Embodiment 1
[0013] Example 1: The mixed solution is composed of 0.1% sodium hydroxide by mass percentage concentration and 0.1% guanidine hydrochloride by mass percentage concentration, and 10 g of acrylic fiber is added to the mixed solution of 20 times the amount of acrylic fiber. Airtight hydrolysis and cyclization for 200 minutes, take out, wash and dry to obtain high moisture absorption and water absorption acrylic fiber.
Embodiment 2
[0015] The mixed solution is composed of sodium hydroxide with a mass percentage concentration of 1% and guanidine sulfate with a mass percentage concentration of 5%. Take 10g of acrylic fiber and add it to a mixed solution with 15 times the amount of acrylic fiber. After 100 minutes of curing, take it out, wash it and dry it to get high moisture absorption and water absorption acrylic fiber.
Embodiment 3
[0017] The mixed solution is composed of sodium hydroxide with a mass percentage concentration of 5% and guanidine sulfamate with a mass percentage concentration of 10%. Take 10g of acrylic fiber, add it to the mixed solution of 10 times the amount of acrylic fiber, and seal it for hydrolysis at a reaction temperature of 50°C. Cyclize for 60 minutes, take it out, wash it and dry it to obtain high moisture absorption and water absorption acrylic fiber.
