Embodiment 1
[0022] The production method of the oxygen bar fiber with negative ion function described in this embodiment, the production method of the oxygen bar fiber with negative ion function, comprises the following steps:
[0023] (1) The raw material slices enter the screw extruder with electric heating function through the hopper, so that the slices are molten;
[0024] (2) The above-mentioned molten material is quantitatively pressed into the spinning assembly through a metering pump and sprayed out from the spinneret to form a tow in the spinning box;
[0025] (3) The tow is cooled by side blowing through the spinning box, and further cooled through the tunnel;
[0026] (4) oiling the cooled tow;
[0027] (5) Through intertwining, the oil content of the tow is more uniform and the degree of cohesion is higher;
[0028] (6) The drawing and setting of the tow through the hot roller;
[0029] (7) winding forming;
[0030] It is characterized in that it also includes the step of ...
Embodiment 2
[0035] In the production method of the oxygen bar fiber with anion function described in this embodiment, the anion masterbatch is made of hexacyclite nanoparticles, the raw material slices are polyhydantam slices, and the others are the same as in Example 1.
[0036] The oxygen bar fiber with negative ion function obtained in this embodiment has an emission concentration of about 6000-7000 negative ions per cubic centimeter.
