Embodiment 1
[0051] Example 1 Preparation of antistatic bio-based nylon 56 fiber.
[0052] (1) Under nitrogen protection, dissolve bio-based pentane diamine in deionized water, gradually add adipic acid, control the molar ratio of adipic acid to bio-based pentane diamine to 1:1.05, and prepare the mass concentration as 50% nylon 56 saline solution. The prepared nylon 56 salt aqueous solution and 2% molecular weight regulator are added into the reactor together, and the pressure is maintained for 2 hours at a temperature of 240°C and a pressure of 1.8MPa. Then release the pressure in the reactor and add 7% antistatic agent PZA. When the temperature rises to 285° C., vacuum is applied to reduce the system pressure to -0.06 MPa, and the system is continuously stirred for 1.5 hours under vacuum to obtain nylon 56 polymer melt. Then it is conveyed into the spinning box through the direct spinning conveying pipeline. In the spinning box, the diameter of the spinneret is 400mm, the number of hole...
