1. batch preparation has a method for the superpower toughness fiber of imitative clam shell feature and helical structure simultaneously, it is characterized in that described method step is as follows:

  • One, Two-dimensional Inorganic nanometer sheet mixed by a certain percentage with polymer, obtain the stoste as wet spinning silk, the mass fraction controlling Two-dimensional Inorganic nanometer sheet in stoste is 0 ~ 100%;

    Two, the stoste obtained in step one is moved in the container of 1 ~ 25mL, be the spinning pin hole of 10 ~ 500 μ

    m by internal diameter with the extruded velocity of 0.1 ~ 100mL/h, the stoste extruded enters in condensation water solidifies 0.5 ~ 15min, again the fiber solidified is taken out, wash 3 ~ 5 times, and in 50 ~ 80 DEG C of baking ovens dry 12 ~ 24h, obtain the Two-dimensional Inorganic nanometer sheet/polymer fiber with imitative clam shell feature;

    Three, fiber step 2 obtained is weaved in dry spinning equipment, adjustment moment of torsion is 0.001 ~ 10N/m, axial tension 0.1 ~ 50N, weaving 10 ~ 120min, form the fiber with continuous helical structure, so far, the Two-dimensional Inorganic nanometer sheet/polymer fiber simultaneously with imitative clam shell feature and helical structure is obtained.
