Description
[technical field]
The invention belongs to technical field of textile printing, and in particular to a kind of polyamide fibre black-dyeing at low cost and easily controllable
Process.
[background technique]
It needs to add levelling agent and acetic acid dyeing when existing nylon black-dyeing, dye dosage is big, and auxiliary agent type is more, dyeing
Raffinate is dense afterwards, and water and soaked fastness are more difficult to control, need double solid and multiple fixation, water consumption and energy use cost compared with
It is high.
[summary of the invention]
Object of the present invention is in view of the deficiency of the prior art, provide one kind to reduce auxiliary dosage, save
Water power vapour energy cost, and the polyamide fibre black-dyeing technique side that yields of color and every color fastness all improve a lot
Method.
The technical scheme adopted by the invention is that: polyamide fibre black-dyeing process comprising the step of it is as follows:
(1) pre-treatment: cloth feeding washing；
(2) dye: cloth dyeing, 65-75 DEG C fixation 15-25 minutes；
(3) it wash water fixation: washes, then fixation treatment.
Preferably, the polyamide fibre black-dyeing process comprising the step of it is as follows
(1) pre-treatment: cloth feeding is washed 1 time, 10 minutes；
(2) dye: cloth dyeing, 70 DEG C fixation 20 minutes；
(3) wash water fixation: washing 1 time, time are 10 minutes, then fixation treatment.It is completed because oxyalkylene compound dyes
Raffinate is very clear afterwards, can save wash water twice.
In (1) step, softening agent can be added in water, to improve the flexibility of cloth feeding.
In (2) step, the dyestuff of dyeing is with including the following components'mass percentage:
Described IsolanYellowNHF-S, ISolanRedNHF-S and ISolanBlack2S-LDN are Germany's De Sida collection
The production of company, group.
The oxyalkylene compound can be with polyoxyalkylenated ether carboxylic acid or its salt.The oxyalkylenated ether carboxylic acid is following formula institute
Show compound:
Wherein:
The C8-C22 alkyl or alkenyl of R expression linear chain or branched chain or the mixture of these groups, (C8-C9) alkyl phenyl,
Or R ' CONH-CH2-CH2-, wherein R ' represents linear chain or branched chain C11-C21 alkyl or alkenyl,
N is the integer or score of 2-24,
P is the integer or score of 0-6,
A represents H or Na, K, Li, 1/2Mg or monoethanolamine, ammonium or triethanolamine residue.
Preferably, the oxyalkylenated ether carboxylic acid or its salt can be selected from following formula (I) compound, and wherein R represents (C12-
C14) alkyl, oil base, cetyl or stearyl or these radical mixtures；Nonyl phenyl or octyl phenyl；A represents H or sodium
Atom, p=0, n 2-20, preferably 2-10.
The oxyalkylene compound is the oxyalkylene compound A of Hangzhou Noah chemical company sale.
The oxyalkylene compound dosage optional 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, preferential 1%, oxyalkylene
Compound dosage is few, and color depth is inadequate, and oxyalkylene compound dosage is too many, and color is no longer deepened, and cost will increase, and at cloth
Face is easy to appear auxiliary agent spot.
The oxyalkylene compound is added for 3 minutes in dyeing operation, since oxyalkylene compound pH value is in neutrality, on dyestuff
Color ratio acetic acid mitigates, and does not need the operation long time.
The oxyalkylene compound, which is pressed, presses the linear addition of computer setting in heating, is added the time about 20 minutes, at 80 degree
It added in the past.Oxyalkylene compound is added in low temperature, and cloth cover can play auxiliary agent spot, and oxyalkylene compound adds in high temperature, energy consumption
Greatly, the process time is long, and color is unstable.Oxyalkylene compound is added in heating, and process efficiency and color and cloth cover effect are all
It is best.
In (3) step, fixation heating rate optional 1 DEG C/min, 1.5 DEG C/min, 2 DEG C/min, 2.5 DEG C/min, 3
DEG C/min, preferably 1.5 DEG C/min, heating rate is too fast, and color is easy to appear color difference, and the too slow then process time is long, high expensive.
Be warming up to 98 DEG C heat preservation 20 ', soaking time optional 10 ', 20 ', 30 ', 40 ', 60 ', preferably 20 ', soaking time is too short, and dyestuff is also
Completely upper to contaminate most ideal in 20 minutes colors to the greatest extent, soaking time is long, and at high cost, the process time is long, and dyestuff can also hydrolyze.
Compared with prior art, the invention has the following advantages: reducing auxiliary dosage, water electric energy and gas energy is saved
Cost, and yields of color and every color fastness all improve a lot；In addition yellow is prevented, orchil pollutes ammonia
Synthetic fibre；Cloth face color is uniform, and quality is good；Water stain, soaked fastness significantly improves.
[Detailed description of the invention]
Fig. 1 is conventional process flow schematic diagram；
Fig. 2 is present invention process flow diagram.
[specific embodiment]
Explanation is described in detail to the present invention below in conjunction with specific embodiment.
It contaminates in polyamide fibre black-dyeing process of the present invention and does not need in the process recipe of nylon black with acetic acid+acetic acid
Sodium need to only add the special oxyalkylene compound auxiliary agent of functional aid.Added by technique need to only run after dyestuff can open within 3 minutes as
It is pumped into oxyalkylene compound auxiliary agent, since oxyalkylene compound auxiliary agent pH value is in neutrality, color ratio acetic acid mitigates on dyestuff, does not need
Run the long time.Oxyalkylene compound is added by technique edges heating side by computer setting is linear, is added the time about 20 minutes,
It was added before 80 degree.Oxyalkylene compound is added in low temperature, and cloth cover can play auxiliary agent spot, and oxyalkylene compound adds in high temperature, the energy
Consumption is big, and the process time is long, and color is unstable.Oxyalkylene compound is added in heating, and process efficiency and color and cloth cover are imitated
Fruit is all best.Heating rate optional 1 DEG C/min, 1.5 DEG C/min, 2 DEG C/min, 2.5 DEG C/min, 3 DEG C/min, preferably 1.5 DEG C/
Min, heating rate is too fast, and color is easy to appear color difference, and the too slow then process time is long, high expensive.It is warming up to 98 DEG C of heat preservations
20 ', soaking time optional 10 ', 20 ' 30 ' 40 ', 60 ', preferably 20 ', soaking time is too short, and dyestuff is not also completely upper most, and 20 points
Contaminate most ideal in clock color, soaking time is long, and at high cost, the process time is long, and dyestuff can also hydrolyze.Wash water is only needed after the completion of dyeing
1 time can fixation, because oxyalkylene compound dyeing after the completion of raffinate it is very clear, wash water twice can be saved.Dye overall process only
It can grasp and do by technique requirement, ideal effect otherwise can be not achieved.
Dyeing of the present invention is simple, is mainly the reduction of difference auxiliary dosage, improves colour stability, improves bubble
Water fastness and color fastness is hit, large-scale application after stain colour efficiency and cost all have a distinct increment.
It is as follows with the specific table of comparisons of traditional handicraft:
Process conditions comparison is as depicted in figs. 1 and 2.
