Description
본 발명은 복합보온성 폴리에스테르 섬유에 관한 것으로 섬유자체적으로 원적외선이 방사되고, 신체에서 발산되는 체열를 반사하여 보온성이 우수한 복합보온성 폴리에스테르 섬유에 관한 것이다.The present invention relates to a composite heat-resistant polyester fiber, and more particularly, to a composite heat-resistant polyester fiber having excellent heat retention by reflecting far-infrared rays of the fibers themselves and radiating body heat emitted from the body.
섬유제품의 보온성에 관한 관심과 기술개발을 위한 연구는 섬유산업의 초기부터 이루어져왔다.Interest in the warmth of textile products and research for technology development have been made since the early days of the textile industry.
섬유제품의 보온의 개념은 인체에서 방출되는 열을 외부로 손실되지 않게 하는 단열에 의한 소극적 보온효과에서 적외선 반사소재를 사용하는 방법, 인체 방사 에너지를 흡수하는 소재를 사용하는 방법 등 축열, 발열 등의 적극적 보온효과로 점차 연구영역이 넓어지고 있다.The concept of thermal insulation of a textile product is a method of using infrared reflective material in a passive warming effect by heat insulation which does not lose the heat radiated from the human body to the outside, a method of using a material absorbing human radiant energy, The research area is gradually widening due to the active warming effect.
소극적 보호효과는 공기층에 의한 단열보온방식은 피복을 구성하는 직물의 두께를 증가시키는 이유가 되어 활동성이 낮아지는 원인이 되며, 기타 소재를 이용하는 방식은 피복의 세탁성이나 내구성을 저하시키는 요소가 되어 범용적으로 사용하기 어려운 단점이 있다. The passive protection effect is caused by the increase of the thickness of the fabric constituting the covering layer due to the air layer, which causes the activity to be lowered, and the method using other materials is a factor that deteriorates the washing property and durability of the covering There is a disadvantage that it is difficult to use it universally.
대한민국 실용신안공고 제200227811호에서는 방적사 또는 멀티필라멘트사인 경사와위사가 서로 교차하여 제직된 원단에 있어서, 폴리아미드 섬유 상에 은이 도금되어 있는 은 도금사가 경사방향 또는 위사 양방향에 일정간격으로 배열되어 있는 것을 특징으로 하는 다기성 원단이 제안되었다. 상기 원단은 은 도금사가 경사 또는 위사방향을 일정하게 배열되어 있어 제전효과 및 단열이나 보온효과가 우수한 특성이 있다고 하지만 직물에 일정 간격으로 배치된 은 도금사의 존재로 보온효과를 기대하기는 상기 은도금사와 함께 직조되는 더 많은 올 수의 열전도도에 차이가 없는 일반사로 인해 단열성이나 보온성을 발현하기가 어렵다. 더욱이 은 도금사가 배치된 부분 외에 대부분이 열전도도가 낮은 섬유로 구성된다는 점은 동일층의 직물에서 일부분의 열전도도 차이로 인해 단열성을 구현되지 않아 효과가 미미한 문제점이 있었다.Korean Utility Model Provisional Publication No. 200227811 discloses a fabric obtained by weaving yarn yarns and multifilament yarns intersecting weft yarns and weft yarns in such a manner that silver plated yarns plated on polyamide fibers are arranged at regular intervals in both oblique and weft directions And the like. Although the silver plated yarn has the characteristics of excellent antistatic effect and thermal insulation or thermal insulation effect because the silver plating yarns are arranged in the warp or weft direction constantly, in order to expect a warming effect in the presence of the silver plated yarn arranged at regular intervals in the fabric, It is difficult to exhibit heat insulation and warmth due to the general yarn having no difference in the thermal conductivity of more wool which is woven together. In addition, the fact that most of the fabric is made of fibers having low thermal conductivity in addition to the portion where the silver plating yarns are disposed has a problem in that the effect is insufficient because the heat insulating property is not realized due to a difference in thermal conductivity of a part of the fabric of the same layer.
적극적 보온효과는 축열 소재의 활용한 보온, 세라믹 등이 소재를 통한 원적외선 방출을 통한 보온, 열을 직접적으로 발생시키는 소재나 구성을 통한 보온 등이 있으며, 국제공개공보 WO2002/34988에서는 전원으로부터 열을 발생시키기 위한 전도성 사로 제조된 직물로서 일 이상의 비전도성사와 일 이상의 양의 온도계수(PTC)가열사를 포함하고 상기 비전도성사 및 PTC 가열사가 조합되어 가열 직물을 형성하는 구조가 제안되었다. 상기 발명은 별도의 전원을 발생시키는 구조가 필요하며 피복적합성이 저하되는 등 문제가 있다.The active warming effect can be achieved by the heat insulation using the heat accumulating material, the warming through the far-infrared ray emission through the material such as the ceramic, and the warming through the material or the structure directly generating heat. In WO2002 / 34988, There has been proposed a structure in which one or more nonconductive sheets and one or more positive temperature coefficient (PTC) heating yarns are combined as a fabric made from conductive yarn to form a heating fabric, and the nonconductive sheet and the PTC heating yarn are combined to form a heating fabric. The above-described invention requires a structure for generating a separate power source, and there is a problem that the suitability for covering is lowered.

도 1은 본 발명에 따른 복합보온성 폴리에스테르 섬유의 일실시예의 단면을 나타낸 도면이고, 도 2는 본 발명에 따른 복합보온성 폴리에스테르 섬유의 또다른 실시예의 단면을 나타낸 도면이다.Fig. 1 is a cross-sectional view of one embodiment of the composite heat-resistant polyester fiber according to the present invention, and Fig. 2 is a cross-sectional view of another embodiment of the composite heat-resistant polyester fiber according to the present invention.
본 발명은 원적외선을 방출하는 텅스텐 카바이드(WC) 및 체열을 반사할 수 있는 산화알루미늄((Al2O3)을 폴리에스테르 섬유에 함유시켜 보온성을 효과적으로 향상시킬 수 있는 복합보온성 폴리에스테르 섬유에 관한 것이다.The present invention relates to a composite thermal insulation polyester by incorporating the aluminum oxide to reflect the tungsten carbide (WC) and body temperature, which emits far-infrared ((Al 2 O 3) to a polyester fiber which can effectively improve the thermal insulation fibers .
상기 텅스텐 카바이드, 산화알루미늄은 원적외선을 방출하여 체온을 상승을 통한 보온성을 높이는 작용을 하며, 상기 산화알루미늄은 신체에서 발생되는 체열을 반사시켜 다시 신체로 돌려보내는 작용으로 복합적인 기능으로 폴리에스테르 섬유의 보온성을 높이게 된다.The tungsten carbide and aluminum oxide emit far-infrared rays to increase the warmth by raising the body temperature. The aluminum oxide reflects the body heat generated from the body and returns it to the body. As a result, The warmth is enhanced.
상기 텅스텐 카바이드(WC), 산화알루미늄의 함량이 너무 적으며 보온성의 상승효과가 크지 않으며, 상기 텅스텐 카바이드(WC), 산화알루미늄의 함량이 너무 많으면 섬유 제조시 사절현상 등이 발생하여 공정성이 저하될 수 있으므로 함유되되, 상기 텅스텐 카바이드(WC), 산화알루미늄는 각각 폴리에스테르 섬유 중량의 0.1~2중량%가 함유되는 것을 특징으로 하는 복합보온성 폴리에스테르 섬유를 제공한다.The content of the tungsten carbide (WC) and the aluminum oxide is too small and the synergistic effect of warming property is not significant. If the content of tungsten carbide (WC) and aluminum oxide is too large, , Wherein the tungsten carbide (WC) and the aluminum oxide each contain 0.1 to 2% by weight of the polyester fiber.
또한, 상기 텅스텐 카바이드와 산화알루미늄의 크기가 너무 크면 방사공정에서 기계장치의 마모율을 높일 수 있으므로, 상기 텅스텐 카바이드와 산화알루미늄의 크기는 0.05~1㎛인 것이 바람직할 것이다.If the sizes of the tungsten carbide and aluminum oxide are too large, the wear rate of the mechanical device in the spinning process can be increased. Therefore, the size of the tungsten carbide and the aluminum oxide is preferably 0.05 to 1 μm.
상기와 같이 텅스텐 카바이드와 산화알루미늄을 함유하는 본 발명의 폴리에스테르 섬유는 도 1에서와 같이 텅스텐 카바이드(100)와 산화알루미늄(200)이 섬유 내부에 단순히 함유된 상태에서도 보온 효과가 우수하지만, 본 발명의 복합보온성 폴리에스테르 섬유의 보온효과를 더욱 높이기 위해 도 2에서와 같이 본 발명의 폴리에스테르 섬유를 시스부와 코어부를 갖는 시스-코어형 복합섬유로 형성하는 것이 바람직할 것이다.As described above, the polyester fiber of the present invention containing tungsten carbide and aluminum oxide as described above is excellent in thermal insulation effect even when tungsten carbide (100) and aluminum oxide (200) are simply contained in the fiber, In order to further enhance the warming effect of the composite heat-resistant polyester fiber of the present invention, it is preferable to form the polyester fiber of the present invention with the sheath-core type composite fiber having the sheath portion and the core portion as shown in Fig.
상기 시스-코어형 복합섬유로 형성될 경우에는 코어부에는 텅스텐 카바이드(100)를 함유시키고, 시스부에는 산화알루미늄(200)을 함유시켜 본 발명의 복합보온성 폴리에스테르 섬유를 형성할 수 있을 것이다.In the case of the sheath-core type composite fiber, the core portion may contain tungsten carbide (100) and the sheath portion may contain aluminum oxide (200) to form the composite heat-resistant polyester fiber of the present invention.
상기 시스부에 함유되는 산화알루미늄은 도 1의 폴리에스테르 섬유에 비해 섬유외곽에 산화알루미늄의 함량이 높아지게 되어 체열을 반사하는 기능이 더 상승하게 되어 보온성을 더욱 향상시킬 수 있다.The aluminum oxide contained in the sheath portion has a higher content of aluminum oxide on the outer side of the fiber than in the polyester fiber of Fig. 1, so that the function of reflecting body heat further increases, thereby further improving warmth.
상기 본 발명의 복합보온성 폴리에스테르 섬유는 사용용도 및 목적에 따라 다양한 이형단면 형태 및 또다른 기능성 물질을 함유시킬 수 있을 것이다.The composite heat-resistant polyester fiber of the present invention may contain various modified cross-sectional shapes and other functional materials depending on the intended use and purpose.
상기와 같이 본 발명에 따른 복합보온성 폴리에스테르 섬유를 함유하는 원단은 복합보온성 폴리에스테르 섬유의 원적외선 방사기능, 체열을 반사하는 기능을 통해 보온성을 높일 수 있어 의류용에 적합할 것이다.As described above, the fabric containing the composite heat-resistant polyester fiber according to the present invention can improve the warmth through the function of reflecting the far-infrared radiation function and the body heat of the composite heat-resistant polyester fiber, and thus it is suitable for clothing.
이하 본 발명에 따른 복합보온성 폴리에스테르 섬유를 제조하기 위한 방법의 실시예를 나타내지만, 본 발명이 실시예로 한정되는 것은 아니다.Hereinafter, examples of the method for producing the composite heat-resistant polyester fiber according to the present invention are shown, but the present invention is not limited to the examples.
