[0035]Put silk and cotton into a pulverizer at a mass ratio of 5:1 to pulverize and mix to obtain a mixture, put the mixture and a 5% sodium hydroxide solution into a beaker at a mass ratio of 1:10, and place the beaker in a resistor In the heater, raise the temperature of the heater to 95° C., and let it stand at constant temperature for 3 hours to obtain an alkaline reaction solution. Add dropwise hydrochloric acid with a mass fraction of 3% to the beaker to adjust the pH value to neutral to prepare a prefabricated reaction solution; The above-mentioned prefabricated reaction solution was put into a rotary evaporator, concentrated under the conditions of a rotating speed of 300r / min and a temperature of 70°C until the product quality was constant to obtain a concentrated product, and the concentrated product was mixed with an aluminum chloride solution with a mass fraction of 5% by mass The ratio of 1:10 is put into the reaction kettle, the reaction kettle is sealed, the temp...
