1. a production method for anion BCF fiber, is characterized in that step comprises:

  • A, prepare anion master batch;

    1) fine common BCF poly-raw material section is ground to form to powdery for subsequent use;

    2) fine the common BCF of powdery poly-raw material, nanoscale anion pulvis and auxiliary agent are uniformly mixed;

    3) mixture being stirred carries out granulation, obtains anion master batch;

    B, prepare anion BCF fiber;

    First described anion master batch and the fine poly-raw material of common BCF are mixed to get to mixed material, in mixed material, the percentage by weight of anion master batch is 3%~

    8%;

    Again mixed material is mixed and is expressed in manifold at 220 DEG C~

    280 DEG C temperature;

    Then putting into follow-up BCF spinning production line through the mixed material of manifold produces;

    The production stage of BCF spinning production line is as follows;

    1) spray silk;

    Measuring pump rotating speed is 11~

    16 revs/min;

    2) cooling;

    Lateral blowing is cooling, and wind speed is 0.4~

    1 meter per second;

    3) oil, drawing-off;

    Drawing temperature is 50~

    180 DEG C;

    Preliminary draft roller;

    speed is 850~

    860 ms/min;

    The first drawing roller;

    speed is 893~

    900 ms/min;

    Dominant draft roller;

    speed is 2750~

    2890 ms/min;

    4) BCF bulking;

    130~

    200 DEG C, pressure is 6~

    9bar;

    5) cooling and shaping, output, entanglement network, coiling.
