Description
본 발명은 폴리에스터 섬유에 관한 것으로서, 더욱 상세하게는 수축성과 심색성이 우수한 폴리에스터 섬유에 관한 것이다.The present invention relates to a polyester fiber, and more particularly to a polyester fiber excellent in shrinkage and deep colorability.
지금까지 알려진 기술로는 수축성이 우수한 폴리에스터용 폴리머 제조법과 심색사용 폴리머 제조법이 각각 알려져 있으나, 이 두 가지 기능을 동시에 만족시키는 폴리머를 제조하는 것은 어려웠다.Known techniques so far are known for producing polymers for shrinkage and polymers for deep color, respectively, but it is difficult to produce a polymer that satisfies both functions simultaneously.
따라서, 본 발명은 심색기능과 수축기능을 동시에 만족시키는 폴리머 조성물을 제조하여 수축성과 심색성이 우수한 폴리에스터 섬유를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a polyester fiber having excellent shrinkage and deep colorability by preparing a polymer composition that satisfies deep color and shrinkage functions simultaneously.
이하, 본 발명을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 폴리에틸렌테레프탈레이트를 주성분으로 하는 폴리에스터 섬유에 있어서 제3성분이 산성분에 대하여 3~10몰공중합되어 있고, 실리카 입자가 산성분에 대하여 0.3~3 중량혼합되어 있으며 비등 수축율이 12를 초과함을 특징으로 하는 폴리에스터 섬유에 관한 것이다.The present invention is a polyester fiber containing polyethylene terephthalate as a main component, the third component is 3 to 10 mol relative to the acid component Copolymerized, 0.3-3 weight silica particles with respect to acid component Mixed and boiling shrinkage 12 It relates to a polyester fiber characterized by exceeding.
이하, 본 발명을 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
본 발명에서는 폴리에스터사에 고수축성을 부여하기 위하여 폴리에스터 중합시에 공중합 단량체인 이소프탈레이트, 디메틸이소프탈레이트, 2,2-비스[4-(2-하이드록시)페놀]프로판, 1,4-사이클로헥산디메탄올, 네오펜틸글리콜 등의 성분을 단독 혹은 복합하여 원료성분에 대하여 일정한 몰비로 첨가하고, 심색성 기능을 부여시키기 위하여 일정한 입경을 가진 실리카 입자를 중합공정에서 일정한 함량을 첨가시켜 중합한 폴리머를 후가공함으로써 고수축성과 심색성이 우수한 폴리에스터 섬유를 제조할 수 있다.In the present invention, isophthalate, dimethyl isophthalate, 2,2-bis [4- (2-hydroxy) phenol] propane, 1,4- which are copolymerization monomers at the time of polyester polymerization in order to impart high shrinkage to the polyester yarn. Cyclohexanedimethanol, neopentylglycol, and other components are added alone or in combination to a certain molar ratio with respect to the raw materials, and silica particles having a constant particle size are added in a polymerization step to give a deep color function and then polymerized. By post-processing the polymer, polyester fibers excellent in high shrinkage and deep colorability can be produced.
수축성을 부여하는 공중합 단량체를 과량 투입한 경우에는 폴리머의 내열성과 실리카의 분산성을 약화시켜 방사성과 제사성이 불량하고 소량 첨가시에는 수축 기능면에서 부족한 문제점이 있으므로 최적 함량으로는 원료인 디메틸테레프탈레이트 혹은 테레프탈산 대비 3~10 몰로 첨가하는 것이 양호하였다.When excessive amount of copolymerization monomer giving shrinkage is added, the heat resistance of the polymer and the dispersibility of silica are weakened, so that the radioactivity and the sacrificial properties are poor. 3 to 10 moles of phthalate or terephthalic acid It was good to add as.
첨가량이 3몰미만일 경우에는 본 발명에서 요구하는 12를 초과하는 비등수축율을 달성할 수 없으며, 10몰%를 초과할 경우에는 폴리머의 점도 증가로 방사성 등에 영향을 미쳐 절사 등이 발생하여 방사 조업성이 떨어진다.3 mol of addition If less than 12 required by the present invention It is not possible to achieve a boiling shrinkage of more than 10%, and if it exceeds 10 mol%, the viscosity of the polymer is increased, affecting the radioactivity, etc., resulting in cuts and the like, resulting in poor spinning operability.
그리고 심색기능을 부여하기 위하여 첨가되는 실리카 입자의 경우는 입자 크기가 너무 클 경우 후가공 처리시 심색성과 방사성, 제사성이 부족하고, 입자가 너무 작을 경우에는 원료 산성분의 영향으로 인하여 쉽게 응집이 발생되어 조대입자를 생성하여 심색기능과 방사, 제사성이 불량한 결과를 보이므로 최적 크기로는 0.01~0.50㎛이고, 실리카 입자 첨가량은 원료 산성분에 대하여 0.3~3 중량가 가장 적합하였다.In the case of silica particles added to impart deep color function, the deep color, radioactivity, and desabilization are insufficient in post-processing if the particle size is too large, and if the particles are too small, aggregation occurs easily due to the influence of the raw acid component. As the coarse particles are produced, the deep color function, the spinning and the rusting property are poor, and thus the optimum size is 0.01 to 0.50 µm, and the silica particle addition amount is 0.3 to 3 weight based on the raw acid component. Was the most suitable.
실리카 입자 첨가량이 0.3 중량미만일 경우에는 원사표면에 미세한 요철을 발생시키기에 불충분하며, 본 발명에서 달성코자 하는 삼색효과에 도달할 수 없으며, 3중량를 초과할 경우에는 실리카 입자가 응집되어 조대입자 생성가능성이 높으며 이로 인해 용융방사시 팩(Pack)압이 상승되어 제사성 등에 문제가 발생한다.0.3 weight of silica particle addition If it is less than enough to generate fine irregularities on the surface of the yarn, it is not possible to reach the tricolor effect to achieve in the present invention, 3 weight If it exceeds, the silica particles are agglomerated to have a high possibility of generating coarse particles. This causes a problem such as sacrificiality due to an increase in pack pressure during melt spinning.
본 발명의 구수축성 심색사는 고수축사와 저수축사로 구성된 이수축 혼섬사의 코아(Core)사로 적용될 수 있으며, 그 이유는 비등수축율이 12보다 크기 때문이다. 반면 비등수축율이 12미만일 경우에는 이수축 혼섬 효과가 미흡해진다.Shrinkage deep color yarn of the present invention can be applied as core (Core) yarn of two-shrink blended yarn composed of high shrinkage yarn and low shrinkage yarn, because the boiling shrinkage rate is 12 Because it is bigger. Whereas the boiling contraction rate is 12 If less than this, the bi-shrink mixing effect is insufficient.
이하, 본 발명을 실시예를 통하여 더욱 구체적으로 설명하면 다음과 같은 바, 본 발명이 실시예로 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the following Examples, but the present invention is not limited to the Examples.
