Abstract
Description
본 발명은 폴리에테르에스테르계 복합중공섬유 및 이의 제조방법에 관한 것으로서 벌키성과 탄성회복율이 우수한 폴리에테르에스테르계 복합중공섬유 및 이의 제조방법에 관한 것이다.
The present invention relates to a polyether ester composite hollow fiber and a method for producing the same, and to a polyetherester composite hollow fiber having excellent bulkiness and elastic recovery rate, and a method for producing the same.
일반적으로 탄성중합체는 스판덱스로 통칭되는 폴리우레탄계 탄성중합체가 많이 사용되고 있다. 폴리우레탄 섬유는 분자구조내에 염착좌석이 없기 때문에 산성염료에 염색이 잘되지 않아 분산염료를 사용하여 염색을 하지만 산성염료에 비해 견뢰도가 현저히 떨어져 사용상의 문제점이 있으며, 열에 약하여 폴리아미드계 섬유나 폴리에스테르계 섬유 등 타소재와 혼방하여 사용시 고온 염색이 힘들고 직물제직 후의 후가공에도 제한이 많이 있다.In general, a polyurethane-based elastomer commonly referred to as spandex is used as the elastomer. Polyurethane fibers do not dye well in acid dyes because they do not have dye seats in their molecular structure, so they are dyed using disperse dyes. However, they have significantly lower fastness than acid dyes. When mixed with other materials such as ester fibers, high temperature dyeing is difficult to use and there are many limitations in post-processing after weaving the fabric.
또한, 폴리우레탄 섬유는 대기중에 노출되면 일광에 의하여 탄성섬유 고유의 물성 및 색상이 변하고, 대기중의 폐가스 등에 의해서도 쉽게 변색되며, 또 자연적인 외기에서도 쉽게 산화되어 그의 고유물성이 저하되어 그 자체로 직물의 원사로 사용할 수 없다.In addition, when the polyurethane fiber is exposed to the atmosphere, the physical properties and colors of elastic fibers change due to sunlight, and are easily discolored by waste gases in the atmosphere. Can not be used as a yarn for fabrics.
상기와 같은 폴리우레탄계 탄성중합체의 문제점으로 제조가 용이하고 제조단가가 저렴한 폴리에스테르계 탄성중합체의 개발이 진행되고 있으며, 현재 많은 폴리에스테르계 탄성중합체가 제조되고 있다. Due to the problems of the polyurethane-based elastomer as described above, the development of a polyester-based elastomer that is easy to manufacture and inexpensive to manufacture is progressing, and many polyester-based elastomers are currently manufactured.
대한민국 특허출원 제1996-0030520호에서는 하드 세그먼트(Hard segment)로 융점 240~280℃ 결정성 폴리에스테르, 소프트 세그먼트(Soft segment)로 분자량500~3000의 폴리테트라메틸렌글리콜(Polytetramethylene glycol: PTMG) 및 3관능이상의 가교제를 투입, 공중합하여 폴리에테르에스테르계 탄성체를 제조하였으나 폴리에테르에스테르계 탄성체의 고유점도(IV)가 너무 낮아 방사 작업성이 낮고 탄성회복율 또한 만족한 결과가 나오지 못하는 문제점이 있다.Korean Patent Application No. 1996-0030520 discloses a crystalline polyester having a melting point of 240-280 ° C. as a hard segment, a polytetramethylene glycol (PTMG) having a molecular weight of 500-3000 as a soft segment, and 3 The polyether ester elastomer was prepared by adding and copolymerizing a crosslinking agent having more than a functional level, but the intrinsic viscosity (IV) of the polyether ester elastomer was too low, resulting in low spinning workability and satisfactory elastic recovery.
또한, 대한민국 특허출원 제1996-080489호 등 다수의 문헌에서 폴리에테르에스테르계 탄성체의 중합방법으로 산성분으로 디메틸테레프탈레이트(Dimethyl Terephthalate: DMT)를 디올성분으로 1,4-부탄디올(1,4-Butanediol: 1,4-BD)과 폴리테트라메틸렌글리콜(Polytetramethylene glycol: PTMG)을 사용하고 있으나, 중합물질로 디메틸테레프탈레이트(DMT)를 사용할 경우, 중합반응 중 부산물로 메탄올이 유출되게 되는데 메탄올은 공기보다 가볍고 가연성이 있는 유독한 액체이기 때문에 별도의 회수 장치가 필요하고 인체 흡입 시 폼알데하이드라는 물질로 변환되어 인체에 치명적인 영향을 줄 수 있다.In addition, a number of documents, including Korean Patent Application No. 1996-080489, 1,4-butanediol (1,4- Butanediol: 1,4-BD) and Polytetramethylene glycol (PTMG) are used, but when dimethyl terephthalate (DMT) is used as a polymer, methanol is released as a by-product during the polymerization reaction. Lighter, flammable and toxic liquids require a separate recovery device and can be converted to a formaldehyde substance upon human inhalation, which can have a fatal effect on the human body.
또한, 디메틸테레프탈레이트(DMT)의 경우, 용해도는 높으나 반응 과정에서 쉽게 재결정화 되기 때문에 미반응물의 발생 빈도가 높고 중합공정에서 디메틸테레프탈레이트(DMT)의 재결정화 방지 관리가 필요하여 제조공정에 어려운 문제가 있었다.
In addition, dimethyl terephthalate (DMT) has high solubility, but is easily recrystallized during the reaction process, so unreacted substances are frequently generated, and dimethyl terephthalate (DMT) needs to be prevented from recrystallization in the polymerization process. There was a problem.

도 1은 본 발명의 바람직한 일실시예에 의한 중공복합섬유의 단면을 나타낸 개념도이다. 본 발명에 의한 중공복합섬유는 일반 PET(Polyester)계 성분(A)와 PEE(Polyetherester)계 엘라스토머 성분(B)으로 이루어질 수 있다. 상기 성분(A)와 성분(B)는 접촉계면(110) 상에 30 내지 60%가 접하도록 설계될 수 있다. 양 성분간의 계면접촉에 의한 복합섬유의 형상안정성과 후술할 중공부(H)의 공간면적의 확보를 위해 상기 범위가 바람직하다. 1 is a conceptual diagram showing a cross-section of a hollow composite fiber according to an embodiment of the present invention. Hollow composite fiber according to the present invention may be composed of a general PET (Polyester) -based component (A) and PEE (Polyetherester) -based elastomer component (B). The components (A) and (B) may be designed to be in contact with 30 to 60% on the
상기 성분(A)와 성분(B)의 면적비는 1 내지 5 : 1이 바람직한데 상기 범위내에서 방사금구의 팽윤차에 의해 사이드 바이 사이드형의 단면형성이 유지되고 크림프 발현이 이루어진다. 특히 성분(A)의 면적이 상기 범위를 초과할 경우 탄성을 나타내는 성분(B)의 면적이 적어져 목적하는 물성을 즉 벌키성과 탄성회복률을 달성할 수 없는 문제점이 있다. The area ratio of the component (A) and the component (B) is preferably 1 to 5: 1, but the side by side cross-sectional formation is maintained by the swelling difference of the spinneret within the above range, and the crimp expression is achieved. In particular, if the area of the component (A) exceeds the above range, the area of the component (B) exhibiting elasticity is small, and thus there is a problem that the desired physical properties, that is, bulkiness and elastic recovery rate cannot be achieved.
상기 성분(A)는 일반적인 폴리에스테르계 섬유를 사용할 수 있다. 이 경우 고유점도가 0.5 내지 0.7dl/g인 성분을 사용함이 바람직하다. 상기 성분(B)는 하드세그먼트와 소프트세그먼트로 이루어진 공중합체일 수 있으며, 고유점도가 0.9 내지 1.6dl/g인 성분을 사용할 수 있다. 상기 범위 내에서 성분(A)와 성분(B)는 계면에서의 상용성이 좋고 사이드바이사이드 형태로 방사시 미리 설계된 섬유 단면형상을 발현할 수 있다. 한편 성분(B)는 Tm이 140 내지 170℃이고 탄성회복률이 70% 이상임이 바람직하다. As said component (A), a general polyester fiber can be used. In this case, it is preferable to use a component having an intrinsic viscosity of 0.5 to 0.7 dl / g. The component (B) may be a copolymer consisting of a hard segment and a soft segment, and a component having an intrinsic viscosity of 0.9 to 1.6 dl / g may be used. Within this range, component (A) and component (B) have good compatibility at the interface and can express a pre-designed fiber cross-sectional shape when spinning in the form of side byside. On the other hand, it is preferable that component (B) has Tm of 140-170 degreeC and elastic recovery rate is 70% or more.
성분(B)는 다양한 성분으로 제조될 수 있으나 비제한적인 예로서 하기 화학식과 같은 구조로 형성될 수 있다.
Component (B) may be made of various components, but may be formed as a structure such as the following formula as a non-limiting example.

또한 상기 중공부(H)는 성분(A)와 성분(B)의 고유점도 차로 인해 전체 섬유단면 대비 2 내지 20%의 면적비로 형성될 수 있다. 중공부(H)가 상기 범위 내일 때 벌키성과 중공형태성이 유지되는 것으로 시험되었다. 또 이 범위내에서 본 발명에 의한 섬유의 일 활용예인 부직포나 쿠션재로 사용될 경우 흡음성이나 탄력회복성에도 영향을 미치는 것으로 분석되었다. In addition, the hollow portion (H) may be formed with an area ratio of 2 to 20% of the total fiber cross-section due to the difference in intrinsic viscosity of the component (A) and component (B). It was tested that the bulkiness and hollow formability were maintained when the hollow portion H was in the above range. In addition, when used as a non-woven fabric or a cushioning material that is an example of the use of the fiber according to the present invention within this range it was analyzed to affect the sound absorption or elastic recovery.
본 발명에 의한 섬유는 성분(A)와 성분(B)를 각각 용융하여 중공의 사이드바이사이드형으로 복합방사하고 제1연신단계에서 40 내지 80℃로, 제2연신단계는 90 내지 160℃로 진행하되 총 연신비를 1.9 내지 3.8로 제어할 수 있다. 또한 크림프율를 9 내지 13개/m로 형성한 후 70 내지 130℃에서 열처리할 수 있다. The fiber according to the present invention melts component (A) and component (B), respectively, and spuns the composite into a hollow side-by-side type at 40 to 80 ° C. in the first drawing step, and the second drawing step to 90 to 160 ° C. Proceed to control the total draw ratio from 1.9 to 3.8. In addition, after forming a crimp rate of 9 to 13 / m, it can be heat-treated at 70 to 130 ℃.
상기 생성된 중공복합섬유는 용도에 따라 후가공처리를 할 수 있음은 물론이며 특히 부직포나 쿠션재로 사용될 경우 단섬유로 커팅될 수 있다. The resultant hollow composite fiber can be post-processed according to the use, of course, can be cut into short fibers, especially when used as a nonwoven fabric or cushioning material.
