본 발명은 광발열 폴리에스테르 복합가연사의 제조방법에 관한 것으로서 효과사로 광발열 폴리에틸렌테레프탈레이트 필라멘트를, 심사로 폴리프로필렌 미연신 필라멘트를 사용하여 가연한 후 인터레이스한 것이다.TECHNICAL FIELD The present invention relates to a process for producing a light-generating polyester multifunctional continuous yarn, and more particularly, to a process for producing a light-generating polyester multifunctional polyester yarn by thermally fusing a light-generating polyethylene terephthalate filament with a polypropylene unstretched filament.

최근 지구온난화로 인한 기상이변이 속출하는 가운데, 전 세계적으로 친환경 제품개발에 대한 노력이 증가하고 있다. 정부에서는 온난화현상으로 인한 기후변화를 대처하기 위하여 이산화탄소의 발생을 저감시키고, 에너지를 절감할 수 있는 새로운 신소재의 개발을 요구하고 있는데, 이에 즈음하여 국내 화섬메이커들이 원사를 이용한 방법과 후가공 기술을 이용한 기술을 접목하여 신개념의 광발열 소재의 제품을 개발하고 있다.Recently, global warming has led to an increase in efforts to develop eco-friendly products worldwide. In order to cope with climate change caused by global warming, the government is demanding the development of new materials that can reduce the generation of carbon dioxide and save energy. At this time, domestic synthetic fiber makers use yarns and post- Technology to develop a new concept of light-emitting material.

현재 국내에 출시되고 있는 다양한 형태의 광발열 섬유의 제품들은 탄화지르코늄과 산화지르코늄에 의해서 태양광의 95%인 적외선, 가시광선 이상의 단파정 영역에서 흡수율이 높은 물질로 태양광을 열에너지로 전환하여 축열하는 원리를 이용하여 광의 95%를 흡수하여 열에너지로 변환하여 의복으로 반사하여 의복 내에 열에너지가 축열되는 원리를 이용한 섬유제품을 개발하고 있다.Currently, various types of optical heating fiber products that are currently being launched in Korea are made of zirconium carbide and zirconium oxide, which absorbs 95% of the sunlight and absorbs the infrared light in a short wave region or more. Using the principle, 95% of the light is absorbed and converted into thermal energy, reflected by clothing, and the thermal energy is stored in the clothes.

이러한 광발열 섬유 제품은 태양의 열에너지를 축적시킨 후 이를 인체로 재방사하여 온도의 상승을 가져오며 금속화합물 중 태양광을 적극적으로 흡수시키는 물질인 탄화지르코늄과 산화지르코늄을 이용해 광발열 섬유제품 형태를 말하는 것으로서 탄화지르코늄과 산화지르코늄은 섬유의 코어 부분에 혼입하여 복합섬유로 만들거나, 코팅 또는 라미네이트 소재의 수지피막에 분산ㅇ혼입하는 방법으로 섬유를 개발하고 있다.Such heat-generating fiber products accumulate heat energy of the sun and then radiate it to the human body to raise the temperature. Using zirconium carbide and zirconium oxide, which actively absorb sunlight among metal compounds, As described above, zirconium carbide and zirconium oxide are mixed with a core portion of a fiber to form a composite fiber, or a fiber is mixed and dispersed in a coating film of a coating or a laminate.

이러한 섬유들은 발열영역이 적외선(IR) 파장 Zone에 일어나고, 직물이나 편물제조시 세탁 및 마찰 등에 의해 내구성이 급격히 저하되는 경향이 있으며, 섬유자체의 신도가 부족하여 다양한 제품으로의 전개가 어려운 실정이었다. These fibers tend to have a heat generation region in an infrared (IR) wavelength zone, a durability tends to decrease sharply due to washing and rubbing in fabrics or knitted fabrics, and the elongation of the fibers themselves is insufficient, .

상기 효과사와 심사를 공기압 1.8~2.9kg/㎠로 인터레이스한 후 제5피드롤러를 거쳐 오일처리하고 사속 400 ~ 450m/분으로 권취하는 것을 특징으로 하는 광발열 폴리에스테르 복합가연사의 제조방법이 제공된다.Wherein the effect yarn and the yarn are interlaced at an air pressure of 1.8 to 2.9 kg / cm < 2 >, followed by oiling through a fifth feed roller and winding at a speed of 400 to 450 m / min. .

이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명의 광발열 폴리에스테르 복합가연사는 효과사로 광발열 폴리에틸렌테레프탈레이트 필라멘트를, 심사로 폴리프로필렌 미연신 필라멘트를 사용하여 가연한 후 인터레이스하여 제조된다.The heat-generating polyester composite false-twist yarn of the present invention is produced by subjecting a light-generating polyethylene terephthalate filament to an effect by twisting the filament by using a polypropylene unstretched filament and then interlacing it.

도 1에서와 같이 효과사(1)로 광발열 폴리에틸렌테레프탈레이트 필라멘트를 제1피드롤러(3)를 통과시켜 제3피드롤러(4)로 공급하고, 심사로 폴리프로필렌 미연신 필라멘트(2)를 제2피드롤러(5)를 통과시켜 제4피드롤러(6)로 공급하고, 상기 효과사 및 심사를 히터(7)에서 열처리온도 160∼180℃로 열처리한 후, 가연기구(8)에 의해 TPM 2000~2500으로 가연을 한다. 1, the light generating polyethylene terephthalate filament was fed through the first feed roller 3 to the third feed roller 4, and the non-drawn filament 2 was fed to the third feed roller 4, Is fed through the second feed roller 5 to the fourth feed roller 6 and the effect yarn and the yarn are thermally treated at a heat treatment temperature of 160 to 180 ° C in the heater 7, TPM 2000 ~ 2500 will be flammable.

상기 효과사인 광발열 폴리에틸렌테레프탈레이트 필라멘트는 쉬쓰부가 일반 폴리에틸렌테레프탈레이트이고, 코어부가 탄화지르코늄 또는 탄화실리콘 미세입자가 1~2중량% 함유된 폴리에틸렌테레프탈레이트로 이루어진 광발열 폴리에틸렌테레프탈레이트 필라멘트인 것을 사용하는 것이 태양광을 자체적으로 흡수하여 열에너지로 변환, 원적외선 형태로 방사하여 복합가연사의 광발열효과를 발현하는데 바람직하며, 심사로 폴리프로필렌 미연신 필라멘트를 사용하는 것이 복합가연사의 신축성발현에 바람직하다.The heat-generating polyethylene terephthalate filament as the effective sign is a light-generating polyethylene terephthalate filament composed of a polyethylene terephthalate as a sheath portion and polyethylene terephthalate as a core portion containing zirconium carbide or silicon carbide fine particles in an amount of 1 to 2 wt% Is preferable for self-absorbing sunlight to convert it into thermal energy and spin it in a far-infrared ray form to manifest the light exothermic effect of the composite yarn twist yarn, and to use the polypropylene unoriented filament for the examination is preferable for manifesting the elasticity of the composite yarn twist yarn.

상기 효과사의 제1피드롤러와 제3피드롤러사이의 오버피드율은 1.05~1.10이며, 상기 심사의 제2피드롤러와 제4피드롤러사이의 오버피드율은 1.02~1.05인 것이 바람직한데, 상기 효과사의 제1피드롤러와 제3피드롤러사이의 오버피드율이 1.05미만인 경우에는 절사 문제점이 발생하며, 1.10초과시에는 장력불균일한 문제점이 발생한다. 상기 심사의 제2피드롤러와 제4피드롤러사이의 오버피드율은 1.02미만인 경우에는 신축성이 저하되는 문제점이 발생하며, 1.05초과시에는 장력불균일한 문제점이 발생한다.The overfeed ratio between the first feed roller and the third feed roller is 1.05 to 1.10 and the overfeed ratio between the second feed roller and the fourth feed roller is 1.02 to 1.05. If the overfeed rate between the first feed roller and the third feed roller of the effect yarn is less than 1.05, a cutting problem occurs. If the over feed rate is greater than 1.10, a problem of nonuniform tension occurs. If the overfeeding ratio between the second feed roller and the fourth feed roller is less than 1.02, the stretchability is lowered. If the overfeed rate is greater than 1.05, the tension is uneven.

상기 광발열 폴리에틸렌테레프탈레이트 필라멘트의 결정화 온도를 감안할 때 본 발명의 상기 가연 작업시 히터(7)에서의 열처리 온도는 160~180℃로 하는 것이 복합사 조건에 바람직하다. 온도가 160℃보다 낮을 경우에는 불안정한 결정화로 인하여 크림프 고정이 안되고 신도가 높아 작업성이 저하되며, 180℃를 초과하는 경우에는 강도와 신도가 감소되며 광발열 폴리에틸렌테레프탈레이트 필라멘트의 쉬쓰부분과 코어부분의 변형이 생겨 작업성 및 원사 품질이 떨어진다.Considering the crystallization temperature of the light-generating polyethylene terephthalate filament, the heat treatment temperature in the heater 7 in the burning operation of the present invention is preferably 160 to 180 占 폚 in the composite yarn condition. When the temperature is lower than 160 ° C, the crimp is not fixed due to unstable crystallization, the workability is lowered due to high elongation, and when the temperature is higher than 180 ° C, the strength and elongation are decreased, and the sheath portion of the light generating polyethylene terephthalate filament and the core portion So that workability and yarn quality deteriorate.

본 발명에서는 상기 열처리된 효과사 및 심사를 가연기구(8)에 의해 가연을 하는데, TPM 2000~2500으로 가연을 하여 크림프를 부여한다. 본 발명에서 상기 가연기구로는 핀타입 또는 디스크타입의 가연기구를 사용할 수 있으며,보다 바람직하기로는 닙트위스터를 사용하는 것이 좋다. In the present invention, the heat-treated effect yarn and the evaluation yarn are twisted by a false twisting device 8, and the twisted yarns are twisted with TPM 2000 to 2500 to give a crimp. In the present invention, a pin-type or disk-type fusing mechanism may be used as the twisting mechanism, and more preferably, a nip twister is used.

상기 가연된 심사와 효과사는 공기압 1.8~2.9kg/㎠로 교락기구(9)에서 인터레이스한 후 제5피드롤러(10)를 거쳐 오일처리하고 사속 400 ~ 450m/분으로 권취롤러(11)로 권취하는데, 상기 인터레이스 노즐의 공기압을 1.8~2.9kg/㎠로 유지할 경우 원사의 품질 안정화를 이룰 수 있다.The twisted yarn and yarn are interlaced at an air-tightening pressure of 1.8 to 2.9 kg / cm < 2 > at the interlocking mechanism 9 and then oiled through a fifth feed roller 10 and wound around the take- If the air pressure of the interlace nozzle is maintained at 1.8 to 2.9 kg / cm 2, the quality of the yarn can be stabilized.

상기 제조방법에 의해 제조되는 폴리에스테르 복합가연사는 광발열성 및 보온성을 발현하면서도 고신축성을 부여할 수 있다.The polyester composite false wares produced by the above production method can impart high stretchability while exhibiting light heat resistance and warmth.

그러므로 본 발명의 광발열 폴리에스테르 복합가연사에 의하면 광발열성 및 보온성을 발현하는 기능성을 가지면서도 고신축성을 부여할 수 있어 동절기용 직물 또는 편물, 커텐, 담요, 양말 장갑등의 다양한 분야에 응용할수 있다.Therefore, according to the light-generating polyester multifunctional polyester yarn of the present invention, it is possible to impart high stretchability while having functionality that exhibits light heat and warmth, and can be applied to various fields such as cloths for winter season, knitted fabrics, curtains, blanket, have.
