Embodiment 1

[0016] Weigh 600 grams of polyamide fiber and dry it at 90°C for 4 hours, then mix it with 80 grams of hydroxypropyl cellulose, 130 grams of polypropylene, 50 grams of γ-aminopropyl triethoxysilane, methyl methacrylate- 50 grams of butadiene-styrene copolymer and 8 grams of monoglyceride stearate were stirred for 5 minutes at 1100 rpm in a high-speed mixer, and released after being uniform. Put the mixed material into the twin-screw extruder with a length-to-diameter ratio (L / D) of 40. The processing temperature of the twin-screw extruder: the temperature in the first zone is 180°C, the temperature in the second zone is 185°C, and the temperature in the third zone is 180°C. The temperature of the fourth zone is 195°C, the temperature of the fourth zone is 210°C, the temperature of the fifth zone is 215°C, the temperature of the sixth zone is 225°C, the temperature of the seventh zone is 235°C, the temperature of the eighth zone is 240°C, and the speed of the main engine is 320 ...

Embodiment 2

[0018] The easily degradable environment-friendly nylon was prepared in the same manner as in Example 1, except that hydroxypropyl cellulose was not used.

Embodiment 3

[0020] Prepare easily degradable environmentally friendly nylon in the same manner as in Example 1, except that polypropylene is not used.
