ラメントからの脱落がなく、また長期間の使用に耐える
糸を作ることができる。According to the present invention, since ceramic powder is mixed inside the spun filament, the ceramic powder does not fall off from the filament, and a thread that can be used for a long period of time can be produced.
以下本発明の一実施例を図面に付き説明する。 An embodiment of the present invention will be described below with reference to the drawings.

状素材が形成される。The drawing is a block diagram showing the steps of the method for manufacturing ceramic thread according to the present invention, in which a polyethylene terephthalate polymer powder is selected as the base material of the ceramic thread, and a ceramic powder such as cordierite is added to the polymer powder. Alternatively, metal oxide powder such as alumina is mixed to form a pellet-like material.

糸として巻取られる。The powder and granular material is set to have a size of about 0.61 to 20 microns in consideration of the influence on the spinning nozzle and the far-infrared radiation effect.The pellet-like material is made of polyethylene by a melting device (not shown). Temperatures above 260°C to 265°C, which is the melting point of terephthalate, e.g. 28°C
It is heated to 0°C. Further, the molten pellet-like material is maintained at a melt viscosity of 2000 to 5000 P, which is suitable for spinning. Such a pellet-like material is extruded from a spinneret, cooled and solidified, and then wound onto a bobbin as thread.

という効果を奏する。As described above, according to the present invention, ceramic thread is produced in which ceramic or metal oxide powder is mixed into the polymer, so the powder does not fall off from the polymer, and the thread does not fall off. Flexibility does not decrease, so the properties of the product are improved compared to those coated with ceramics, and the period of use is also longer than that of conventional products.
