Color.In addition, since this method is to textile one-bath process, it is possible to existing step when effectively avoiding using two bath process
The problem of rapid complicated and waste water resource.
The second embodiment of the present disclosure provides a kind of textile dyeing method, as shown in Fig. 2, this method comprises:
Textile to be contaminated is placed in the dye liquor as made of default dyestuff configuration by step S201 at the first temperature, should be to
Dye textile is formed by the fiber interweaving of at least two types, which includes the dye of positive ion and acid dyes.
In one possible implementation, being somebody's turn to do textile to be contaminated can be by Cationic Dyeable Pet fiber, polyamide fibre
(polyamide, PA) fiber and ordinary polyester (polyethylene terephthalate, PET) fiber interweaving form.Its
In, which may include the dyeable modified terylene of high pressure cation (cationic dyeable
Polyester, CDP) fiber, normal atmosphere cation-dyeable modified dacron (atmospheric pressure cationic-
Dyeable polyester, ECDP) fiber and novel normal atmosphere cation-dyeable modified dacron (novel atmospheric
Pressure cationic-dyeable polyester, NECDP) fiber.Wherein, NECDP is also commonly known as the dye of positive ion
Normal pressure can contaminate new modified terylene or novel cation dyestuff dyeing at normal pressure terylene.
Ordinary polyester often has the characteristics that high-modulus, high intensity, elasticity and conformality are good, not wrinkled, is weaving work
Common a kind of textile material in industry.But ordinary polyester, which often only has, the ester group of hydrogen bond is formed with disperse dyes, and lack
It is weary can be with the functional group of the combinations such as direct dyes, acid dyes or basic dye.Again since the crystallinity of ordinary polyester is high, structure
Closely, dye molecule is difficult to enter the fibrous inside of ordinary polyester, so causing to dye ordinary polyester difficult.Therefore, right
When the textile as made of the fiber blend of ordinary polyester fiber and other easy dyeings is dyed, ordinary polyester tend not to by
Dyeing is by slight stain.
By the way that ordinary polyester and dyeing terylene modifying agent (for example, Sodium Dimethyl Isophthalate-5-sulfonate etc.) are copolymerized,
Sulfonate groups can be introduced in terylene strand, so as to which ordinary polyester is changed into Cationic Dyeable Pet.Pass through
Change the raw material proportioning and reaction condition (for example, temperature and pH value etc.) of ordinary polyester and dyeing terylene modifying agent, can incite somebody to action
Ordinary polyester is changed into CDP, ECDP and NECDP.Wherein, the difference of NECDP and ECDP is to make during producing them
There is difference in dyeability modifier, and there is also differences for production technology.NECDP and sulfonate groups contained in ECDP fiber
Quantity it is different, and (fibre section of NECDP is cross, and ECDP there is also different for NECDP and the fiber cross section of ECDP
Fibre section be circle).
There is difference in the quantity of the sulfonate groups as included in the fiber of CDP, ECDP and NECDP, even if
It is that these three Cationic Dyeable Pets are placed under identical dyeing circumstances, what these three Cationic Dyeable Pets were finally presented
Color is also not exactly the same.Wherein, when being dyed using identical colouring method to these three Cationic Dyeable Pets,
CDP fiber is often presented light color, ECDP fiber often present in color, and dark color is often presented in NECDP fiber.It needs to illustrate
It is that light, middle color and dark color herein refers to same colour system gradation of color, and the difference of light color, middle color and dark color
Often can be by visually judging, or can also be judged by colorimetric card.
Treat dye textile dyed when, better coloring effect, can select the fiber of light color to hand in order to obtain
It knits to obtain the textile to be contaminated.For example, the textile to be contaminated can be obtained using the fiber interweaving of white.In addition, if selected
The fineness of fiber is smaller, then can be weaved by the way of preparing when contaminating textile using double joint yarn.
When dye textile dyes, the dye liquor pair as made of the dye of positive ion and acid dyes configuration is being selected to this
Textile to be contaminated is somebody's turn to do to be dyed.Wherein, the dye of positive ion can select that disperse type cationic dye SD-GRL is red, distributed sun
Ionic dye SD-5GL is yellow and/or disperse type cationic dye SD-BL is blue, acid dyes can select active red, active yellow and/
Or reactive blue.It should be noted that in practical applications, other dyes of positive ion and acid can also be selected according to the actual situation
Property dyestuff.
The dosage of the dye of positive ion and the dosage of acid dyes can be selected according to the actual situation, or can also be right
Textile to be contaminated first does staining experiment to each fiber for forming the textile to be contaminated before being dyed, by testing and judging each fibre
K/S value under the conditions of different dyes dosage is tieed up, so as to select a kind of suitable dye dosage.In general, K/S value
The amount of the bigger dyestuff for illustrating fiber absorption is more, and the color of fiber surface is deeper, and the degree that fiber is contaminated is also deeper, and K/
S value is smaller, illustrates that the amount for the dyestuff that fiber absorbs is fewer, and the color of fiber surface is more shallow, and the degree that fiber is contaminated also is got over
Shallowly.
In addition, treat dye textile dyed when, textile enter bath temperature (i.e. the first temperature) can also basis
Actual needs is configured.It in one possible implementation, can be according to the K/S value of each fiber in different balneation temperature strips
Situation of change under part suitably enters bath temperature to be arranged.It also needs in view of subsequent to being made of textile to be contaminated and dye liquor
System heats up, therefore can be greater than room temperature, to save the time used in subsequent heating by the first temperature setting.For example,
It can be 45 DEG C -60 DEG C by the first temperature setting.
The dyeing system being made of textile to be contaminated and dye liquor is warming up to the second temperature with the first heating rate by step S202
Degree, and kept at the first time at second temperature.
After being placed in textile to be contaminated as made of the dye of positive ion and acid dyes configuration in dye liquor, in order to make to contaminate
Dyestuff in liquid gives full play to coloration, needs to heat up to the dyeing system being made of textile to be contaminated and dye liquor.By
It often differs larger with the optimum dyeing temperature of the dye of positive ion in acid dyes, therefore, is risen to the dyeing system
Wen Shi, needs to be heated up twice, i.e., being first warming up to second temperature makes to be suitable for that the lower acid dyes of dyeing temperature first treats dye
Textile is dyed, be then warming up to again third temperature make the dye of positive ion treat dye textile dyed.
Since the suitable dyeing temperature of acid dyes is often below the suitable dyeing temperature of the dye of positive ion, and temperature is excessively high
When often destroy the activity of acid dyes, therefore in step S202, which should not be warming up to excessive temperature.In
In a kind of possible implementation, using active red, active yellow and/or reactive blue as acid dyes mainly to polyamide fibre progress
When dyeing, second temperature can be set to 65 DEG C -80 DEG C.Preferably, second temperature can be set to 70 DEG C.By first
When temperature is warming up to second temperature, temperature jump causes acid dyes to inactivate in order to prevent, can use a stable heating
The dyeing system is warming up to second temperature from the first temperature by rate (the first heating rate).For example, the first heating rate can be with
For 1 DEG C/min-2 DEG C/min.Preferably, the first heating rate can be 1 DEG C/min.
After the dyeing system is warming up to second temperature, in order to react acid dyes sufficiently with textile to be contaminated,
It is sufficiently dyed in order to treat dye textile, which can be kept into for the regular hour (i.e. at second temperature
At the first time).The specific duration of first time can be selected according to actual needs, for example, can be at the first time 5min-
15min.It preferably, at the first time can be 10min.
The dyeing system being made of textile to be contaminated and dye liquor is warming up to third temperature with the second heating rate by step S203
Degree, and kept for the second time at third temperature.
As described above, make acid dyes treated under preference temperature dye textile dyed after, it is also necessary to by this
Dyeing system is warming up to third temperature, so that the dye of positive ion is treated dye textile under preference temperature and dyed.In one kind
In possible implementation, using disperse type cationic dye SD-GRL is red, disperse type cationic dye SD-5GL is yellow and/or
When disperse type cationic dye SD-BL indigo plant mainly dyes above-mentioned three kinds of Cationic Dyeable Pets as the dye of positive ion,
In view of the suitable dyeing temperature of the dye of positive ion is usually higher than the suitable dyeing temperature of acid dyes, therefore can be by third temperature
Degree is set as 85 DEG C -100 DEG C.When second temperature is warming up to third temperature, a stable heating rate can also be used
The dyeing system is warming up to third temperature from second temperature by (the second heating rate).For example, the second heating rate can be 1
℃/min-2℃/min.Preferably, the second heating rate can be 1 DEG C/min.
After the dyeing system is warming up to third temperature, in order to keep the dye of positive ion abundant with Cationic Dyeable Pet
Reaction is sufficiently dyed in order to treat dye textile, when which can be kept to certain at third temperature
Between (i.e. the second time).The specific duration of second time can be selected according to actual needs, for example, the second time can be
20min-60min。
The dyeing system being made of textile to be contaminated and dye liquor is cooled to the 4th temperature by step S204.
It generally requires to wash the textile that dyeing is completed after the completion of to textile dyeing, wash in order to prevent
Occurs safety problem in the process, so needing that the temperature of the dyeing system is first down to the 4th temperature.The specific number of 4th temperature
Value can be selected according to actual needs, for example, can be 65 DEG C -75 DEG C by the 4th temperature setting.It preferably, can be by
Four temperature settings are 70 DEG C.During cooling, in order to prevent sudden temperature drop and lead to that fine wrinkle occurs in textile or feel is thick
The problems such as rough, it is possible to be cooled down using stable rate of temperature fall.For example, the drop of 1 DEG C/min-2 DEG C/min can be used
Warm rate.It preferably, can be using 2 DEG C/min as rate of temperature fall.
The destruction furthermore, it is contemplated that dyestuff can be decomposed under the conditions of high-temperature alkaline, and terylene is easy under the conditions of high-temperature alkaline
It is damaged, and when pH value is too low, will affect the dye-uptake of dyestuff, so using colouring method pair provided in this embodiment
It, can be by the pH stable of the dyeing system in 4-6 when textile is dyed.Wherein it is possible to using glacial acetic acid and sodium acetate
Adjust the pH value of the dyeing system.

The dosage of material can be infected with NECDP fiber when being greater than 2% (o.w.f).It is therefore possible to use no more than 2% (o.w.f) dosage
Acid dyes dyes above-mentioned textile to be contaminated.Preferably, the dosage of acid dyes can be set to 1.5% (o.w.f).
It, can be according to three kinds of Cationic Dyeable Pets in Fig. 3-5 under the conditions of different dyes dosage for the dosage of the dye of positive ion
K/S value is set.It, can in order to avoid wasting raw material while guaranteeing dyeing quality (i.e. 95% or more dyeing percentage of raising)
To set 2% (o.w.f) for the dosage of the dye of positive ion.It, can be in addition, when the bath raio wait contaminate textile and dye liquor is arranged
It is selected according to the actual situation.For example, 1:40-60 etc. can be set by the bath raio of textile to be contaminated and dye liquor.It needs
It is bright, although the present embodiment be done staining experiment for homogencous dyes, it will be appreciated by those skilled in the art that if
Dye textile is treated using two or more the dye of positive ion or acid dyes to be dyed, then can also will mix
The dosage of the dye of positive ion be set as 2% (o.w.f), set 1.5% (o.w.f) for the dosage of mixed acid dyes.
When doing staining experiment to above-mentioned five kinds of fibers, dye dosage unitary variant can be made, other experimental variables
