1. a cooling forming method for melt spinning, is characterized in that, comprises the following steps:

  • (1) polymer melting;

    (2) pass through spinning manifold;

    (3) melt spinning that spinnerets thread is extruded is cooling through metal tube cooling device;

    (4) winding shaping;

    Wherein, described metal tube cooling device is a metal tube, this metal tube comprises inside and outside two-layer, the melt spinning that spinnerets thread is extruded is through the cavity of inner layer metal pipe, the heat radiation of strand is on inner layer metal tube wall, and cooling fluid only enters by the entrance of outer layer metal tube, flows out by the outlet of outer layer metal tube, in cavity between inner layer metal pipe and outer layer metal tube, circulate, the cooling that forms Entirely contactless formula is shaped;

    The chilling temperature of described inner layer metal pipe cavity is 0~

    32 DEG C, and coolant temperature is-4~

    28 DEG C.
