Abstract
Description
본 발명은 부직포 바인더로 사용할 수 있는 열접착 복합섬유에 관한 것으로 중공형으로 형성되어 경량성, 벌키성, 흡음성 및 보온성 등의 다기능성을 가지는 다기능성 열접착 복합섬유 에 관한 것이다.
The present invention relates to a thermally adhesive conjugated fiber which can be used as a nonwoven binder, and is formed into a hollow form, and relates to a multifunctional thermally adhesive conjugated fiber having multifunctional properties such as light weight, bulky property, sound absorbing property and warming property.
열접착 복합섬유는 열풍등의 열에너지를 이용하여, 열융착에 의하여 부직포를 제조할 수 있다. 열접착형 복합섬유는 일반적으로 2성분으로 구성되고, 열에 의해 1성분만을 용융시킴으로써 섬유끼리의 접착을 통해 벌키한 부직포를 용이하게 얻을 수 있어서 산업자재에 널리 이용되고 있다. 폴리 에스테르계 열접착형 복합섬유는 자동차용, 건축자재용, 위생재용등의 생활용품이나 필터용 부직포로 널리 사용되고 있다.The heat-bondable composite fiber can be produced by heat fusion using thermal energy such as hot air. The heat-bondable conjugate fiber is generally composed of two components, and by melting only one component by heat, a bulk nonwoven fabric can be easily obtained through bonding of the fibers, and thus it is widely used in industrial materials. BACKGROUND ART [0002] Polyester thermally adhesive type conjugated fibers are widely used as household articles such as automobiles, building materials, sanitary materials, and nonwoven fabrics for filters.
일반적으로 폴리에스테르계 열접착형 복합섬유는 일반 폴리에스테르를 제1성분으로 하여 코어(core)를 형성하고, 테레프탈산을 포함하는 디카르본산 성분과 에틸렌글리콜을 포함하는 디올성분이 축중합된 공중합 폴리에스테르를 제2성분으로 하여 시스(sheath)를 형성하여 구성된다. 융점이 서로 다른 상기 2 성분 열접착형 복합섬유는 코어-시스 형태뿐만 아니라, 병렬형태, 분할형태 등으로도 적용이 가능하다. 또한 코어-시스 형태도 코어-시스 정심형태와 코어-시스 편심형태로 제조될 수 있다. 한편, 섬유의 단면형태는 원형 또는 원형이 아닌 이형단면일 수 있다. Generally, the polyester-based heat-bonding type conjugate fiber is produced by forming a core by using a general polyester as a first component, forming a core by copolymerization of a copolymer polyol having a condensation product of a dicarboxylic acid component containing terephthalic acid and a diol component containing ethylene glycol And an ester is used as a second component to form a sheath. The two-component heat-bondable composite fibers having different melting points can be applied not only to the core-sheath form, but also to the parallel form, the split form, and the like. The core-sheath form can also be manufactured in the form of core-sheath concentricity and core-sheath eccentricity. On the other hand, the cross-sectional shape of the fibers may be a circular cross-section or a non-circular cross-section.
미국특허 제4,065,439호에서는 테레프탈산/이소프탈산/아디핀산(또는 세바신산) 및 에틸렌글리콜/네오펜틸글리콜을 사용하여 저융점 폴리에스테르를 제조하는 방법을 제시하였으나 이 경우에는 얻어진 접착제의 융점이 45℃ 내지 60℃로 매우 낮아 의류용 심지로는 사용하기 곤란한 단점이 있다.U.S. Patent No. 4,065,439 discloses a method for producing a low melting point polyester by using terephthalic acid / isophthalic acid / adipic acid (or sebacic acid) and ethylene glycol / neopentyl glycol. In this case, however, It is very low at 60 ° C and it is difficult to use it as a wick for a garment.
영국 특허 제788,377호, 일본 특개평 제8-143,657호 및 한국 공고특허 제96-9776호 등에서는 비결정질의 분자구조를 구현할 수 있는 다른 공중합 물질로서 카르복실기의 위치가 이소프탈산의 메타 위치보다 분자 사슬을 더 구부릴수 있는 오 르소 위치의 프탈산 또는 무수프탈산을 사용하여 중합하려는 시도가 있어 왔다. 그러나 무수프탈산의 경우 공중합체내 함량이 높아질수록 유리전이온도의 강하 현상이 커서 연신 공정, 제품운반이나 적하시 섬유간 융착 발생될 수 있는 문제가 있다.U.S. Patent No. 788,377, Japanese Patent Application Laid-Open No. 8-143,657, and Korean Patent Publication No. 96-9776 disclose that other carboxylate materials capable of realizing an amorphous molecular structure have a carboxyl group position rather than a meta position of isophthalic acid Attempts have been made to polymerize using more or less bendable ortho-position phthalic acid or phthalic anhydride. However, in the case of phthalic anhydride, the higher the content in the copolymer, the greater the drop in the glass transition temperature, which may lead to the fusion of the fibers during the drawing process, product transportation or dropping.
또한, 최근에는 자동차용, 건축자재용, 위생재용등과 같은 부직포의 성능이 다양화되면서 경량성, 벌키성, 흡음성, 보온성과 같은 기능이 강조되고 있다, 따라서, 부직포 바인더용으로 적합하고 경량성, 벌키성, 흡음성, 보온성 등의 다기능을 갖는 복합섬유 개발이 시급한 실정이다.

도 1에서와 같이 본 발명에 따른 다기능성 열접착 복합섬유는 시스부와 코어부를 갖는 중공형 시스-코어형 열접착 복합섬유이다.As shown in FIG. 1, the multifunctional thermally adhesive composite fiber according to the present invention is a hollow cis-core type thermally adhesive composite fiber having a sheath portion and a core portion.
상기 코어부는 폴리에스테르 수지로형성될 수 있다.The core portion may be formed of a polyester resin.
상기 폴리에스테르 수지는 폴리에틸렌테레프탈레이트(Polyethyleneterephthalate, PET), 폴리부틸렌테레프탈레이트(Polybutylene terephthalate, PBT), 폴리트리메틸렌테레프탈레이트(Poly Trimethyleneterephthalate, PTT) 중 어느 하나를 사용할 수 있을 것이다.The polyester resin may be any one of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polytrimethylene terephthalate (PTT).
상기 폴리에스테르 수지의 고유점도가 높으면 중공형 시스-코어형 열접착 복합섬유 제조시 코어부 내의 중공형태가 내원방향으로 몰림현상이 증가하여 중공율도 감소할 수 있으므로 상기 코어부를 형성하는 폴리에스테르의 고유점도는 0.50~0.64dL/g인 것이 바람직할 것이다.If the intrinsic viscosity of the polyester resin is high, the hollow shape in the core portion in the core portion may be increased in the direction of the inner circumference during the production of the hollow cis-core type thermally adhesive composite fiber, and the hollow ratio may be decreased. The viscosity is preferably 0.50 to 0.64 dL / g.
