Example Embodiment
[0025] Example 1
[0026] Weigh the wool, put it into a wool grinder and grind it for 5 minutes, add the crushed wool to soak in absolute ethanol, filter after soaking for 8 hours, and get the filter residue, put it in an oven, and dry it at 40°C for 8 hours, according to the mass ratio of 1: 10 Add the dried filter residue to a 50% formic acid aqueous solution by mass fraction, crush it with an ultrasonic cell pulverizer for 5 minutes, and obtain a wool mixture, pass the wool mixture through a 160-mesh sieve, and collect the liquid, which is the wool enhancement liquid; In terms of parts, take 10 parts of wool, 8 parts of urea, 40 parts of 5% sodium dodecyl sulfate solution by mass fraction and 40 parts of 3% sodium bisulfite solution by mass fraction, stir and mix them and put them into the reaction kettle. Heat to 120°C under stirring condition, heat preservation and stirring for 5 hours, then cool to room temperature, discharge the material, filter to obtain the filtrate, ...
