 1. Extraction of wool keratin
 The preparation method is as follows:
 ① Peracetic acid dissolution: wash and dry the wool, and make a peracetic acid solution according to the ratio of peracetic acid: water = 2:1, for the dissolution of wool.
 ② Neutralization with ammonia water: drop ammonia water into the solution, when the pH value of the solution is around 6.0, a light yellow substance will precipitate out.
 ③ Filtration: Filter the solution with a polyester sieve to remove the light yellow substance.
 ④ Dialysis: Put the filtered solution into a dialysis bag, dialyze in running water for 24-48 hours, and filter out small molecules in the solution.
 ⑤ Hydrochloric acid titration: Drop the solution with hydrochloric acid until the pH value is about 4.0. At this time, the pH value is near the isoelectric point of wool keratin...
