Embodiment 1
[0014] A preparation method of a cyclodextrin polymer imitating enzyme functional fiber, characterized in that the following steps are adopted:
[0015] A) Cyclodextrin is added to 30% sodium hydroxide aqueous solution at a weight ratio of 1:1, stirred and reacted at room temperature for 10 hours, and then reacted at 40°C according to the moles of cyclodextrin and epichlorohydrin Add epichlorohydrin at a ratio of 1:1 and react for 20 hours. When the reaction reaches the gel point, add an appropriate amount of acetone to stop the reaction, and add absolute ethanol to the solution until a white solid precipitates, filter, and dry in vacuum to obtain a cyclopaste Fine prepolymer;
[0016] B) The cellulose fiber is put into 2% Na by weight ratio of 1:20 2 CO 3 In the solution, react at 70°C for 1 hour, then take it out, wash it, and dry it; put the treated cellulose fiber in a 0.1% NaOH solution at a weight ratio of 1:50 to swell for 2 hours, and take it out;
[0017] C) Put th...

[0022] A preparation method of a cyclodextrin polymer imitating enzyme functional fiber, characterized in that the following steps are adopted:
[0023] A) Cyclodextrin is added to 30% sodium hydroxide aqueous solution at a weight ratio of 1:3, stirred and reacted at room temperature for 15 hours, and then reacted at 30°C according to the moles of cyclodextrin and epichlorohydrin Add epichlorohydrin at a ratio of 1:8, react for 30 hours, when the reaction reaches the gel point, add an appropriate amount of acetone to stop the reaction, and add absolute ethanol to the solution until a white solid precipitates, filter, and vacuum dry to obtain a cyclopaste Fine prepolymer;
[0024] B) The cellulose fiber is put into 2% Na by weight ratio of 1:50 2 CO 3 In the solution, react at 100°C for 3 hours, then take it out, wash it, and dry it; put the treated cellulose fiber in a 0.1% NaOH solution at a weight ratio of 1:10 to swell for 0.5 hours, and take it out;
[0025] C) Put the ...
Embodiment 3
[0030] A preparation method of a cyclodextrin polymer imitating enzyme functional fiber, characterized in that the following steps are adopted:
[0031] A) Cyclodextrin is added to 30% sodium hydroxide aqueous solution at a weight ratio of 1:2, stirred and reacted at room temperature for 13 hours, and then reacted at 35°C according to the moles of cyclodextrin and epichlorohydrin Add epichlorohydrin at a ratio of 1:4, react for 25 hours, when the reaction reaches the gel point, add an appropriate amount of acetone to stop the reaction, and add absolute ethanol to the solution until a white solid precipitates, filter, and dry in vacuum to obtain a cyclopaste Fine prepolymer;
[0032] B) The cellulose fiber is put into 2% Na by weight ratio of 1:35 2 CO 3 In the solution, react at 85°C for 2 hours, then take it out, wash it, and dry it; put the treated cellulose fiber in a 0.1% NaOH solution at a weight ratio of 1:30 to swell for 1 hour, and take it out;
[0033] C) Put the s...
