Description
Technical field
The invention belongs to textile printing and dyeing fields, are related to a kind of acid dyeing method of wollen fabrics.
Background technology
Cotton is a kind of important native cellulose fibre, has comfortable softness, good hygroscopicity, is not likely to produce electrostatic etc. and is excellent
Wearability, be widely used in manufacture textile fabric, occupy an important position in textile industry worldwide, greatly
Account for about the 65% of fiber total output.Acid dyes has many advantages, such as that bright in colour, chromatography is complete and to the safe of human body,
But since its molecule is smaller, hydrophilic group is more, and water-resistance is poor, not water-fastness, while not having affinity to cellulose fibre, so
It cannot be used for the dyeing of cotton Products.
Wollen fabrics dye the active dyestuff of common dyestuff, direct dyes, reducing dye etc., still, due to cotton fiber
Show elecrtonegativity at typical condition greatly, there are electrostatic repulsions with anionic dye, in traditional dyeing, it is necessary to be added big
The salt of amount promotees the problems such as contaminating, causing environmental pollution and high resource consumption.
Cation group is introduced on cotton fiber and carries out physical or chemical modification, reduces or eliminates the negative electrical charge on fiber,
Dyeing capacity of the anionic dye to cotton is improved, less salt or salt-free dyeing not only may be implemented, and cotton fabric is by cation
After modification so that the same acid dyes with anion can be by contaminating cotton fiber on attractive coulombic force.For example, Yang Shaojun
With the quaternary compound of the group containing chloropharin or there is the quarternary ammonium salt compound of cyanuro in patent CN201129734.4,
Cotton yarn is carried out cation-modified so that the dyeing rate and dye-uptake of reactive dye are improved；Liu Yue is in patent
Pure cotton is knitted as Compositional type cation modifier by using chitosan and quarternary ammonium salt compound in CN201110333645.3
After object carries out composite modified processing, reactive dye can be made to be better than tradition without promoting dye salt or compared with being obtained under low salt concn
The coloring of dyeing；Shen Yong et al. is cation-modified with response type or absorbent-type in patent CN201010195278.0
Agent carries out cation-modified processing to ceiba fiber textiles, also with direct dyes, reactive dye, acid dyes or solubility
Former dyestuff realizes the less salt or salt-free dyeing of fiber to modified stock-dye.But it is special in these existing inventions
In profit, cation modifier used is quarternary ammonium salt compound and chitosan etc., and hand ventilative to the moisture absorption of modified fiber
The performances such as sense can all have a certain impact.
Patent CN103790016A is handled wollen fabrics using cationic polymer nanosphere, by wollen fabrics
Processing is first impregnated or padded with cationic polymer nanosphere solution, is then dyed with acid dyes.So that fibre
It ties up positively charged, by the effect of Coulomb attraction, improves the binding force of acid dyes and cotton, obtain higher dye-uptake.But
The water resistance of its dyestuff, light resistance and wearability are not effectively improved, and dye content does not have yet in waste water from dyestuff
It is significantly improved.
Invention content
In view of the above-mentioned problems, it is an object of the invention to the carbon cation polymerization object nanosphere solution of carboxylated to acidity
Dyestuff is modified, to realize acid dyeing, overcome the water resistance of dyestuff, light resistance and wear no resistance and contaminate
Expect the problems such as Wastewater Dyes content is higher.
Technical scheme of the present invention includes the following steps：
Wollen fabrics are first handled with the carbon cation polymerization object nanosphere solution of carboxylated, then addition is acid
Dyestuff carries out fixation treatment after being dyed.The preparation method method of the carboxylated Nano carbon balls is：By Nano carbon balls and acid
Property solution mixed after be ultrasonically treated, carry out heating condensing reflux after being then allowed to stand immersion, then wash and detach repeatedly
