And this kind of existing anion fiber is because material selection, production process are unreasonable, and anion emission concentration is less (usually only has 2500-3500 per cubic centimeter), and what have is the anion product in name even more
[0005] Therefore, the existing negative ion fibers cannot effectively meet people's needs, and it is necessary to improve the production process

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 ...

Abstract
The invention discloses a production method of oxygen-bar fiber with negative ion function. The production method comprises the following steps: (1) entering raw material slices into a screw extruder with electrical heating function through a bunker so that the slices are in a fusion state; and (2) quantitatively pressing the fused material into a spinning component through a metering pump and spraying the fused material out through a spinneret plate to form tows in a spinning box body, and the like. The production method is characterized by comprising the step of adding negative ion master batch, wherein the negative ion master batch is prepared from opal nano microparticles or hexacyclic ring stone nano microparticles. In the production method of the oxygen-bar fiber with negative ion function, special selected materials and preparation process are adopted, the negative ion emission concentration of the produced oxygen-bar fiber with negative ion function is about 5500-7000 negative ions per cubic centimeter, and is nearly twice as high as that of the existing negative ion fiber, thus the oxygen-bar fiber with negative ion function is a negative ion product in true sense.
Description
technical field [0001] The invention relates to a production method of chemical fiber filaments, in particular to a production method of oxygen bar fibers with anion function. Background technique [0002] With the development of science, the current synthetic fiber technology has also made great progress. Synthetic fibers are widely used in industrial production such as textiles and clothing due to their good shaping effect, high strength, good elasticity, strong wear resistance and corrosion resistance. middle. In the production process of synthetic fibers, the melt is sprayed from the spinneret holes on the spinneret to form primary fibers, which are then processed into finished synthetic fibers through subsequent processes. [0003] Negative ion fiber (English for negative ion is ANION, that is, negatively charged oxygen molecules) is a fiber with negative ion release function. The negative ions released by the fiber have obvious effects on improving air quality and env...
