Description
Technical field
The present invention relates to textile color fixing agent of a kind of chitosan-containing quaternary ammonium salt and preparation method thereof, belong to textile printing and dyeing and help
The research and development and application field of agent.
Background technique
The cellulose base fiber fabrics such as cotton generally use reactive dye and are dyed.Reactive dye chromatography is complete, bright-colored,
On dyed fabric, reactive dye with cellulose fibre can form covalent bond and fixed, thus with good color fastness
Energy.But reactive dye belong to hydrophilic type dye, there are the hydrophilic radicals such as sulfonic group in molecular structure, due to this hydrophilic
The presence of group, and due also to the covalent bond of dyestuff and fiber can be due to hydrolysis in the processing and use process of fabric
Scission of link occurs, so that the fastness properties of dyeing (especially dark) fabric are not ideal enough.
Carrying out fixation using cationic fixing agent is the effective ways for improving cotton fabric by utilizing reactive dye dyefastness.Cation
Color fixing agent is mostly the high-molecular compound of quaternary ammonium salt, and by fixation treatment, color fixing agent can be formed on the fabric with cation
The resin of group, quaternary ammonium salt cationic group in molecular structure can with the yin such as sulfonic group in the dye molecule on fiber from
Subbase group forming salt bond, which is closed, generates color lake, the water solubility of dye molecule is effectively reduced, to improve the color fastness of dyed fabric.
Chitosan quaternary ammonium salt can be used as color fixing agent as a kind of cation high molecular object made of natural material, can be with
Anionic dye effect, is effectively reduced the water solubility of dyestuff and obtains colour fixation.Chitosan quaternary ammonium salt have it is nontoxic, harmless,
Advantages are easily biodegradable etc., its application study in terms of color fixing agent is concerned.
Chitosan quaternary ammonium salt is obtained by chitin modified, the chitosan as its raw material by the amino in molecular structure and
It can dissolve, but cannot be dissolved in neutral or alkalinity water in acidic aqueous media, even if its water solubility in acid condition
It is very limited.The chitosan quaternary ammonium salt of chitin modified acquisition, introduces cationic quaternary ammonium salt groups in molecular structure, water-soluble
With enhancing, but the solubility in its water is still lower, and the water-soluble liquid (especially under neutrality to alkaline condition) of higher concentration is in muddy
Turbid opaque appearance, chitosan quaternary ammonium salt it is this water solubility on defect, to a certain extent to it in textile color fixing agent side
The application in face and commercialized development are construed as limiting.
At present also there is technology chitosan quaternary ammonium salt being applied in color fixing agent, if publication date is on 04 09th, 2014,
In the Chinese patent of Publication No. CN103709364A, a kind of Quaternary Ammonium Salt of Chitosan and the composite modified cation of organosilicon are disclosed
The preparation method of water-borne polyurethane color fixing agent, but the complex process of the preparation method.For another example publication date is 04 month 2015 29
Day, in the Chinese patent of Publication No. CN104562803A, disclose a kind of fabric color fixing agent, it is difficult to effectively improve solid color
Energy.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and one kind is provided with chitosan quaternary ammonium salt
