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] Using polyester as the base material, slice the polyester into slices with a thickness of ×3mm;

[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 present invention relates to one kind of far infrared magnetic fiber and its production process, and features that the base material for producing the far infrared magnetic fiber is dacron, polypropylene or nylon with mixed superfine powder of ferric oxide, barium oxide, strontia, silica, calcium oxide and manganese oxide, accounting for 2-8 wt%. The production process of the far infrared magnetic fiber includes the steps of: preparing the mixed superfine powder, mixing the mixed superfine powder, the polymer slicing and assistant through smelting and stirring, pelletizing the mixture in a double screw pelletizing machine to form agglomerate, heating the agglomerate to form melt, extruding with a screw extruder and a metering pump through a orifice, condensating and curing, and stretching to form far infrared magnetic fiber.

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 ...
