1. realizing the Yarn spinning method of mixed color based on the coupling drawing-off of dual base color rove, which is characterized in that it is specifically included:

  • 1) drawing-off and twist system include level-one drafting unit, second level drafting unit and the two-component of front and back setting and close twisting listMember;

    2) the level-one drafting unit includes combination rear roller, middle roller;

    Combination rear roller include on same root rear roller axis simultaneouslyArrange the first rear roller and the second rear roller of setting;

    First rear roller and the second rear roller are respectively with linear velocity Vh1And Vh2Rotation;

    Middle roller is with linear velocity VzRotation;

    The the first component rove and the second component rove of first rear roller and the drawing-off of the second rear roller instituteFor the rove of two kinds of different base colors;

    First rear roller is fixed on rear roller axis, and gear or pulley rotation drive firstRear roller movement;

    Second rear roller is rotatably provided on rear roller axis, and drives its rotation by ring;

    3) the second level drafting unit includes front roller and the middle roller;

    Front roller is with linear velocity VqRotation;

    4) the ratio between front roller and middle roller linear velocity V are keptq/VzConstant, size depends on the benchmark line density of yarn;

    5) by adjusting the first rear roller and/or the revolving speed of the second rear roller, while realizing that the online dynamic of yarn ratio is adjustedIt is whole, and then realize the color adjustment of yarn;

    The the first component rove and the second component rove of first rear roller and the drawing-off of the second rear roller institute be respectively magenta,Yellow, cyan, any two kinds in black fiber, if first rear roller and the first component of the second rear roller institute drawing-off are thickThe line density of yarn and the second component rove is respectively ρ

    1And ρ

    2, exported again by front roller and the line for closing the yarns Y obtained after twisting be closeDegree is ρ

    y, then;
