example 2 4
[0021] Example 2. Tetraacicular zinc oxide whiskers (2.5-7.5 μm in size, not ground) are stirred evenly in N, N-dimethylformamide (DMF), and then a certain amount of polyacrylonitrile and zinc oxide whiskers are added. The weight ratio to polyacrylonitrile is 1%, and then add a small amount of titanate as a coupling agent, stir at 10°C for 30 minutes, gradually heat up while stirring, and stir at 80°C for 4 hours to obtain a spinning stock solution, and then The antistatic acrylic fiber was spun by the spinning process flow of the aforementioned antistatic acrylic fiber, and the sample number was 3.

[0022] Example 3. Tetraacicular zinc oxide whiskers (2.5-7.5 μm in size, not ground) are stirred evenly in N, N-dimethylformamide (DMF), and then a certain amount of polyacrylonitrile and zinc oxide whiskers are added. The weight ratio to polyacrylonitrile is 0.8%, then add a small amount of titanate as a coupling agent, stir at 10°C for 30 minutes, gradually heat up while stirring, and stir at 80°C for 4 hours to obtain a spinning stock solution, and then The antistatic acrylic fiber is spun by the spinning process flow of the aforementioned antistatic acrylic fiber, and the sample number is 4.
example 4 4
[0023] Example 4. Tetraacicular zinc oxide whiskers (2.5-7.5 μm in size, not ground) are stirred evenly in N, N-dimethylformamide (DMF), and then a certain amount of polyacrylonitrile and zinc oxide whiskers are added. The weight ratio to polyacrylonitrile is 1%, and then add a small amount of polyvinylpyrrolidone (PVP) as a dispersant, stir at 10°C for 30 minutes, gradually heat up while stirring, and stir at 80°C for 4 hours to obtain spinning stock solution , and then spun antistatic acrylic fiber according to the spinning process of the aforementioned antistatic acrylic fiber, and the sample number is 5.
