Embodiment 1
[0023] a) material preparation
[0024] 70g of ferric oxide, 22g of barium oxide, 2g of strontium oxide, 2g of silicon dioxide, 2g of calcium oxide, and 2g of manganese oxide.
[0025] b) Production of multi-element mixed superfine powder
[0026] After mixing evenly according to the ratio of step a), the mixture is ground into a multi-element mixed ultrafine powder with a particle size of ≤0.5 micron by a jet mill.
Embodiment 2
[0028] Use polyester as the base material, slice the polyester, and slice the thickness ;
[0029] Take by weighing polyester slice 1200g, take by weighing the multi-element mixed superfine powder 1000g that embodiment 1 obtains;
[0030] Add 30g of silane series r-methacryloyltrimethoxysilane into 80ml of ethanol to fully dissolve them to form a polymer spinning aid;
[0031] After mixing polyester slices and multi-element mixed ultrafine powder, add polymer spinning aid, put it in a twin-screw mixer to melt, and fully stir for 20-40 minutes, the melting temperature is 260-286 °C;
[0032] The molten and fully stirred mixture is granulated by a twin-screw granulator to form far-infrared magnetic masterbatches.
Embodiment 3
[0034] Heat the far-infrared magnetic masterbatch to 260-286°C to form a melt. According to the traditional process, the melt is passed through the screw extruder, and the metering pump is pressed out of the spinneret hole to form a thin stream and inject it into the air. , become thin strips after condensation; the thin strips are cooled and solidified, curled and drawn to form far-infrared magnetic fibers.

Abstract
The invention relates to a far-infrared magnetic fiber and a production method thereof. It is characterized in that the base material used is polyester, polypropylene or nylon, and the multi-element mixed superfine powder contains: ferric oxide, barium oxide, strontium oxide, silicon dioxide, calcium oxide, and manganese oxide. The production method is as follows: the raw materials are made into multi-element mixed superfine powder; the base material is sliced and mixed with multi-element superfine powder for stirring, and polymer spinning aid is added, melted and fully stirred; the melted and fully stirred mixture Granulate through a twin-screw granulator to form far-infrared magnetic masterbatch; the masterbatch containing far-infrared magnetism is heated to form a melt, and the melt is passed through a screw extruder, and the metering pump is used to press out the spinneret hole, and after condensation, it becomes a thin strip ; After cooling and solidification, curling and drawing, far-infrared magnetic fibers are formed.
Description
technical field [0001] The invention relates to a far-infrared fiber and a production method thereof, in particular to a far-infrared magnetic fiber and a production method thereof. Background technique [0002] With the development of science and technology, people pay more and more attention to the effects of various trace elements on the human body. At present, nanotechnology is becoming more and more mature, and functional fibers made by adding composite inorganic nanopowders rich in trace elements to traditional chemical fibers have been launched one after another. Among them, far-infrared products made by adding far-infrared ceramic powder to chemical fibers have a significant health function of improving human microcirculation, which has been verified by inspection and recognized by consumers. [0003] The influence of magnetism on the meridians of the human body has been introduced in "Compendium of Materia Medica". Now magnetic therapy has become a method of human ...
