A kind of color fixing agent for reactive dyeing and preparation method thereof
Technical field
The invention belongs to field of fine chemical, particularly to a kind of color fixing agent for reactive dyeing
And preparation method thereof.
Background technology
Reactive dye are cheap, chromatograph is complete, bright in colour, be widely used in cotton fabric dyeing process.
Although the reactive group in reactive dyestuff molecule is easily combined with covalent bond with fiber, but color fastness is not
Preferable.It is in dyeing course, when particularly dye is dark, often occurs because dye strength is too high
Making to exist on dyed fabric the reactive dye of a large amount of non-set, the dyestuff of these non-sets is difficult to from dyeing
Eccysis on fabric, this some dyes will fade in washing process;Meanwhile, some active group is with fine
The chemical bond facile hydrolysis formed between dimension, causes wet colour fastness relatively low.And color fixing agent in early days is as solid
Toner Y is the product of the reactions such as formaldehyde, dicyandiamide and ammonium chloride, although can improve each of product dyed thereby
Fastness, but it is higher to there is content of formaldehyde, and the problem such as be detrimental to health, and has not met the world and has spun
Fabric requirement.Along with constantly expanding and living standards of the people, environmental consciousness of World Textile trade
Improve constantly, to textile comfortable, cleaning, safety etc. index propose higher requirement.
Since entering 21 century, World Textile Market fastness every to product dyed thereby proposes higher wanting
Ask, the product dyed thereby after color fixing agent processes, not only to have the soaping of certain grade, wash, rub resistance,
The fastness such as perspiration resistance, sun-resistant, chlorine-resistant drift, but also require without formaldehyde, nontoxic, do not affect and knit
Thing feel and complexion changed etc..Therefore, research meets ecological, environmental protective, formaldehydeless new reactive dyes with solid
Toner is a significant job.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of for reactive dyeing
Color fixing agent and preparation method thereof, this color fixing agent can more preferably improve fabric fastness to wet rubbing and washable color jail
Degree.
To achieve these goals, the present invention is by the following technical solutions:
A kind of color fixing agent for reactive dyeing, including the raw material components of following portions by weight proportioning:
Described imidazoles villaumite is 1-pi-allyl-3-Methylimidazole. villaumite, 1-pi-allyl-3-ethyl imidazol(e) chlorine
Any one in salt, 1-pi-allyl-3-hexyl imidazolium villaumite, 1-pi-allyl-3-octylimidazole villaumite
Or it is two or more with any mixture than mixing.
Described acid regulator be described acid regulator be any in citric acid, tartaric acid, acetic acid
One or more are with any mixture than mixing.
Described initiator be any one or two kinds in Ammonium persulfate., sodium peroxydisulfate and potassium peroxydisulfate with
On with any than mixing mixture.
The preparation method of a kind of color fixing agent for reactive dyeing and preparation method thereof, by as follows
Step realizes:
(1) equipped with thermometer, agitator, reflux condenser reactor in be sequentially added into described miaow
Azoles villaumite monomer, acrylic acid trifluoro second fat, dihydroxy ethyl diallyl ammonium chloride, acid regulator,
Open reflux condensation mode, stirring after deionized water, and begin to warm up intensification;
(2), when temperature rises to 85~100 DEG C, then starting to drip mass percent concentration is 1~10%
Initiator solution, this initiator solution is formulated by the described deionized water of described initiator and part;
Time for adding controls at 0.5~3 hour, and during dropping, temperature controls at 85~100 DEG C;
(3) insulation reaction 1~5 hours again after adding, be subsequently added into the water of surplus, and stirring 0.5 is little
Discharging time after, obtains described color fixing agent.
Compared with prior art, the present invention has a following remarkable result:
1, by introducing imidazole group, hydroxyl, aliphatic radical, halogen isoreactivity group so that preparation
Color fixing agent in use, color fixing agent molecule and dyestuff, fiber molecule active group (as hydroxyl,
Amino etc.) crosslink combination production color lake (fixation), reduce the dyestuff affinity to water,
Improve the effects such as wet colour fastness such as the soaping of dyed fabric, staining.Additionally, molecule has quaternary ammonium
Salt cation group, by the moon such as the sulfonic groups of cation base and reactive dye (including its hydrolised dye)
, there is Coulomb attraction effect in ion, neutralizes its electric charge, reduces the water solublity of dyestuff, and cloudy with dyestuff
Ions binding, increases the active force between dye molecule and fiber molecule, to improve wet fastness.
2, the formaldehydeless pollution of prepared color fixing agent, effectively reduces fabric formaldehyde content, promotes fabric
Quality, meet the health demand of environmental requirement and the people, there is wide market prospect.
