본 발명은 분할형 극세사 부직포에 관한 것으로서, 더욱 상세하게는 분할형 극세사 섬유로 구성된 분할형 극세사 웹을 폴리 트리메틸렌테레프탈레이트(PTT)와 폴레 에틸렌테레프탈레이트(PET)가 접합된 복합PTT 섬유와 나일론 섬유 및 고수축성(High Shrinkage) 폴리에스테르 섬유와 혼섬하여 구성된 복합PTT 웹과 결합하여 부직포를 제조함으로써 외관 및 촉감이 뛰어날 뿐만 아니라 우수한 신축성과 뛰어난 원형복원성을 갖는 분할형 극세사 부직포에 관한 것이다.The present invention relates to a split microfiber nonwoven fabric, and more specifically, to a split microfiber web composed of split microfiber fibers, polytrimethylene terephthalate (PTT) and polyethylene terephthalate (PET) are bonded to composite PTT fibers and nylon. The present invention relates to a split-type microfiber nonwoven fabric having excellent elasticity and excellent circular resilience as well as excellent appearance and feel by producing a nonwoven fabric by combining with a composite PTT web composed of fibers and high shrinkage polyester fibers.
종이나 직물을 대체하는 피복재료로서 통상의 부직포는 천을 짜지 않고 원사를 적층시켜서 만들어 지는 피륙을 지칭하는 것으로서, 천연 또는 화학, 재생 등의 각종 섬유 소재를 상호간에 일정한 방향성 없이 엉키게 하여 시트(sheet)형태의 웹(Web)을 형성한 다음, 이를 화학적, 물리적인 방법으로 결합·안정화시키고 종이나 천과 같이 제조하여 산업 자재나 생활주변에서 그 사용 목적에 따라 광범위하게 활용되고 있다.As a coating material to replace paper or woven fabric, a conventional nonwoven fabric refers to a fabric made by laminating yarns without weaving cloth, and is entangled with various textile materials such as natural, chemical, recycled, etc. without having a certain direction. After forming the web in the form of), it is combined and stabilized by chemical and physical methods and manufactured like paper or cloth, and widely used in industrial materials or living environments according to its purpose of use.
특히, 천연피혁이 주된 소재로 사용되는 각종 가방, 의류, 공(Boll), 특히 신발 등의 소재가 점차 환경 친화적이면서 공해가 적고, 대량생산도 용이한 인조피 혁으로 대체되면서 부직포가 인조피혁의 소재로서 활용되고 있으며, 이에 따라 부직포의 품질 및 기능성을 향상시키고자 하는 연구가 활발히 이루어지고 있다.In particular, as non-woven fabrics are replaced by artificial leather, which is mainly made of natural leather, various materials such as bags, clothing, balls, and shoes are gradually replaced with artificial leather which is more environmentally friendly, less pollution, and easy to mass-produce. It is utilized as a material, and thus, researches to improve the quality and functionality of the nonwoven fabric have been actively conducted.
이 중, 극세섬유(micorofiber)를 이용하여 제조된 부직포는 비표면적 확대로 인해 탁월한 유연성, 감촉, 고흡액성, 와이핑 특성(wiping property)등의 잇점으로 인하여 광범위한 용도로 사용되고 있다. 섬유의 극세화가 이루어질수록 유연성과 부드러움이 증대되고 굽힘저항이 작아지게 되며, 부직포상에서 조직의 치밀화, 공극의 극소화가 얻어진다.Among them, nonwoven fabrics manufactured using microfibers have been used for a wide range of applications due to advantages such as excellent flexibility, feel, high absorbency, and wiping properties due to the expansion of the specific surface area. The finer the fibers, the greater the flexibility and softness, the smaller the bending resistance, and the denser the tissue and the smaller the voids on the nonwoven fabric.
극세섬유를 이용하여 제조된 부직포는 일반적으로 고가의 특수한 해도형 초극세사를 니들펀칭하여 3차원 교락구조를 만들고, 탄성과 통기성, 투습성을 부여하기 위하여 폴리우레탄 수지를 사용해서 마이크로 포러스(micro-porus)를 형성시킨다. 여기서 원료섬유로 이용되는 극세사는 일반적으로 1.0데니아 이하의 섬유이고, 이 섬유는 나일론과 폴리에스터, 폴리에스터와 코폴리에스터 또는 나일론과 폴리에틸렌 등의 두가지 성분의 섬유가 혼합된 이성분 해도사(sea-island)가 주로 사용되고 있다.Non-woven fabrics made of microfibers generally use needle punching of expensive special island-in-the-sea microfibers to create a three-dimensional entangled structure and use polyurethane resins to provide elasticity, breathability, and moisture permeability. To form. The microfibers used as the raw material fibers are generally 1.0 denier fibers or less, and the fibers are two-component islands-in-the-sea yarns in which two fibers such as nylon and polyester, polyester and copolyester, or nylon and polyethylene are mixed. -island) is mainly used.
이러한 방식으로 제조된 극세사 펠트는 폴리우레탄 수지를 함침한 후, 다시 응고, 워싱(washing), 건조공정을 거쳐 수산화나트륨 용액에 두개의 이성분 섬유 중의 한 성분을 용출해 내는 특수하고도 복잡한 공정을 거쳐 극세화된다. 이후 이렇게 제조된 극세사 펠트를 다시 버핑(buffing)한 후, 폴리우레탄수지를 표면에 코팅하면 0.05 ~ 0.1데니아를 갖는 부직포상의 인조피혁이 된다. The microfiber felt produced in this way is subjected to a special and complicated process of impregnating a polyurethane resin and then solidifying, washing and drying to elute one component of the two bicomponent fibers in a sodium hydroxide solution. It is fined after. After buffing the microfiber felt thus manufactured again, coating the polyurethane resin on the surface becomes a non-woven artificial leather having 0.05 ~ 0.1 denier.
이와 같이 만들어진 인조피혁은 부드러운 유연성과 세섬도로 인한 드레프트 성, 부피감, 투습성, 섬유간의 미세공간에 의한 보온성 등의 장점등을 갖는 천연피혁과 유사한 진피효과를 갖지만 값비싼 원료를 사용함에 의한 원가 부담, 극세화 하기 위한 수산화나트륨 용액에의 침적과 이성분 중에서 한 가지 성분을 용출시켜야 하는 복잡한 공정, 그로 인해 발생할 수 있는 환경폐수문제, 생산성 저하문제, 용출로 인해서 야기되는 극세사 펠트의 인장강도, 인열강도의 저하문제 등이 발생하는 문제점이 있었다.The artificial leather made in this way has a dermis effect similar to that of natural leather, which has the advantages of soft flexibility and fineness due to the fineness of draft, bulkiness, moisture permeability, and heat retention by micro-space between fibers, but the cost of using expensive raw materials Burden, the complex process of dipping in sodium hydroxide solution to elevate and eluting one of the two components, the environmental wastewater problem that may occur, the productivity problem, the tensile strength of the microfiber felt caused by elution, There was a problem such as a decrease in tear strength.

도 1은 본 발명의 일실시예에 따른 분할형 극세사 부직포의 단면 모식도이다.1 is a schematic cross-sectional view of a split microfiber nonwoven fabric according to an embodiment of the present invention.
도 1에 도시된 바와 같이, 본 발명에 따른 분할형 극세사 부직포(100)는 분할형 극세사 섬유로 이루어진 분할형 극세사 웹(110)과, 복합PTT 섬유와 고수축성 폴리에스테르섬유 및 일반 나일론 섬유가 혼섬되어 이루어진 복합PTT 웹(120)이 결합되어 형성된다. 이때, 표면층을 이루는 분할형 극세사 웹(100)은 10%~40%, 이면층을 이루는 복합PTT 웹(120)은 40%~90%의 중량비가 되도록 구성된다.As shown in FIG. 1, the split microfiber
분할형 극세사 웹(110)은 분할형 극세사 섬유 100%를 써멀본딩(Thermal Bonding)을 통해 평면시트상 웹으로 형성시킨 것으로, 상기 분할형 극세사 섬유는 분할전 1.5~4.0De의 섬도와 40mm~60mm의 섬유장을 갖는 섬유를 카드기를 통해 분할시켜, 분할후에는 0.01~0.2De의 섬도를 갖고 8~16분할의 형태를 이루는 분할형 극세사 섬유를 사용하며, 폴리에스테르가 80%~20%, 나일론이 80%~20%의 중량비가 되 도록 구성된다. 이러한 분할형 극세사는 해도형 극세사와는 달리 용출공정을 거치지 않고도 극세화를 이룰 수 있으며, 섬유밀도와 절단신도가 높아지는 우수한 물리적 성질을 가진다.The
복합PTT 웹(120)은 복합PTT 섬유와 고수축성 폴리에스테르 섬유 및 일반 나일론 섬유를 혼면하고, 카딩공정 및 예비 니들펀칭을 통해 평면시트상 웹으로 형성시킨 것이다. 이때, 복합PTT 섬유는 20%~40%, 고수축성 폴리에스테르 섬유는 20%~40%, 일반 나일론 섬유는 20%~40%의 중량비가 되도록 혼섬하는 것이 바람직하며, 이 범위를 벗어날 경우 부직포 제조시의 작업성 및 제품특성이 바람직하지 못하게 된다. 즉, 고수축 폴리에스테르 함량이 20%미만이면, 부직포가 용이하게 수축하지 않으며, 고수축 폴리에스테르 함량이 40%이상으로 과다하면 부직포가 과다하게 수축하여 인공피혁의 제조에 사용하는 것이 적합하지 않게 된다.The
여기서 복합PTT 섬유는 테레프탈산(Terephthalic Acid)과 프로판 디올(Propanediol, PDO)을 주성분으로 한 폴리 트리메틸렌테레프탈레이트(Poly Trimethyleneterephthalate; PTT)와 테레프탈산(Terephthalic Acid)과 에틸렌클리콜(Ethylene Glycol)을 주성분으로 한 폴리 에틸렌테레프탈레이트(Poly Ethyleneterephthalate; PET)를 중량비가 2:8 ~ 8:2가 되도록 방사하여, 폴리 폴리 트리메틸렌테레프탈레이트(PTT)와 폴리 에틸렌테레프탈레이트(PET)가 섬유의 길이 방향으로 바이메탈구조를 이루도록 제조된 원사이다.The composite PTT fiber is composed of poly trimethyleneterephthalate (PTT), terephthalic acid, and ethylene glycol (Ethylene Glycol), which are mainly composed of terephthalic acid and propanediol (PDO). Poly Ethylene terephthalate (PET) is spun to a weight ratio of 2: 8 to 8: 2, so that poly poly trimethylene terephthalate (PTT) and polyethylene terephthalate (PET) are bimetallic in the length direction of the fiber. It is a yarn manufactured to form a structure.
고수축 폴리에스테르(High Shrinkage Polyester)는 그 종류가 특별히 한정되지 않지만 1.4~3.0데니어의 섬도 및 40mm~60mm의 섬유장을 가지며, 열수 수축율이 90℃의 온도에서 10초동안 수축시켰을 때 40%~60%가 수축되는 것을 사용하도록 한다.High Shrinkage Polyester is not particularly limited in its kind, but has a fineness of 1.4 to 3.0 denier and a fiber length of 40 mm to 60 mm, and has a hydrothermal shrinkage of 40% when shrinked for 10 seconds at a temperature of 90 ° C. Use 60% shrinkage.

상기와 같이 써멀본딩을 통해 형성된 분할형 극세사 웹(110)과 니들펀칭으로 결합된 복합PTT 웹(120)을 니들펀칭기에 동시에 공급한 후 니들펀칭을 통해 분할형 극세사 웹(110)과 복합PTT 웹(120)을 결합시키고, 수축장치에 공급하여 수축시킨 뒤, 탈수공정, 롤러 코팅 처리, 건조, 열카렌더링 공정을 통해 최종 부직포를 얻는다. The
이때, 니들펀칭공정에서는 써멀본딩을 통해 형성된 분할형 극세사 웹(110)이 간헐적으로 한쪽으로 처지는 경우가 발생하여 분할형 극세사 웹(110)과 복합PTT 웹(120)의 결합시 부분적으로 분할형 극세사 웹(110)이 겹쳐지는 경우가 발생할 수 있으므로, 주름방지 장치를 펀칭기 전에 설치하여 분할형 극세사 웹(110)이 주름방지 장치를 통과하여 곧게 펴진 상태로 니들펀칭기에 공급되도록 한다. At this time, in the needle punching process, the
더불어, 수축과정에서는 폴리비닐알콜수지(PVA)가 3%~12%, 유연제가 1%~10% 용해된 열탕조의 열수용액에 담가 열수축 시킴으로써, 분할형 극세사 부직포 제품의 밀도가 높아짐과 동시에 극세사 효과도 극대화 되어 면평활성이 우수해지는 효과를 가지도록 한다.In addition, during shrinkage, the polyvinyl alcohol resin (PVA) is soaked in a hot water solution containing 3% to 12% of a polyvinyl alcohol resin and 1% to 10% of a softener.
