본 발명은 고비중 및 고난연성을 갖는 코어-시스형 복합섬유에 관한 것으로서, 더욱 상세하게는 비중이 높아 드레이프성(Drape Property)이 우수함과 동시에 뛰어난 난연성을 갖고 있어서 커텐등의 인테리어 소재용 원사로 유용한 코어-시스형 복합섬유에 관한 것이다.The present invention relates to a core-sheath type composite fiber having a high specific gravity and high flame retardancy, and more particularly, a specific gravity is high, which is excellent in drape property and at the same time excellent flame retardancy. A useful core-sheath composite fiber.

폴리에스테르등과 같은 열가소성 중합체는 기계적 성질과 성형성등이 우수하여 섬유 또는 필름등의 성형재료로 널리 사용 된다.Thermoplastic polymers such as polyester have excellent mechanical properties and moldability and are widely used as molding materials for fibers or films.

그러나, 열가소성 중합체로 제조된 합성섬유는 난연성과 드레이프성이 부족하여 커텐등의 인테리어 소재용 원사로는 부적합한 문제가 있었다.However, synthetic fibers made of thermoplastic polymers have insufficient flame retardancy and drape properties, and thus are unsuitable as yarns for interior materials such as curtains.

합성섬유에 난연성을 부여하는 종래기술로서는 합성섬유로 제조된 직물을 염가공할 때 염욕내에 할로겐계 난연제를 첨가하는 후처리 가공 방법과 합성섬유의 중합시 할로겐계 난연제 또는 인계 난연제를 첨가하는 방법등이 알려져 있다Conventional techniques for imparting flame retardancy to synthetic fibers include post-treatment methods for adding halogen-based flame retardants to salt baths when fabricating fabrics made of synthetic fibers, and methods for adding halogen-based flame retardants or phosphorus-based flame retardants during polymerization of synthetic fibers. Is known

그러나, 상기의 후처리 가공방법은 세탁 및 마찰시 난연제가 탈락하여 난연성이 떨어지고 화재시 디옥신등의 유독가스가 발생하는 문제점이 있고, 중합시 난연제를 첨가하는 방법은 합성섬유를 변색시키거나 열안정성 및 내광성을 저하 시키는 문제가 있었다.However, the post-treatment processing method has a problem in that the flame retardant is dropped during washing and friction, resulting in inferior flame retardancy and toxic gases such as dioxins during fire, and the method of adding a flame retardant during polymerization discolors synthetic fibers or heat. There was a problem of lowering stability and light resistance.

한편, 미국, 유럽등에서는 연소시 디옥신이 발생되는 문제점이 있는 할로겐계 난연섬유의 사용 규제가 강화되고 있다.On the other hand, in the United States, Europe, the use of halogen-based flame retardant fiber, which has a problem that dioxin occurs during combustion is tightening.

미국특허 4033936호, 미국특허 3941752호 및 일본 특공소 59-191716, 특공소 60-101144호에서는 난연성 폴리에스테르를 제조하는 종래기술로서, 유기 인화합물의 중축합 반응이 어느 정도 진행된 후에 페닐포스폰산 지방족글리콜에스테르를 폴리에스테르의 반응성분과 함께 중축합시켜 난연성을 부여하는 방법, 아릴포스폰산 단량체를 미리 15~60wt% 함유시키고 공중합한 후 기존의 폴리에스테르와 배합하는 방법, 유기 인화합물을 BHT 반응시 첨가하고 이를 중축합하여 폴리에스테르를 제조하는 방법 및 마그네슘, 망간 등의 무기물과 유기 인화합물을 첨가하여 난연성을 부여하는 방법등을 게재하고 있으나, 공정이 복잡하고, 실직적으로 인화합물의 잔존율이 낮아 충분한 난연성을 얻기 어려운 문제점이 있다. 그뿐만 아니라 난연 폴리에스테르 제조를 위하여 사용하는 난연제가 황색을 띠게 되어 이를 폴리에스테르와 공중합하여 섬유로 사용할 경우 섬유의 색조가 황색으로 변하게 되므로 색상이 양호한 폴리에스테르를 얻기 어려운 문제점이 있다.U.S. Patent No. 4033936, U.S. Pat. Method to impart flame retardancy by polycondensation of glycol ester with reactive component of polyester, to contain 15 ~ 60wt% of arylphosphonic acid monomer in advance, copolymerize with existing polyester, and organic phosphorus compound during BHT reaction Adding a polycondensate and adding a polycondensate, and adding a inorganic and organophosphorus compounds such as magnesium and manganese to impart flame retardancy, but the process is complicated, There is a problem that it is difficult to obtain low flame retardancy. Not only that, the flame retardant used for the production of flame retardant polyester becomes yellow, and when it is used as a fiber by copolymerizing it with polyester, the color tone of the fiber is changed to yellow, which makes it difficult to obtain a good polyester.

커튼등의 인테리어 소재용 원사에는 우수한 난연성과 함께 양호한 드레이프성 발현을 위해 높은 비중이 요구 된다.Yarns for interior materials such as curtains are required to have a high specific gravity in order to express good drape property with excellent flame retardancy.

합성섬유의 비중을 높이기 위한 종래기술로서는 통상의 합성섬유내에 바륨술페이트 입자등을 첨가하는 방법이 제안된바 있으나, 상기방법은 방사 조업성이 저하되어 세섬도화가 곤란하고 균일한 염색이 곤란한 문제점이 있었다. As a conventional technique for increasing the specific gravity of synthetic fibers, a method of adding barium sulphate particles or the like into conventional synthetic fibers has been proposed. However, the above method has a problem in that the fineness of the fineness is difficult and uniform dyeing is difficult due to poor spinning operation. There was this.

본 발명은 이상에서 살펴본 종래의 문제점등을 해결할 수 있도록, 방사조업성 및 염색성의 저하 없이도 비중이 높으며, 섬유표면부의 인 함량이 높아 초기 연소에 대한 난연성이 우수하여 커튼등의 인테리어 소재용 원사로 적합한 코어-시스형 복합섬유를 제공하기 위한 것이다.The present invention has a high specific gravity even without deterioration in spinning operation and dyeing properties to solve the problems described above, and has a high phosphorus content of the fiber surface part, which is excellent in flame retardancy against initial combustion, and thus as a yarn for interior materials such as curtains. To provide a suitable core-sheath composite fiber.

본 발명은 코어-시스형 복합섬유의 코어성분내에 바륨설페이트 입자를 첨가 하여 방사조업성의 저하 없이도 비중을 높이고, 쉬스성분내의 인 함량을 코어성분내의 인 함량보다 높게하여 초기 연소에 대한 난연성이 뛰어나 인테리어 소재용 원사로 특히 유용한 코어-시스형 복합섬유를 제공하고자 한다.The present invention adds barium sulphate particles to the core component of the core-sheath composite fiber to increase specific gravity without deteriorating spinning operation, and to increase the phosphorus content in the sheath component than the phosphorus content in the core component, thereby providing excellent flame retardancy against initial combustion. To provide a particularly useful core-sheath composite fiber as a yarn for a material.

이와 같이 과제들을 달성하기 위한 본 발명의 고비중 및 고난연성 코어-시스형 복합섬유는, 코어성분(1)을 시스성분(2)이 감싸고 있는 형태인 코어(Core)-시스 (Sheath)형 복합섬유에 있어서, 상기 코어성분(1)은 난연성 인화합물을 함유하여 인 함량이 0~0.7중량%이며 바륨술포네이트 입자 함량이 5~70중량%인 열가소성 중합체이고, 상기 시스성분(2)은 난연성 인화합물을 함유하여 인 함량이 0.05~3.0중량%인 열가소성 중합체이고, 상기 시스성분(2)내 인 함량이 코어성분(1)내 인 함량 보다 2,000ppm 이상 높은 것을 특징으로 한다.The high specific gravity and high flame retardant core-sheath composite fiber of the present invention for achieving the above problems is a core-sheath composite in which the sheath component 2 is wrapped around the core component 1. In the fiber, the core component (1) is a thermoplastic polymer containing a flame retardant phosphorus compound and having a phosphorus content of 0 to 0.7% by weight and a barium sulfonate particle content of 5 to 70% by weight, and the sheath component (2) is flame retardant It is a thermoplastic polymer containing a phosphorus compound and a phosphorus content of 0.05 to 3.0% by weight, characterized in that the phosphorus content in the sheath component (2) is 2,000 ppm or more higher than the phosphorus content in the core component (1).

이하, 첨부한 도면등을 통하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

먼저 본 발명은 도1 내지 도3과 같이 코어성분(1)을 시스성분(2)이 감싸고 있는 코어-시스형(Core-Sheath Type) 단면 구조를 갖는다.First, the present invention has a core-sheath type cross-sectional structure in which the sheath component 2 surrounds the core component 1 as shown in FIGS.

도1 내지 도3은 본 발명의 단면 예시도 이다.1 to 3 are cross-sectional views of the present invention.

상기의 코어성분(1)은 바륨설포네이트 입자 함량이 코어성분(1)의 전체 중량대비 5~70중량%이고, 인 함량이 코어성분(1)의 전체중량 대비 0~0.7중량%가 되도록 난연성 인화합물이 함유되어 있는 열가소성 중합체이다.The core component (1) is flame retardant so that the barium sulfonate particle content is 5 to 70% by weight based on the total weight of the core component (1), and the phosphorus content is 0 to 0.7% by weight relative to the total weight of the core component (1). It is a thermoplastic polymer containing phosphorus compound.

상기 바륨설포네이트 입자의 입자크기는 0.3~0.6㎛인 것이 방사조업성 향상에 보다 바람직하다.Particle size of the barium sulfonate particles is more preferably 0.3 ~ 0.6㎛ to improve the spinning operation.

코어성분(1)의 단면적은 코어-시스형 복합섬유의 전체 단면적 대비 10~80%인 것이 바람직하다.The cross-sectional area of the core component (1) is preferably 10 to 80% of the total cross-sectional area of the core-sheath composite fiber.

코어성분(1)의 단면적 비율이 상기 범위를 벗어날 경우에는 코어-시스형 복합섬유의 단면형성성과 방사조업성이 저하될 수도 있다.When the ratio of the cross-sectional area of the core component 1 is out of the above range, the cross-sectional formability and spinning operation property of the core-sheath composite fiber may be deteriorated.

코어성분(1)내 바륨설포네이트 입자의 함량이 5중량% 미만을 경우에는 코어-시스형 복합섬유의 비중이 낮아져 드레이프성이 저하되고, 70중량%를 초과할 경우 에는 방사조업성이 저하된다.When the content of the barium sulfonate particles in the core component (1) is less than 5% by weight, the specific gravity of the core-sheath composite fiber is lowered, and the drape property is lowered. .

코어성분내 인 함량이 0.7중량%를 초과하는 경우에는 공중합에 의한 물성이 저하에 의해 연신공정시 사절이 생기기 쉬워 방사작업성이 나빠진다.When the phosphorus content in the core component exceeds 0.7% by weight, the threading property is liable to occur during the stretching process due to the decrease in physical properties due to copolymerization, resulting in poor spinning workability.

한편, 본 발명을 구성하는 시스성분(2)은 시스성분(2)의 전체중량 대비 인 함량이 0.05~3.0중량%인 열가소성 중합체 이다.On the other hand, the sheath component (2) constituting the present invention is a thermoplastic polymer having a phosphorus content of 0.05 to 3.0% by weight relative to the total weight of the sheath component (2).

아울러, 본 발명은 시스성분(2)내 인 함량이 코어성분(1)내 인 함량 보다 2,000ppm 이상 높은 것을 특징으로 한다. In addition, the present invention is characterized in that the phosphorus content in the cis component (2) is 2,000 ppm or more higher than the phosphorus content in the core component (1).

또한, 본 발명은 코어-시스형 복합섬유내 함유된 총 인 함량이 코어-시스형 복합섬유의 전체 중량 대비 0.15~2.0중량% 이다.In addition, in the present invention, the total phosphorus content contained in the core-sheath composite fiber is 0.15 to 2.0 wt% based on the total weight of the core-sheath composite fiber.

상기의 시스성분(2)내 인 함량이 0.05중량% 미만이거나, 시스성분(2)내 인 함량이 코어성분(1)내 인 함량 보다 2,000ppm 미만으로 높거나, 코어-시스형 복합섬유내에 함유된 총 인 함량이 0.15중량% 미만인 경우에는 초기연소에 대한 난연성이 저하된다.The phosphorus content in the sheath component (2) is less than 0.05% by weight, or the phosphorus content in the sheath component (2) is less than 2,000 ppm higher than the phosphorus content in the core component (1), or is contained in the core-sheath composite fiber If the total phosphorus content is less than 0.15% by weight, the flame resistance to initial combustion is lowered.

한편, 상기의 시스성분(2)내 인 함량이 3.0중량%를 초과하거나 코어-시스형 복합섬유내 함유된 인 함량이 2.0중량%를 초과하는 경우에는 공중합에 의한 물성저하에 의해 연신 공정시 사절이 생기기 쉬어 방사작업성이 저하된다.On the other hand, when the phosphorus content in the sheath component (2) is more than 3.0% by weight or the phosphorus content in the core-cis type composite fiber exceeds 2.0% by weight, the trimming process is performed during the stretching process due to the decrease of physical properties by copolymerization. This tends to occur and the workability of the spinning is lowered.

코어성분(1)과 시스성분(2)을 구성하는 열가소성 중합체는 각각 폴리에스테르 또는 폴리아미드 등 이다.The thermoplastic polymers constituting the core component (1) and the sheath component (2) are polyester or polyamide, respectively.

코어성분(1)과 시스성분(2)내에 함유된 난연성 인화합물은 하기 일반식(Ⅰ)의 히드록시 포스피닐 프로판산 유도체인 것이 난연성 및 방사조업성 향상에 보다 바람직하다.The flame retardant phosphorus compounds contained in the core component (1) and the cis component (2) are more preferably hydroxy phosphinyl propanoic acid derivatives of the following general formula (I) for the improvement of flame retardancy and spinning operability.
