Embodiment 1

[0029] Get 32 ​​parts of polyethylene terephthalate after drying (weight, the same below), 1 part of silver chloride powder, 0.5 part of sodium pentachlorophenolate, N-(trichloromethylthio) phthalate 0.5 parts of imide, 65 parts of strontium ferrite magnetic powder, 1 part of isopropyl triisostearyl titanate, after thorough mixing, twin-screw extrusion at 265 ° C, granulation, to produce spinning Use the mixed material; after fully drying the obtained mixed material, spin the coiled yarn with a melt spinning machine; then stretch the coiled yarn 3 times at a temperature of 95°C to obtain the finished yarn; finally, the finished yarn is Magnetizing treatment, magnetizing at a magnetic field strength of 12,000 Gauss for 2 minutes, the magnetic fibers can be obtained. It is determined that the antibacterial rate of the obtained fiber is 63%, and the average value of the magnetic field strength of the fiber is 46 gauss.

Embodiment 2

[0031]Get 82.8 parts of polypropylene with a melt index of 50, 0.5 part of silver oxide powder, 0.5 part of pentachlorophenol, 16 parts of strontium ferrite magnetic powder, 0.2 part of isopropyl tris(dodecylbenzenesulfonyl) titanate, After thorough mixing, extrude through twin-screw at 195°C and granulate. The mixture for spinning is produced; after the mixture is fully dried, the coiled yarn is spun with a melt spinning machine; the coiled yarn is stretched 4 times at a temperature of 65°C to obtain a finished yarn; and the finished product The silk is magnetized under a magnetic field strength of 12000 gauss for 0.1 minute to obtain the magnetic fiber. It is determined that the antibacterial rate of the obtained fiber is 35%, and the average value of the magnetic field strength of the fiber is 2 gauss.

Embodiment 3

[0033] Take 67.9 parts of polyethylene with a melt index of 35, 0.1 part of copper oxide powder, 0.2 part of zinc oxide powder, 0.5 part of silver nitrate powder, 0.8 part of salicylanilide, 20 parts of barium ferrite magnetic powder, neodymium iron 10 parts of boron magnetic powder, 0.5 parts of isopropyl tris(dodecylbenzenesulfonyl) titanate, after thorough mixing, twin-screw extrusion at 170°C, and granulation. The mixed material for spinning is produced; then spinning and post-treatment are carried out according to Example 2 to obtain the magnetic fibers. It is determined that the antibacterial rate of the obtained fiber is 52%, and the average value of the magnetic field strength of the fiber is 18 gauss.

Abstract

The present invention relates to magnetic fiber and its making process. The magnetic fiber is mixture including polymer 30-82.8 wt%, magnetic powder 16-65 wt%, anti-bacterial agent 1-4 wt% and modifier 0.2-1 wt%. The magnetic powder has average granularity of 0.5-1.5 microns; and the anti-bacterial agent includes inorganic anti-bacterial agent and organic anti-bacterial agent with average granularity of 0.05-0.4 microns. The making process of the magnetic fiber includes: preparing spinning material through mixing, extruding at 180-270 deg.c with double-screw extruder and pelletizing; producing fiber through spinning the mixture material and extending in 2-4 times at 65-95 deg.c; and magnetizing the composite fiber in magnetic field of 12000 gauss for 0.1-2 min to obtain the magnetic fiber. The fiber of the present invention has magnetic health care and antibiotic performance.

Description

technical field [0001] The invention relates to a functional chemical fiber and its manufacturing method technology, in particular to a magnetic fiber and its manufacturing method technology. Its IPC main classification number is proposed to be Int.C17 D01F 10 / 00. Background technique [0002] Magnetic fiber is a functional fiber that has a certain health care effect on the human body. There are also many patent literature reports on magnetic fibers at home and abroad. For example, Japanese Patent Hei 3-130413 introduces a method for manufacturing magnetic fibers by the skin-core method. The skin layer is polymer, the core layer is a mixture of polymer and magnetic powder, and the content of magnetic powder accounts for 5-70% of the fiber core material. Since the sheath of the fiber is made of pure polymer, the sheath material has no antibacterial properties, and the fiber also only has a single magnetic function. Chinese patent CN1252460 discloses a kind of magnetic heal...
