Embodiment 1
[0024]A method for dyeing cotton fiber with indigo-sodium alginate microspheres, comprising the following steps:
[0025](1) Preparation of indigo-sodium alginate composite microspheres: Dissolve 1 part of sodium alginate in 100 parts of deionized water at 80°C for later use; add 1.7 parts of indigo dye to the sodium alginate aqueous solution and stir and mix thoroughly; Dissolve 1 part of anhydrous calcium chloride in 100 parts of deionized water, slowly and evenly drop the indigo-sodium alginate mixed solution into the calcium chloride fixing solution, react for 60 minutes, and wash 4 times with deionized water after the reaction is completed; The prepared product is dried for use;
[0026](2) Pretreatment of cotton fiber: Weigh 1g refined cotton fiber, use a brush to smooth the looseness, put it into deionized water to soak and swell, control the liquid-carrying rate of cotton fiber to 120%, and prepare for dyeing;
[0027](3) Preparation of reducing solution: using the full bath reductio...
Embodiment 2
[0032]The difference from Example 1 lies in the following: the preparation of indigo-sodium alginate composite microspheres in step (1) is different, as follows: 2 parts of sodium alginate are dissolved in 100 parts of deionized water at 80°C for use; Add 2 parts of indigo dye to the sodium alginate aqueous solution and mix thoroughly; dissolve 3 parts of anhydrous calcium chloride in 100 parts of deionized water, slowly and uniformly drop the indigo-sodium alginate mixed solution into the calcium chloride fixing solution , React for 60 minutes, wash 4 times with deionized water after the reaction is completed; the prepared product is obtained after freeze-drying treatment. Other conditions are the same as in Example 1.
Embodiment 3
[0034]The difference from Example 1 is that the process recipe for preparing indigo-sodium alginate composite microspheres in step (1) is different, as follows: 3 parts of sodium alginate are dissolved in 100 parts of deionized water at 80°C for use; Add 2.5 parts of indigo dye to the sodium alginate aqueous solution and stir and mix thoroughly; dissolve 3 parts of anhydrous calcium chloride in 100 parts of deionized water, slowly and uniformly drop the indigo-sodium alginate mixed solution into the calcium chloride fixing solution , React for 60 minutes, wash 4 times with deionized water after the reaction is completed; the prepared product is obtained after freeze-drying treatment. Other conditions are the same as in Example 1.
