보온성 섬유의 제조방법Manufacturing method of thermal insulation fiber

본 발명은 보온성 섬유의 제조방법에 관한 것으로, 좀 더 상세하게는 태양광하에서 축열하는 기능을 갖고, 정전기 발생이 없는 것을 특징으로 하는 도전 보온성 섬유의 제조방법에 관한 것이다.The present invention relates to a method for producing a thermally insulating fiber, and more particularly, to a method for manufacturing a conductive thermally insulating fiber, which has a function of heat storage under sunlight and is free of static electricity.

최근에는 새로운 보온 소재로 원적외선을 이용한 것들이 각광을 받고 있다. 예를 들어 일본특개소 제 64-41764호, 동 63-92720, 동 63-182444호, 동 63-2038784호, 일본특개평 제 1-132816호등에는 원적외선 방사율이 높은 물질을 사(絲)내에 혼입시키거나 직물에 코팅함으로써, 태양광을 흡수한 후 원적외선으로 변환시켜 신체에 재방사 되도록하여 축열보온효과와 생체리듬의 활성화효과를 발휘하도록한 보온소재의 제조방법이 공지되어 있다.In recent years, the use of far infrared rays as a new insulating material has been in the spotlight. For example, Japanese Patent Application Laid-Open Nos. 64-41764, 63-92720, 63-182444, 63-3838784, and 1-132816, Japanese Laid-Open Patent Publications, contain substances with high far-infrared emissivity. By incorporating or coating a fabric, there is known a method of manufacturing a thermal insulation material that absorbs sunlight and converts it into far-infrared rays so as to be radiated back to the body to exert an effect of regenerative thermal insulation and activation of biological rhythm.

그러나 상기 발명들에서 원적외선 방사율이 높은 세라믹물질인 산화알루미늄(Al2O3), 산화실리카(SiO2), 산화크롬(Cr2O3), 석회석(CaCO3), 첨정석(MgO·Al2O3), 산화칼슘(CaO2), 산화바륨(BaO), 실리카카바이드(SiC), 티타늄카바이드(TiC), 산화제르코늄(ZrO2), 제르코늄카바이드(ZrC) 중 1종 또는 2종 이상의 혼합물을 사(絲)내에 혼입하는 경우, 세라믹 성분이 사(絲)내에 적어도 0.1wt% 이상 함유되어야 목적하는 보온성을 얻을 수 있으며, 세라믹물질의 첨가량이 10wt% 이상이면 방사작업성이 급격히 저하되는 문제가 있다고 보고되어 있다.However, in the above inventions, aluminum oxide (Al 2 O 3 ), silica oxide (SiO 2 ), chromium oxide (Cr 2 O 3 ), limestone (CaCO 3 ), spinel (MgO · Al 2 ), which are ceramic materials having high far-infrared emissivity O 3 ), calcium oxide (CaO 2 ), barium oxide (BaO), silica carbide (SiC), titanium carbide (TiC), zirconium oxide (ZrO 2 ), zirconium carbide (ZrC) or one or more When the mixture is incorporated in the yarn, the desired thermal insulation must be contained at least 0.1 wt% or more in the yarn, and if the addition amount of the ceramic material is 10 wt% or more, the spinning workability is rapidly decreased. There is a problem reported.

또한 보온성 섬유를 제조함에 있어서, 가장 큰 영향을 주는 사(絲)내 세라믹물질의 함량, 세라믹물질의 순도 및 평균입경의 문제점을 해결하였다고 하더라도 용도에 따라 정전기 문제가 발생되어 인체에 쇼크를 일으키거나 화재 및 폭발사고를 유발할 우려가 있다.In addition, even if the problem of the content of the ceramic material, the purity and average particle size of the ceramic material that has the greatest influence in the manufacture of the thermal insulation fiber, electrostatic problems are generated depending on the use, causing shock to the human body or It may cause fire and explosion accident.

본 발명은 상술한 문제점을 해결하기 위한 것으로, 사(絲)내에 세라믹 성분의 첨가로 보온성이 향상되고, 도전성 입자의 첨가로 정전기성이 향상된 섬유를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a fiber in which heat insulation is improved by adding a ceramic component in the yarn, and electrostatic properties are improved by addition of conductive particles.

즉, 본 발명은 세라믹 충전물을 사(絲)내에 혼입하여 보온성 섬유를 제조함에 있어서, 도전성 물질을 카본, 니켈, 황화구리, 금속산화물, 저융점금속 등으로 구성되는 그룹으로 부터 선택되는 1종 이상을 첨가하여 정전기성을 향상시키는 것을 특징으로 하는 보온성 섬유의 제조방법에 관한 것이다.That is, in the present invention, at least one member selected from the group consisting of carbon, nickel, copper sulfide, metal oxides, low melting point metals, etc., in the preparation of thermally insulating fibers by incorporating a ceramic filler into the yarns It relates to a method for producing a thermally insulating fiber, characterized in that by adding to improve the electrostatic properties.

본 발명에 사용되는 상기 도전성 물질의 유용한 첨가량은 보온성 섬유 대비 1∼15중량%, 보다 바람직하게는 5-10중량%이다. 상기 첨가제의 첨가량이 보온성 섬유 대비 1중량% 미만인 경우에는 본 발명의 목적하는 효과인 우수한 정전기성을 기대하기 어렵고, 15중량%를 초과하면 방사성 불량 및 최종 원사의 기계적 물성의 저하가 초래되어 제조 원가의 상승에 따라 상업적 가치를 상실하게된다.Useful amounts of the conductive material used in the present invention are 1 to 15% by weight, more preferably 5 to 10% by weight relative to the insulating fiber. When the amount of the additive is less than 1% by weight compared to the heat-insulating fiber, it is difficult to expect the excellent electrostatic property, which is the desired effect of the present invention, and when the amount is more than 15% by weight, the radioactive defect and the deterioration of the mechanical properties of the final yarn are caused. As you rise, you will lose your commercial value.

본 발명에서 세라믹 충전제의 첨가량은 보온성 섬유 대비 0.3중량%∼10중량%이다. 상기 세라믹 충전물의 첨가량이 원사 대비 0.3중량% 미만일 경우에는 본 발명이 목적하는 보온성을 얻을 수 없으며, 10중량%를 초과하면 섬유의 물성저하 및 사절현상이 발생하므로, 본 발명에서 세라믹 충전물의 첨가량은 상기 범위인 것이 필수적이다.In the present invention, the amount of the ceramic filler added is 0.3% by weight to 10% by weight relative to the insulating fiber. When the amount of the ceramic filler added is less than 0.3% by weight of the yarn, the present invention cannot obtain the desired thermal insulation, and when the amount of the ceramic filler exceeds 10% by weight, the physical properties of the fiber and the trimming phenomenon occur. It is essential that the above range.

본 발명에서 사용되는 세라믹 충전제로는 주기율표 4족에 속하는 세라믹 중에서 1종 또는 2종 이상이 사용 가능하며, 특별히 제르코늄카바이드가 도전성물질과 혼합 방사시 양호한 성능을 가지므로 가장 바람직하다.As the ceramic filler used in the present invention, one or two or more kinds of ceramics belonging to the Group 4 of the periodic table may be used, and in particular, zirconium carbide is most preferable because it has good performance when mixed spinning with a conductive material.
