Description
Technical field
The invention belongs to technical field of textile printing more particularly to a kind of nylon fabric reactive dyeing processing methods.
Background technique
Polyamide fibre (polyamide) has good intensity and toughness, excellent wearability and resilience.Nylon fibre macromolecular
Contain a large amount of amide groups in chain, there are amino and carboxyl in both ends, and therefore, polyamide fibre can be contaminated with weak acid dye and neutral dye
Color.Weak acid dye dye polyamide fibre can get bright-coloured color, but when contaminating darker pool, wet to rub and soap that be stained with bright and beautiful fastness poor；In
Property dyes polyamide fibre depth it is good, dye utilization rate is high, is easy to contaminate to obtain deep heavy colour pool, and dyefastness is excellent, especially day
Shine fastness.The disadvantage is that coloured light withers secretly, color is not bright-coloured.
Disperse dyes contaminate polyamide fibre good level-dyeing property, to uneven dyeing phenomenon caused by polyamide fibre quality discrepancy, have good
Covering.The disadvantage is that: (1) depth poor, it is difficult to contaminate to obtain deep heavy colour pool, can only contaminate in light color.(2) color is not gorgeous enough, contaminates product
Coloured light luminance range.(3) under high temperature dry heat condition, thermal mobility is big, deep-colour fabric wet friction and soaps in dye and is stained with bright and beautiful fastness
Difference, especially light fastness are generally reduced compared with terylene, and many dye species are not available even.(4) with dye terylene phase
Than many disperse dyes contaminate polyamide fibre, can generate coloured light even form and aspect variation, it is impure to obtain color.
Nylon fibre is contaminated on reactive dye, other than generating ionic bond by the ammonium of polyamide fibre molecular end and combining, dyestuff
More stronger Van der Waals force and hydrogen bond can also be generated between fiber, this is to raising reactive dye on the suction color of nylon fibre
Dye rate, increase color depth plays an important role.Reactive dye dye polyamide fibre obtains that color is more bright-coloured, and wet friction and soaping fastness are good,
Light fastness in addition to certain navy blues, black dyes are poor, it is most of it is common in Resist Reactive Dyes it is all preferable, and can be with
Acid, neutral, disperse dyes mutually spell dye.Therefore, polyamide fibre is contaminated using the good reactive dye of dyeing effect, neutral dye can be made up
Color withers secretly, and partially acidic dyestuff fastness to wet rubbing and light fastness it is poor, disperse dyes thermal mobility is big, poor color fastness and
The deficiencies of coloured light is not gorgeous bright enough keeps the colorant match range of dyestuff broader, and chromatography is more complete.
But higher dye-uptake is obtained when in order to dye, traditionally contaminating most of polyamide fibre technique is under the high temperature conditions
It carries out, reactive dye are no exception.Due to the special structure of nylon fabric, it be easy to cause fibrous elasticity to damage under the high temperature conditions
Wound, reduces the ultimate strength of nylon fabric；Meanwhile for the product to obtain high humidity fastness after reactive dyeing, it is necessary to pass through
Cross multiple tracks high-temperature water to wash, sufficiently remove the loose colour on surface, washing process need to consume a large amount of water and the energy, and cause blowdown flow rate and
Pollutional load increases, and increased production cost.Therefore, the novel dyeing of research polyamide fibre is necessary.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of nylon fabric reactive dyeing processing method,
Without carrying out under the high temperature conditions when dyeing, the washing temperature after dyeing can also be reduced, and washing dosage can also be reduced.Full
While sufficient nylon fabric dye level and color fastness, nylon dyeing energy consumption, water consume and production overall cost is greatly reduced.
A kind of nylon fabric reactive dyeing processing method of the invention, the specific steps are as follows:
(1) according to contaminated nylon fabric weight and color depth, a certain amount of reactive dye is weighed and are dissolved in a small amount of water,
After dyestuff is completely dissolved, according to dye bath ratio 1:5~1:30, the dyeing system that nonaqueous solvents is mixed with water is prepared, wherein non-
The percentage by volume of aqueous solvent is 70%~90%.
The type of reactive dye can be a chloro-s-triazine class, vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) class either one chloro-s-triazine/vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) combination
Class；Reactive dye are minimum insoluble in nonaqueous solvents or solubility.
The boiling point of nonaqueous solvents is lower than aqueous solution, can be miscible with water, preferred alcohol, acetone.
(2) pH value 4~5 that dyeing system is adjusted with glacial acetic acid, puts into nylon fabric, then with the speed of 1~2 DEG C/min
Be warming up to 50~60 DEG C and keep the temperature 20~40min, then with the speed of 1~2 DEG C/min be warming up to 60~80 DEG C and keep the temperature 30~
75min.Heat preservation end poststaining residual night is emitted into fixed reclaimer.
(3) will be by sufficiently cleaning after dyed fabric, to obtain high humidity fastness, cleaner bath ratio is 1:5~1:20.Dyeing brocade
Synthetic fibre fabric first passes through one of cold water and washes, and 5~15min of time is handled, then with the assembly containing soaping agent, nonaqueous solvents and water
System, wherein soaping agent dosage is 0.5~2g/L, and the percentage by volume of nonaqueous solvents is 30%~50%, in 70~80 DEG C of conditions
Nylon fabric is handled after lower dyeing, 10~20min of time, by residual liquid discharge into solvent recovery unit, then with containing
The combined system of nonaqueous solvents and water, wherein the percentage by volume of nonaqueous solvents is 30%~50%, under the conditions of 50~60 DEG C
Fabric is handled, 5~10min of time, by residual liquid discharge to solvent recovery unit, using one to cold water treatment 5~
15min。
The positive effect of the present invention: the present invention has the advantage that compared with traditional dyeing
(1) present invention carries out dyeing and clear to nylon fabric in the combined system of nonaqueous solvents and water using reactive dye
It washes low temperature dyeing and low temperature soaping, it can be achieved that nylon fabric, easily-recovered organic solvent and recycles, so that having reduces energy
Consumption, water consume, environmental pollution and the effect for reducing production cost.
(2) present invention avoids traditional activated dyestuff high temperature dye polyamide fibre Shi Churan speed by the colouring method of temperature-gradient method
Fastly, the phenomenon that be easy to causeing even dyeing.
(3) present invention cleans fabric after dyeing by the combined system of organic solvent and water, not only by traditional soap
It washes 95 DEG C of temperature and is reduced to 80 DEG C, traditional 80 DEG C of hot water wash are reduced to 60 DEG C, and reduce number 1~2 time of cleaning.
