[0027] The preparation method of a cationic formaldehyde-free color fixing agent of the present invention is realized through the following steps:
[0028] (1) Put a certain amount of water and chitosan quaternary ammonium salt into a four-necked reaction flask, and heat it to 85-120°C with an oil bath under the protection of nitrogen;
[0029] (2) Add dropwise the mixed solution of 6-allylamino n-hexyltrimethylammonium chloride, sugar-containing monomer and water respectively, and add dropwise the initiator solution whose mass concentration is 1%~3% in addition, this initiator The solution is prepared from the initiator and water;
[0030] (3) Control the mixed solution of 6-allylamino n-hexyltrimethylammonium chloride, sugar-containing monomer and water and the initiator solution to add simultaneously, and the dropping time is controlled at 3 to 6 hours;
[0031] (4) After the dropwise addition, keep the temperature and continue the reaction for 1 to 3 hours, then cool down...
