, application terylene at least needs once also
Former wash；Spandex blended fabric at least needs twice reduction to wash, this just extend dyeing time, improve cost,
Add dyeing waste-water discharge capacity.
Summary of the invention
The technical problem to be solved is: provides a kind of dyeability good, is not easily disconnected from and washs after dyeing
Synthetic fibre fiber, makes dye mixture reach to exempt to reduce and wash or reduce reduction and wash the dispersion dark dye of number of times.
For solving above-mentioned technical problem, the technical solution used in the present invention: a kind of dispersion dark dye, by matter
Amount number, consisting of: component A:7-9 part, component B:3-5 part, component C:40-45 part, component D:
30-35 part, component E:22-25 part；
Described component A, its structure formula (I) is as follows:
Described component B, its structure formula (II) is as follows::
Described component C, its structure formula (III) is as follows:
Described component D, its structure formula (IV) is as follows:
Described component E is sodium methylene bis-naphthalene sulfonate.
Described a kind of dispersion dark dye, by mass fraction, it preferably constitutes as component A:8-9 part,
Component B:3-5 part, component C:40-42 part, component D:32-35 part, component E:24-25 part.
Described a kind of dispersion dark dye, by mass fraction, it further preferably consists of: component A:8
Part, component B:4 part, component C:40 part, component D:35 part, component E:25 part.
The invention have the advantages that and effect: component is all to be difficult to pollute the product of fiber, and it is applied to terylene
Dye with spandex blended fabric, pure terylene is washed without reduction, terylene and spandex blended fabric only need one
Secondary alkaline reduction is washed and i.e. be can reach fastness requirement, at least can save a cylinder water, reduces discharge of wastewater, shortens
Staining procedure, reduces dyeing time, reduces production cost, and industrial application value is high.This disperse dyes group
Compound has the features such as depth is good, color fastness is good, lifting force is excellent when application, contributes to saving dye
Material use cost.
Detailed description of the invention
It is described in further detail in conjunction with specific embodiments, makes advantages of the present invention become apparent from.Should
Understanding, content therein is used merely as explanation, and is construed as limiting protection scope of the present invention absolutely not.Under
The experimental technique of unreceipted actual conditions in row embodiment, generally according to normal condition, or according to maker
Condition proposed by business is carried out.
By above-mentioned quality, each component being fully ground stirs both obtains finished product；Above-mentioned enforcement is prepared
Dispersion dark dye carry out performance test, method of testing is as follows:
Take this finished product 0.5 gram, be scattered in 500 grams of cold water, take after being sufficiently stirred for after 8mL with 32mL
Water mix homogeneously, regulates PH=4.0 with acetic acid, puts into 2 grams of polyster fibres and dyes, with 3 DEG C/min
Heating rate rise to 130 DEG C, insulation 30min after be cooled to 80 DEG C, clean sampling, it is thus achieved that black
Dyeing and weaving thing, without reduction cleaning, use GB/T3921-1997, GB/T5718-1997,
GB/T3920-1997 method carries out fastness test, and test result is as shown in the table:
According to above-mentioned test result, dispersion dark dye compositions provided by the present invention, at polyster fibre
On without through reduction cleaning, fastness i.e. can reach outstanding representation, shortens staining procedure, when reducing dyeing
Between, reducing production cost, industrial application value is high.
