Description
Technical field
The present invention relates to the technical field of weaving more particularly to a kind of indigo dyeing methods.
Background technique
Since existing bipseudoindoxyl dye is not soluble in water, there is no affinity to fiber, be unable to direct staining, it is therefore necessary in alkali
Property solution in reducing agent by indigo reduction at soluble leuco compound, be reoxidised into after being absorbed by fiber insoluble indigo hidden
Colour solid is attached on yarn, achievees the purpose that dye.
And existing bipseudoindoxyl dye be it is artificial synthesized, aniline is one of the raw material of synthesizing indigo dyestuff, it is excessive contain benzene
The bipseudoindoxyl dye of amine can enter in dyeing waste water, and chemical stability is strong, and have the harm such as teratogenesis, mutagenesis, carcinogenic.
The process of indigo dyeing includes indigo reduction, dye, leuco compound oxidation etc. on leuco compound.And in existing indigo dye
It during color, including at least continuous dyeing process more than twice or twice, is washed again after the completion of dyeing, although even
In continuous dyeing process, the color of yarn is gradually deepened, but the color fast degree of yarn is lower.
Therefore, the existing technology needs to be improved and developed.
Summary of the invention
The purpose of the present invention is to provide a kind of indigo dyeing methods, and the dyeing waste water containing aniline can be avoided from source
It generates, and the oxidation effectiveness of dyestuff can be enhanced, improve the color fast degree of yarn, make bright in luster, reduce the cost of dyestuff.
Technical scheme is as follows:
A kind of indigo dyeing method, comprising the following steps:
Indigo dyeing process: yarn is subjected to indigo dyeing；Bipseudoindoxyl dye used in the indigo dyeing process is free of aniline；
The indigo dyeing process sets at least to twice；
Washing step is equipped between wherein two adjacent indigo dyeing processes.
The indigo dyeing method, wherein the temperature of the washing step is 30 DEG C ~ 90 DEG C.
The indigo dyeing method, wherein the temperature of the washing step is 60 DEG C.
The indigo dyeing method, wherein concise process is additionally provided with before indigo dyeing process, the concise process is
High temperature degumming.
The indigo dyeing method, wherein the concise process is set as twice.
The indigo dyeing method, wherein the temperature of the concise process is 95 DEG C.
The indigo dyeing method, wherein per pass indigo dyeing process includes dyeing and oxidation, and yarn is equipped with indigo
It is dyed in the dye vat of dyestuff, the yarn after dyeing is aoxidized in air, and indigo dyeing process carries out in room temperature.
The indigo dyeing method, wherein the dye liquor temperature of the indigo dyeing process is 25 DEG C ± 3 DEG C.
The indigo dyeing method, wherein the indigo dyeing process carries out temperature control by refrigerator.
The indigo dyeing method, wherein after indigo dyeing process further include oil process.
Beneficial effects of the present invention: the present invention can avoid containing aniline from source by providing a kind of indigo dyeing method

The cost of dyestuff.
Detailed description of the invention
When Fig. 1 is using traditional indigo dyeing process, aniline residue amount on the corresponding denim of different washing methods
Dendrogram.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.
The present invention provides a kind of indigo dyeing method, including indigo dyeing process: yarn is carried out indigo dyeing；Indigo dye
Bipseudoindoxyl dye used in color process is free of aniline；Indigo dyeing process sets at least to twice；It is adjacent indigo wherein two
Washing step is equipped between dyeing process.
In traditional indigo dyeing process, it is all made of the bipseudoindoxyl dye containing aniline, as shown in Figure 1, in addition to carrying out chlorine drift
Ultrawhite, other washing methods can not remove the aniline on denim.Since aniline has very strong bio-toxicity, to human body
Harm it is big, the cowboy's textile industry that is produced as of the cloth containing aniline and the waste water containing aniline brings very big puzzlement.
Indigo dyeing of the invention is using the dyestuff without aniline, and patent can be used in this dyestuff without aniline
WO2019030397(A1 in) without aniline dyes.Indigo dyeing process of the invention is shut out from source using no aniline dyes
The generation of aniline waste water absolutely, eliminates the treatment process to aniline waste water, solves the problems, such as that aniline waste water is intractable, this hair
Bright indigo dyeing method is a kind of indigo dyeing method environment amenable, conducive to sustainable development.
Since existing Indigo Dyeing is washed again after continuous multiple tracks dyeing process, by continuous
The color fast degree of the yarn of dyeing is lower, and coloring effect is not good enough, and the present invention is set between wherein twice indigo dyeing process
Washing step is set, the oxidation effectiveness of dyestuff can be enhanced, be attached to bipseudoindoxyl dye preferably on yarn, makes the color fast of yarn
Du Genggao, color is more bright-coloured, to reduce the dosage of dyestuff, reduces production cost.
Further, the temperature of washing step is 30 DEG C ~ 90 DEG C.Preferably, it in order to obtain better colour fixation, washes
The temperature of process is 60 DEG C.
Further, due to containing the substances such as impurity, dirt, leftover slurry, finish, wax in yarn, in order to not influence dye
Color effect is additionally provided with concise process before indigo dyeing process.
Further, reach deimpurity effect since existing concise process needs to be added bleeding agent, make subsequent
It needs to be removed bleeding agent, therefore, concise process of the invention uses high temperature degumming, this high temperature refers to 90 DEG C or more, height
The concise solubility that can improve impurity of temperature, makes concise process it is not necessary that bleeding agent is added, can also be removed to impurity, after eliminating
The continuous processing to residual bleeding agent.
Further, in order to obtain identical as when bleeding agent is added or preferably go deimpurity effect, concise process is set
It is set to twice.
Preferably, the temperature of concise process is 95 DEG C, can obtain preferably go deimpurity effect at this temperature.
Specifically, per pass indigo dyeing process includes dyeing and oxidation, and yarn carries out in the dye vat equipped with bipseudoindoxyl dye
Dyeing, the yarn after dyeing are aoxidized in air, and indigo dyeing process carries out in room temperature.
Specifically, the dye liquor temperature of indigo dyeing process is 25 DEG C ± 3 DEG C.
Further, indigo dyeing process by refrigerator carry out temperature control, make dyeing course at a constant temperature into
Row, dyeing effect more temperature.
Further, for the ease of dividing sinker, the filoplume of yarn is reduced, keeps yarn more smooth, and prevent electrostatic, in indigo dye
It further include oil process after color process.Oil process, which refers to, is immersed in yarn in finish slot, and smooth agent can be used in the finish,
It include smooth agent, antistatic agent etc. in finish slot.Specifically, the temperature of finish slot is 40 DEG C, and soaking time is about 5s.
