[0046] The main components of the modified polyurethane color fixing agents A to D are shown in Table 1.
[0047] The composition of table 1 modified polyurethane color fixing agent
[0048]
[0049] The concrete preparation process of modified polyurethane color fixing agent A is as follows:
[0050] S1. The dehydrated polyethylene glycol and isophorone diisocyanate were reacted together under the action of bismuth laurate for 2 hours, and then N-methyldiethanolamine was added for chain extension reaction for 2 hours to generate a terminal group of -NCO Polyurethane; the reaction temperature is 90°C;
[0051] S2. After the reactant is cooled to 50°C, add 2-(2-hydroxy-4-aminophenyl)hydrobenzotriazole for capping, and react for 1 hour; use acetone to reduce the viscosity during the polymerization process;
[0052] S3. Add deionized water and emulsify for 40 minutes at a stirring speed of 800r / min; remove acetone by vacuuming to obtain modified polyurethane color fixing age...

Abstract
The invention discloses a printing ink compound and an application thereof in cotton printing. The printing ink compound comprises a water-based reactivedye ink A and a printing sizing agent B, wherein the water-based reactivedye ink A comprises 2-15% of P-type active dye, 2-8% of cationic fixing agent, a functional auxiliary and a solvent; the cationic fixing agent is formed by a dispersion phase and a solid phase; water is taken as the dispersion phase; the solid phase is prepared by adopting the following materials by weight percent: 32-63% of polyhydric alcohol, 16-38% of diisocyanate, 4-8% of cation chain extender, 11-29% of amino-containing ultraviolet ray absorber and 0.1-0.2% of catalyst; the printing sizing agent B is prepared from the following components by weight percent: 1-15% of printing paste, 1-10% of burnishing paste, 2-8% of sodium bicarbonate, 1-8% of urea and the balance of deionized water. The printing product made from the printing ink compound has the advantages of high color fixation rate, high light fastness, high crocking fastness, no bleeding phenomenon, high sizing agent releasing rate and no influence on fabric hand feeling.
Description
technical field [0001] The invention relates to the technical field of cotton inkjet printing, in particular, the invention relates to a printing ink composition and its application in cotton printing. Background technique [0002] Reactive dyes have the characteristics of bright color, complete chromatogram, low production cost, high color fastness, simple application process, and no carcinogenic groups in structure. Since their introduction in 1930, they have maintained a huge advantage in cotton printing. However, traditional reactive dye printing not only has a low color fixation rate, but also has high salt and urea in the printing and dyeing process, which is not environmentally friendly. In addition, when the reactive dye is excited by lower-energy visible light, it will undergo photooxidative fading with oxygen in the environment, and its resistance to sunlight is poor. Therefore, improving the color fixation rate of reactive dyes while maintaining their reactivity ...
